The adaptive-optics (AO) system at the W. M. Keck Observatory is characterized. We calculate the error budget of the Keck AO system operating in natural guide star mode with a near-infrared imaging camera. The measurement noise and bandwidth errors are obtained by modeling the control loops and recording residual centroids. Results of sky performance tests are presented: The AO system is shown to deliver images with average Strehl ratios of as much as 0.37 at 1.58 microm when a bright guide star is used and of 0.19 for a magnitude 12 star. The images are consistent with the predicted wave-front error based on our error budget estimates.

Photon-Weighted Midpoint Exposure Meter for Keck/HIRES Extrasolar Planet Research

NASA Technical Reports Server (NTRS)

1999-01-01

NASA Grant was received for research involving the construction of a photon-weighting midpoint exposure meter for the Keck HIRES spectrometer, and for support of our NASA/Keck-based planet research with this instrumentation. The research funds were also to be used to make our iodine cell calibration system and exposure meter available to the NASA Keck observing community. Progress this past year, the second of the 3-year granting period, involved work in 4 areas: 1) Further construction of the midpoint exposure meter. 2) Assisting observers with use of the Iodine system. 3) Acquisition of precision radial velocity data on our program star sample with continued monitoring to proceed in subsequent years as available telescope time permits. 4) Reduction and analysis of incoming precision radial velocity data to reject problematic and uninteresting program stars, and to identify promising planet candidates.

The Keck Cosmic Web Imager (KCWI) is a new facility instrument being developed for the W. M. Keck Observatory and funded for construction by the Telescope System Instrumentation Program (TSIP) of the National Science Foundation (NSF). KCWI is a bench-mounted spectrograph for the Keck II right Nasmyth focal station, providing integral field spectroscopy over a seeing-limited field up to 20" x 33" in extent. Selectable Volume Phase Holographic (VPH) gratings provide high efficiency and spectral resolution in the range of 1000 to 20000. The dual-beam design of KCWI passed a Preliminary Design Review in summer 2011. The detailed design of the KCWI blue channel (350 to 700 nm) is now nearly complete, with the red channel (530 to 1050 nm) planned for a phased implementation contingent upon additional funding. KCWI builds on the experience of the Caltech team in implementing the Cosmic Web Imager (CWI), in operation since 2009 at Palomar Observatory. KCWI adds considerable flexibility to the CWI design, and will take full advantage of the excellent seeing and dark sky above Mauna Kea with a selectable nod-and-shuffle observing mode. In this paper, models of the expected KCWI sensitivity and background subtraction capability are presented, along with a detailed description of the instrument design. The KCWI team is lead by Caltech (project management, design and implementation) in partnership with the University of California at Santa Cruz (camera optical and mechanical design) and the W. M. Keck Observatory (program oversight and observatory interfaces). The optical design of the blue camera for the Keck Cosmic Web Imager (KCWI) by Harland Epps of the University of California, Santa Cruz is a lens assembly consisting of eight spherical optical elements. Half the elements are calcium fluoride and all elements are air spaced. The design of the camera barrel is unique in that all the optics are secured in their respective cells with an RTV annulus without additional hardware

The Impacts of Military, Industrial, and Private Support on Modern Astronomy

NASA Astrophysics Data System (ADS)

Harwit, Martin

2015-01-01

In contrast to the period following WW I, governmental support for astronomy grew enormously after WWII and during the Cold War. In spite of reservations expressed by leading astronomers like Harlow Shapley at Harvard and Otto Struve at Yerkes, tools provided by the military took astronomy into directions neither Shapley nor Struve could possibly have imagined — radio, X-ray, gamma-ray and infrared astronomy. It was a great ride that lasted half a century. Had it been up to Shapley and Struve, they would have opted for a return to where pre-war optical astronomy had left off — themes over which they could exert personal control.The problem today, however, as I will show, is that the directions the military supported, while still fruitful, may be keeping us from vigorously pursuing new problems astrophysics needs to consider, the nature of dark energy and dark matter, or the pursuit of intelligent life elsewhere in the universe, none of which appear of interest to the military or industry. Topics of this kind could be supported by the very rich, like Yerkes and Hooker in the past, the Keck Foundation and Paul Allen more recently, or by less affluent but highly skilled volunteers. Support by the wealthy has occasionally been questioned, as in a front page article by William Broad in the International New York Times on March 17, 2014, in which he worried that the ultrarich would likely be idiosyncratic and know too little. Whether this fear is justified can be debated. However, failing this kind of philanthropic support, astronomy might opt for aid through the recently developed "economy of the commons,' pioneered by Elinor Ostrom, which tends to succeed by world-wide support on smaller scales coordinated largely through the internet. This movement is sometimes referred to as crowd sourcing. It tends to attract thoughtful, like-minded individuals from across the globe who wish to contribute their skills and have the required talents.I will review both the great

KPF is a fiber-fed, high-resolution, high-stability spectrometer in development at the UC Berkeley Space Sciences Laboratory for the W.M. Keck Observatory. The instrument is designed to characterize exoplanets via Doppler spectroscopy with a single measurement precision of 0.5ms-1 or better, however its resolution and stability will enable a wide variety of astrophysical pursuits. KPF will have a 200mm collimated beam diameter and a resolving power of >80,000. The design includes a green channel (440nm to 590 nm) and red channel (590nm to 850 nm). A novel design aspect of KPF is the use of a Zerodur optical bench, and Zerodur optics with integral mounts, to provide stability against thermal expansion and contraction effects.

In the central parsec of the Milky Way Galaxy the environment of the super-massive black hole (SMBH) presents a complicated mixture of stars, gas, and dust. These inner few tens of arcseconds of the GC have been observed at high resolution with Keck for 20 years with the primary goal of monitoring stars orbiting the SMBH. However, the gas features and their dynamics can also be closely examined using this unique baseline of data. In particular, observations with the Keck OSIRIS integral field spectrometer allow us to examine of the dynamical properties of the gas and to possibly identify new “G-type” objects, or dusty stellar objects. We present a study of morphology and orbital dynamics of sub-parsec scale gas features in the central region.

The Keck keyword layer

NASA Technical Reports Server (NTRS)

Conrad, A. R.; Lupton, W. F.

1992-01-01

Each Keck instrument presents a consistent software view to the user interface programmer. The view consists of a small library of functions, which are identical for all instruments, and a large set of keywords, that vary from instrument to instrument. All knowledge of the underlying task structure is hidden from the application programmer by the keyword layer. Image capture software uses the same function library to collect data for the image header. Because the image capture software and the instrument control software are built on top of the same keyword layer, a given observation can be 'replayed' by extracting keyword-value pairs from the image header and passing them back to the control system. The keyword layer features non-blocking as well as blocking I/O. A non-blocking keyword write operation (such as setting a filter position) specifies a callback to be invoked when the operation is complete. A non-blocking keyword read operation specifies a callback to be invoked whenever the keyword changes state. The keyword-callback style meshes well with the widget-callback style commonly used in X window programs. The first keyword library was built for the two Keck optical instruments. More recently, keyword libraries have been developed for the infrared instruments and for telescope control. Although the underlying mechanisms used for inter-process communication by each of these systems vary widely (Lick MUSIC, Sun RPC, and direct socket I/O, respectively), a basic user interface has been written that can be used with any of these systems. Since the keyword libraries are bound to user interface programs dynamically at run time, only a single set of user interface executables is needed. For example, the same program, 'xshow', can be used to display continuously the telescope's position, the time left in an instrument's exposure, or both values simultaneously. Less generic tools that operate on specific keywords, for example an X display that controls optical

Near-Infrared Keck Interferometer and IOTA Closure Phase Observations of Wolf-Rayet stars

NASA Astrophysics Data System (ADS)

Rajagopal, J.; Wallace, D.; Barry, R.; Richardson, L. J.; Traub, W.; Danchi, W. C.

We present first results from observations of a small sample of IR-bright Wolf-Rayet stars with the Keck Interferometer in the near-infrared, and with the IONIC beam three-telescope beam combiner at the Infrared and Optical Telescope Array (IOTA) observatory. The former results were obtained as part of shared-risk observations in commissioning the Keck Interferometer and form a subset of a high-resolution study of dust around Wolf-Rayet stars using multiple interferometers in progress in our group. The latter results are the first closure phase observations of these stars in the near-infrared in a separated telescope interferometer. Earlier aperture-masking observations with the Keck-I telescope provide strong evidence that dust-formation in late-type WC stars are a result of wind-wind collision in short-period binaries.Our program with the Keck interferometer seeks to further examine this paradigm at much higher resolution. We have spatially resolved the binary in the prototypical dusty WC type star WR 140. WR 137, another episodic dust-producing star, has been partially resolved for the first time, providing the first direct clue to its possible binary nature.We also include WN stars in our sample to investigate circumstellar dust in this other main sub-type of WRs. We have been unable to resolve any of these, indicating a lack of extended dust.Complementary observations using the MIDI instrument on the VLTI in the mid-infrared are presented in another contribution to this workshop.

Astronomy in the City for Astronomy Education

NASA Astrophysics Data System (ADS)

Ros, Rosa M.; Garc, Beatriz

Astronomy is part of our culture. Astronomy cannot be isolated in a classroom, it has to be integrated in the normal life of teachers and students. ``Astronomy in the city'' is an important part of NASE (Network for Astronomy School Education) (Ros & Hemenway 2012). In each NASE course we introduce a ``working group session'' chaired by a local expert in cultural astronomy. The chair introduces several examples of astronomy in their city and after that, the participants have the opportunity to discuss and mention several similar examples. After this session all participants visit one or two sites proposed and introduced by the chair. After more than 5 years using this method we visited and discovered several examples of astronomy in the city: •Astronomy in ancient typical clothes. •Archaeological temples oriented according to the sunrise or set. •Petroglyphs with astronomical meaning. •Astronomy in monuments. •Sundials. •Oriented Colonial churches. •Astronomy in Souvenirs. In any case, teachers and students discover that Astronomy is part of their everyday life. They can take into account the Sun's path when they park their car or when they take a bus ``what is the best part in order to be seat in the shadow during the journey?'' The result is motivation to go with ``open eyes'' when they are in the street and they try to get more and more information about their surroundings. In summary, one of the main activities is to introduce local cultural aspects in NASE astronomy courses. The participants can discover a new approach to local culture from an astronomical point of view.

In support of the NASA/ESA Rosetta mission’s plans to observe asteroid (21) Lutetia during a 2010 July flyby, and in conjunction with a larger ground-based plus HST campaign to support this mission, we observed Lutetia from Keck and Gemini-North during several nights spanning 2008 Oct through 2009 Jan. Observations were made using adaptive optics in the near-IR, primarily at K-band (2.1 micron), and were timed to coincide with the asteroid's most recent opposition at a distance of about 1.4 AU. From these data, we determined Lutetia’s triaxial size and shape to be 132 x 101 x 76 km, with maximum expected uncertainties of 4 x 3 x 31 km. The spin pole is found to be at (RA, Dec) = (48, +9) deg or ecliptic (long, lat) = (49,-8) deg, with a formal uncertainty radius (not including systematics) of 3 deg. We have calibrated our technique of deriving dimensions of asteroids from AO images against Pluto and 4 satellites of Saturn with accurate diameters, and we expect that our systematics (included in the size uncertainties above) are no more than 3%. We also searched for satellites and our preliminary results indicate no detection of a satellite larger than about 1 km over a significant fraction of the Hill sphere (10-240 asteroid radii). Improved limits are expected from a more refined analysis. We are grateful for telescope time made available to us by S. Kulkarni and M. Busch (Cal Tech) for a portion of this dataset. We also thank our collaborators on Team Keck, the Keck science staff, for making possible some of these observations and for observing time granted at Gemini under NOAO time allocation.

2014-05-01

By the end of 2013, the Keck Observatory Archive (KOA) will serve data from all active instruments on the Keck Telescopes. OSIRIS (OH-Suppressing Infra-Red Imaging Spectrograph), the last active instrument to be archived in KOA, has been in use behind the (AO) system at Keck since February 2005. It uses an array of tiny lenslets to simultaneously produce spectra at up to 4096 locations. Due to the complicated nature of the OSIRIS raw data, the OSIRIS team developed a comprehensive data reduction program. This data reduction system has an online mode for quick real-time reductions, which are used primarily for basic data visualization and quality assessment done at the telescope while observing. The offline version of the data reduction system includes an expanded reduction method list, does more iterations for a better construction of the data cubes, and is used to produce publication-quality products. It can also use reconstruction matrices that are developed after the observations were taken, and are more refined. The KOA team is currently utilizing the standard offline reduction mode to produce quick-look browse products for the raw data. Users of the offline data reduction system generally use a graphical user interface to manually setup the reduction parameters. However, in order to reduce and serve the 200,000 science files on disk, all of the reduction parameters and steps need to be fully automated. This pipeline will also be used to automatically produce quick-look browse products for future OSIRIS data after each night's observations. Here we discuss the complexities of OSIRIS data, the reduction system in place, methods for automating the system, performance using virtualization, and progress made to date in generating the KOA products.

The W. M. Keck Exoplanet Tracker is a precision Doppler radial velocity instrument based on dispersed fixed-delay interferometry (DFDI) which takes advantage of the new technique to allow multi-object RV surveying. Installed at the 2.5m Sloan telescope at Apache Point Observatory, the combination of Michelson interferometer and medium resolution spectrograph allows design for simultaneous Doppler measurements of up to 60 targets, while maintaining high instrument throughput. Using a single-object prototype of the instrument at the Kitt Peak National Observatory 2.1m telescope, we previously discovered a 0.49MJup planet, HD 102195b (ET-1), orbiting with a 4.11d period, and other interesting targets are being followed up. From recent trial observations, the Keck Exoplanet Tracker now yields 59 usable simultaneous fringing stellar spectra, of a quality sufficient to attempt to detect short period hot-Jupiter type planets. Recent engineering improvements reduced errors by a factor of 2, and typical photon limits for stellar data are now at the 30m/s level for magnitude V 10.5 (depending on spectral type and v sin i), with a best value of 6.9m/s at V=7.6. Preliminary RMS precisions from solar data (daytime sky) are around 10m/s over a few days, with some spectra reaching close to their photon limit of 6-7m/s on the short term ( 1 hour). A number of targets showing interesting RV variability are currently being followed up independently. Additional engineering work is planned which should make for further significant gains in Doppler precision. Here we present the latest results and updates from the most recent engineering and observing runs with the Keck ET.

Two Decades (almost) of Keck Observations of Io

2015-12-01

We have regularly observed Io with the 10-m Keck Telescope since 1998, initially using the speckle imaging technique, and switching to Adaptive Optics techniques when this became available in 2001. In this talk we will discuss several eruptions that we witnessed, and present 20-30 year timelines of thermal emission from Pele, Pillan, Janus Patera, Kanehekili Fluctus, and Loki Patera, updating timelines in recent publications [1, 2] with additional Keck adaptive optics data obtained between 2002 and 2015. These new timelines are the most comprehensive plots ever produced of the volcanic thermal emission variability for these or any other locations on Io, utilizing data from multiple ground- and space-based assets. Our continuing multi-decadal observing program forms the basis for charting the variability of Io's volcanic activity, of great importance for understanding the evolution of the Galilean satellite system, and with the expectation of new missions to the jovian system in the next decade.

Pushing Glass: Engaging Young People in Astronomy Through Amateur Mirror Making Classes

NASA Astrophysics Data System (ADS)

Larsen, Kristine; Slater, K.; Drew, B.

2008-05-01

More than any other science, astronomy has benefited from the work of well-trained, enthusiastic and dedicated amateurs. In an online survey of more than 1100 amateur astronomers conducted by Storksdieck et al., 63% of respondents reported being engaged in educational outreach. Such activities aid in the recruitment of young members to amateur associations in an attempt to stem the well-known "graying” of the field. One of the activities utilized by amateur astronomy groups to excite both young people and the general public about astronomy is mirror and telescope making. In 1925, Arctic explorer, architect, and optical and mechanical designer Russell Porter asked an interviewer, "Why not make your own telescope? Astronomy would mean a lot more to you if you did.” Today, the Springfield Telescope Makers of Vermont carry on their founder's tradition of promoting amateur telescope making and the enjoyment of the night sky through regular mirror making classes. Among the target groups included in these classes are young people, some still in elementary school. In doing so, the STMs capitalize on research which demonstrates that interest in astronomy not only peaks around the transition between elementary and middle school, but also that the widely-reported gender gap in achievement and interest in science begins at this crucial juncture. This poster reports on the results of a study of mirror making classes conducted by the STMs and nine other amateur astronomy groups in the Northeast U.S., including class organizers’ reflections on their successes and challenges in recruiting and retaining young men and women through the completion of a workable telescope mirror.

The Williams College-MIT collaboration has observed numerous occultations of stars by Pluto/Charon and other Kuiper-belt objects (www.stellaroccultations.info), since its establishment three decades ago with an attempted discovery of Neptune's rings in 1983. In this paper, we describe several recent occultation observations, both successful and (for reasons of path uncertainties and/or weather) unsuccessful. Light curves made or arranged by Williams College faculty and students were used together with light curves by MIT colleagues and others to study Pluto's atmosphere and Charon's size, to discover one of the highest-known solar-system albedos (KBO 55636), and to attempt to study 1000-km-diameter Quaoar. Observations discussed include light curves for KBO 55636 on 9 October 2009 from Hawaii; Pluto on 3/4 July 2010 from Chile, 22 May 2011 from Williamstown, Massachusetts, 23 June 2011 from Hawaii (in support of SOFIA observations of Pluto's atmosphere, discussed in an article in press in AJ and of the pair of Pluto/Charon occultations of the same star), and 4 May 2013 (Bosh et al., this conference) and 15 July 2013 from Williamstown; Charon on 15 June 2013 from Williamstown; Quaoar from a picket fence ranging from Chile through Venezuela (with a detection there) to Massachusetts on July 8/9 and in South Africa on 12 July 2013.

Among various scenarios proposed to explain the nature of the outburst, the most promising is a stellar merger event. In this paper, we investigate the observational properties of the star and its surroundings in the post outburst phase. We have obtained a high-resolution optical spectrum of V838 Mon in 2005 October using the Keck I telescope. We have identified numerous atomic features and molecular bands present in the spectrum and provided an atlas of those features. In order to improve the spectrum interpretation, we have performed simple modeling of the molecular bands. Our analysis indicates that the spectrum is dominated by molecular absorption features arising in photospheric regions with temperatures of ~2400 K and in colder outer layers, where the temperature decreases to ~500 K. A number of resonance lines of neutral alkali metals are observed to show P Cygni profiles. Particularly interesting are numerous prominent emission lines of [Fe II]. All of them show practically the same profile, which can be well described by a Lorentzian profile. In the blue part of the spectrum, photospheric signatures of the B-type companion are easily seen. We have fitted the observed spectrum with a synthetic one and the obtained parameters are consistent with the B3V type. We have also estimated radial and rotational velocities of the companion. The data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation.

The Keck Observatory Archive (KOA), a collaboration between the NASA Exoplanet Science Institute and the W. M. Keck Observatory, serves science and calibration data for all active and inactive instruments from the twin Keck Telescopes located near the summit of Mauna Kea, Hawaii. In addition to the raw data, we produce and provide quick look reduced data for four instruments (HIRES, LWS, NIRC2, and OSIRIS) so that KOA users can more easily assess the scientific content and the quality of the data, which can often be difficult with raw data. The reduced products derive from both publicly available data reduction packages (when available) and KOA-created reduction scripts. The automation of publicly available data reduction packages has the benefit of providing a good quality product without the additional time and expense of creating a new reduction package, and is easily applied to bulk processing needs. The downside is that the pipeline is not always able to create an ideal product, particularly for spectra, because the processing options for one type of target (eg., point sources) may not be appropriate for other types of targets (eg., extended galaxies and nebulae). In this poster we present the design and implementation for the current pipelines used at KOA and discuss our strategies for handling data for which the nature of the targets and the observers' scientific goals and data taking procedures are unknown. We also discuss our plans for implementing automated pipelines for the remaining six instruments.

Optical and IR applications in astronomy and astrophysics

2009-06-01

The set comprising silicon charge-coupled devices, low band-gap infrared arrays and bolometer arrays provide astronomers with position-sensitive photon detectors from the X-ray to the sub-mm. In recent years the most significant advances have occurred in the near-infrared part of the spectrum because not only have the detector formats caught up with those of charge-coupled device (CCDs) but also because the advent of adaptive optics (AO) has meant that the very largest telescopes can achieve their diffraction limit in the near-infrared. Thus infrared cameras, spectrometers and hybrid instruments that measure spatial and spectral information simultaneously are now commanding the greatest attention on telescopes from 6.5 to 10 m in effective aperture. Scientific applications of these new infrared instruments span everything from the search for nearby solar systems to the orbital motions of stars about the massive black hole at the center of the Milky Way, and studies of the first galaxies to form in the high redshift Universe. Background, principles and applications of infrared array detectors to astronomy and astrophysics will be discussed with particular emphasis on work at the W.M. Keck 10-m telescope on Mauna Kea, Hawaii.

Sustainable Astronomy

Blaha, C.; Goetz, J.; Johnson, T.

2011-09-01

Through our International Year of Astronomy outreach effort, we established a sustainable astronomy program and curriculum in the Northfield, Minnesota community. Carleton College offers monthly open houses at Goodsell Observatory and donated its recently "retire" observing equipment to local schools. While public evenings continue to be popular, the donated equipment was underutilized due to a lack of trained student observing assistants. With sponsorship from NASA's IYA Student Ambassador program, the sustainable astronomy project began in 2009 to generate greater interest in astronomy and train middle school and high school students as observing assistants. Carleton physics majors developed curricular materials and instituted regular outreach programs for grades 6-12. The Northfield High School Astronomy Club was created, and Carleton undergraduates taught high school students how to use telescopes and do CCD imaging. During the summer of 2009, Carleton students began the Young Astronomers Summer Experience (YASE) program for middle school students and offered a two-week, astronomy-rich observing and imaging experience at Goodsell Observatory. In concert with NASA's Summer of Innovation initiative, the YASE program was offered again in 2010 and engaged a new group of local middle school students in hands-on scientific experiments and observing opportunities. Members of the high school astronomy club now volunteer as observing assistants in the community and graduates of the YASE programs are eager to continue observing as members of a public service astronomy club when they enter the Northfield High School. These projects are training future scientists and will sustain the public's interest in astronomy long after the end of IYA 2009.

Twenty Years of Precise Radial Velocities at Keck and Lick Observatories

NASA Astrophysics Data System (ADS)

Wright, J. T.

2015-10-01

The precise radial velocity survey at Keck Observatory began over 20 years ago. Its survey of thousands of stars now has the time baseline to be sensitive to planets with decade-long orbits, including Jupiter analogs. I present several newly-finished orbital solutions for long-period giant planets. Although hot Jupiters are generally ``lonely'' (i.e. they are not part of multiplanet systems), those that are not appear to often have giant companions at 5 AU or beyond. I present two of the highest period-ratios among planets in a two-planet system, and some of the longest orbital periods ever measured for exoplanets. In many cases, combining Keck radial velocities from those from other long-term surveys at Lick Observatory, McDonald Observatory, HARPS, and, of course, OHP spectrographs, produces superior orbital fits, constraining both period and eccentricity better than could be possible with any single set alone. Stellar magnetic activity cycles can masquerade as long-period planets. In most cases this effect is very small, but a loud minority of stars, including, apparently, HD 154345, show very strong RV-activity correlations.

2013-04-01

This year we implemented Teach Astronomy as a free online resource to be used as a teaching tool for non-science major astronomy courses and for a general audience interested in the subject. The comprehensive astronomy content of the website includes: an introductory text book, encyclopedia articles, images, two to three minute topical video clips, podcasts, and news articles. Teach Astronomy utilizes a novel technology to cluster, display, and navigate search results, called a Wikimap. We will present an overview of how Teach Astronomy works and how instructors can use it as an effective teaching tool in the classroom. Additionally, we will gather feedback from science instructors on how to improve the features and functionality of the website, as well as develop new assignment ideas using Teach Astronomy.

High-contrast imaging of HD 163296 with the Keck/NIRC2 L΄-band vortex coronograph

2018-06-01

We present observations of the nearby (D˜100 pc) Herbig star HD 163296 taken with the vortex coronograph at Keck/NIRC2 in the L' band (3.7 μm), to search for planetary mass companions in the ringed disc surrounding this pre-main sequence star. The images reveal an arc-like region of scattered light from the disc surface layers that is likely associated with the first bright ring detected with ALMA in the λ=1.3mm dust continuum at ˜65 au. We also detect a point-like source at ˜0{^''.}5 projected separation in the North-East direction, close to the inner edge of the second gap in the millimetre images. Comparing the point source photometry with the atmospheric emission models of non-accreting giant planets, we obtain a mass of 6-7 MJ for a putative protoplanet, assuming a system age of 5 Myr. Based on the contrast at a 95% level of completeness calculated on the emission-free regions of our images, we set upper limits for the masses of giant planets of 8-15 MJ, 4.5-6.5 MJ and 2.5-4.0 MJ at the locations of the first, second and third gap in the millimetre dust continuum, respectively. Further deep, high resolution thermal IR imaging of the HD 163296 system are warranted, to confirm the presence and nature of the point source and to better understand the structure of the dust disc.

Astronomy Communication

NASA Astrophysics Data System (ADS)

Heck, A.; Madsen, C.

2003-07-01

Astronomers communicate all the time, with colleagues of course, but also with managers and administrators, with decision makers and takers, with social representatives, with the news media, and with the society at large. Education is naturally part of the process. Astronomy communication must take into account several specificities: the astronomy community is rather compact and well organized world-wide; astronomy has penetrated the general public remarkably well with an extensive network of associations and organizations of aficionados all over the world. Also, as a result of the huge amount of data accumulated and by necessity for their extensive international collaborations, astronomers have pioneered the development of distributed resources, electronic communications and networks coupled to advanced methodologies and technologies, often much before they become of common world-wide usage. This book is filling up a gap in the astronomy-related literature by providing a set of chapters not only of direct interest to astronomy communication, but also well beyond it. The experts contributing to this book have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy nor in communication techniques while providing specific detailed information, as well as plenty of pointers and bibliographic elements. This book will be very useful for researchers, teachers, editors, publishers, librarians, computer scientists, sociologists of science, research planners and strategists, project managers, public-relations officers, plus those in charge of astronomy-related organizations, as well as for students aiming at a career in astronomy or related space science.

Astronomy and Politics

NASA Astrophysics Data System (ADS)

Steele, John M.

The relationship between astronomy and politics is a complex but important part of understanding the practice of astronomy throughout history. This chapter explores some of the ways that astronomy, astrology, and politics have interacted, placing particular focus on the way that astronomy and astrology have been used for political purposes by both people in power and people who wish to influence a ruler's policy. Also discussed are the effects that politics has had on the development of astronomy and, in particular, upon the recording and preservation of astronomical knowledge.

Here we combine Hα emission from our ZFIRE survey (Nanayakkara+ 2016, J/ApJ/828/21) with galaxy properties from the ZFOURGE survey (Straatman+ 2016, J/ApJ/830/51) and IR luminosities from Spitzer to track how galaxies grow at z~2. ZFIRE is a near-IR spectroscopic survey with MOSFIRE on Keck I where targets are selected from ZFOURGE, an imaging survey that combines deep near-IR observations taken with the FourStar Imager at the Magellan Observatory with public multi-wavelength observations, e.g., Hubble Space Telescope (HST) imaging from CANDELS (Grogin+ 2011ApJS..197...35G). The Keck/MOSFIRE spectroscopy was obtained on observing runs in 2013 December and 2014 February. A total of eight slit masks were observed in the K-band (1.93-2.38um). We also observed two masks in the H-band covering 1.46-1.81um. (1 data file).

Philippine Astronomy Convention 2009 Abstract: Program Offerings in Astronomy in the Philippines

NASA Astrophysics Data System (ADS)

Torres, J. R. F.

2009-03-01

The formal academic programs in Astronomy of the Rizal Technological University are the first such programs in the Philippines. The Master of Science in Astronomy program is envisioned to provide the student with a wide range of knowledge in many areas of Astronomy, leaning towards the descriptive aspects of knowledge. The student will choose the field or research most suitable to his or her interests. Three of these researches done while enrolled in the program, and even researches completed before the student actually enrolled in the program, may be considered as his or her thesis. The program suits professionals in all persuasions who wish to study Astronomy either for professional advancement or plainly for the love of the science or for intellectual satisfaction. Non-science majors can enroll. In 2008, the RTU Graduate School decided to ladderize the MS program and the Graduate Diploma in Astronomy was designed. This program is suited for science educators, astronomy lecturers and entrepreneurs, members of astronomical societies, and plain astronomy enthusiasts who like to gain in-depth knowledge in the most important aspects of astronomy. A bachelor's degree in any field is required. The program can be finished in two semesters and one summer. If the student opts to continue in the MS in Astronomy program, all the courses he or she has earned in the Diploma will be credited. The Bachelor of Science in Astronomy Technology is an intensive baccalaureate degree program designed to prepare students to become future research scientists and technologists in the field of Astronomy. The BS in Astronomy Technology is a cross-fertilized program, integrating interrelated sciences, such as engineering, geology, remote sensing, physics, atmospheric and environmental science, biology and biochemistry, and even philosophy and entrepreneurship into the study. Thus, the B.S. in Astronomy Technology program gives the student excellent job opportunities in many fields.

Introducing Astronomy Related Research into Non-Astronomy Courses

NASA Astrophysics Data System (ADS)

Walker, Douglas

The concern over the insufficient number of students choosing to enter the science and engineering fields has been discussed and documented for years. While historically addressed at the national level, many states are now recognizing that the lack of a highly-skilled technical workforce within their states' borders has a significant effect on their economic health. Astronomy, as a science field, is no exception. Articles appear periodically in the most popular astronomy magazines asking the question, "Where are the young astronomers?" Astronomy courses at the community college level are normally restricted to introductory astronomy I and II level classes that introduce the student to the basics of the night sky and astronomy. The vast majority of these courses is geared toward the non-science major and is considered by many students to be easy and watered down courses in comparison to typical physics and related science courses. A majority of students who enroll in these classes are not considering majors in science or astronomy since they believe that science is "boring and won't produce any type of career for them." Is there any way to attract students? This paper discusses an approach being undertaken at the Estrella Mountain Community College to introduce students in selected mathematics courses to aspects of astronomy related research to demonstrate that science is anything but boring. Basic statistical techniques and understanding of geometry are applied to a large virgin data set containing the magnitudes and phase characteristics of sets of variable stars. The students' work consisted of developing and presenting a project that explored analyzing selected aspects of the variable star data set. The description of the data set, the approach the students took for research projects, and results from a survey conducted at semester's end to determine if student's interest and appreciation of astronomy was affected are presented. Using the data set provided, the

Astronomy in Mozambique

We present the state of Astronomy in Mozambique and how it has evolved since 2009 following the International Year of Astronomy. Activities have been lead by staff at University Eduardo Mondlane and several outreach activities have also flourished. In 2010 the University introduced its first astronomy module, Introduction to Astronomy and Astrophysics, for the second year students in the Department of Physics. The course has now produced the first students who will be graduating in late 2012 with some astronomy content. Some of these students will now be looking for further studies and those who have been keen in astronomy have been recommended to pursue this as a career. At the university level we have also discussed on the possibility to introduce a whole astronomy course by 2016 which falls well within the HCD that the university is now investing in. With the announcement that the SKA will be split between South Africa with its partner countries (including Mozambique), and Australia we have been working closely with the Ministry of Science and Technology to make astronomy a priority on its agenda. In this respect, an old telecommunications antenna is being converted by the South Africa SKA Project Office, and donated to Mozambique for educational purposes. It will be situated in Maluana, Mozambique.

Armenian Cultural Astronomy

NASA Astrophysics Data System (ADS)

Farmanyan, S. V.; Mickaelian, A. M.

2015-07-01

Cultural Astronomy is the reflection of sky events in various fields of nations' culture. In foreign literature this field is also called "Astronomy in Culture" or "Astronomy and Culture". Cultural astronomy is the set of interdisciplinary fields studying the astronomical systems of current or ancient societies and cultures. It is manifested in Religion, Mythology, Folklore, Poetry, Art, Linguistics and other fields. In recent years, considerable attention has been paid to this sphere, particularly international organizations were established, conferences are held and journals are published. Armenia is also rich in cultural astronomy. The present paper focuses on Armenian archaeoastronomy and cultural astronomy, including many creations related to astronomical knowledge; calendars, rock art, mythology, etc. On the other hand, this subject is rather poorly developed in Armenia; there are only individual studies on various related issues (especially many studies related to Anania Shirakatsi) but not coordinated actions to manage this important field of investigation.

Astronomy in Asia

Soonthornthum, B.

2006-08-01

Astronomy in Asia has continuously developed. Local wisdom in many Asian countries reflects their interest in astronomy since the historical period. However, the astronomical development in each country is different which depends on their cultures, politics and economics. Astronomy in some Asian developing countries such as China and India are well-developed while some other countries especially in south-east Asia, with some supports such as telescopes, trainings, experts etc. from some developed countries, are trying to promote relevant research in astronomy as well as use astronomy as a tool to promote scientific awareness and understanding for the public. Recently, a new national research institute in astronomy with a 2.4-meter reflecting telescope has been established in Thailand. One of the major objectives of this research-emphasis institute would aim at a collaborative network among south-east Asian countries so as to be able to contribute new knowledge and research to the astronomical community.

Journey of Ethiopia Astronomy

Ancient astronomy had contributed away for the modern development of astronomy. The history of astronomy development in Ethiopian was liked with different beliefs and culture of the society. The Ethiopians were the first who invented the science of stars, and gave names to the planets, not at random and without meaning, but descriptive of the qualities which they conceived them to possess; and it was from them that this art passed, still in an imperfect state, to the Egyptians. Even though, Ethiopian’s contributions for astronomy in the world were immense but the journey of modern astronomy is still in the infant stage. The modern astronomy and space program in Ethiopia was started in 2004 in well organized form from three individuals to the public. In the past eleven years of journey of astronomy development in Ethiopia was the most challenging from national to international level. After strong struggle of a few committed individuals for the past eleven years the development of astronomy is completely changed from dark age to bright age. This paper will try to address the details of journey of astronomy in Ethiopia.

2001-12-01

The Astronomy Workshop (http://janus.astro.umd.edu) is an interactive online astronomy resource developed, and maintained at the University of Maryland, for use by students, educators and the general public. The Astronomy Workshop has been extensively tested and used successfully at many different levels, including High School and Junior High School science classes, University introductory astronomy courses, and University intermediate and advanced astronomy courses. Some topics currently covered in the Astronomy Workshop are: Animated Orbits of Planets and Moons: The orbits of the nine planets and 91 known planetary satellites are shown in animated, to-scale drawings. The orbiting bodies move at their correct relative speeds about their parent, which is rendered as an attractive, to-scale gif image. Solar System Collisions: This most popular of our applications shows what happens when an asteroid or comet with user-defined size and speed impacts a given planet. The program calculates many effects, including the country impacted (if Earth is the target), energy of the explosion, crater size, magnitude of the planetquake generated. It also displays a relevant image (e.g. terrestrial crater, lunar crater, etc.). Planetary and Satellite Data Calculators: These tools allow the user to easily calculate physical data for all of the planets or satellites simultaneously, making comparison very easy. Orbital Simulations: These tools allow the student to investigate different aspects of the three-body problem of celestial mechanics.

The Korean Astronomical Society initiated the Korea Astronomy Olympiad (KAO) in 2001 and also began to participate in the international astronomy olympiad in 2002, as a means to promote astronomy among Korean high school students. To find out how successful such endeavor has been, first how partipating students regard astronomy as their career choice has been investigated. Of the students who have taken part in the international astronomy olympiads and then have entered a college afterwards in the period 2002-2014, more than 50% have chosen astronomy, physics, or earth science as their college major. In addition, when the future career choices of the KAO applicants were examined through their school records, astronomy and space science were chosen to be 44% in 2014, a significant increase from 25% in 2010. Secondly, the astronomical content of the regular Korean high school curriculum has been compared with the syllabus of international astronomy olympiads, to see how students can enhance their astronomical understanding through participating in astronomy olympiads, which would in turn contribute to their possible future career in astronomy.

We present the Team Keck Redshift Survey 2 (TKRS2), a spectroscopic survey of 97 distant galaxies exploiting the capabilities of the Multi-Object Spectrometer For Infra-Red Exploration (MOSFIRE) on the Keck I telescope at the W. M. Keck Observatory. MOSFIRE features a 2048*2048 pixel HAWAII-2RG HgCdTe detector array from Teledyne Imaging Sensors that couples high quantum efficiency with low noise and low dark current. The operating range of 0.97-2.41μm covers the YJHK infrared passbands, with wavelength coverage of 0.97-1.12μm in Y, 1.15-1.35μm in J, 1.47-1.80μm in H, and 1.95-2.40μm in K. The resolving power for the default slit width of 0.7" is R=3380 in Y, 3310 in J, 3660 in H, and 3620 in K, corresponding to full-width-half-maximum (FWHM) spectral resolutions of 3.1Å in Y, 3.7Å in J, 4.4Å in H, and 6.0Å in K. Our survey targets the south-central region of the GOODS-North survey field (Giavalisco et al. 2004, cat. II/261). We employed MOSFIRE to acquire spectra in the GOODS-North field over a series of partial nights spanning the period from 2012 November to 2013 May. We present the results of our survey in Table3 and on the website (http://arcoiris.ucsc.edu/TKRS2/) devoted to the survey. (1 data file).

Astronomy in Indian Schools

NASA Astrophysics Data System (ADS)

Bhatia, V. B.

Tradition of astronomy in India goes back to ancient times. Many festivals and rituals are associated with astronomical phenomena. Indian children start learning rudiments of astronomy from primary classes. But primary teachers are not equipped to handle this subject so not much learning actually takes place. The first serious interface with astronomy occurs when children reach class X when they are 15 years old. Till last year astronomy was there in class XII also but it has now been dropped. This is a serious setback for the study of astronomy. In class X astronomy forms part of general science. Since children at this stage are not proficient in physics and mathematics the subject remains descriptive though there are useful activities for children to do. However the teachers are not equipped to handle this subject and there is no help in the form of visual material. So the subject remains neglected. The Indian astronomical community can help by training teachers and providing visual material. It must also urge authorities to reintroduce astronomy in class XII if astronomy is to flourish in India. Moreover India needs to network with developing countries share experiences with them and evolve a strategy that promotes astronomy.

The Keck Geology Consortium, with support from the National Science Foundation (REU Program) and ExxonMobil, is a collaborative effort by 18 colleges to improve geoscience education through high-quality research experiences. Since its inception in 1987 more than 1350 undergraduate students and 145 faculty have been involved in 189 yearlong research projects. This non-traditional REU model offers exceptional opportunities for students to address research questions at a deep level, to learn and utilize sophisticated analytical methods, and to engage in authentic collaborative research that culminates in an undergraduate research symposium and published abstracts volume. The large numbers of student and faculty participants in Keck projects also affords a unique opportunity to study the impacts of program design on undergraduate research experiences in the geosciences. Students who participate in Keck projects generally report significant gains in personal and professional dimensions, as well as in clarification of educational and career goals. Survey data from student participants, project directors, and campus advisors identify mentoring as one of the most critical and challenging elements of successful undergraduate research experiences. Additional challenges arise from the distributed nature of Keck projects (i.e., participants, project directors, advisors, and other collaborators are at different institutions) and across the span of yearlong projects. In an endeavor to improve student learning about the nature and process of science, and to make mentoring practices more intentional, the Consortium has developed workshops and materials to support both project directors and campus research advisors (e.g., best practices for mentoring, teaching ethical professional conduct, benchmarks for progress, activities to support students during research process). The Consortium continues to evolve its practices to better support students from underrepresented groups.

Lick Observatory, California, and 20th Century Leadership in Optical Astronomy

NASA Astrophysics Data System (ADS)

Miller, Joseph

2008-04-01

With the establishment of the Lick Observatory on Mt. Hamilton in California in 1888 it was immediately established that an observatory located on a relatively high site far from city lights was a far superior location for optical astronomy than the previously common city locations. A few years after its beginning, astronomers at Lick convincingly demonstrated the clear advantage of the reflecting telescope for astrophysical research. Not only was a reflector achromatic over all wavelengths, but it could be made with a small focal ratio that provided high photographic speed. Furthermore, since light did not pass through the optic and it could be supported from behind, it could easily be made in large sizes. Over the first half of the 20^th century the establishment of the Mt. Wilson and Palomar Observatories expanded California's dominance in optical astronomy. Also with the new larger telescopes came major progress in the in design of focal plane instrumentation that allowed these telescopes to be superb tools for astrophysical research. The California observatories of the 20th century were largely independent of Federal funding for operations. Their facilities were were maintained and mostly used by their permanent staffs. This led to a style of doing forefront research that was highly effective, as both long-term survey-type programs and more speculative investigations with less-clear payoffs at the outset could be supported. Also the, the close connection of the scientists doing the research to the development of the telescopes and instruments they used for their research conferred advantages. At present, this style of doing astronomical observational research is a relatively small fraction of all this kind of research. At the end of the 20^th century the California pioneering advancement in ground-based optical astronomy was repeated with the creation of the Keck Observatory. A joint project of the University of California and the California Institute of

The authors report on observations taken during engineering science validation time using the new adaptive optics system at the 10-m Keck II Telescope. They observe Neptune and Titan at near-infrared wavelengths. These objects are ideal for adaptive optics imaging because they are bright and small, yet have many diffraction-limited resolution elements across their disks. In addition Neptune and Titan have prominent physical features, some of which change markedly with time. They have observed infrared-bright storms on Neptune, and very low-albedo surface regions on Titan, Saturn's largest moon, Spatial resolution on Neptune and Titan was 0.05-0.06 and 0.04-0.05 arc sec, respectively.

Spatially Resolved Emission of a z~3 Damped Lyman Alpha Galaxy with Keck/OSIRIS IFU

NASA Astrophysics Data System (ADS)

Christenson, Holly; Jorgenson, Regina

2017-01-01

The damped Lyman alpha (DLA) class of galaxies contains most of the neutral hydrogen gas over cosmic time. Few DLAs have been detected directly, which limits our knowledge of fundamental properties like size and mass. We present Keck/OSIRIS infrared integral field spectroscopy (IFU) observations of a DLA that was first detected in absorption toward a background quasar. Our observations use the Keck Laser Guide Star Adaptive Optics system to reduce the point-spread function of the quasar, making it possible to spatially resolve the DLA emission. We map this emission in O[III] 5007 Å. At redshift z~3, this DLA represents one of the highest redshift DLAs mapped with IFU spectroscopy. We present measurements of the star formation rate, metallicity, and gas mass of the galaxy.This project was supported in part by the NSF REU grant AST-1358980 and by the Nantucket Maria Mitchell Association.

The California-Arizona Minority Partnership for Astronomy Research and Education (CAMPARE) is an NSF-funded partnership between the Astronomy Program at Cal Poly Pomona and the University of Arizona Steward Observatory designed to promote participation of underrepresented minorities, including women, in astronomy research and education. By means of this program, Cal Poly Pomona undergraduates that are either Physics majors or minors are qualified to participate in the program alongside graduate students from the University of Arizona as a camp counselor at the University of Arizona's Astronomy Camp, one of the elite astronomy programs worldwide. Students that participate in the CAMPARE program are granted an opportunity to work in a hands-on environment by teaching astronomy to students from all over the world in a highly structured environment. The CAMPARE student selected for this program in Summer 2011 worked under the supervision of Dr. Don McCarthy, professor at the University of Arizona and Astronomy Camp director for over 20 years, learning to lead a group of students through daily activities and ensure that the students are learning to their maximum potential. Through this experience, the CAMPARE student learned to capture students’ interest in astronomy and was introduced to real life teaching, which has helped prepare him for future experiences to come. We acknowledge the NSF for funding under Award No. AST-0847170, a PAARE Grant for the Calfornia-Arizona Minority Partnership for Astronomy Research and Education (CAMPARE).

The Infrared Processing and Analysis Center (IPAC) and the W. M. Keck Observatory (WMKO) are collaborating to build an archive for the twin 10-m Keck Telescopes, located near the summit of Mauna Kea. The Keck Observatory Archive (KOA) takes advantage of IPAC's long experience with managing and archiving large and complex data sets from active missions and serving them to the community; and of the Observatory's knowledge of the operation of its sophisticated instrumentation and the organization of the data products. By the end of 2013, KOA will contain data from all eight active observatory instruments, with an anticipated volume of 28 TB. The data include raw science and observations, quick look products, weather information, and, for some instruments, reduced and calibrated products. The goal of including data from all instruments is the cumulation of a rapid expansion of the archive's holdings, and already data from four new instruments have been added since October 2012. One more active instrument, the integral field spectrograph OSIRIS, is scheduled for ingestion in December 2013. After preparation for ingestion into the archive, the data are transmitted electronically from WMKO to IPAC for curation in the physical archive. This process includes validation of the science and content of the data and verification that data were not corrupted in transmission. The archived data include both newly-acquired observations and all previously acquired observations. The older data extends back to the date of instrument commissioning; for some instruments, such as HIRES, these data can extend as far back as 1994. KOA will continue to ingest all newly obtained observations, at an anticipated volume of 4 TB per year, and plans to ingest data from two decommissioned instruments. Access to these data is governed by a data use policy that guarantees Principal Investigators (PI) exclusive access to their data for at least 18 months, and allows for extensions as granted by

In this paper, we present results from our analysis of Chandra X-Ray Observatory, W. M. Keck Observatory, and Karl G. Jansky Very Large Array (VLA) images of the Crab Nebula that were contemporaneous with the γ-ray flare of 2011 April. Despite hints in the X-ray data, we find no evidence for statistically significant variations that pinpoint the specific location of the flares within the Nebula. The Keck observations extend this conclusion to the "inner knot," i.e., the feature within an arcsecond of the pulsar. The VLA observations support this conclusion. Lastly, we also discuss theoretical implications of the γ-ray flaresmore » and suggest that the most dramatic γ-ray flares are due to radiation-reaction-limited synchrotron emission associated with sudden, dissipative changes in the current system sustained by the central pulsar.« less

Indian Astronomy: the missing link in Eurocentric history of Astronomy

NASA Astrophysics Data System (ADS)

Haque, Shirin; Sharma, Deva

2016-06-01

A comprehensive history of Astronomy should show in reasonable chronological order, the contributions from wherever they arise in the world, once they are reliably documented. However, the authors note that consistently, the extremely rich contributions from Ancient Indian scholars like Aryabatha and Bhramagupta are omitted in Eurocentric education and syllabi. It is speculated whether religious underpinnings could have been responsible for its suppression in the past. An appeal is made to represent the history of Astronomy in Eurocentric versions, to be inclusive of Indian Astronomy as accurately and completely as possible in science education.

Joseph Henry and Astronomy

NASA Astrophysics Data System (ADS)

Rothenberg, Marc

2016-01-01

Joseph Henry (1797-1878) is best known for his work in electromagnetism and as the first secretary of the Smithsonian Institution. But he was also a pioneer solar physicist, an early advocate of US participation in astrophysics, and a facilitator of international cooperation in astronomy. This paper will briefly trace his role in the development of the US astronomical community from the time he taught astronomy at Princeton in the 1830s through his death, focusing on failed efforts to persuade US astronomers and patrons of astronomy that the best path for US astronomy should be astrophysics. He thought that the US could make a more significant contribution to astronomy science by striking out on a less travelled path rather than competing with the established European observatories.

2017-01-01

The National Astronomical Research Institute of Thailand (NARIT) have launched the program "Advance Teacher Training Workshop" that aims to introduce both the students and astronomy teacher alike to the nature of critical thinking in science via hands on experience in astronomy projects. Students and accompanying teachers are participated in 5 days workshop in which each of them must select an individual astronomy research project. The project is then carried out on their own for the next 6 months, after which their works are presented in a conference. Progress is monitored and extra aid is delivered as needed via the use of social media. Over a hundred projects have been completed under this program. Follow up study have suggests that this workshop has shown to be quite successful at improving critical thinking skills in participants. As the program became more popular, other schools began to follow. To support the growing interest, we have also launched the "Thai Astronomical Society: student session", a highschool astronomy conference for anyone who participated or interested in astronomy related projects. Via these stages we are able to secure a permanent foothold in Thai astronomy education and inspire new generations to participate in astronomy projects.

Astronomy Landscape in Africa

The vision for astronomy in Africa is embedded in the African Space Policy of the African Union in early 2014. The vision is about positioning Africa as an emerging hub for astronomy sciences and facilities. Africa recognized the need to take advantage of its natural resource, the geographical advantage of the clear southern skies and pristine sites for astronomy. The Pan African University (PAU) initiative also presents an opportunity as a post-graduate training and research network of university nodes in five regions of Africa and supported by the African Union. The Southern African node based in South Africa concentrates on space sciences which also includes astronomy. The PAU aims to provide the opportunity for advanced graduate training and postgraduate research to high-performing African students. Objectives also include promoting mobility of students and teachers and harmonizing programs and degrees.A number of astronomy initiatives have burgeoned in the Southern African region and these include the Southern Africa Largest Optical Telescope (SALT), HESS (High Energy Stereoscopic System), the SKA (Square Kilometre Array) and the AVN (African Very Long Baseline Interferometer Network). There is a growing appetite for astronomy sciences in Africa. In East Africa, the astronomy community is well organized and is growing - the East African Astronomical society (EAAS) held its successful fourth annual conference since 2010 on 30 June to 04 July 2014 at the University of Rwanda. Centred around the 'Role of Astronomy in Socio-Economic Transformation,' this conference aimed at strengthening capacity building in Astronomy, Astrophysics and Space Science in general, while providing a forum for astronomers from the region to train young and upcoming scientists.

Imagine you are a grad student, at your first conference, and a prominent senior scientist shows interest in your work, and he makes things get way too personal? What would you do? Would you report it? Or would you decide, after a few other instances of harassment, that maybe you shouldn't pursue astronomy? Harassment is under-reported, the policies can be difficult to understand or hard to find, and it can be very intimidating as a young scientist to report it to the proper individuals. The Astronomy Allies Program is designed to help you with these sorts of problems. We are a group of volunteers that will help by doing the following: provide safe walks home during the conference, someone to talk to confidentially, as an intervener, as a resource to report harassment. The Allies are a diverse group of scientists committed to acting as mentors, advocates, and liaisons. The Winter 2015 AAS meeting was the first meeting that had Astronomy Allies, and Astronomy Allies provided a website for information, as well as a twitter, email, and phone number for anyone who needs our help or would like more information. We posted about the Astronomy Allies on the Women In Astronomy blog, and this program resonates with many people: either they want to help, or they have experienced harassment in the past and don't want to see it in the future. Harassment may not happen to most conference participants, but it's wrong, it's against the AAS anti-harassment policy ( http://aas.org/policies/anti-harassment-policy ), it can be very damaging, and if it happens to even one person, that is unacceptable. We intend to improve the culture at conferences to make it so that harassers feel they can't get away with their unprofessional behavior.

Initial Performance of the Keck AO Wavefront Controller System

DOE Office of Scientific and Technical Information (OSTI.GOV)

Johansson, E M; Acton, D S; An, J R

2001-03-01

The wavefront controller for the Keck Observatory AO system consists of two separate real-time control loops: a tip-tilt control loop to remove tilt from the incoming wavefront, and a deformable mirror control loop to remove higher-order aberrations. In this paper, we describe these control loops and analyze their performance using diagnostic data acquired during the integration and testing of the AO system on the telescope. Disturbance rejection curves for the controllers are calculated from the experimental data and compared to theory. The residual wavefront errors due to control loop bandwidth are also calculated from the data, and possible improvements tomore » the controller performance are discussed.« less

Astronomy from the chair - the application of the Internet in promoting of Astronomy

NASA Astrophysics Data System (ADS)

Tomic, Zoran

2014-05-01

Internet and modern communication technologies are an indispensable part of modern life. The use of the Internet makes it possible to enhance the education and expand opportunities for acquiring new knowledge. One example is Astronomy, where today thanks to the Internet, we can control telescopes that are distant from us and listen to lectures from Universities in other countries. "Astronomy from the chair" is the name for a concept where amateur astronomers can deal with astronomy from their homes using the Internet. The concept can be divided into four sections depending on the content being offered: Robotic Observatory, Virtual Observatory, Online astronomy broadcasting and Online courses. Robotic observatory is defined as an astronomical instrument and detection system that enables efficient observation without the need of a person's physical intervention. Virtual Observatory is defined as a collection of databases and software tools that use the Internet as a platform for scientific research. Online astronomy broadcasting is part of concept "Astronomy from the chair" which gives users the opportunity to get directly involved in astronomical observation organized by an amateur astronomer from somewhere in the world. Online courses are groups of sites and organizations that provide the opportunity to amateur astronomers to attend lectures, save and watch video materials from lectures, do homework, communicate with other seminar participants and in that way become familiar with the various areas of Astronomy. This paper discusses a new concept that describes how the Internet can be applied in modern education. In this paper will be described projects that allows a large number of astronomy lovers to do their own research without the need to own a large and expensive set of astronomical equipment (Virtual Telescope from Italy, Observatory "Night Hawk" from Serbia and project "Astronomy from an armchair" at Faculty of Sciences and Mathematics in Nis), to help

Teaching Astronomy with Technology

Austin, Carmen; Impey, Chris David; Wenger, Matthew

2015-01-01

Students today are expected to have access to computers and the Internet. Students young and old, in school and out of school, are interested in learning about astronomy, and have computers to use for this. Teach Astronomy is a website with a comprehensive digital astronomy textbook freely available to students and educators. In addition to the textbook, there are astronomy Wikipedia articles, image archives from Astronomy Picture of the Day and AstroPix, and video lectures covering all topics of astronomy. Teach Astronomy has a unique search tool called the wikimap that can be used to search through all of the resources on the site. Astronomy: State of the Art (ASOTA) is a massive, open, online course (MOOC). Over 18,000 students have enrolled over the past year and half. This MOOC has been presented in various forms. First, only to students on the web, with content released weekly on host site Udemy. Then to university students who met formally in the classroom for educational activities, but were also expected to watch lectures online on their own time. Presently, it is available online for students to go at their own pace. In the future it will be available in an extended format on a new host site, Coursera. ASOTA instructors use social media to interact with students. Students ask questions via the course host site, Udemy. Live question and answer sessions are conducted using Google Hangouts on Air, and interesting and relevant astronomy news, or supplementary educational content is shared via the ASOTA Facebook page. Teaching on the Internet may seem impersonal and impractical, but by learning to use all of these tools, instructors have the ability to interact with students, and keep them engaged.

Learning radio astronomy by doing radio astronomy

Vaquerizo Gallego, J. A.

2011-11-01

PARTNeR (Proyecto Académico con el Radio Telescopio de NASA en Robledo, Academic Project with the NASA Radio Telescope at Robledo) is an educational program that allows high school and undergraduate students to control a 34 meter radio telescope and conduct radio astronomical observations via the internet. High-school teachers who join the project take a course to learn about the science of radio astronomy and how to use the antenna as an educational resource. Also, teachers are provided with learning activities they can do with their students and focused on the classroom implementation of the project within an interdisciplinary framework. PARTNeR provides students with firsthand experience in radio astronomy science. Thus, remote radio astronomical observations allow students to learn with a first rate scientific equipment the basics of radio astronomy research, aiming to arouse scientific careers and positive attitudes toward science. In this contribution we show the current observational programs and some recent results.

Conceptual Astronomy Knowledge among Amateur Astronomers

NASA Astrophysics Data System (ADS)

Berendsen, Margaret L.

Amateur astronomers regularly serve as informal astronomy educators for their communities. This research inquires into the level of knowledge of basic astronomy concepts among amateur astronomers and examines factors related to amateur astronomy that affect that knowledge. Using the concept questions from the Astronomy Diagnostic Test Version 2, an online survey was developed as an assessment. In particular, astronomy club members with at least some college-level astronomy education score substantially higher on the assessment (mean score: 85) than do college undergraduates after taking their first astronomy course (mean score: 47). Astronomy club members scored up to 17% higher than unaffiliated amateurs, an indication that regular contact with like-minded hobbyists improves basic knowledge. Proportionally more astronomy club members report doing outreach than do unaffiliated amateurs (87% vs. 46%). It appears that those who are likely to be more knowledgeable are also those doing more outreach.

Hubble and Keck team up to find farthest known galaxy in the Universe

NASA Astrophysics Data System (ADS)

2004-02-01

most distant source currently known. However, long exposures in the optical and infrared taken with spectrographs on the 10-meter Keck telescopes suggests that the object has a redshift towards the upper end of this range, around redshift 7. Redshift is a measure of how much the wavelengths of light are shifted to longer wavelengths. The greater the shift in wavelength toward the redder regions of the spectrum, the more distant the object is. "The galaxy we have discovered is extremely faint, and verifying its distance has been an extraordinarily challenging adventure," said Dr. Kneib. "Without the 25 x magnification afforded by the foreground cluster, this early object could simply not have been identified or studied in any detail at all with the present telescopes available. Even with aid of the cosmic lens, the discovery has only been possible by pushing our current observatories to the limits of their capabilities!" Using the combination of the high resolution of Hubble and the large magnification of the cosmic lens, the astronomers estimate that this object, although very small - only 2,000 light-years across - is forming stars extremely actively. However, two intriguing properties of the new source are the apparent lack of the typically bright hydrogen emission line and its intense ultraviolet light which is much stronger than that seen in star-forming galaxies closer by. "The properties of this distant source are very exciting because, if verified by further study, they could represent the hallmark of a truly young stellar system that ended the Dark Ages" added Dr. Richard Ellis, Steele Professor of Astronomy at Caltech, and a co-author in the article. The team is encouraged by the success of their technique and plans to continue the search for more examples by looking through other cosmic lenses in the sky. Hubble's exceptional resolution makes it ideally suited for such searches. "Estimating the abundance and characteristic properties of sources at early times

Astronomy Popularization via Sci-fi Movies

NASA Astrophysics Data System (ADS)

Li, Qingkang

2015-08-01

It is astronomers’ duty to let more and more young people know a bit astronomy and be interested in astronomy and appreciate the beauty and great achievements in astronomy. One of the most effective methods to popularize astronomy to young people nowadays might be via enjoying some brilliant sci-fi movies related to astronomy with some guidance from astronomers. Firstly, we will introduce the basic information of our selective course “Appreciation of Sci-fi Movies in Astronomy” for the non-major astronomy students in our University, which is surely unique in China, then we will show its effect on astronomy popularization based on several rounds of teaching.

Polarization Angle Calibration and B-Mode Characterization with the BICEP and Keck Array CMB Telescopes

NASA Astrophysics Data System (ADS)

Bullock, Eric

Since its discovery in 1964, the Cosmic Microwave Background (CMB) has led to widespread acceptance of the Big Bang cosmological paradigm as an explanation for the evolution of the Universe. However, this paradigm does not explain the origin of the initial conditions, leading to such issues as the "horizon problem" and "flatness problem." In the early 1980's, the inflationary paradigm was introduced as a possible source for the initial conditions. This theory postulates that the Universe underwent a period of exponential expansion within a tiny fraction of a second after the beginning. Such an expansion is predicted to inject a stochastic background of gravitational waves that could imprint a detectable B-mode (curl-like) signal in the polarization of the CMB. It is this signal that the family of telescopes used by the B ICEP1, BICEP2, and Keck Array collaborations were designed to detect. These telescopes are small aperture, on-axis, refracting telescopes. We have used the data from these telescopes, particularly BICEP2 and the Keck Array, to place the tightest constraints, as of March 2016, on the tensor-to-scalar ratio of the CMB of r 0.05 < 0.07. In this dissertation, we provide an overview of the Keck Array telescopes and analysis of the data. We also investigate, as the main focus of this dissertation, a device we call the Dielectric Sheet Calibrator (DSC) that is used to measure the polarization angles of our detectors as projected on the sky. With these measurements, we gain the potential to separate the polarization rotation effects of parity-violating physics, such as cosmic birefringence, from a systematic uncertainty on our detectors' polarization angles. Current calibration techniques for polarization sensitive CMB detectors claim an accuracy of +/-0.5°, which sets a limit for determining the usefulness of the DSC. Through a series of consistency tests on a single Keck Array receiver, we demonstrate a statistical uncertainty on the DSC measurements of

Astronomy and Mathematics Education

NASA Astrophysics Data System (ADS)

Ros, Rosa M.

There are many European countries where Astronomy does not appear as a specific course on the secondary school. In these cases Astronomy content can be introduced by means of other subjects. There are some astronomical topics within the subject of Physics but this talk concerns introducing Astronomy in Mathematics classes. Teaching Astronomy through Mathematics would result in more exposure than through Physics as Mathematics is more prevalent in the curriculum. Generally it is not easy to motivate students in Mathematics but they are motivated to find out more about the universe and Astronomy current events than appears in the media. This situation can be an excellent introduction to several mathematics topics. The teachers in secondary and high school can use this idea in order to present more attractive mathematics courses. In particular some different examples will be offered regarding * Angles and spherical coordinates considering star traces * Logarithms and visual magnitudes * Plane trigonometry related orbital movements * Spherical trigonometry in connection with ecliptic obliquity * Conic curves related to sundial at several latitudes Some students do not enjoy studying Mathematics but they can be attracted by practical situations using Applied Mathematics: Astronomy is always very attractive to teenagers.

Operating a wide-area high-availability collaborative remote observing system for classically-scheduled observations at the W. M. Keck Observatory

NASA Astrophysics Data System (ADS)

2011-03-01

For over a decade, the W. M. Keck Observatory's two 10-meter telescopes have been operated remotely from its Waimea headquarters. Over the last 9 years, WMKO remote observing has expanded to allow observing teams at dedicated sites located across California to observe via the Internet either in collaboration with colleagues in Waimea or entirely from California; this capability was extended to Swinburne University in Melbourne, Australia in 2010 and to Yale University in New Haven, Connecticut in early 2011. All Keck facility science instruments are currently supported. Observers distributed between as many as four sites can collaborate in the interactive operation of each instrument by means of shared VNC desktops and multipoint video and/or telephone conferencing. Automated routers at primary remote observing sites ensure continued connectivity during Internet outages. Each Keck remote observing facility is similarly equipped and configured so observers have the same operating environment. This architecture provides observers the flexibility to conduct observations from the location best suited to their needs and to adapt to last-minute changes. It also enhances the ability of off-site technical staff to provide remote support.

Addressing chronic operational issues at the W. M. Keck Observatory

NASA Astrophysics Data System (ADS)

Nordin, Tom; Matsuda, Richard

2016-07-01

The W. M. Keck Observatory (WMKO) has a good track record at addressing large critical faults which impact observing. Our performance tracking and correcting chronic minor faults has been mixed, yet this class of problems has a significant negative impact on scientific productivity and staff effectiveness. We have taken steps to address this shortcoming. This paper outlines the creation of a program to identify, categorize and rank these chronic operational issues, track them over time, and develop management options for their resolution. The success of the program at identifying these chronic operational issues and the advantages of dedicating observatory resources to this endeavor are presented.

Astronomy in Culture

NASA Astrophysics Data System (ADS)

Stavinschi, M.

2010-07-01

Which is more appropriate? “Astronomy in culture,” or “Astronomy and culture,” or “Culture without astronomy?” These are only few variants, each with its own sense. I guess the last question is the most pertinent. Does culture really exist without astronomy? The existence and evolution of the human civilization answer NO! But what “culture” means? When we are thinking of a culture (the Hellenistic one, for instance), we mean a set of customs, artistic, religious, intellectual manifestations that differentiate one group or society from another. On the other hand, we often use the notion of culture in a different sense: shared beliefs, ways of regarding and doing, which orient more or less consciously the behavior of an individual or a group. An example would be the laic culture. Moreover, the set of knowledge acquired in one or several domains also constitutes a culture, for instance the scientific culture of an individual or a group. Finally, the set of cultures is nothing else but the civilization. Now, if we come back in time into the history of civilization, we find a permanent component, which was never missing and often played a decisive part in its evolution: the Astronomy.

Minoan Astronomy

NASA Astrophysics Data System (ADS)

Blomberg, Mary; Henriksson, Göran

Of the three great cultures of the ancient eastern Mediterranean — the Babylonian, Egyptian, and Minoan — we have considerable knowledge of the astronomy of the first two through their documents (see relevant sections of this Handbook). Very little written material, however, has survived from Minoan Crete, but the evidence of other impressive archaeological discoveries implies that the inhabitants were on a par with their neighbors and had made similar advances in astronomy. In lieu of written sources, we have used the methods of archaeoastronomy to recover as much as possible about Minoan astronomy. In short, these are measuring the orientations of walls and their opposite horizons at a representative selection of monuments, analyzing the measurements statistically, and comparing the results with digital reconstruction of the positions of significant celestial bodies for the time when the walls were built.

Astronomy in Iraq

NASA Astrophysics Data System (ADS)

Alsabti, A. W.

2006-08-01

The history of modern Iraqi astronomy is reviewed. During the early 1970's Iraqi astronomy witnessed significant growth through the introduction of the subject at university level and extensively within the school curriculum. In addition, astronomy was popularised in the media, a large planetarium was built in Baghdad, plus a smaller one in Basra. Late 1970 witnessed the construction of the Iraqi National Observatory at Mount Korek in Iraqi Kurdistan. The core facilities of the Observatory included 3.5-meter and 1.25-meter optical telescopes, and a 30-meter radio telescope for millimetre wavelength astronomy. The Iraqi Astronomical Society was founded and Iraq joined the IAU in 1976. During the regime of Saddam Hussain in the 1980's, the Observatory was attacked by Iranian artillery during the Iraq-Iran war, and then again during the second Gulf war by the US air force. Years of sanctions during the 1990's left Iraq cut off from the rest of the international scientific community. Subscriptions to astronomical journals were halted and travel to conferences abroad was virtually non-existent. Most senior astronomers left the country for one reason or another. Support from expatriate Iraqi astronomers existed (and still exists) however, this is not sufficient. Recent changes in Iraq, and the fall of Saddam's regime, has meant that scientific communication with the outside world has resumed to a limited degree. The Ministry of Higher Education in Baghdad, Baghdad University and the Iraqi National Academy of Science, have all played active roles in re-establishing Iraqi astronomy and re-building the damaged Observatory at Mount Korek. More importantly the University of Sallahudin in Erbil, capital of Iraqi Kurdistan, has taken particular interest in astronomy and the Observatory. Organized visits to the universities, and also to the Observatory, have given us a first-hand assessment of the scale of the damage to the Observatory, as well as the needs of astronomy teaching

We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400  deg^{2} patch of sky centered on RA 0 h, Dec. -57.5°. The combined maps reach a depth of 57 nK deg in Stokes Q and U in a band centered at 150 GHz. Planck has observed the full sky in polarization at seven frequencies from 30 to 353 GHz, but much less deeply in any given region (1.2  μK deg in Q and U at 143 GHz). We detect 150×353 cross-correlation in B modes at high significance. We fit the single- and cross-frequency power spectra at frequencies ≥150  GHz to a lensed-ΛCDM model that includes dust and a possible contribution from inflationary gravitational waves (as parametrized by the tensor-to-scalar ratio r), using a prior on the frequency spectral behavior of polarized dust emission from previous Planck analysis of other regions of the sky. We find strong evidence for dust and no statistically significant evidence for tensor modes. We probe various model variations and extensions, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint. Finally, we present an alternative analysis which is similar to a map-based cleaning of the dust contribution, and show that this gives similar constraints. The final result is expressed as a likelihood curve for r, and yields an upper limit r_{0.05}<0.12 at 95% confidence. Marginalizing over dust and r, lensing B modes are detected at 7.0σ significance.

Astronomy in Everyday Life

NASA Astrophysics Data System (ADS)

Rosenberg, M.; Bladon, G.; Russo, P.; Christensen, L. L.

2014-01-01

For a long time astronomers and other scientists believed that the importance of their work was evident to society. But in these difficult days of financial austerity, even the most obvious benefits of science have to undergo careful scrutiny. So, now more than ever is the time to highlight the importance of astronomy as a field in terms of its contributions to our technology, our mind sets and our lives. Here we will outline both the tangible and intangible reasons why astronomy is an important part of society. Whilst considerable attention will be given to technology and knowledge transfer from astronomy, perhaps the most important contribution outlined is the awareness that astronomy gives us of the vastness of the Universe and our place within it.

How Create an Astronomy Outreach Program to Bring Astronomy to Thousands of People at Outdoor Concerts Astronomy Festivals, or Tourist Sites

NASA Astrophysics Data System (ADS)

Lubowich, Donald

2015-08-01

I describe how to create an astronomy program for thousands of people at outdoor concerts based on my $308,000 NASA-funded Music and Astronomy Under the Stars (MAUS) program (60 events 2009 - 2013), and the Astronomy Festival on the National Mall (AFNM, 10,000 people/yr).MAUS reached 50,000 music lovers at local parks and at the Central Park Jazz, Newport Folk, Ravinia, or Tanglewood Music Festivals with classical, folk, pop/rock, opera, Caribbean, or county-western concerts assisted by astronomy clubs. Yo-Yo-Ma, the Chicago and Boston Symphony Orchestras, Ravi Coltrane, Esperanza Spalding, Phish, Blood Sweat and Tears, Deep Purple, Tony Orlando, and Wilco performed at these events. AFNM was started in 2010 with co-sponsorship by the White House Office of Science and Technology Policy. MAUS and AFMN combine solar, optical, and radio telescope observations; large posters/banners; hands-on activities, imaging with a cell phone mount; citizen science activities; hand-outs; and teacher info packet. Representatives from scientific institutions participated. Tyco Brahe, Johannes Kepler, and Caroline Herschel made guest appearances.MAUS reached underserved groups and attracted large crowds. Young kids participated in this family learning experience-often the first time they looked through a telescope. While < 50% of the participants took part in a science activity in the past year, they found MAUS enjoyable and understandable; learned about astronomy; wanted to learn more; and increased their interest in science (ave. rating 3.6/4). MAUS is effective in promoting science education!Lessons learned: plan early; create partnerships with parks, concert organizers, and astronomy clubs; test equipment; have backup equipment; create professional displays; select the best location to obtain a largest number of participants; use social media/www sites to promote the events; use many telescopes for multiple targets; project a live image or video; select equipment that is easy to

Music Inspired by Astronomy: A Selected Listing for the International Year of Astronomy

NASA Astrophysics Data System (ADS)

Fraknoi, A.

2008-11-01

Part of the aim of the International Year of Astronomy is to show the connections between astronomy and other areas of human culture. Such connections are easily found in music, where astronomical ideas have found a wide range of expression. This is not a comprehensive listing, but a sampling of some of the pieces that are available on CD's, and that may be of particular interest to educators and astronomy enthusiasts. To qualify for the list, a piece (or the composer's vision for it) has to include some real science and not just an astronomical term in the title or in a few lyrics. For example, we do not list The Planets, by Gustav Holst, since it treats the astrological view of the planets. And we regret that Philip Glass' opera Galileo is not available on CD and therefore cannot be listed. Nor do we include the thousands of popular songs that use the moon or the stars for an easy rhyme or a quick romantic image. And, while many jazz pieces have astronomy in the title, it is often hard to know just how the piece and the astronomy go together; so we've sadly omitted jazz too. For those with old-fashioned ears, like the author, we note that no warranty is made that all these pieces are easy to listen to, but each takes some key idea from astronomy and makes music out of it. A more comprehensive discussion can be found in my article in Astronomy Education Review: http://aer.noao.edu/cgi-bin/article.pl?id=193

"Radio Astronomy, Whatever That May Be." The Marginalization of Early Radio Astronomy

NASA Astrophysics Data System (ADS)

Jarrell, Richard

2005-01-01

Today we see radio astronomy as a fully-integrated part of astronomy; it is now just one of several available wavelength regimes and many astrophysicists who use radio data are not radio astronomers themselves. At the beginning, it was very different. Between 1946 and 1960, radio astronomy emerged as an important speciality but it was an area little understood by mainstream astronomers. Radio astronomers rarely published in astronomical journals, gave papers at astronomical conferences or were accorded much notice. The pioneers in the field were not astronomers themselves and had little in common with astronomers. In this paper I note the various ways in which radio astronomy was alienated from the mainstream in its first decade and some of the reasons this alienation occurred. I will also speculate on when and how the integration began to occur.

Astronomy Explained

NASA Astrophysics Data System (ADS)

North, Gerald

Every year large numbers of people take up the study of astronomy, mostly at amateur level. There are plenty of elementary books on the market, full of colourful photographs, but lacking in proper explanations of how and why things are as they are. Many people eventually wish to go beyond the 'coffee-table book' stage and study this fascinating subject in greater depth. This book is written for them. In addition, many people sit for public examinations in this subject each year and this book is also intended to be of use to them. All the topics from the GCSE syllabus are covered here, with sample questions at the end of each chapter. Astronomy Explained provides a comprehensive treatment of the subject in more depth than is usually found in elementary works, and will be of interest to both amateur astronomers and students of astronomy.

Teaching Astronomy Online

NASA Astrophysics Data System (ADS)

Radnofsky, Mary L.; Bobrowsky, Matthew

This article is intended to provide an overview of the practical, pedagogical, and philosophical considerations in designing a Web-based astronomy course, and to demonstrate the educational benefits that such online courses can afford students. Because online students need to take more responsibility for their learning, faculty must make course expectations extremely clear. Online education allows for increased student participation and equal access to college by such groups as the military, the handicapped, full-time employees, and rural and senior citizens. Teaching the sciences online--especially astronomy--gives students more time to think critically about new information. This article also includes tools, checklists, and resources helpful for introducing faculty to online course development in astronomy.

Astronomy, Astrology, and Medicine

NASA Astrophysics Data System (ADS)

Greenbaum, Dorian Gieseler

Astronomy and astrology were combined with medicine for thousands of years. Beginning in Mesopotamia in the second millennium BCE and continuing into the eighteenth century, medical practitioners used astronomy/astrology as an important part of diagnosis and prescription. Throughout this time frame, scientists cited the similarities between medicine and astrology, in addition to combining the two in practice. Hippocrates and Galen based medical theories on the relationship between heavenly bodies and human bodies. In an enduring cultural phenomenon, parts of the body as well as diseases were linked to zodiac signs and planets. In Renaissance universities, astronomy and astrology were studied by students of medicine. History records a long tradition of astrologer-physicians. This chapter covers the topic of astronomy, astrology, and medicine from the Old Babylonian period to the Enlightenment.

1989-02-01

The author discusses some of the more recent research on fractal astronomy and results presented in several astronomical studies. First, the large-scale structure of the universe is considered, while in another section one drops in scale to examine some of the smallest bodies in our solar system; the comets and meteoroids. The final section presents some thoughts on what influence the fractal ideology might have on astronomy, focusing particularly on the question recently raised by Kadanoff, "Fractals: where's the physics?"

Armenian Archaeoastronomy and Astronomy in Culture

NASA Astrophysics Data System (ADS)

Mickaelian, Areg M.; Farmanyan, Sona V.

2016-12-01

A review is given on archaeoastronomy in Armenia and astronomical knowledge reflected in the Armenian culture. Astronomy in Armenia was popular since ancient times and Armenia is rich in its astronomical heritage, such as the names of the constellations, ancient observatories, Armenian rock art (numerous petroglyphs of astronomical content), ancient and medieval Armenian calendars, astronomical terms and names used in Armenian language since II-I millennia B.C., records of astronomical events by ancient Armenians (e.g. Halley's comet in 87 B.C., supernovae explosion in 1054), the astronomical heritage of the Armenian medieval great thinker Anania Shirakatsi's (612-685), medieval sky maps and astronomical devices by Ghukas (Luca) Vanandetsi (XVII-XVIII centuries) and Mkhitar Sebastatsi (1676-1749), etc. For systemization and further regular studies, we have created a webpage devoted to Armenian archaeoastronomical matters at Armenian Astronomical Society (ArAS) website. Issues on astronomy in culture include astronomy in ancient Armenian cultures, ethnoastronomy, astronomy in Armenian religion and mythology, astronomy and astrology, astronomy in folklore and poetry, astronomy in arts, astrolinguistics and astroheraldry. A similar webpage for Astronomy in Armenian Culture is being created at ArAS website and a permanent section "Archaeoastronomy and Astronomy in Culture" has been created in ArAS Electronic Newsletter. Several meetings on this topic have been organized in Armenia during 2007-2014, including the archaeoastronomical meetings in 2012 and 2014, and a number of books have been published. Several institutions are related to these studies coordinated by Byurakan Astrophysical Observatory (BAO) and researchers from the fields of astronomy, history, archaeology, literature, linguistics, etc. are involved.

THE TEAM KECK REDSHIFT SURVEY 2: MOSFIRE SPECTROSCOPY OF THE GOODS-NORTH FIELD

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wirth, Gregory D.; Kassis, Marc; Lyke, Jim

We present the Team Keck Redshift Survey 2 (TKRS2), a near-infrared spectral observing program targeting selected galaxies within the CANDELS subsection of the GOODS-North Field. The TKRS2 program exploits the unique capabilities of the Multi-Object Spectrometer For Infra-Red Exploration (MOSFIRE), which entered service on the Keck I telescope in 2012 and contributes substantially to the study of galaxy spectral features at redshifts inaccessible to optical spectrographs. The TKRS2 project targets 97 galaxies drawn from samples that include z ≈ 2 emission-line galaxies with features observable in the JHK bands as well as lower-redshift targets with features in the Y band.more » We present a detailed measurement of MOSFIRE’s sensitivity as a function of wavelength, including the effects of telluric features across the YJHK filters. The largest utility of our survey is in providing rest-frame-optical emission lines for z > 1 galaxies, and we demonstrate that the ratios of strong, optical emission lines of z ≈ 2 galaxies suggest the presence of either higher N/O abundances than are found in z ≈ 0 galaxies or low-metallicity gas ionized by an active galactic nucleus. We have released all TKRS2 data products into the public domain to allow researchers access to representative raw and reduced MOSFIRE spectra.« less

The Teaching of Astronomy in Mauritius

NASA Astrophysics Data System (ADS)

Heeralall-Issur, Nalini

In this presentation we describe the present teaching of Astronomy in Mauritius. At present Astronomy is taught mostly at University level as electives (Astrophysics I & II) within our BSc Physics course or the MSc Physics with Astrophysics Specialisation Option. However there are limitations due to both facilities available & staff resources at the higher level. At the lower level very few secondary school students are exposed to (taught) astronomy and even among well educated adults many ignore very basic knowledge of Astronomy. We finally discuss some realistic suggestions for improving the teaching of Astronomy at all levels in Mauritius.

Conceptual frameworks in astronomy

NASA Astrophysics Data System (ADS)

Pundak, David

2016-06-01

How to evaluate students' astronomy understanding is still an open question. Even though some methods and tools to help students have already been developed, the sources of students' difficulties and misunderstanding in astronomy is still unclear. This paper presents an investigation of the development of conceptual systems in astronomy by 50 engineering students, as a result of learning a general course on astronomy. A special tool called Conceptual Frameworks in Astronomy (CFA) that was initially used in 1989, was adapted to gather data for the present research. In its new version, the tool included 23 questions, and five to six optional answers were given for each question. Each of the answers was characterized by one of the four conceptual astronomical frameworks: pre-scientific, geocentric, heliocentric and sidereal or scientific. The paper describes the development of the tool and discusses its validity and reliability. Using the CFA we were able to identify the conceptual frameworks of the students at the beginning of the course and at its end. CFA enabled us to evaluate the paradigmatic change of students following the course and also the extent of the general improvement in astronomical knowledge. It was found that the measure of the students’ improvement (gain index) was g = 0.37. Approximately 45% of the students in the course improved their understanding of conceptual frameworks in astronomy and 26% deepened their understanding of the heliocentric or sidereal conceptual frameworks.

Astronomy in New Zealand

NASA Astrophysics Data System (ADS)

Hearnshaw, John B.

2006-01-01

Although New Zealand is a young country, astronomy played a significant role in its early exploration and discovery during the three voyages of Cook from 1769. In the later 19th century several expeditions came to New Zealand to observe the transits of Venus of 1874 and 1882 and New Zealand's rich history of prominent amateur astronomers dates from this time. The Royal Astronomical Society of New Zealand (founded in 1920) has catered for the amateur community. Professional astronomy however had a slow start in New Zealand. The Carter Observatory was founded in 1941. But it was not until astronomy was taken up by New Zealand's universities, notably by the University of Canterbury from 1963, that a firm basis for research in astronomy and astrophysics was established. Mt John University Observatory with its four optical telescopes (largest 1.8 m) is operated by the University of Canterbury and is the main base for observational astronomy in the country. However four other New Zealand universities also have an interest in astronomical research at the present time. There is also considerable involvement in large international projects such as MOA, SALT, AMOR, IceCube and possibly SKA.

Trio of stellar occultations by Pluto One Year Prior to New Horizons' Arrival

2015-01-01

Our campaign in July 2014 yielded three successful stellar occultations (~m=15, 17, and 18) of Pluto (~m=14), observed from telescopes in New Zealand, Australia, and Chile. Telescopes involved included Chile: Magellan's Clay (6.5 m), SOAR (4.1 m), Carnegie's DuPont (2.4 m); Australia: AAT (4 m); and Canterbury's Mt. John McLellan (1-m); as well as various smaller telescopes in Australia and Chile. One of the events was also observed, with negative results, from GROND on La Silla (2.2 m) and SMARTS's ANDICAM at CTIO (1.3 m). Though our observations were coordinated across continents, each successfully observed event was seen from only one site because of bad weather at the other sites. Two of the events were uniquely observed from Mt. John (Pasachoff et al., DPS 2014) and one, with only Chile sites in the predicted path, from the Clay (Person et al., DPS 2014). This last event was expected to be of the brightest star with the largest telescope we have ever observed for a Pluto occultation, but clouds arrived at the 6.5-m Clay 90 s before the predicted time; a 1% occultation was nonetheless seen and eventually, confirmed by Keck AO observations, to be of a 15th magnitude star previously hidden in the brightness of the 12th mag star. Our scientific conclusion is that as of these observations, one year before New Horizons' passage of Pluto, the atmosphere of Pluto remained robust and of the same size. Details on our analysis of the three events will be presented.Acknowledgments: This work was supported in part by NASA Planetary Astronomy grants to Williams College (NNX12AJ29G) and to MIT (NNX10AB27G), as well as grants from USRA (#8500-98-003) and Ames Research (#NAS2-97-01) to Lowell Observatory.

Creation of an instrument maintenance program at W. M. Keck Observatory

NASA Astrophysics Data System (ADS)

Hill, G. M.; Kwok, S. H.; Mader, J. A.; Wirth, G. D.; Dahm, S. E.; Goodrich, R. W.

2014-08-01

Until a few years ago, the W. M. Keck Observatory (WMKO) did not have a systematic program of instrument maintenance at a level appropriate for a world-leading observatory. We describe the creation of such a program within the context of WMKO's lean operations model which posed challenges but also guided the design of the system and resulted in some unique and notable capabilities. These capabilities and the flexibility of the system have led to its adoption across the Observatory for virtually all PM's. The success of the Observatory in implementing the program and its impact on instrument reliability are presented. Lessons learned are reviewed and strategic implications discussed.

Innovative Technology for Teaching Introductory Astronomy

NASA Astrophysics Data System (ADS)

Guidry, Mike

The application of state-of-the-art technology (primarily Java and Flash MX Actionscript on the client side and Java PHP PERL XML and SQL databasing on the server side) to the teaching of introductory astronomy will be discussed. A completely online syllabus in introductory astronomy built around more than 350 interactive animations called ""Online Journey through Astronomy"" and a new set of 20 online virtual laboratories in astronomy that we are currently developing will be used as illustration. In addition to demonstration of the technology our experience using these technologies to teach introductory astronomy to thousands of students in settings ranging from traditional classrooms to full distance learning will be summarized. Recent experiments using Java and vector graphics programming of handheld devices (Personal Digital Assistants and cell phones) with wireless wide-area connectivity for applications in astronomy education will also be described.

World Wide Web Astronomy 2.0

Koppelman, M.; Gay, P. L.

2008-11-01

The Internet has changed astronomy. It's changed research, outreach and education and it's changed how people consume astronomy as enthusiasts. People have new ways to talk to each other and new ways to participate. Coined ``Web 2.0,'' technologies such as blogs, social networks, wikis, photo and video sharing sites, podcasts and micro-blogging have been adopted by the astronomy community and exciting things are happening as a result. The International Year of Astronomy's New Media Task Force has been working to harness the excitement of ``Web 2.0'' to make the International Year of Astronomy (IYA2009) highly visible on the Internet around the world.

White supremacism and Islamic astronomy in history of astronomy texts from the eighteenth century to the present day

NASA Astrophysics Data System (ADS)

Lockard, Joe

2018-04-01

This paper reviews manifestations of racism in European and American histories of Arab and Persian astronomy from the eighteenth century to the present day. Its first section discusses representation of Islamic astronomy from Adam Smith to late Victorian writers, particularly tracing ideas of Arab unoriginality and scientific incapacity. The second section first relates the appearance of scientific racism in the early twentieth-century historiography of astronomy, then how the rise of scientifically and linguistically competent scholarship in the latter twentieth century provided much-improved information on Islamic achievements in astronomy. The paper’s conclusion underlines the importance of avoiding ethnic supremacism and integrating research on Islamic astronomy into teaching and publishing on the history of astronomy.

NASA Astrophysics Data System (ADS)

Knierman, K. A.; McCarthy, D. W.; Schutz, K.

2005-12-01

To help encourage a new generation of women in science, we have created Astronomy Patch Day for the Sahuaro Girl Scout Council in Tucson, Arizona. This all-day event is an interactive experience for Girl Scouts ages 5-18 to learn about astronomical concepts and women in astronomy. Our first Astronomy Patch Day, held on March 19, 2005, in conjunction with the Sahuaro Council's annual Science, Math, and Related Technologies (SMART) program, was very successful, reaching about 150-200 girls and their leaders. Individual troops rotated every half hour among our six activity booths: Earth-Moon, Solar System, Stars, Galaxies, Universe, and Ask an Astronomer, which were staffed by trained Girl Scout Leaders as well as faculty, post-doctoral researchers, and graduate students from Steward Observatory. To earn a patch, younger girls (ages 5-12) had to complete activities at three booths and older girls had to complete all six activities. Positive feedback for this event was received from both the girls and leaders. We plan to hold Astronomy Patch Day annually, possibly with different and/or additional activities in future years. K. Knierman is supported by an Arizona/NASA Space Grant Fellowship. This outreach program is supported by NIRCam/JWST E/PO.

Brown dwarf distances and atmospheres: Spitzer Parallaxes and the Keck/NIRSPEC upgrade

NASA Astrophysics Data System (ADS)

Martin, Emily C.

2018-01-01

Advances in infrared technology have been essential towards improving our understanding of the solar neighborhood, revealing a large population of brown dwarfs, which span the mass regime between planets and stars. My thesis combines near-infrared (NIR) spectroscopic and astrometric analysis of nearby low-mass stars and brown dwarfs with instrumentation work to upgrade the NIRSPEC instrument for the Keck II Telescope. I will present results from a program using Spitzer/IRAC data to measure precise locations and distances to 22 of the coldest and closest brown dwarfs. These distances allow us to constrain absolute physical properties, such as mass, radius, and age, of free-floating planetary-mass objects through comparison to atmospheric and evolutionary models. NIR spectroscopy combined with the Spitzer photometry reveals a detailed look into the atmospheres of brown dwarfs and gaseous extrasolar planets. Additionally, I will discuss the improvements we are making to the NIRSPEC instrument at Keck. NIRSPEC is a NIR echelle spectrograph, capable of R~2000 and R~25,000 observations in the 1-5 μm range. As part of the upgrade, I performed detector characterization, optical design of a new slit-viewing camera, mechanical testing, and electronics design. NIRSPEC’s increased efficiency will allow us to obtain moderate- and high-resolution NIR spectra of objects up to a magnitude fainter than the current NIRSPEC design. Finally, I will demonstrate the utility of a NIR laser frequency comb as a high-resolution calibrator. This new technology will revolutionize precision radial velocity measurements in the coming decade.

Astronomy in Australia

NASA Astrophysics Data System (ADS)

Watson, F.; Couch, W.

2017-12-01

Australians have watched the sky for tens of thousands of years. The nineteenth century saw the foundation of government observatories in capital cities such as Sydney and Melbourne. While early twentieth-century astronomy focused largely on solar physics, the advent of radio astronomy at the end of the Second World War enabled Australia to take a leading role in the new science, with particular emphasis on low-frequency studies. Today, the radio quietness of its outback interior provides an excellent location for the Australian core of the Square Kilometre Array. Australian optical astronomy has flourished since the 1960s, with the 3.9-metre Anglo-Australian Telescope becoming the principal national facility in 1974. Access to ESO’s facilities at the La Silla Paranal Observatory is warmly welcomed by all Australian astronomers.

Astronomy in Antarctica

NASA Astrophysics Data System (ADS)

Burton, Michael G.

2010-10-01

Antarctica provides a unique environment for astronomers to practice their trade. The cold, dry and stable air found above the high Antarctic plateau, as well as the pure ice below, offers new opportunities for the conduct of observational astronomy across both the photon and the particle spectrum. The summits of the Antarctic plateau provide the best seeing conditions, the darkest skies and the most transparent atmosphere of any earth-based observing site. Astronomical activities are now underway at four plateau sites: the Amundsen-Scott South Pole Station, Concordia Station at Dome C, Kunlun Station at Dome A and Fuji Station at Dome F, in addition to long duration ballooning from the coastal station of McMurdo, at stations run by the USA, France/Italy, China, Japan and the USA, respectively. The astronomy conducted from Antarctica includes optical, infrared, terahertz and sub-millimetre astronomy, measurements of cosmic microwave background anisotropies, solar astronomy, as well as high energy astrophysics involving the measurement of cosmic rays, gamma rays and neutrinos. Antarctica is also the richest source of meteorites on our planet. An extensive range of site testing measurements have been made over the high plateau sites. In this article, we summarise the facets of Antarctica that are driving developments in astronomy there, and review the results of the site testing experiments undertaken to quantify those characteristics of the Antarctic plateau relevant for astronomical observation. We also outline the historical development of the astronomy on the continent, and then review the principal scientific results to have emerged over the past three decades of activity in the discipline. These range from determination of the dominant frequencies of the 5 min solar oscillation in 1979 to the highest angular scale measurements yet made of the power spectrum of the CMBR anisotropies in 2010. They span through infrared views of the galactic ecology in star

Grade 9 Astronomy Study: Interests of Boys and Girls Studying Astronomy at Fletcher's Meadow Secondary School

NASA Astrophysics Data System (ADS)

Krstovic, Mirjan; Brown, Laura; Chacko, Merin; Trinh, Brenda

In this report, we discuss the interests of Grade 9 boys and girls studying astronomy at Fletcher's Meadow Secondary School in Brampton, Ontario. A total of 152 Grade 9 academic students were asked to rate their interest levels in various astronomy topics on a scale of 0 3, where 0 represented no interest and 3 represented a high level of interest. We also asked the students to rate all the in-class activities on the same scale. Our analysis of the data suggests that there are many similarities in interest levels in various astronomy topics between boys and girls. In addition, boys and girls expressed similar preferences for in-class astronomy activities with only minor differences, suggesting similar learning styles in astronomy for boys and girls at the Grade 9 level.

2008-09-01

Selection from past astronomy education, activities, textbooks and curricula will be presented. Didactic aspects and comparison with physics education will be exemplified. The astronomy/science education along the time in Romania was roughly divided in four directions: very broad information texts for everybody, popular science, school textbooks, science fictions and astronomy/science literature, and exemplified using original texts. All categories were intended to extend literacy in science, but in different ways. The trends for different periods were outlined. The teaching of astronomy and astrophysics in high school and universities, with special attention to the Faculty of Physic from University of Bucharest are presented. Suggestions for future improvement of both related fields, physics and astronomy, will be one of the outcomes of our communication.

With more than 3,000 alphabetically arranged entries and 500 stunning color and black-and-white photographs, star maps, and diagrams, The Astronomy Encyclopedia covers everything that the general enthusiast--and the more serious researcher--would want to know about planets, stars, galaxies, and our universe. Here is concise, reliable information on the whole field of astronomy, ranging from adaptive optics and cold dark matter, to Islamic astronomy and the lens defect known as vignetting. It includes a host of major articles on the cornerstones of astronomical investigation, such as the Milky Way, the sun and the planets, optical and radio telescopes, stars, black holes, astrophysics, observatories, astronomical photography, space programs, the constellations, and famous astronomers. And there are concise entries on planetary features and satellites, asteroids, observational techniques, comets, satellite launchers, meteors, and subjects as diverse as life in the Universe and the structure of meteorites. Scores of tables list the brightest stars in the major constellations, annual meteor showers, major variable stars, dwarf stars, energy production processes in the Sun, and other relevant data. More than 100 astronomers from leading universities and observatories around the world, each an expert in their own particular field, wrote and reviewed the entries to ensure their authority. Readers can thus be assured that the Encyclopedia provides the most up-to-date and reliable information available. Under the general editorship of Patrick Moore, one of the world's best-known and most trusted voices on astronomy, The Astronomy Encyclopedia is an authoritative and strikingly attractive roadmap for exploring the last great frontier of the world in which we live.

The Atmosphere of Uranus as Imaged with Keck Adaptive Optics

NASA Astrophysics Data System (ADS)

Hammel, H. B.; de Pater, I.; Gibbard, S. G.; Lockwood, G. W.; Rages, K.

2004-12-01

Adaptive optics imaging of Uranus was obtained with NIRC2 on the Keck II 10-meter telescope in October 2003 and July 2004 through J, H, and K' filters. Dozens of discrete features were detected in the atmosphere of Uranus. We report the first measurements of winds northward of +43 deg, the first direct measurement of equatorial winds, and the highest wind velocity seen yet on Uranus. At northern mid-latitudes, the winds may have accelerated when compared to earlier HST and Keck observations; southern wind speeds have not changed since Voyager measurements in 1986. The equator of Uranus exhibits a subtle wave structure, with diffuse patches roughly every 30 degs in longitude. There is no sign of a northern "polar collar" as is seen in the south, but a number of discrete features seen at the "expected" latitudes may signal its early stages of development. The largest cloud features on Uranus show complex structure extending over tens of degrees. On 4 July 2004, we detected a southern hemispheric cloud feature on Uranus at K', the first detection of a southern feature at or longward of 2 microns. H images showed an extended structure whose condensed core was co-located with the K'-bright feature. The core exhibited marked brightness variation, fading within just a few days. The initial brightness at K' indicates that the core's scattering particles reached altitudes above the 1-bar level, with the extended H feature residing below 1.1 bars. The core's rapid disappearance at K' indicates dynamical processes in the local vertical aerosol structure. HBH acknowledges support from NASA grants NAG5-11961 and NAG5-10451.

It is argued that astronomy makes unexpectantly large contributions to formal and informal science education, given the small number of research astronomers. Technology transfer and spin-offs from astronomy have important applications in medicine, industry, defence, environmental monitoring, and consumer products. Astronomy provides unusually promising opportunities for international cooperation. Other sciences benefit from synergistic interactions with astronomy. A review is given of astronomy education and teacher training. The role of astronomy in medicine, industry, defence, energy technology, the environment, and everyday life is reviewed.

Mathematical Astronomy in India

NASA Astrophysics Data System (ADS)

Plofker, Kim

Astronomy in South Asia's Sanskrit tradition, apparently originating in simple calendric computations regulating the timing of ancient ritual practices, expanded over the course of two or three millennia to include detailed spherical models, an endless variety of astrological systems, and academic mathematics in general. Assimilating various technical models, methods, and genres from the astronomy of neighboring cultures, Indian astronomers created new forms that were in turn borrowed by their foreign counterparts. Always recognizably related to the main themes of Eurasian geocentric mathematical astronomy, Indian astral science nonetheless maintained its culturally distinct character until Keplerian heliocentrism and Newtonian mechanics replaced it in colonial South Asia's academic mainstream.

Discovering Astronomy Through Poetry

NASA Astrophysics Data System (ADS)

Mannone, John C.

2011-05-01

The literature is replete with astronomical references. And much of that literature is poetry. Using this fact, not only can the teacher infuse a new appreciation of astronomy, but also, the student has the opportunity to rediscover history through astronomy. Poetry can be an effective icebreaker in the introduction of new topics in physics and astronomy, as well as a point of conclusion to a lecture. This presentation will give examples of these things from the ancient literature (sacred Hebraic texts), classical literature (Homer's Iliad and Odyssey), traditional poetry (Longfellow, Tennyson and Poe) and modern literature (Frost, Kooser, and others, including the contemporary work of this author).

Astronomy Education Under Dark Skies

Cecylia Molenda-Zakowicz, Joanna

2015-08-01

We have been providing professional support for the high school students and the astronomy teachers since 2007. Our efforts include organizing astronomy events that take from several hours, like, e.g., watching the transit of Venus, to several days, like the workshops organized in the framework of the projects 'School Workshops on Astronomy' (SWA) and 'Wygasz'.The SWA and Wygasz workshops include presentations by experts in astronomy and space science research, presentations prepared by students being supervised by those experts, hands-on interactive experience in the amateur astrophotography, various pencil-and-paper exercises, and other practical activities. We pay particular attention to familiarize the teachers and students with the idea and the necessity of protecting the dark sky. The format of these events allows also for some time for teachers to share ideas and best practices in teaching astronomy.All those activities are organized either in the Izera Dark-Sky Park in Poland or in other carefuly selected locations in which the beauty of the dark night sky can be appreciated.

Langland-Shula, Laura E.; Vogt, Steven S.; Charbonneau, David; Butler, Paul; Marcy, Geoff

2009-05-01

We present high-resolution High Resolution Echelle Spectrometer (HIRES)/Keck spectra of HD 209458, and a Monte Carlo variation on the basic method used by other workers, to look for the excess in-transit absorption in the NaD doublet at 5893 Å due to the extrasolar planet. The HIRES data, binned by bandpass, allow a direct comparison with previous results. We find >3σ results in most test bandpasses around the NaD doublet, including relative absorption of (-108.8 ± 25.7) × 10-5 in the "narrow" bandpass used by other workers. This is ≈4.7 times larger than the "narrow" results reported by Charbonneau et al. for HD 209458b. However, >2σ absorption is detected in some weak Fe I and Ni I lines that were tested for comparison, raising concern about the uncertainties introduced by continuum-fitting and terrestrial atmosphere subtraction. Based on data obtained with the W. M. Keck Observatory, which is operated by a partnership consisting of the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration.

Europe's Astronomy Teachers Meet at ESO

NASA Astrophysics Data System (ADS)

1994-12-01

European Association for Astronomy Education Formed A joint EU/ESO Workshop (1) on the Teaching of Astronomy in Europe was held at the ESO Headquarters from November 25-30, 1994, under the auspices of the 1994 European Week for Scientific Culture. More than 100 teachers from secondary schools in 17 European countries participated together with representatives of national ministries and local authorities, as well as professional astronomers. This meeting was the first of its kind ever held and was very successful. As a most visible and immediate outcome, the participants agreed to form the "European Association for Astronomy Education (EAAE)", uniting astronomy educators all over Europe into one network. A provisional Executive Committee of the EAAE was elected which will work towards the organisation of a constitutional conference within the next year. The participants unanimously adopted a "Declaration on the Teaching of Astronomy in Europe", specifying the overall aims and initial actions needed to achieve them. Astronomy: Science, Technology and Culture At the beginning of the Workshop the participants listened to lectures by several specialists about some of the most active fields of astronomy. The scientific sessions included topics as diverse as minor bodies in the solar system, nucleosynthesis, interstellar chemistry and cosmology. Then followed overviews of various recent advances in astronomical technology, some of which are already having direct impact on highly specialized sectors of European industry. They included the advanced use of computers in astronomy, for instance within image processing and data archiving, as well as a demonstration of remote observing. Discussing the cultural aspects, Nigel Calder (UK) and Hubert Reeves (France) emphasized the important role of astronomy in modern society, in particular its continuing influence on our perceptions of mankind's unique location in time and space.

Demographics in Astronomy and Astrophysics

NASA Astrophysics Data System (ADS)

Ulvestad, James S.

2011-05-01

Astronomy has been undergoing a significant demographic shift over the last several decades, as shown by data presented in the 2000 National Research Council (NRC) report "Federal Funding of Astronomical Research," and the 2010 NRC report, "New Worlds, New Horizons in Astronomy and Astrophysics." For example, the number of advertised postdoctoral positions in astronomy has increased much more rapldly than the number of faculty positions, contributing to a holding pattern of early-career astronomers in multiple postdoctoral positions. This talk will summarize some of the current demographic trends in astronomy, including information about gender and ethnic diversity, and describe some of the possible implications for the future. I thank the members of the Astro2010 Demographics Study Group, as well as numerous white-paper contributors to Astro2010, for providing data and analyses.

Ancient Indian Astronomy in Introductory Texts

NASA Astrophysics Data System (ADS)

Narahari Achar, B. N.

1997-10-01

It is customary in introductory survey courses in astronomy to devote some time to the history of astronomy. In the available text books only the Greek contribution receives any attention. Apart from Stonehenge and Chichenitza pictures, contributions from Babylon and China are some times mentioned. Hardly any account is given of ancient Indian astronomy. Even when something is mentioned it is incomplete or incorrect or both. Examples are given from several text books currently available. An attempt is made to correct this situation by sketching the contributions from the earliest astronomy of India, namely Vedaanga Jyotisha.

Demonstrations in astronomy classes seem to be more necessary than in physics classes for three reasons. First, many of the events are very large scale and impossibly remote from human senses. Secondly, while physics courses use discussions of one- and two-dimensional motion, three-dimensional motion is the normal situation in astronomy; thus,…

Music and Astronomy Under the Stars

Bring telescope to where the people are! Music and Astronomy Under the Stars is a public astronomy outreach program at community parks during and after free summer music concerts and outdoor movie nights. This project also includes daytime activities because there are some afternoon concerts and daylight children's concerts, and observations using remotely operated telescopes in cloudy weather. While there have been many astronomy outreach activities and telescope observations at city sidewalks and parks, this program targets a completely different audience---music lovers who are attending free summer concerts held in community parks. The music lovers who may never have visited a science museum, planetarium, or star party will be exposed to telescope observations and astronomy information with no additional travel costs. This program will permit the entire community to participate in telescope observations and view astronomical video information to enhance the public appreciation of astronomy. This program will also reach underrepresented and underserved groups (women, minorities, older adults). The population base for the initial target audience (Nassau and Suffolk Counties, New York) is 2,500,000. My partners are the Amateur Observers' Society of New York (AOS) and the Towns of Oyster Bay, Hempstead, North Hempstead, and Huntington. Music and Astronomy Under the Stars is program that should continue beyond the International Year of Astronomy 2009 (IYA2009) and can be expanded into a national program.

Rescuing Middle School Astronomy

NASA Astrophysics Data System (ADS)

Mayo, L. A.; Janney, D.

2010-12-01

There is a crisis in education at the middle school level (Spellings, 2006). Recent studies point to large disparities in middle school performance in schools with high minority populations. The largest disparities exist in areas of math and science. Astronomy has a universal appeal for K-12 students but is rarely taught at the middle school level. When it is taught at all it is usually taught in isolation with few references in other classes such as other sciences (e.g. physics, biology, and chemistry), math, history, geography, music, art, or English. The problem is greatest in our most challenged school districts. With scores in reading and math below national averages in these schools and with most state achievement tests ignoring subjects like astronomy, there is little room in the school day to teach about the world outside our atmosphere. Add to this the exceedingly minimal training and education in astronomy that most middle school teachers have and it is a rare school that includes any astronomy teaching at all. In this presentation, we show how to develop and offer an astronomy education training program for middle school teachers encompassing a wide range of educational disciplines that are frequently taught at the middle school level. The prototype for this program was developed and launched in two of the most challenged and diverse school systems in the country; D.C. Public Schools, and Montgomery County (MD) Public Schools.

Bring telescopes to where the people are! Music and Astronomy Under the Stars is a three-year NASA-funded astronomy outreach program at community parks during and after music concerts and outdoor family events—such as a Halloween Stars-Spooky Garden Walk. While there have been many astronomy outreach activities and telescope observations at city sidewalks and parks, this program targets a completely different audience: music lovers who are attending summer concerts held in community parks. These music lovers who may never have visited a science museum, planetarium, or star party are exposed to telescope observations and astronomy information with no additional travel costs. Music and Astronomy Under the Stars increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. This program includes solar observing before the concerts, telescope observations including a live image projection system, an astronomical video presentation, and astronomy banners/posters. Approximately 500-16,000 people attended each event and 25% to 50% of the people at each event participated in the astronomy program. This program also reached underrepresented and underserved groups (women, minorities, older adults). The target audience (Nassau and Suffolk Counties, New York) is 2,900,000 people, which is larger than combined population of Atlanta, Boston, Denver, Minneapolis, and San Francisco. Although eleven events were planned in 2009, two were canceled due to rain and our largest event, the NY Philharmonic in the Park (attended by 67,000 people in 2008), was cancelled for financial reasons. Our largest event in 2009 was the Tanglewood Music Festival, Lenox MA, attended by 16,000 people where over 5000 people participated in astronomy activities. The Amateur Observers' Society of New York assisted with the NY concerts and the Springfield STARS astronomy club assisted at Tanglewood. In 2009 over 15,000 people participated in astronomy

Keck Deep Fields. II. The Ultraviolet Galaxy Luminosity Function at z ~ 4, 3, and 2

NASA Astrophysics Data System (ADS)

Sawicki, Marcin; Thompson, David

We use very deep UnGRI multifield imaging obtained at the Keck telescope to study the evolution of the rest-frame 1700 Å galaxy luminosity function as the universe doubles its age from z~4 to ~2. We use exactly the same filters and color-color selection as those used by the Steidel team but probe significantly fainter limits, well below L*. The depth of our imaging allows us to constrain the faint end of the luminosity function, reaching M1700~-18.5 at z~3 (equivalent to ~1 Msolar yr-1), accounting for both N1/2 uncertainty in the number of galaxies and cosmic variance. We carefully examine many potential sources of systematic bias in our LF measurements before drawing the following conclusions. We find that the luminosity function of Lyman break galaxies evolves with time and that this evolution is differential with luminosity. The result is best constrained between the epochs at z~4 and ~3, where we find that the number density of sub-L* galaxies increases with time by at least a factor of 2.3 (11 σ statistical confidence); while the faint end of the LF evolves, the bright end appears to remain virtually unchanged, indicating that there may be differential, luminosity-dependent evolution (98.5% statistical probability). Potential systematic biases restrict our ability to draw strong conclusions about continued evolution of the luminosity function to lower redshifts, z~2.2 and ~1.7, but, nevertheless, it appears certain that the number density of z~2.2 galaxies at all luminosities we studied, -22>M1700>-18, is at least as high as that of their counterparts at z~3. While it is not yet clear what mechanism underlies the observed evolution, the fact that this evolution is differential with luminosity opens up new avenues of improving our understanding of how galaxies form and evolve at high redshift. Based on data obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of

The Moon offers both significant advantages and drawbacks for astronomy. Recognition of these characteristics can clarify the objectives toward which developments should be directed and can help to inhibit premature or excessive selling of lunar developments on the basis of astronomy.

Chaco astronomies

Martín López, Alejandro

2015-08-01

This presentation discusses the result of 18 years of ethnographic and ethnohistorical studies on Chaco astronomies. The main features of the systems of astronomical knowledge of the Chaco Aboriginal groups will be discussed. In particular we will discuss the relevance of the Milky Way, the role of the visibility of the Pleiades, the ways in which the celestial space is represented, the constitution of astronomical orientations in geographic space, etc. We also address a key feature of their vision of the cosmos: the universe is seen by these groups as a socio-cosmos, where humans and non-humans are related. These are therefore actually socio-cosmologies. We will link this to the theories of Chaco Aboriginal groups about power and political relations.We will discuss how the study of Aboriginal astronomies must be performed along with the studies about astronomies of Creole people and European migrants, as well as anthropological studies about the science teaching in the formal education system and by the mass media. In this form we will discuss the relevance of a very complex system of interethnic relations for the conformation of these astronomical representations and practices.We will also discuss the general methodological implications of this case for the ethnoastronomy studies. In particular we will talk about the advantages of a study of regional scope and about the key importance of put in contact the ethnoastronomy with contemporary issues in social sciences.We also analyze the importance of ethnoastronomy studies in relation to studies of sociology of science, especially astronomy. We also study the potential impact on improving formal and informal science curricula and in shaping effective policies to protect the tangible and intangible astronomical heritage in a context of respect for the rights of Aboriginal groups.

The second Python in Astronomy conference will be held from 21-25 March 2016 at the University of Washington eScience Institute in Seattle, WA, USA. Similarly to the 2015 meeting (which was held at the Lorentz Center), we are aiming to bring together researchers, Python developers, users, and educators. The conference will include presentations, tutorials, unconference sessions, and coding sprints. In addition to sharing information about state-of-the art Python Astronomy packages, the workshop will focus on improving interoperability between astronomical Python packages, providing training for new open-source contributors, and developing educational materials for Python in Astronomy. The meeting is therefore not only aimed at current developers, but also users and educators who are interested in being involved in these efforts.

Astronomy Librarian - Quo Vadis?

NASA Astrophysics Data System (ADS)

Lagerstrom, Jill; Grothkopf, Uta

"You don't look like a librarian" is a phrase we often hear in the astronomy department or observatory library. Astronomy librarians are a breed apart, and are taking on new and non-traditional roles as information technology evolves. This talk will explore the future of librarians and librarianship through the lens of some of the recent talks given at the sixth "Libraries and Information Services in Astronomy" conference held in Pune, India in February 2010. We will explore the librarian's universe, illustrating how librarians use new technologies to perform such tasks as bibliometrics, how we are re-fashioning our library spaces in an increasingly digital world and how we are confronting the brave new world of Open Access, to name but a few topics.

Astronomy Week in Madeira, Portugal

NASA Astrophysics Data System (ADS)

Augusto, P.; Sobrinho, J. L.

2012-05-01

The outreach programme Semanas da Astronomia (Astronomy Weeks) is held in late spring or summer on the island of Madeira, Portugal. This programme has been attracting enough interest to be mentioned in the regional press/TV/radio every year and is now, without doubt, the astronomical highlight of the year on Madeira. We believe that this programme is a good case study for showing how to attract the general public to astronomy in a small (population 250 000, area 900 km2) and fairly isolated place such as Madeira. Our Astronomy Weeks have been different each year and have so far included exhibitions, courses, talks, a forum, documentaries, observing sessions (some with blackouts), music and an astro party. These efforts may contribute towards putting Madeira on the map with respect to observational astronomy, and have also contributed to the planned installation of two observatories in the island.

History of Astronomy in Moldova

NASA Astrophysics Data System (ADS)

Gaina, A.

The epoch of Stephen the Great (1457-1504) were marked in Moldova by a developement of astronomy in the connection with interests for navigation. Moldavian ships triped from Cetatea Alba (actualy Belgorod-Dniestrovskii, Odessa region, Ukraine) on Dniester gulf of the Black Sea to Genova and Venice. Other moldavian hospodars after the falling down of Moldova under the ottoman domination made attempts to develope astronomy as well as other natural sciences. Between them: Petru Rares (1527-1538, 1541-1546) and Demetrios Cantemir (1673-1723). The founder of the modern astronomy in Bessarabia is Nicolas N. Donitch (b. 1/13 september 1874 in Chisinau - d. 1956 or 1958 in Nice (?), France), member of the IAU since 1922, member of the russian, german, french and other astronomical societies, Honorary member of the Romanian Academy (1922-1948, reestablished in 1991). Donitch built the first private astronomical observatory in Starya Dubbosary (actualy Dubasarii-Vechi) in 1908. He dealt with solar and planet physics and astronomy, small bodies in solar system, meteorites researches, comet and solar eclipses observations, zodiacal light. After 1945 he worked in France. Now we have an astronomical observatory at the University and about 20 astronomers dealing with various branches of astronomy: from relativistic astrophysics and variable stars to solar system astronomy, celestial mechanics and atmospheric optics. We have a number of internationally recognized astronomers borne in Bessarabia or of Moldavian origin, worked in other countries, except Nicolas Donitch. Between them: V.A.Albitzky (1981-1951), A.N.Deutsch (1899-1968), N.Florea (1912-1941), V. Nadolschi, E.A.Grebenikov, M. Stavinschi and other.

Astronomy for teachers: A South African Perspective

NASA Astrophysics Data System (ADS)

de Witt, Aletha; West, Marion; Leeuw, Lerothodi; Gouws, Eldrie

2015-08-01

South Africa has nominated Astronomy as a “flagship science” and aims to be an international Astronomy hub through projects such as the Square Kilometre Array (SKA) and the South African Large Telescope (SALT). These projects open up career opportunities in maths, science and engineering and therefore offers a very real door for learners to enter into careers in science and technology through Astronomy. However, the Trends in International Mathematics and Science Survey (TIMSS), the Global Competitiveness Report (GCR) and Annual National Assessment (ANA) have highlighted that South Africa’s Science and Mathematics education is in a critical condition and that South African learners score amongst the worst in the world in both these subjects. In South Africa Astronomy is generally regarded as the worst taught and most avoided Natural Science knowledge strand, and most teachers that specialised in Natural Sciences, never covered Astronomy in their training.In order to address these issues a collaborative project between the University of South Africa (UNISA) and the Hartebeesthoek Radio Astronomy Observatory (HartRAO) was initiated, which aims to assist teachers to gain more knowledge and skills so that they can teach Astronomy with confidence. By collaborating we aim to ensure that the level of astronomy development will be raised in both South Africa and the rest of Africa.With the focus on Teaching and Learning, the research was conducted within a quantitative paradigm and 600 structured questionnaires were administered to Natural Science teachers in Public primary schools in Gauteng, South Africa. This paper reports the findings of this research and makes recommendations on how to assist teachers to teach Astronomy with confidence.

Launching Astronomy: Standards and STEM Integration (LASSI)

NASA Astrophysics Data System (ADS)

French, Debbie; Burrows, Andrea C.; Myers, Adam D.

2015-01-01

While astronomy is prevalent in the Next Generation Science Standards, it is often relegated to the '4th nine-weeks' in middle and high school curricula. I.e., it is taught at the end of the year, if time permits. However, astronomy ties in many core ideas from chemistry, earth science, physics, and even biology (with astrobiology being an up-and-coming specialization) and mathematics. Recent missions to Mars have captured students' attention and have added excitement to the fields of engineering and technology. Using astronomy as a vehicle to teach science, technology, engineering, and mathematics (STEM) connects these disciplines in an engaging way. The workshop entitled, 'Launching Astronomy: Standards and STEM Integration,' (LASSI) is a year-long professional development (PD) opportunity for teachers in grades K-12 to use astronomy as a vehicle to teach STEM and implement science standards through astronomy. Eight teachers participated in a two-week summer workshop and six follow-up sessions are scheduled during the 2014-2015 school year. Additional teachers plan to participate in the upcoming follow-up sessions. We evaluate the effectiveness of the LASSI PD to identify and confront teachers' misconceptions in astronomy, and discuss whether teachers identified topics for which astronomy can be used as a vehicle for standards-based STEM curricula. Teachers from around Wyoming were invited to participate. Participating teachers were surveyed on the quality of the workshop, their astronomy content knowledge before and after listening to talks given by experts in the field, conducting standards-based inquiry activities, developing their own lessons, and their level of engagement throughout the workshop. Two-thirds of teachers planned to incorporate LASSI activities into their classrooms in this school year. Teachers' misconceptions and requests for astronomy-based curriculum were identified in the summer session. These will be addressed during the follow-up session

Infrared Astronomy

NASA Astrophysics Data System (ADS)

Grygar, J.

2018-04-01

Although infrared radiation was described by W. Herschel already in 1800, technical problems delayed its use in astronomy for 160 years. After the invention of a sensitive bolometer and semiconducting CCD arrays for very wide infrared window the progress in the field accelerated. Many high-altitude observatories started their work in the last three decades of XXth century and since 1983 space observatories became most important due to the fact that infrared radiation penetrates through opaque cold shells. Moreover, cosmological expansion of the Universe shifts the maximum of spectral energy of distant hot objects from ultraviolet to near infrared region. Infrared astronomy is also essential for improving our knowledge of the cold universe, particularly for studies about the birth of stars, planetary systems and galaxies.

Multimedia Astronomy Communication: Effectively Communicate Astronomy to the Desired Audience

NASA Astrophysics Data System (ADS)

Star Cartier, Kimberly Michelle; Wright, Jason

2017-01-01

A fundamental aspect of our jobs as scientists is communicating our work to others. In this, the field of astronomy holds the double-edged sword of ubiquitous fascination: the topic has been of interest to nearly the entire global population at some point in their lives, yet the learning curve is steep within any subfield and rife with difficult-to-synthesize details. Compounding this issue is the ever-expanding array of methods to reach people in today's Communications Era. Each communication medium has its own strengths and weaknesses, is appropriate in different situations, and requires its own specific skillset in order to maximize its functionality. Despite this, little attention is given to training astronomers in effective communication techniques, often relying on newcomers to simply pick up the ability by mimicking others and assuming that a firm grasp on the subject matter will make up for deficiencies in communication theory. This can restrict astronomers to a narrow set of communication methods, harming both the communicators and the audience who may struggle to access the information through those media.Whether writing a research paper to academic peers or giving an astronomy talk to a pubic audience, successfully communicating a scientific message requires more than just an expert grasp on the topic. A communicator must understand the makeup and prior knowledge of the desired audience, be able to break down the salient points of the topic into pieces that audience can digest, select and maximize upon a medium to deliver the message, and frame the message in a way that hooks the audience and compels further interest. In this work we synthesize the requirements of effective astronomy communication into a few key questions that every communicator needs to answer. We then discuss some of the most common media currently used to communicate astronomy, give both effective and poor examples of utilizing these media to communicate astronomy, and provide key

The Core of NGC 6240 from Keck Adaptive Optics and HST NICMOS Observations

2004-06-28

We present results of near infrared imaging of the disk-galaxy-merger NGC 6240 using adaptive optics on the Keck II Telescope and reprocessed archival data from NICMOS on the Hubble Space Telescope. Both the North and South nuclei of NGC 6240 are clearly elongated, with considerable sub-structure within each nucleus. In K' band there are at least two point-sources within the North nucleus; we tentatively identify the south-western point-source within the North nucleus as the position of one of the two AGNs. Within the South nucleus, the northern subnucleus is more highly reddened. Based upon the nuclear separation measured at 5more » GHz, we suggest that the AGN in the South nucleus is still enshrouded in dust at K' band, and is located slightly to the north of the brightest point in K' band. Within the South nucleus there is strong H{sub 2} 1-0 S(1) line emission from the northern sub-nucleus, contrary to the conclusions of previous seeing-limited observations. Narrowband H{sub 2} emission-line images show that a streamer or ribbon of excited molecular hydrogen connects the North and South nuclei. We suggest that this linear feature corresponds to a bridge of gas connecting the two nuclei, as seen in computer simulations of mergers. Many point-like regions are seen around the two nuclei. These are most prominent at 1.1 microns with NICMOS, and in K'-band with Keck adaptive optics. We suggest that these point-sources represent star clusters formed in the course of the merger.« less

Astronomy and Public Policy

Suntzeff, Nicholas B.

2014-01-01

Astronomy is an unusual science in that almost all of what we study can only be passively observed. We enjoy tremendous public support for our research and education, both domestically and abroad. Our discoveries in cosmology and exoplanets have captured world-wide attention, as have stunning images from the Great Observatories of NASA, and ground based telescopes. Despite the passive nature of our science, it touches humanity profoundly. There are groups of amateur astronomers in every conceivable country who meet to look at the sky. Almost one billion people from 150 countries participated in The International Year of Astronomy 2009. No other science reaches humanity as ours does. In a recent poll, it was found that the among all the things the US does abroad, US science is seen by the world as our most positive face. We as astronomers can use this good will to affect positive changes in the world through public policy. I would like to explore how astronomy has impacted public policy, especially foreign policy, and what more we can do in the future. I also hope to encourage astronomers that a career path into public policy is an excellent use of a Ph.D. in astronomy.

Documenting the Vocabulary of Astronomy Communication

NASA Astrophysics Data System (ADS)

Miller, Scott; Parrish, M.; Gay, P. L.

2008-05-01

Learning astronomy can be a life-long process, with the seeds of knowledge planted in K-12 classes blossoming in elective college courses to create adults who actively acquire astronomy content. One of the goals of many astronomy 101 courses is to prepare students to be intelligent consumers of mainstream astronomy content, including magazine articles, popular books, and online news. To meet this goal, astronomy educators need to understand what content is being presented in the media and what level vocabulary is being used. The most simplistic way to address this problem is to examine the topics covered and vocabulary used in mainstream astronomy blogs and news feeds. In this study we looked at a selection of prominent blogs and news feeds and we present a statistical study of the frequency different scientific terms are used and topics are addressed. To make this study possible, software to read in RSS feeds was created. This software had to meet the following design specifications: runs in a reasonable amount of time, removes all XML and HTML code from text, sees words with different capitalizations as the same word, ignores end of sentence or phrase punctuation without ignoring hyphens, and has an editable list of "common English words.” This code will be available after the conference at http://www.starstryder.com. Results of this study find that many of the primary topics of Astronomy 101 classes, such as the HR Diagram, are rarely mentioned in blogs and online news, while often de-emphasized topics, such as extra solar planets, cosmology, and high energy astrophysics, show up regularly.

Archaeo- and Cultural Astronomy in Armenia

Farmanyan, Sona V.; Mickaelian, Areg M.

2015-08-01

We present a general overview on Armenian Archaeoastronomy and Astronomy in Culture to mention and summarize some activities and related organizations involved. Armenia is rather rich in archaeoastronomy and culture, including calendars, rock art, mythology, etc. Archaeoastronomical issues in Armenia include: Zodiac Constellations (believed to be introduced for the first time in the Armenian Highland); Ancient Observatories; Armenian Rock Art; Ancient Armenian Calendar and other (medieval) calendars; Astronomical Terms and Names; Records of Astronomical Events by ancient Armenians; Anania Shirakatsi’s (612-685) Astronomical Heritage; Medieval Sky Maps and Astronomical Devices. During the recent years, we have organized a number of meetings, where archaeoastronomy was involved: Joint European and National Astronomy Meeting (JENAM-2007), Special Session #6: “Archaeoastronomy” (2007), ArAS VIII Annual Meeting “Astronomy and Society”, Session “Archaeoastronomy” (2009), Archaeoastronomical meeting “Astronomical Heritage in the National Culture” dedicated to Anania Shirakatsi’s 1400th anniversary (2012), Meeting “Relation of Astronomy to other Sciences, Culture and Society” (RASCS), Sessions“Archaeoastronomy” and “Astronomy in Culture” (2014). Along with Byurakan Astrophysical Observatory (BAO), there are several other institutions related to Archaeoastronomy and Astronomy in Culture: Institute of History, Institute of Archaeology and Ethnography, Institute of Literature, Institute of Language, Matenadaran (Institute of Ancient Manuscripts). We have introduced a section “Archaeoastronomy and Astronomy in Culture” in the newsletter of Armenian Astronomical Society (ArAS). This is to strengthen ArAS activities and to widen our knowledge in this area, to encourage and establish collaborations with other scientists related to these subjects; historians, archaeologists, ethnographers, philologists, linguists, artists and other

How, precisely, can astronomy be of benefit to anyone?

NASA Astrophysics Data System (ADS)

Jones, Bernard J. T.

2011-06-01

Astronomy as an observational science is technology driven both from the point of view of data acquisition and of data processing and visualisation. Astronomy exploits a very wide base of technologies which are developed, enhanced and extended by users. Consequently, astronomy can return new and enhanced technologies to areas well outside of astronomy itself. My own hi-tech company, Astraguard, a video imaging company, is a small but significant example of that technology return. Astronomy can provide both know-how and people for a diverse variety of areas: security, industrial process control, medical and biological imaging, petrochemicals, databases, and the financial industries to name but a few. It is unfortunate that those who teach astronomy are generally not aware of these possibilities. In this lecture I hope to take a first step towards showing what is possible. I hope to convince the reader that astronomy education, at all levels, can play a significant role in career development outside of astronomy and in higher education in developing countries.

The Flying Telescope: How to Reach Remote Areas in the Colombian Andes for Astronomy Outreach

NASA Astrophysics Data System (ADS)

Seidel, M. K.; Buelhoff, K.

2016-12-01

The project Cielo y Tierra, Spanish for Sky and Earth, was undertaken in order to bring astronomy and ecology to remote villages throughout Colombia using sustainable transport. This transport included three horses and two paragliders. The innovative approach of the expedition helped to keep an extremely low budget whilst making it possible to cross the Colombian Andes from northeast to southwest. This article will show how projects like these can succeed, the need for this kind of project, and the possible impact, with this project reaching more than 1500 people. We hope to encourage others not to be afraid of going into countries like Colombia on a low-budget educational expedition. The success of this project shows that outreach and education projects are possible in these remote areas where little or no governmental or other support reaches.

Social Astronomy: Cooperating with Local Community Networks

Bará, S.

2009-11-01

When the IYA2009 Canada Committee, chaired by Jim Hesser, first came together, it established a vision: "to offer an engaging astronomy experience to every person in Canada, and to cultivate partnerships that sustain public interest in astronomy". We called the engaging astronomy experience a "Galileo Moment". We knew that a Galileo Moment could be a first look through a telescope at the Moon, Jupiter or Saturn. But we especially wanted to connect with new audiences, not just the same people who always came to astronomy events. So we knew that a Galileo Moment could equally well be the intellectual or emotional effect of an astronomy-inspired piece of art or music. So far in 2009, over 10 000 Canadians have experienced a Galileo Moment of the latter kind, thanks to the Tafelmusik Baroque Orchestra's The Galileo Project.

We introduce the Keck OSIRIS Nearby AGN survey (KONA), a new adaptive optics-assisted integral-field spectroscopic survey of Seyfert galaxies. KONA permits at ∼0.″1 resolution a detailed study of the nuclear kinematic structure of gas and stars in a representative sample of 40 local bona fide active galactic nucleus (AGN). KONA seeks to characterize the physical processes responsible for the coevolution of supermassive black holes and galaxies, principally inflows and outflows. With these IFU data of the nuclear regions of 40 Seyfert galaxies, the KONA survey will be able to study, for the first time, a number of key topics with meaningful statistics. In this paper we study the nuclear K-band properties of nearby AGN. We find that the K-band (2.1 μm) luminosities of the compact Seyfert 1 nuclei are correlated with the hard X-ray luminosities, implying a non-stellar origin for the majority of the continuum emission. The best-fit correlation is log L K = 0.9log L 2–10 keV + 4 over three orders of magnitude in both K-band and X-ray luminosities. We find no strong correlation between 2.1 μm luminosity and hard X-ray luminosity for the Seyfert 2 galaxies. The spatial extent and spectral slope of the Seyfert 2 galaxies indicate the presence of nuclear star formation and attenuating material (gas and dust), which in some cases is compact and in some galaxies extended. We detect coronal-line emission in 36 galaxies and for the first time in 5 galaxies. Finally, we find 4/20 galaxies that are usually classified as Seyfert 2 based on their optical spectra exhibit a broad component of Brγ emission, and one galaxy (NGC 7465) shows evidence of a double nucleus.

The observatory was made possible by the generous financial support of the W. M

Editorial: What Use Is Astronomy?

NASA Astrophysics Data System (ADS)

Percy, J. R.

Why do people such as AAVSOers observe or analyze variable stars? A few readers may simply say that observing is a relaxing, outdoor pastime, like fishing, and that analysis is a way to keep the mind occupied, like solitaire. But most will say "to advance the science of astronomy." But what use is astronomy?

El Fady Beshara Morcos, Abd

2015-08-01

One of the major challenges in Egypt is the quality of education. Egypt has made significant progress towards achieving the Education for All and the Millennium Development Goals (MDGs). Many associations and committees as education reform program and education support programs did high efforts in supporting scientific thinking through the scientific clubs. The current state of astronomical education in Egypt has been developed. Astronomy became a part in both science and geography courses of primary, preparatory and secondary stages. Nowadays the Egyptian National Committee for Astronomy, put on its shoulders the responsibility of revising of astronomy parts in the education courses, beside preparation of some training programs for teachers of different stages of educations, in collaboration with ministry of education. General lectures program has been prepared and started in public places , schools and universities. Many TV and Radio programs aiming to spread astronomical culture were presented. In the university stage new astronomy departments are established and astrophysics courses are imbedded in physics courses even in some private universities.

Deep Keck u-Band Imaging of the Hubble Ultra Deep Field: A Catalog of z ~ 3 Lyman Break Galaxies

Rafelski, Marc; Wolfe, Arthur M.; Cooke, Jeff; Chen, Hsiao-Wen; Armandroff, Taft E.; Wirth, Gregory D.

2009-10-01

We present a sample of 407 z ~ 3 Lyman break galaxies (LBGs) to a limiting isophotal u-band magnitude of 27.6 mag in the Hubble Ultra Deep Field. The LBGs are selected using a combination of photometric redshifts and the u-band drop-out technique enabled by the introduction of an extremely deep u-band image obtained with the Keck I telescope and the blue channel of the Low Resolution Imaging Spectrometer. The Keck u-band image, totaling 9 hr of integration time, has a 1σ depth of 30.7 mag arcsec-2, making it one of the most sensitive u-band images ever obtained. The u-band image also substantially improves the accuracy of photometric redshift measurements of ~50% of the z ~ 3 LBGs, significantly reducing the traditional degeneracy of colors between z ~ 3 and z ~ 0.2 galaxies. This sample provides the most sensitive, high-resolution multi-filter imaging of reliably identified z ~ 3 LBGs for morphological studies of galaxy formation and evolution and the star formation efficiency of gas at high redshift.

Dispelling superstitions in Nepalese society with astronomy

NASA Astrophysics Data System (ADS)

Shah, Rishi

2011-06-01

Throughout human history, astronomy has played crucial rôle in the development of our civilization, culture and daily chores of lives that have been influenced by observations of Sun, moon, planets, stars and other cosmic entities. Our ancestors who were hunting and gathering and foraging food while living in caves learned to think logically by gazing at the twinkling stars in the heavens. Seasons for crops plantation were determined, time concept was introduced, entire sky was charted and the motions of celestial objects were meaningfully understood. With the advent of telescopes, the geocentric model of universe was replaced by the revolutionary heliocentric concept of our Solar System. Astronomy dispelled superstitious beliefs strongly prevailing in societies. Closely associated with numerous disciplines of science astronomy is still flourishing worldwide and is attempting to fly us away to those habitable cosmic bodies of our universe. By establishing well-equipped observational infrastructure local and international astronomy research and development could be enhanced. Introduction of astronomy in education system right from school would attract and encourage students to pursue higher studies for enabling them for participating in future international scientific and exploration programmes. Astronomy has helped our society to progress peacefully and efficiently.

Astronomy Outreach for Large and Unique Audiences

Lubowich, D.; Sparks, R. T.; Pompea, S. M.; Kendall, J. S.; Dugan, C.

2013-04-01

In this session, we discuss different approaches to reaching large audiences. In addition to star parties and astronomy events, the audiences for some of the events include music concerts or festivals, sick children and their families, minority communities, American Indian reservations, and tourist sites such as the National Mall. The goal is to bring science directly to the public—to people who attend astronomy events and to people who do not come to star parties, science museums, or science festivals. These programs allow the entire community to participate in astronomy activities to enhance the public appreciation of science. These programs attract large enthusiastic crowds often with young children participating in these family learning experiences. The public will become more informed, educated, and inspired about astronomy and will also be provided with information that will allow them to continue to learn after this outreach activity. Large and unique audiences often have common problems, and their solutions and the lessons learned will be presented. Interaction with the participants in this session will provide important community feedback used to improve astronomy outreach for large and unique audiences. New ways to expand astronomy outreach to new large audiences will be discussed.

Keck Deep Fields. I. Observations, Reductions, and the Selection of Faint Star-forming Galaxies at Redshifts z ~ 4, 3, and 2

NASA Astrophysics Data System (ADS)

Sawicki, Marcin; Thompson, David

2005-12-01

We introduce a very deep, Rlim~27, multicolor imaging survey of very faint star-forming galaxies at z~4, 3, 2.2, and 1.7. This survey, carried out on the Keck I telescope, uses the very same UnGRI filter system that is employed by the Steidel team to select galaxies at these redshifts and thus allows us to construct identically selected but much fainter samples. However, our survey reaches ~1.5 mag deeper than the work of Steidel and his group, letting us probe substantially below the characteristic luminosity L* and thus study the properties and redshift evolution of the faint component of the high-z galaxy population. The survey covers 169 arcmin2 in three spatially independent patches on the sky and-to R<=27-contains 427 GRI-selected z~4 Lyman break galaxies, 1481 UnGR-selected z~3 Lyman break galaxies, 2417 UnGR-selected z~2.2 star-forming galaxies, and 2043 UnGR-selected z~1.7 star-forming galaxies. In this paper, the first in a series, we introduce the survey, describe our observing and data reduction strategies, and outline the selection of our z~4, 3, 2.2, and 1.7 samples. Based on data obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation.

Astronomy Teaching Problems in Armenia

NASA Astrophysics Data System (ADS)

Gyulzadyan, M. V.

2015-07-01

Astronomy, like any science, constantly develops unlimitedly approaching absolute objective truth; every moment of its accomplishments are due to the level of public welfare demands and culture. Armenia for centuries had a major contributor to the ancient as well as to the modern astronomy development. But it has been already a couple of years that the "Astronomy" course is not present at the schools of Armenia. Despite that fact, several schools put an effort to stress the importance of that subject by extracurricular groups trying to fill that gap. How this work is carried out and what results do we have? What can be done to increase the level of astronomical education as well as for its expansion?

2015-08-01

This study presents results of a survey conducted at the Federal Institution of Education, Science and Technology in the North of Minas Gerais (IFNMG), and aimed to investigate the potentialities of the use of interactive materials in the teaching of astronomy. An advanced training course with involved learning activities about basic concepts of astronomy was offered to thirty-two Licenciate students in Physics, Mathematics and Biological Sciences, using the mixed methodology, combined with the three pedagogical moments. Among other aspects, the viability of the use of resources was noticed, involving digital technologies and interactive materials on teaching of astronomy, which may contribute to the broadening of methodological options for future teachers and meet their training needs.

Exploring Metacogntive Visual Literacy Tasks for Teaching Astronomy

NASA Astrophysics Data System (ADS)

Slater, Timothy F.; Slater, S.; Dwyer, W.

2010-01-01

Undoubtedly, astronomy is a scientific enterprise which often results in colorful and inspirational images of the cosmos that naturally capture our attention. Students encountering astronomy in the college classroom are often bombarded with images, movies, simulations, conceptual cartoons, graphs, and charts intended to convey the substance and technological advancement inherent in astronomy. For students who self-identify themselves as visual learners, this aspect can make the science of astronomy come alive. For students who naturally attend to visual aesthetics, this aspect can make astronomy seem relevant. In other words, the visual nature that accompanies much of the scientific realm of astronomy has the ability to connect a wide range of students to science, not just those few who have great abilities and inclinations toward the mathematical analysis world. Indeed, this is fortunate for teachers of astronomy, who actively try to find ways to connect and build astronomical understanding with a broad range of student interests, motivations, and abilities. In the context of learning science, metacognition describes students’ self-monitoring, -regulation, and -awareness when thinking about learning. As such, metacognition is one of the foundational pillars supporting what we know about how people learn. Yet, the astronomy teaching and learning community knows very little about how to operationalize and support students’ metacognition in the classroom. In response, the Conceptual Astronomy, Physics and Earth sciences Research (CAPER) Team is developing and pilot-testing metacogntive tasks in the context of astronomy that focus on visual literacy of astronomical phenomena. In the initial versions, students are presented with a scientifically inaccurate narrative supposedly describing visual information, including images and graphical information, and asked to assess and correct the narrative, in the form of peer evaluation. To guide student thinking, students

Boltuch, D.; Hund, L.; Buck, S.; Fultz, C.; Smith, T.; Harris, R.; Castelaz, M. W.; Moffett, D.; LaFratta, M.; Walsh, L.

2005-12-01

We present elements of a curriculum that will accompany the STARLAB module "Sensing the Radio Sky" a portable planetarium program and projection of the radio sky. The curriculum will serve to familiarize high school students to a set of topics in radio astronomy. The curriculum includes lessons and activities addressing several topics related to radio astronomy and the Milky Way that consists of two main resources: a manual and a multimedia website. It is designed to accommodate a wide variety of possible uses and time constraints. The manufacturer of STARLAB, Learning Technologies, Inc. produces a short manual to accompany each presentation for the STARLAB. The "Sensing the Radio Sky" manual we have created includes the mandatory, minimum background information that students need to understand radio astronomy. It briefly discusses waves and electromagnetic radiation, similarities and differences between optical and radio astronomy, probable misconceptions about radio astronomy, how radio images are produced, synchrotron radiation in the Milky Way, and galactic coordinates. It also includes a script that presenters can choose to follow inside the STARLAB, a lesson plan for teachers, and activities for students to complete before and after the STARLAB experience that mirror the scientific method. The multimedia website includes more detailed information about electromagnetic radiation and a more detailed comparison of optical and radio astronomy. It also discusses the life cycles of stars, radiation from a variety of specific sources, and pulsars, as each relates to radio astronomy. The five highly detailed lessons are pulled together in sixth "overview lesson", intended for use by teachers who want to present more than the basic material in the manual, but do not have the classroom time to teach all five of the in-depth lessons. . We acknowledge support from the NSF Internship in Public Science Education Program grant number 0324729.

What next for astronomy?

NASA Astrophysics Data System (ADS)

Williams, Robert

2009-12-01

"Astronomy is in the midst of a golden age," wrote Catherine Cesarsky, my predecessor as president of the International Astronomical Union (IAU), earlier this year in Physics World (March pp22-24). I believe that is certainly true and it is an opportunity that we must take full advantage of. Astronomy is one of the great ways to bring science to the public - the images of the universe obtained using the Hubble Space Telescope, for example, are full of beauty. Astronomy is all about us. Indeed, the Earth and the life on it have developed from the cosmos, and the sky is the one laboratory that all humanity shares equally and that is accessible to all. There is little about the subject that appeals to fear - except, perhaps, the occasional killer asteroid. So what better science to inspire and educate people that what we do not know is definitely worth knowing?

Strategies for Teaching Astronomy

NASA Astrophysics Data System (ADS)

Bennett, J.

2000-12-01

No matter whether you are teaching school children, undergraduates, or colleagues, a few key strategies are always useful. I will present and give examples for the following five key strategies for teaching astronomy. 1. Provide a Contextual Framework: It is much easier to learn new facts or concepts if they can be ``binned" into some kind of pre-existing mental framework. Unless your listeners are already familiar with the basic ideas of modern astronomy (such as the hierarchy of structure in the universe, the scale of the universe, and the origin of the universe), you must provide this before going into the details of how we've developed this modern picture through history. 2. Create Conditions for Conceptual Change: Many people hold misconceptions about astronomical ideas. Therefore we cannot teach them the correct ideas unless we first help them unlearn their prior misconceptions. 3. Make the Material Relevant: It's human nature to be more interested in subjects that seem relevant to our lives. Therefore we must always show students the many connections between astronomy and their personal concerns, such as emphasizing how we are ``star stuff" (in the words of Carl Sagan), how studying other planets helps us understand our own, and so on. 4. Limit Use of Jargon: The number of new terms in many introductory astronomy books is larger than the number of words taught in many first courses in foreign language. This means the books are essentially teaching astronomy in a foreign language, which is a clear recipe for failure. We must find ways to replace jargon with plain language. 5. Challenge Your Students: Don't dumb your teaching down; by and large, students will rise to meet your expectations, as long as you follow the other strategies and practice good teaching.

Hemphill, Rosa; Blackwell, J. A.; Herrold, A.; Petroff, E.

2007-12-01

We present education and outreach results using our experiences involving the Spitzer Space Telescope project, Star Formation in High Redshift Clusters with Spitzer. The project is a collaboration between the Spitzer Science Center and the National Optical Astronomy Observatory. Using the Spitzer Space Telescope, we measured star formation rates in three galaxy clusters at intermediate redshifts. Six teachers were chosen for the program, each with an interest and involvement in astronomy education. From this project, lesson plans, public outreach, lectures and demonstrations were generated which better the understanding of infrared astronomy, multiwavelength astronomy, galaxy and star formation, and cosmology. The teacher mentors are Dr. Gregory Rudnick (NOAO), Dr. Rose Finn (Siena College), and Dr. Vandana Desai (Caltech). Please see the companion posters by Emily Petroff, Zak Schroeder, and Thomas Loughran, et al, for information concerning the science results.

Making Space for Specialized Astronomy Resources

NASA Astrophysics Data System (ADS)

MacMillan, D.

2007-10-01

With the growth of both free and subscription-based resources, articles on astronomy have never been easier to find. Locating the best and most current materials for any given search, however, now requires multiple tools and strategies dependent on the query. An analysis of the tools currently available shows that while astronomy is well-served by Google Scholar, Scopus and Inspec, its literature is best accessed through specialized resources such as ADS (Astrophysics Data System). While no surprise to astronomers, this has major implications for those of us who teach information literacy skills to astronomy students and work in academic settings where astronomy is just one of many subjects for which our non-specialist colleagues at the reference desk provide assistance. This paper will examine some of the implications of this analysis for library instruction, reference assistance and training, and library webpage development.

Developing Astronomy Research and Education in the Philippines

NASA Astrophysics Data System (ADS)

Sese, R. M. D.; Kouwenhoven, M. B. N. Thijs

2015-03-01

In the past few years, the Philippines has been gradually developing its research and educational capabilities in astronomy and astrophysics. In terms of astronomy development, it is still lagging behind several neighboring Southeast Asian countries such as Indonesia, Thailand and Malaysia, while it is advanced with respect to several others. One of the main issues hampering progress is the scarcity of trained professional Filipino astronomers, as well as long-term visions for astronomy development. Here, we will be presenting an overview of astronomy education and research in the country. We will discuss the history and current status of astronomy in the Philippines, including all levels of education, outreach and awareness activities, as well as potential areas for research and collaborations. We also discuss issues that need to be addressed to ensure sustainable astronomy development in the Philippines. Finally, we discuss several ongoing and future programs aimed at promoting astronomy research and education. In essence, the work is a precursor of a possible white paper which we envision to submit to the Department of Science and Technology (DOST) in the near future, with which we aim to further convince the authorities of the importance of astrophysics. With the support of the International Astronomical Union (IAU), this may eventually lead to the creation of a separate astronomy agency in the Philippines.

2011 Astronomy Day at McDonald Observatory

NASA Astrophysics Data System (ADS)

Preston, Sandra; Hemeway, M.; Wetzel, M.

2012-01-01

Our philosophy is that everyday is Astronomy Day because the McDonald Observatory's Frank N. Bash Visitors Center is open 362 days a year. So, how did we create a special celebration for the "Astronomy Day” declared by the Astronomical League? During September 26-29 we conducted 20 videoconferences and served 12,559 students with "Astronomy Day” programming. Connect2Texas provides bridging for a network of Texas-based museums and cultural, historical, and scientific organizations that offer educational content to schools throughout the state via videoconferencing. Connect2Texas connected McDonald Observatory to 334 schools; most of these schools were in Texas, but schools in a dozen other states also participated. While most schools had a "view-only" connection, at least 20 of the schools had interactive connections, whereby the students could ask questions of the presenter. Connect2Texas also collects evaluation information from the participating schools that we will use to produce a report for our funders and make modifications to future programs as need be. The videoconferences were offered free of charge. The theme for the 2011 Astronomy Day program was the Year of the Solar System, which aligns with NASA's theme for 2011 and 2012. By aligning with this NASA theme, we could leverage NASA artwork and materials to both advertise and enrich the learning experience. Videoconference materials also included pre- and post-videoconference assessment sheets, an inquiry based activity, and pre- and post-videoconference activities, all of which were made available online. One of the lessons learned from past Astronomy Day videoconferences is that the days the Astronomical League declares as "Astronomy Day” are not always good days for Texas schools to participate. So, we choose an Astronomy Day that meets the needs of Texas schools and our schedule - so any day can be Astronomy Day. 2011 Astronomy Day was made possible by The Meyer-Levy Charitable Trust.

Astronomy in the Service of Islam

NASA Astrophysics Data System (ADS)

King, David A.

In their assessment of Islamic astronomy, historians have usually been concerned only with that part of the Muslim scientific heritage that was transmitted to the West in the Middle Ages. Yet most Islamic works on astronomy were not transmitted to the West, and they are known today mainly due to the work of orientalists in the nineteenth and twentieth centuries. This is the case of Muslim writings on three aspects of mathematical science that were closely linked with religious observance. This is an overview of those "Islamic aspects of Islamic astronomy".

Macêdo, J. A.; Voelzke, M. R.

2014-10-01

This study presents results of a survey conducted at the Federal Institution of Education, Science and Technology in the North of Minas Gerais (IFNMG), and aimed to investigate the potentialities of the use of interactive materials in the teaching of astronomy. An advanced training course with involved learning activities about basic concepts of astronomy was offered to thirty-two Licenciate students in Physics, Mathematics and Biological Science. The following steps were to be taken: i) analysis of the pedagogical projects (PPC) of the licenciates at the IFNMG, research locus of its Campus Januária; ii) analysis of students' preconceptions about astronomy and digital technologies, identified by the application of an initial questionnaire; iii) preparation of the course taking into account the students' previous knowledge; iv) application of the education proposal developed under part-time presence modality, using various interactive tools; v) application and analysis of the final questionnaire. The test was conducted with the qualitative and quantitative methodology, combined with a content analysis. The results indicated that in the IFNMG only the licenciate-course in physics includes astronomy content diluted in various subjects of the curriculum; the rates of students prior knowledge in relation to astronomy was low; an evidence of meaningful learning of the concepts related to astronomy, and of viability of resource use involving digital technologies in the Teaching of astronomy, which may contribute to the broadening of methodological options of future teachers and meet their training needs.

Keck spectroscopy of millisecond pulsar J2215+5135: a moderate-M

We present Keck spectroscopic measurements of the millisecond pulsar binary J2215+5135. These data indicate a neutron-star (NS) massmore » $${M}_{\\mathrm{NS}}=1.6\\;{M}_{\\odot }$$, much less than previously estimated. The pulsar heats the companion face to $${T}_{D}\\approx 9000$$ K; the large heating efficiency may be mediated by the intrabinary shock dominating the X-ray light curve. At the best-fit inclination i = 88 $$^o\\atop{.}$$ 8, the pulsar should be eclipsed. Here, we find weak evidence for such eclipses in the pulsed gamma-rays; an improved radio ephemeris allows use of up to five times more Fermi-Large Area Telescope gamma-ray photons for a definitive test of this picture. If confirmed, the gamma-ray eclipse provides a novel probe of the dense companion wind and the pulsar magnetosphere.« less

Cultural Astronomy in Armenia and in the World

NASA Astrophysics Data System (ADS)

Farmanyan, S. V.; Mickaelian, A. M.

2016-12-01

Cultural Astronomy is the reflection of sky events in various fields of nations' culture. In foreign literature, this field is also called "Astronomy in Culture" or "Astronomy and Culture". Cultural astronomy is the set of interdisciplinary fields studying the astronomical systems of current or ancient societies and cultures. It is manifested in Religion, Mythology, Folklore, Poetry, Art, Linguistics and other fields. In recent years, considerable attention has been paid to this sphere, particularly international organizations were established, conferences are held and journals are published. Armenia is also rich in cultural astronomy. The present paper focuses on Armenian archaeoastronomy and cultural astronomy, including many creations related to astronomical knowledge; calendars, rock art, mythology, etc. On the other hand, this subject is rather poorly developed in Armenia; there are only individual studies on various related issues (especially many studies related to Anania Shirakatsi) but not coordinated actions to manage this important field of investigation.

Communicating astronomy with the public to produce attractive materials for a broad audience on TV is a difficult job in a third world country. One way of developing effective communication in fields like astronomy, astrophysics, and cosmology whilst connecting the professional astronomer with a majority of the people is to combine the knowledge of the scientist with the most spectacular TV production methods of first world countries: integrating, through commentary and analysis, astronomy and science into the public debate of lay citizens. Here I present my ten years of experience of presenting a TV programme devoted to general science outreach. I also comment on the progress of the construction of the new planetarium, a cultural centre for science and technology, to be opened as part of the commemoration activities for the 2009 International Year of Astronomy. It is hoped to guide the interest of the people of Cuba towards basic science and astronomy in the most populated and frequented area of the country.

Astronomers Without Borders: A Global Astronomy Community

Simmons, M.

2011-10-01

Astronomers Without Borders (AWB) brings together astronomy enthusiasts of all types - amateur astronomers, educators, professionals and "armchair" astronomers for a variety of online and physicalworld programs. The AWB web site provides social networking and a base for online programs that engage people worldwide in astronomy activities that transcend geopolitical and cultural borders. There is universal interest in astronomy, which has been present in all cultures throughout recorded history. Astronomy is also among the most accessible of sciences with the natural laboratory of the sky being available to people worldwide. There are few other interests for which people widely separated geographically can engage in activities involving the same objects. AWB builds on those advantages to bring people together. AWB also provides a platform where projects can reach a global audience. AWB also provides unique opportunities for multidisciplinary collaboration in EPO programs. Several programs including The World at Night, Global Astronomy Month and others will be described along with lessons learned.

Humanising Astronomy

NASA Astrophysics Data System (ADS)

Levin, S.

2008-06-01

Universe Awareness (UNAWE) is an international programme that aims to expose underprivileged children (in the age group 4-10) to the inspirational aspects of astronomy. We are currently at the stage of developing materials that will be utilised in a diverse range of environments. This paper explores UNAWE's particular approach to developing tools which includes not only indigenous and folkloric astronomical knowledge, but also the culture of transmission of such knowledge. A specific understanding and explanation of the Universe, the Sun, Moon and stars is present in every culture and can be found contained in its history, legends and belief systems. By consciously embracing different ways of knowing the Universe and not uniquely the rational model, UNAWE places the humanising potential of astronomy at the centre of its purpose. Whilst inspiring curiosity, pride and a sense of ownership in one's own cultural identity, such an approach also exposes children to the diversity of other peoples and their cultures as well as the unifying aspects of our common scientific heritage. The means of creating and delivering the astronomy programme are as relevant to the desired educational outcomes as the content. The challenge in the design of materials is to communicate this stimulating message to the very young. Respect for alternative values systems, the need for dialogue and community participation, and where possible the production of materials using local resources is emphasised. This paper touches recent experiences liaising with communities in India, South Africa, Tunisia, Venezuela and Colombia.

Highlighting the History of French Radio Astronomy. 7: The Genesis of the Institute of Astronomy at Millimeter Wavelengths (IRAM)

NASA Astrophysics Data System (ADS)

Encrenaz, Pierre; Gómez González, Jesús; Lequeux, James; Orchiston, Wayne

2011-07-01

Radio astronomy in France and in Germany started around 1950. France was then building interferometers and Germany large single dishes, so it was not unexpected that their first projects involving millimetre radio astronomy were respectively with an interferometer and a single dish. In this paper, we explain in detail how these two projects finally merged in 1979 with the formation of the Institute of Radio Astronomy at Millimetre Wavelengths (IRAM), after a long process with many ups and downs. We also describe how Spain started radio astronomy by joining IRAM. Presently, IRAM is the most powerful facility worldwide for millimetre radio astronomy. We wish to dedicate our paper to the memory of Émile-Jacques Blum (1923-2009), who played a major role in the construction of IRAM but died before he could participate in the writing of this paper. An interview made one month before his death was very useful in the preparation of this paper.

Methodological pluralism in the teaching of Astronomy

de Macedo, Josué Antunes; Voelzke, Marcos Rincon

2015-04-01

This paper discusses the feasibility of using a teaching strategy called methodological pluralism, consisting of the use of various methodological resources in order to provide a meaningful learning. It is part of a doctoral thesis, which aims to investigate contributions to the use of traditional resources combined with digital technologies, in order to create autonomy for future teachers of Natural Sciences and Mathematics in relation to themes in Astronomy. It was offered an extension course at the "Federal Institution of Education, Science and Technology" in the North of Minas Gerais (FINMG), Campus Januaria, for thirty-two students of licentiate courses in Physics, Mathematics and Biological Sciences, involving themes of Astronomy, in order to search and contribute to improving the training of future teachers. The following aspects are used: the mixed methodology, with pre-experimental design, combined with content analysis. The results indicate the rates of students' prior knowledge in relation to Astronomy was low; meaningful learning indications of concepts related to Astronomy, and the feasibility of using digital resources Involving technologies, articulated with traditional materials in the teaching of Astronomy. This research sought to contribute to the initial teacher training, especially in relation to Astronomy Teaching, proposing new alternatives to promote the teaching of this area of knowledge, extending the methodological options of future teachers.

1996-11-01

World's Biggest Astronomy WWW-Event Attracts Thousands of Students The Astronomy On-line Programme (See ESO Press Release 09/96 of 18 June 1996) began officially on 1 October and is now about to enter its most intense phase, known as the Hot Week . On 18 - 22 November, an estimated 4000 astronomy-interested, mostly young people in Europe and on four other continents will get together during five days in what - not unexpected - has become the world's biggest astronomy event ever organised on the World Wide Web. This carefully structured Programme is carried out in collaboration between the European Association for Astronomy Education (EAAE), the European Southern Observatory and the European Commission, under the auspices of the Fourth European Week for Scientific and Technological Culture. The Programme has already had a most visible impact on the school education of natural sciences in various countries; for instance, the Internet-connection of schools has been advanced in some, in order to allow groups to participate. There have been numerous contacts among the groups across the borders and there are clear signs that many Astronomy On-line participants have progressed to use the impressive possibilities of the Web in an efficient and structured way. There has been a lively media interest in Astronomy On-line all over Europe and it is expected to increase during the next week. The current status of Astronomy On-line It is obvious that the pilot function of the Astronomy On-line Programme in the use of the Web has been very effective and that the associated dissemination of astronomical knowledge has been successful. At this time, more than 650 groups have registered with Astronomy On-line. Most come from 31 different European countries and a few dozen groups are located in North and South America as well as in Asia and Australia. Together they have experienced the steady build-up of Astronomy On-line over the past weeks, by means of numerous contributions from a

2014-01-01

The Network for Astronomy School Education Project (NASE) was developed in response to the IAU's most recent 10 Years Strategic Plan to increase the efforts of the IAU in schools. NASE's mission is to stimulate teaching astronomy in schools, through professional development of primary and secondary school science teachers in developing and emerging countries. NASE's organizational principle is to build capacity by providing courses for three years in cooperation with a Local Organizing Committee (Local NASE Group). The Local NASE Group consists of 6-8 local university professors and education professional who will promote astronomy activities and organize future courses in subsequent years in their region of their country. NASE philosophy is to introduce low-tech astronomy, and has thus developed an a suite of activities that can be carried out with inexpensive, quotidian materials. Supporting these activities is a text for teachers, plus a complete set of instructional materials for each topic. These materials are available in English and Spanish, with future editions available in Chinese and Portuguese. We describe and discuss NASE activities in Central and South America from 2009 to the present.

Rees, Shannon; Maldonado, M.; Beasley, D.; Campos, A.; Medina, A.; Chanover, N. J.

2014-01-01

The Society of Astronomy Students (SAS) at New Mexico State University (NMSU) was founded in October of 2012 and chartered in January 2013. New Mexico State University is located in Las Cruces, New Mexico, which is a small city with a population of just over 100,000. The main campus at NMSU has an enrollment of approximately 14,300 undergraduate students and 3,375 graduate students. The NMSU Astronomy Department is a vibrant research environment that offers Ph.D. and M.S. Graduate degrees and serves the undergraduate population through a large number of general education courses. Although there is no undergraduate major in Astronomy at NMSU, students can earn an undergraduate Astronomy Minor. The SAS was conceived as a way to provide undergraduates with an interest in astronomy a way to communicate, network, and provide mutual support. Currently, the SAS is in its second year of being a chartered organization and has about 18 active members, about half of whom are planning on pursuing an Astronomy Minor. The SAS is striving to become one of the most active clubs on the NMSU campus in order to raise awareness about Astronomy and encourage the option of pursuing the Astronomy Minor. One of the main focus areas of the SAS is to be involved in both astronomy-related and non-astronomy-related public outreach and community service events. Since the clubs inception, the SAS members have contributed a total of over 120 volunteer hours. We do many outreach events with the elementary and middle schools around the community; these events are done jointly with the Astronomy Graduate Student Organization at NMSU. In the near future, the SAS is also planning a wide range of activities, including a guest speaker series at weekly club meetings, tours of the Apache Point Observatory, full moon outings, and participation in amateur astronomy events such as the Messier Marathon. This presentation will include an overview of the club's history, accomplishments, and future activities.

Most students entering our introductory astronomy course for nonscience majors arrive not merely lacking scientific facts-they also have misconceptions about the nature of science, and many have a handicapping ``science anxiety'' (in addition to math anxiety). So I have added a ``current science'' requirement to our introductory course. Each student must compile a file of five astronomy news articles taken from readily available sources.

Miley, George

2012-08-01

Astronomy is a unique tool for international development because it combines cutting-edge technology with fundamental science and has deep cultural roots. The International Astronomical Union regards furthering the exploitation of astronomy for sustainable global development as an important part of its mission.To realize these aspirations the IAU has developed an ambitious strategic plan for the period 2010-2020. This plan, "Astronomy for the developing world: Building from IYA 2009", endorsed by the IAU General Assembly in 2009, envisages a substantial increase in IAU educational and development activities during the next decade. This article will discuss the content of the plan, the processes that led to its creation and adoption and the setting up of the IAU Global Office of Astronomy for Development at the SAAO in Cape Town, South Africa. We shall also describe the activities envisaged in the plan and argue that such a program is important for its own sake and necessary to generate funding for the next generation of astronomical research facilities.

“Astronomy for a Better World”: IAU/OAD Task Force One Activities to Develop Astronomy Education and Research at Universities in the Developing World

NASA Astrophysics Data System (ADS)

Guinan, Edward Francis; Kolenberg, Katrien

2015-08-01

The Task Force (1) on Astronomy for Universities & Research (TF-1) was established in 2012 as part of the IAU Office of Astronomy for Development (OAD). This Task Force drives activities related to astronomy education and research at universities mainly in the developing world. Astronomy is used to stimulate research and education in STEM fields and to develop and promote astronomy in regions of the world where there is little or no astronomy. There is also potential for developing research in the historical and cultural aspects of astronomy which may prove important for stimulating an interest in the subject in communities where there is yet no established interest in the science.Since the establishment of the OAD, over 25 TF-1 programs have been funded (or partially funded) to support a wide variety of interesting and innovative astronomy programs in Africa, Asia, South-East Asia, Middle-East, and in South & Central America. Nearly every aspect of development has been supported. These programs include supporting: regional astronomy training schools, specialized workshops, research visits, university twinning programs, distance learning projects, university astronomy curriculum development, as well as small telescope and equipment grants. In addition, a large new program - Astrolab - was introduced (by J-P De Greve and Michele Gerbaldi) to bring starlight” into the class room. In the Astrolab program students carry out and reduce CCD photometry secured by them using remotely controlled telescopes. Results from pilot programs will be discussed.OAD TF-1 programs will be discussed along with future plans for improving and expanding these programs to bring astronomy education and research to a greater number of people and indeed to use Astronomy for a Better World. Information and advice will also be provided about applying for support in the future.

Practical Semantic Astronomy

NASA Astrophysics Data System (ADS)

Graham, Matthew; Gray, N.; Burke, D.

2010-01-01

Many activities in the era of data-intensive astronomy are predicated upon some transference of domain knowledge and expertise from human to machine. The semantic infrastructure required to support this is no longer a pipe dream of computer science but a set of practical engineering challenges, more concerned with deployment and performance details than AI abstractions. The application of such ideas promises to help in such areas as contextual data access, exploiting distributed annotation and heterogeneous sources, and intelligent data dissemination and discovery. In this talk, we will review the status and use of semantic technologies in astronomy, particularly to address current problems in astroinformatics, with such projects as SKUA and AstroCollation.

Astronomy and astrology

NASA Astrophysics Data System (ADS)

Zarka, Philippe

2011-06-01

Astrology meets a large success in our societies, from the private to the political sphere as well as in the media, in spite of the demonstrated inaccuracy of its psychological as well as operational predictions. We analyse here the relations between astrology and astronomy, as well as the criticisms opposed by the latter to the former. We show that most of these criticisms are weak. Much stronger ones emerge from the analysis of the astrological practice compared to the scientific method, leading us to conclude to the non-scientificity of astrology. Then we return to the success of astrology, and from its analysis we propose a renewed (and prophylactic) rôle for astronomy in society.

STS-Astro: Astronomy in focus of science, technology and society and analysis about the International Year of Astronomy 2009-Brazil

NASA Astrophysics Data System (ADS)

Ferreira, Orlando Rodrigues; Voelzke, Marcos Rincon

2012-10-01

This paper focuses on Science, Technology and Society around Astronomy an approach which authors call STS-Astro. It is considered that Astronomy is beyond the limits of Science itself, since it forwards to profound reflections on the own existence, predicated on the philosophical foundation of the Universe which is based on the anthropic principle. Subsequently, it discuss about the International Year of Astronomy 2009 in Brazil and their results. In 2003, Brazil, Italy and France sent a petition to the United Nations Educational, Scientific and Cultural Organization-UNESCO to consider 2009 as the International Year of Astronomy, on the occasion of 400 years of the first telescopic observations made in 1609 by Galileo Galilei (1568-1742). The International Year of Astronomy 2009 involved more than 148 countries and 815 million people, causing an unprecedented integration in the History between areas scientific, technological and humanities. Brazil had an outstanding performance, but even after a few years, numerous data in the country are still subject to studies and analyzes. The positive impacts on various sectors of the society have become permanent and aggregate actions in many institutions as schools, Universities, Observatories, Planetariums, Science Museums and the Astronomy Club, among others.

Bibliographic Resources for the Historian of Astronomy

NASA Astrophysics Data System (ADS)

Corbin, B. G.

1999-12-01

Many large library collections now have online bibliographic catalogs on the web. These provide many hidden resources for the historian of astronomy. Special searching techniques will allow the historian to scan bibliographic records of hundreds of entries relating to biographies of astronomers, collected works of astronomers, ancient and medieval astronomy and many other historical subjects. Abstract databases such as the Astrophysics Data System and ARIBIB are also adding much historical bibliographic information. ARIBIB will eventually contain scanned images of the Astronomischer Jahresbericht containing bibliographic entries for all literature of astronomy from 1899 to 1968 and Astronomy and Astrophysics Abstracts from 1969 to present. Commercial services such as UnCover and FirstSearch provide a means of reaching bibliographic entries for journal and book literature in the history of astronomy which were not easily located in the past. A broad overview of these collections and services will be given, and searching techniques for finding ``hidden" bibliographic data will be presented. Web page addresses will be given for all sources covered.

The aims, organizational plan and syllabus of a specialized Astronomy School with a subject of training students for participation in the International Astronomy Olympiad, are presented. Thematic frame includes basic educational activities during the preparation and self-preparation of the students and their participation in astronomical Olympiads. A model of identification and selection of outstanding students for astronomical Olympiads has been developed. Examples of didactic systems of problems for development of mathematical, physical and astronomical skills are shown. The programme ends with individual training for solving problems on astronomy and astrophysics. Possibilities, which the characteristic, non-standard astronomical problems give for stimulating the creative and original thinking, are specified. Basic psychological condition for development of the students' creative potential - transformation of the cognitive content in emotional one - is demonstrated. The programme of identification and support of outstanding students on astronomy is realized in collaboration with The Ministry of Education and Science, Public Astronomical Observatories and Planetaria, Institute of Astronomy - Bulgarian Academy of Sciences, and The Union of Astronomers in Bulgaria.

2018-06-01

Astronomy Research Seminars are offered by a rapidly growing number of community colleges and universities. Over the past decade some 120 student team research papers have been published with approximately 500 coauthors. Each team manages their own research, obtains and analyzes original data, writes a team paper, obtains an external review, submits their paper for publication, and gives a public PowerPoint presentation. The student teams are supported by: (1) an extensive community-of-practice which consists of professional and amateur astronomers, educators, and Seminar graduates; (2) the Institute for Student Astronomical Research (www.in4star.org); (3) the Small Telescope Astronomy Research Handbook and (4) an in-person/online, open-source Canvas learning management system with videos, quizzes, and other, extensive supporting material. Team research projects are completed in a semester or less and are managed by the students themselves. The Seminars have expanded from double star astronomy to asteroid astrometry, eclipsing binary times of minima, and exoplanet transits. Conducting authentic research inspires students, provides them with important skills in teamwork, project management and scientific literacy, and gives them confidence in their abilities to participate in scientific research. Being coauthors of published papers boosts student educational careers with respect to admissions and scholarships.

The Keck OSIRIS Nearby AGN (KONA) Survey: AGN Fueling and Feedback

NASA Astrophysics Data System (ADS)

Hicks, Erin K. S.; Müller-Sánchez, Francisco; Malkan, Matthew A.; Yu, Po-Chieh

In an effort to better constrain the relevant physical processes dictating the co-evolution of supermassive black holes and the galaxies in which they reside we turn to local Seyfert AGN. It is only with these local AGN that we can reach the spatial resolution needed to adequately characterize the inflow and outflow mechanisms thought to be the driving forces in establishing the relationship between black holes and their host galaxies at higher redshift. We present the first results from the KONA (Keck OSIRIS Nearby AGN) survey, which takes advantage of the integral field unit OSIRIS plus laser and natural guide star adaptive optics to probe down to scales of 5-30 parsecs in a sample of 40 local Seyfert galaxies. With these K-band data we measure the two-dimensional distribution and kinematics of the nuclear stars, molecular gas, and ionized gas within the central few hundred parsecs.

Young Astronomers and Astronomy teaching in Moldavia

Gaina, Alex

1998-09-01

Curricular Astronomy is taught in Moldavia , except Transnistria and Gagauzia, in the final (11th class) of the secondary schools and gymnasiums, and in the 12th class of the lyceums. The program takes 35 academic hours. The basic book is by Vorontsov-Veliaminov, used in the former USSR, but the Romanian one is also used, in spite of many criticisms addressed to both by our astronomy teachers. In Transinstria (on the left of the Dniester river)astronomy is taught 17 hours. Extracurricular activities develop at the Real Lyceum, where students and amateur astronomers carry out regular observations. Particularly, photographs of the comet Hale-Bopp have been realized using a Cassegrain 450 mm telescope by young astronomers under supervision of S. Luca and D. Gorodetzky (Gorodetchi). Except the telescope from the Real Lyceum other few telescopes are in construction. Unfortunately, no planetarium exists now in Chisinau, since the old one was returned to church. Astronomy courses are taught at the physical and mathematical departments of the Pedagogical University, Transnistrian Moldavian University in Tiraspol and the State University of |Moldavia. Many efforts were made by the State University lecturers and scientists to popularize Astronomy and Astrophysics in the books and in the press, at the radio and TV. No astronomy is taught at the Gagauzian National University in Comrat. No astronomiucal departments exist in Universities of |Moldavia.

Pondering astronomy's perplexingly preposterous propositions

NASA Astrophysics Data System (ADS)

Slater, Tim

2017-12-01

Astronomy is one of those ideas that naturally makes one wonder. Questions of how big? how far? how many? and how long? are just a few ideas that naturally present themselves when one contemplates the night sky and the universe. Despite astronomy's inherent ability to captivate students' interest, even master teachers need an evolving toolkit of innovative strategies to intellectually engage students, particularly in the domain of critical thinking.

Some innovative programmes in Astronomy education

NASA Astrophysics Data System (ADS)

Babu, G. S. D.; Sujatha, S.

In order to inculcate a systematic scientific awareness of the subject of Astronomy among the students and to motivate them to pursue careers in Astronomy and Astrophysics, various innovative educational programmes have been designed at MPBIFR. Among them, the main programme is termed as the ``100-hour Certificate Course in Astronomy and Astrophysics'' which has been designed basically for the students of the undergraduate level of B.Sc. and B.E. streams. The time duration of the 100 hours in this course is partitioned as 36 hours of classroom lectures, 34 hours of practicals and field trips and the remaining 30 hours being dedicated to dissertation writing and seminar presentations by the students. In addition, after the 100-hour course, the students have the option to take up specialized advance courses in the topics of Astrobiology, Astrochemistry, Radio Astronomy, Solar Astronomy and Cosmology as week-end classes. These courses are at the post graduate level and are covered in a span of 18 to 20 hours spread over a period of 9 to 10 weeks. As a preparatory programme, short-term introductory courses in the same subject are conducted for the high school students during the summer vacation period. Along with this, a three-week programme in basic Astronomy is also designed as an educational package for the general public. The students of these courses have the opportunity of being taken on field trips to various astronomical centers as well as the Radio, Solar and the Optical Observatories as part of their curriculum. The guided trips to the ISRO’s Satellite Centre at Bangalore and the Satellite Launching Station at SHAR provide high degree of motivation apart from giving thrilling experiences to the students. Further, the motivated students are encouraged to involve themselves in regular research programmes in Astronomy at MPBIFR for publishing research papers in national and international journals. The teaching and mentoring faculty for all these programmes

Problems facing promotion of astronomy in Arab countries

NASA Astrophysics Data System (ADS)

Osman, Anas M. I.

Promotion of astronomy in Arab countries is facing many scientific and technical problems. Teaching astronomy starts very late in schools, with very simple and limited courses. Many teachers lack a suitable astronomical background, which can lead to incorrect understanding by students of many astronomical ideas and phenomena. Teaching astronomy at higher levels is also very limited, for example: among the 16 universities in Egypt, astronomy is taught in only two faculties of science, just for two years. Graduate students find many difficulties in obtaining jobs related to astronomical activities and this is a serious limitation on the attraction of the study of astronomy. On the other hand, astronomical institutions are suffering from a serious lack of the new sophisticated equipment, while the budget allotted for maintenance is very small, and there is a serious shortage of technical staff. The training of astronomers and technicians is badly needed, since good research work depends on modern technological equipment and the complicated software used in controlling such equipment and in data analysis. Good libraries are needed for promotion of astronomy especially, the Internet facilities available for the staff is very limited. The effects of culture are very clear; many authorities in developing countries believe that astronomy is a luxury. Finally, most of astronomers are engaged with a lot of administration for all matters, so the free time left for science is very limited.

Dwarf planet Ceres: Ellipsoid dimensions and rotational pole from Keck and VLT adaptive optics images

NASA Astrophysics Data System (ADS)

Drummond, J. D.; Carry, B.; Merline, W. J.; Dumas, C.; Hammel, H.; Erard, S.; Conrad, A.; Tamblyn, P.; Chapman, C. R.

2014-07-01

The dwarf planet (1) Ceres, the largest object between Mars and Jupiter, is the target of the NASA Dawn mission, and we seek a comprehensive description of the spin-axis orientation and dimensions of Ceres in order to support the early science operations at the rendezvous in 2015. We have obtained high-angular resolution images using adaptive optics cameras at the W.M. Keck Observatory and the ESO VLT over ten dates between 2001 and 2010, confirming that the shape of Ceres is well described by an oblate spheroid. We derive equatorial and polar diameters of 967 ± 10 km and 892 ± 10 km, respectively, for a model that includes fading of brightness towards the terminator, presumably linked to limb darkening. These dimensions lie between values derived from a previous analysis of a subset of these images obtained at Keck by Carry et al. (Carry et al. [2008]. Astron. Astrophys. 478 (4), 235-244) and a study of Hubble Space Telescope observations (Thomas et al. [2005]. Nature 437, 224-226). Although the dimensions are 1-2% smaller than those found from the HST, the oblateness is similar. We find the spin-vector coordinates of Ceres to lie at (287°, +64°) in equatorial EQJ2000 reference frame (346°, +82° in ecliptic ECJ2000 coordinates), yielding a small obliquity of 3°. While this is in agreement with the aforementioned studies, we have improved the accuracy of the pole determination, which we set at a 3° radius.

KECK NIRSPEC RADIAL VELOCITY OBSERVATIONS OF LATE-M DWARFS

2012-11-15

We present the results of an infrared spectroscopic survey of 23 late-M dwarfs with the NIRSPEC echelle spectrometer on the Keck II telescope. Using telluric lines for wavelength calibration, we are able to achieve measurement precisions of down to 45 m s{sup -1} for our late-M dwarfs over a one- to four-year long baseline. Our sample contains two stars with radial velocity (RV) variations of >1000 m s{sup -1}. While we require more measurements to determine whether these RV variations are due to unseen planetary or stellar companions or are the result of starspots known to plague the surface ofmore » M dwarfs, we can place upper limits of <40 M{sub J} sin i on the masses of any companions around those two M dwarfs with RV variations of <160 m s{sup -1} at orbital periods of 10-100 days. We have also measured the rotational velocities for all the stars in our late-M dwarf sample and offer our multi-order, high-resolution spectra over 2.0-2.4 {mu}m to the atmospheric modeling community to better understand the atmospheres of late-M dwarfs.« less

Martín; Koresko; Kulkarni; Lane; Wizinowich

2000-01-20

We report observations obtained with the Keck adaptive optics facility of the nearby (d=9.8 pc) binary Gl 569. The system was known to be composed of a cool primary (dM2) and a very cool secondary (dM8.5) with a separation of 5&arcsec; (49 AU). We have found that Gl 569B is itself double with a separation of only 0&farcs;101+/-0&farcs;002 (1 AU). This detection demonstrates the superb spatial resolution that can be achieved with adaptive optics at Keck. The difference in brightness between Gl 569B and the companion is approximately 0.5 mag in the J, H, and K&arcmin; bands. Thus, both objects have similarly red colors and very likely constitute a very low mass binary system. For reasonable assumptions about the age (0.12-1.0 Gyr) and total mass of the system (0.09-0.15 M middle dot in circle), we estimate that the orbital period is approximately 3 yr. Follow-up observations will allow us to obtain an astrometric orbit solution and will yield direct dynamical masses that can constrain evolutionary models of very low mass stars and brown dwarfs.

The Ephemerides Association was founded last year by a PhD student in Astronomy. The association is devoted to the promotion and advancement of knowledge of the universe through research and education.The main activities of the association are scientific meetings, the planning and realization of scientific projects, the support of the scientific activities of its members, and the dissemination of related information among members and other interested persons.The association targets the disadvantaged zones of the Paris suburbs.The main issue was how to bring astronomy in those places. In the suburbs, since most of the youth are poor, most leisure activities like cinema are out of your reach. Thus, mostly of them will play football or basketball outside.We decided to go to meet young people who find themselves together in the evening. We prepare the telescope as well as the fasicules to start the observation of the planets. The discussion finally lead to their career plans and aspirations. Astronomy has become a tool to address societal issues. We present our results after one year of activity.

Direct Detection and Orbit Analysis of the Exoplanets HR 8799 bcd from Archival 2005 Keck/NIRC2 Data

Currie, Thayne; Fukagawa, Misato; Thalmann, Christian; Matsumura, Soko; Plavchan, Peter

2012-01-01

We present previously unpublished July 2005 H-band coronagraphic data of the young, planet-hosting star HR 8799 from the newly-released Keck/NIRC2 archive. Despite poor observing conditions, we detect three of the planets (HR 8799 bcd), two of them (HR 8799 bc) without advanced image processing. Comparing these data with previously published 1998-2011 astrometry and that from re-reduced October 2010 Keck data constrains the orbits of the planets. Analyzing the planets' astrometry separately, HR 8799 d's orbit is likely inclined at least 25 deg from face-on and the others may be on in inclined orbits. For semimajor axis ratios consistent with a 4:2:1 mean-motion resonance our analysis yields precise values for HR 8799 bcd's orbital parameters and strictly constrains the planets' eccentricities to be less than 0.18-0.3. However, we find no acceptable orbital solutions with this resonance that place the planets in face-on orbits; HR 8799 d shows the largest deviation from such orbits. Moreover, few orbits make HR 8799 d coplanar with b and c, whereas dynamical stability analyses used to constrain the planets' masses typically assume coplanar and/or fare.on orbits. This paper illustrates the significant science gain enabled with the release of the NIRC2 archive.

Astronomy in Primary and Secondary Education in Slovenia

NASA Astrophysics Data System (ADS)

Gomboc, Andreja

2015-08-01

I will present the status of astronomy in educational system in Slovenia. In primary schools astronomy is offered as an optional course in the last 3 grades (12-15 yrs old), while in secondary schools a few astronomical topics are present only as part of other subjects (e.g. physics, geography). I will describe a pilot project of an astronomy course in secondary schools, which was carried out in the school year 2013/14. The main focus of my presentation will be the experience gained with organisation of the Slovenian National Astronomy Competition. It is organised by the Slovenian Society of Mathematicians, Physicists and Astronomers since 2009, building on an extensive network of over 200 primary and secondary school teachers who participated in IYA2009 activities, and who now represent majority of mentors for the competition. In 2013, only 5 years after the start of competition, our pupils attended the International Olympiad on Astronomy and Astrophysics for the first time and with great success. Supporting activities include the Slovenian version of the Portal to the Universe (www.portalvvesolje.si) and translation of Space Scoop astronomy news for children.

Astronomy on Tap public outreach events are as easy to organise or as elaborate as you would like them to be. In addition to communicating cutting-edge research and fundamental concepts to the public, Astronomy on Tap events showcase the passion, creativity and diversity of scientists, facilitate personal and meaningful interactions between scientists and the general public, and offer networking and professional development opportunities for scientists. Astronomy on Tap organisers provide a growing cadre of resources for starting similar events, which have so far taken place in twenty locations around the world, mainly in the United States but also in Canada, Chile, and Taiwan, reaching a total of almost 15 000 people. Through this reflection on the Astronomy on Tap project we invite you to consider whether you could adopt aspects of the Astronomy on Tap model for existing outreach programmes, or even organise a new satellite event in your location.

Astronomy on Tap is a series of free lectures by astronomers in the pub, aimed at disseminating the latest research to the public in an informal setting. Started in New York City in 2013, Astronomy on Tap has now expanded to seven cities across North and South America. Organized by local astronomers, each event features talks by astronomers from local institutions or visitors, or others whose professions or hobbies intersect with astronomy, along with games and opportunities for the public to interact with professional astronomers. The largest Astronomy on Tap events are in Austin, Texas, attracting over 150 people each month, which consists of populations outside of the self-selected groups that might be reached by more formal EPO activities. The organisers of Astronomy on Tap in Austin (AoTATX) will discuss the impact of and feedback from all of the locations, and present information on setting up new satellite locations.

Infrared Astronomy Satellite

In 1982, the Infrared Astronomy Satellite (IRAS) will be launched into a 900-km sun-synchronous (twilight) orbit to perform an unbiased, all-sky survey of the far-infrared spectrum from 8 to 120 microns. Observations telemetered to ground stations will be compiled into an IR astronomy catalog. Attention is given the cryogenically cooled, 60-cm Ritchey-Chretien telescope carried by the satellite, whose primary and secondary mirrors are fabricated from beryllium by means of 'Cryo-Null Figuring'. This technique anticipates the mirror distortions that will result from cryogenic cooling of the telescope and introduces dimensional compensations for them during machining and polishing. Consideration is also given to the interferometric characterization of telescope performance and Cryo/Thermal/Vacuum simulated space environment testing.

Shankar, Rama; Deb, Sourabh; Sharma, B K

2012-01-01

The need for an alternative drug for malaria initiated intensive efforts for developing new antimalarials from indigenous plants. The information from different tribal communities of northeast India along with research papers, including books, journals and documents of different universities and institutes of northeast India was collected for information on botanical therapies and plant species used for malaria. Sixty-eight plant species belonging to 33 families are used by the people of northeast India for the treatment of malaria. Six plant species, namely, Alstonia scholaris, Coptis teeta, Crotolaria occulta, Ocimum sanctum, Polygala persicariaefolia, Vitex peduncularis, have been reported by more than one worker from different parts of northeast India. The species reported to be used for the treatment of malaria were either found around the vicinity of their habitation or in the forest area of northeast India. The most frequently used plant parts were leaves (33%), roots (31%), and bark and whole plant (12%). The present study has compiled and enlisted the antimalarial plants of northeast India, which would help future workers to find out the suitable antimalarial plants by thorough study.

iSTAR: The International STudy on Astronomy Reasoning

NASA Astrophysics Data System (ADS)

Tatge, Coty B.; Slater, Timothy F.; Slater, Stephanie J.

2015-08-01

This paper reports the first steps taken in the International STudy on Astronomy Reasoning (iSTAR). The iSTAR Project is an attempt to look beyond traditional wisdom and practices in astronomy education, to discover the ways in which cognitive abilities and human culture interact to impact individuals’ understanding of and relationship to astronomy content knowledge. In contrast to many international studies that seek to rank nations by student performance on standardized tests, the iSTAR Project seeks to find ways that culture may unexpectedly enhance performance in astronomy. Using the Test of Astronomy Standards (TOAST) as a reasonable, initial proxy for the content knowledge a well educated person might know in astronomy, the iSTAR team then defined culture as a construct with five components: practices, traditional knowledge, historical and genealogical relationships, place-based knowledge, and language. Given the complexity of this construct, Stage 1 of the project focuses on the cultural component of language, and assumed that prior to the collection of data from students, the process of translating the TOAST could provide valuable expert-based information on the impact of language on astronomy knowledge. As such, the work began with a study of the translation process. For each of the languages used in the testing phase of the iSTAR protocol, a succession of translators and analysts were engaged, including two educated, non-astronomer native speakers, a native speaking astronomer, and a native speaking linguistics expert. Multiple translations were analyzed in order to make relevant meaning of differences in the translations, and provide commentary on the ways in which metaphor, idiom, cultural history are embedded in the language, providing potential advantages in the learning of astronomy. The first test languages were German, Hawaiian, and American Sign Language, and initial findings suggest that each of these languages provide specific advantages

A Pilot Astronomy Outreach Project in Bangladesh

Bhattacharya, Dipen; Mridha, Shahjahan; Afroz, Maqsuda

2015-08-01

In its strategic planning for the "Astronomy for Development Project," the International Astronomical Union (IAU) has ecognized, among other important missions, the role of astronomy in understanding the far-reaching possibilities for promoting global tolerance and citizenship. Furthermore, astronomy is deemed inspirational for careers in science and technology. The "Pilot Astronomy Outreach Project in Bangladesh"--the first of its kind in the country--aspires to fulfill these missions. As Bangladesh lacks resources to promote astronomy education in universities and schools, the role of disseminating astronomy education to the greater community falls on citizen science organizations. One such group, Anushandhitshu Chokro (AChokro) Science Organization, has been carrying out a successful public outreach program since 1975. Among its documented public events, AChokro organized a total solar eclipse campaign in Bangladesh in 2009, at which 15,000 people were assembled in a single open venue for the eclipse observation. The organization has actively pursued astronomy outreach to dispel public misconceptions about astronomical phenomena and to promote science. AChokro is currently working to build an observatory and Science Outreach Center around a recently-acquired 14-inch Scmidt-Cassegrain telescope and a soon-to-be-acquired new 16-inch reflector, all funded by private donations. The telescopes will be fitted with photometers, spectrometers, and digital and CCD cameras to pursue observations that would include sun spot and solar magnetic fields, planetary surfaces, asteroid search, variable stars and supernovae. The Center will be integrated with schools, colleges, and community groups for regular observation and small-scale research. Special educational and observing sessions for adults will also be organized. Updates on the development of the Center, which is expected to be functioning by the end of 2015, will be shared and feedback invited on the fostering of

The Development of Astronomy and Emergence of Astrophysics in Japan

NASA Astrophysics Data System (ADS)

Nakamura, Tsuko

This chapter overviews the emergence and development phases of modern astronomy and astrophysics in Japan, mainly before WWII. In the beginning of the nineteenth century under the samurai regime of the Tokugawa Shogunate, shogunal astronomers started to learn Western astronomy through a Dutch translation of the book Astronomie by J.J. Lalande. After the Meiji Restoration (1868) the new government founded the University of Tokyo (1877), the first modern university in Japan, in which Tokyo Astronomical Observatory (TAO) also started in 1888. Terao Hisashi, who had gone to Paris to study the modern astronomy, became the first Director of TAO in 1888. The astronomy introduced by Terao into Japan was so-called classical astronomy. Two of Terao's early students made Japan's first internationally recognized achievements in astronomy, the discovery of the Z-term in the polar motion of the Earth by Kimura (Astronomische Nachrichten, 158, 234-240, 1902) and the discovery of asteroid families by Hirayama (Astronomical Journal, 31, 185-188, 1918).

While there have been many outreach activities and telescope observations at city sidewalks and parks, this program targets a completely different audience - music lovers who attend summer concerts held in community parks. These music lovers who may never have visited a science museum, planetarium, or star party are exposed to telescope observations and astronomy information with no additional travel costs. Music and Astronomy Under the Stars increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. This program includes solar observing before the concerts, telescope observations including a live image projection system, an astronomical video presentation, and astronomy banners/posters. Approximately 500 - 16,000 people attended each event and 25% to 50% of the people at each event participated in the astronomy program. This program also reached underrepresented and underserved groups (women, minorities, older adults). The target audience is 2,900,000 people, which is larger than combined population of Atlanta, Boston, Denver, Minneapolis, and San Francisco. Although eleven events were planned in 2009, two were canceled due to rain and our largest event, the NY Philharmonic in the Park (attended by 67,000 people in 2008), was cancelled for financial reasons. Our largest event in 2009 was the Tanglewood Music Festival, Lenox MA, attended by 16,000 people where 5000 people participated in astronomy activities. The Amateur Observers' Society of NY assisted with the NY concerts and the Springfield STARS club assisted at Tanglewood. 1500 people looked through telescopes at the Halloween program (6000 saw the posters). In 2009 over 15,000 people participated in these astronomy activities which were attended by

Astronomy: On the Bleeding Edge of Scholarly Infrastructure

The infrastructure for scholarship has moved online, making data, articles, papers, journals, catalogs, and other scholarly resources nodes in a deeply interconnected network. Astronomy has led the way on several fronts, developing tools such as ADS to provide unified access to astronomical publications and reaching agreement on a common data file formats such as FITS. Astronomy also was among the first fields to establish open access to substantial amounts of observational data. We report on the first three years of a long-term research project to study knowledge infrastructures in astronomy, funded by the NSF and the Alfred P. Sloan Foundation. Early findings indicate that the availability and use of networked technologies for integrating scholarly resources varies widely within astronomy. Substantial differences arise in the management of data between ground-based and space-based missions and between subfields of astronomy, for example. While large databases such as SDSS and MAST are essential resources for many researchers, much pointed, ground-based observational data exist only on local servers, with minimal curation. Some astronomy data are easily discoverable and usable, but many are not. International coordination activities such as IVOA and distributed access to high-level data products servers such as SIMBAD and NED are enabling further integration of published data. Astronomers are tackling yet more challenges in new forms of publishing data, algorithms, visualizations, and in assuring interoperability with parallel infrastructure efforts in related fields. New issues include data citation, attribution, and provenance. Substantial concerns remain for the long term discoverability, accessibility, usability, and curation of astronomy data and other scholarly resources. The presentation will outline these challenges, how they are being addressed by astronomy and related fields, and identify concerns and accomplishments expressed by the astronomers we have

History of Astronomy in Portugal: Theories, Institutions and Practices

NASA Astrophysics Data System (ADS)

Saraiva, Luis

2014-01-01

In Portugal, throughout its history, astronomy was developed in the context of the mathematical sciences. During the times of Portugal's Maritime Discoveries, astronomical navigation was based on spherical trigonometry, and therefore it was the mathematicians who taught astronomy to the pilots. During the 17th century, basic notions of astronomy were taught in mathematical courses in the University and in the main Jesuit colleges. This tradition continued in the 18th century, so it is no wonder that one of the most influent Portuguese astronomers during this period was the mathematician José Monteiro da Rocha. During the 19th century the new centres of science teaching, as the Polytechnic School in Lisbon, or the Polytechnic Academy in Oporto, developed astronomy teaching and research in the context of the mathematics subjects. The inheritors of these 19th century institutions, respectively the Faculties of Sciences of Lisbon and Oporto, upheld this tradition until the final decades of 20th century and continued to consider astronomy as a subject to be taught in their mathematics departments. This Meeting aims at outlining several perspectives on the history of astronomy in Portugal, particularly analysing its ties with mathematical sciences and astronomy applications. The Meeting is organised by the Museum of Science of the University of Lisbon (MCUL) with CMAF, CMUC, CMUP and the CIUHCT, and is included in CIM events. It is integrated in the commemorations of the International Year of Astronomy (IYA2009).

To See the Unseen: A History of Planetary Radar Astronomy

NASA Technical Reports Server (NTRS)

Butrica, Andrew J.

1996-01-01

This book relates the history of planetary radar astronomy from its origins in radar to the present day and secondarily to bring to light that history as a case of 'Big Equipment but not Big Science'. Chapter One sketches the emergence of radar astronomy as an ongoing scientific activity at Jodrell Bank, where radar research revealed that meteors were part of the solar system. The chief Big Science driving early radar astronomy experiments was ionospheric research. Chapter Two links the Cold War and the Space Race to the first radar experiments attempted on planetary targets, while recounting the initial achievements of planetary radar, namely, the refinement of the astronomical unit and the rotational rate and direction of Venus. Chapter Three discusses early attempts to organize radar astronomy and the efforts at MIT's Lincoln Laboratory, in conjunction with Harvard radio astronomers, to acquire antenna time unfettered by military priorities. Here, the chief Big Science influencing the development of planetary radar astronomy was radio astronomy. Chapter Four spotlights the evolution of planetary radar astronomy at the Jet Propulsion Laboratory, a NASA facility, at Cornell University's Arecibo Observatory, and at Jodrell Bank. A congeries of funding from the military, the National Science Foundation, and finally NASA marked that evolution, which culminated in planetary radar astronomy finding a single Big Science patron, NASA. Chapter Five analyzes planetary radar astronomy as a science using the theoretical framework provided by philosopher of science Thomas Kuhn. Chapter Six explores the shift in planetary radar astronomy beginning in the 1970s that resulted from its financial and institutional relationship with NASA Big Science. Chapter Seven addresses the Magellan mission and its relation to the evolution of planetary radar astronomy from a ground-based to a space-based activity. Chapters Eight and Nine discuss the research carried out at ground

It is vital for the instructors and designers of the Massive Open Online Courses (MOOCs) to understand the motivation of its users for enrolling in the class and their reasons to engage with the material. This is particularly important for MOOCs focusing on scientific topics such as our MOOC on Astronomy (Astronomy: Exploring time and space) whose audience is less motivated by a desire to advance their careers compared to other MOOCs. In order to learn more about the motivation of our learners we deployed in our Astronomy MOOC a survey based on the Science Motivation Questionnaire II developed by Glynn et. al (2011). We specifically asked for reasons to sign up for the course and the overall motivation and attitude towards astronomy and science courses. We compare results of 3360 participants of this survey with a similar instrument administered to 638 students in undergraduate Astronomy classes for non Astronomy majors at the University of Arizona. Our comparison not only looks at the demographic differences, but also at reasons for signing up for the course and scores in motivational categories such as self-determination, self-efficacy, grade motivation, career motivation, hobby motivation, social motivation, and intrinsic motivation showing, that these populations of learners are fundamentally different.

Summary: Special Session SpS15: Data Intensive Astronomy

NASA Astrophysics Data System (ADS)

Montmerle, Thierry

2015-03-01

A new paradigm in astronomical research has been emerging - ``Data Intensive Astronomy'' that utilizes large amounts of data combined with statistical data analyses. The first research method in astronomy was observations by our eyes. It is well known that the invention of telescope impacted the human view on our Universe (although it was almost limited to the solar system), and lead to Keplerfs law that was later used by Newton to derive his mechanics. Newtonian mechanics then enabled astronomers to provide the theoretical explanation to the motion of the planets. Thus astronomers obtained the second paradigm, theoretical astronomy. Astronomers succeeded to apply various laws of physics to reconcile phenomena in the Universe; e.g., nuclear fusion was found to be the energy source of a star. Theoretical astronomy has been paired with observational astronomy to better understand the background physics in observed phenomena in the Universe. Although theoretical astronomy succeeded to provide good physical explanations qualitatively, it was not easy to have quantitative agreements with observations in the Universe. Since the invention of high-performance computers, however, astronomers succeeded to have the third research method, simulations, to get better agreements with observations. Simulation astronomy developed so rapidly along with the development of computer hardware (CPUs, GPUs, memories, storage systems, networks, and others) and simulation codes.

John Quincy Adams's rhetorical crusade for astronomy.

PubMed

Portolano, M

2000-09-01

Astronomy thrived in Europe during the early nineteenth century, but in the United States a utilitarian mind-set opposed it. John Quincy Adams's oratory in support of American astronomical discovery reached its peak during congressional debate over the Smithsonian Institution (1838-1846). During this debate Adams countered proposals to found a university with plans for an observatory. His addresses to congressional and public audiences about observatories and astronomy were intended to foster interest in the science and encourage the growing astronomical community in America. Although the U.S. Naval Observatory in Washington, D.C., was established before the Smithsonian debate ended, many considered Adams its political father. Adams composed his speeches on astronomy in a systematic manner, following neoclassical principles of rhetoric that he had taught at Harvard University. His speeches both in and outside of Congress show evidence of the rhetorical principles he conscientiously used in the service of astronomy.

Women's and men's career choices in astronomy and astrophysics

NASA Astrophysics Data System (ADS)

Ivie, Rachel; White, Susan; Chu, Raymond Y.

2016-12-01

[This paper is part of the Focused Collection on Gender in Physics.] The Longitudinal Study of Astronomy Graduate Students (LSAGS) arose from the 2003 Women in Astronomy Conference, where it was noted that a majority of young members of the American Astronomical Society were women. The astronomy community wishes to make every effort to retain young women in astronomy, so they commissioned a longitudinal study to be conducted that would pinpoint the factors that contribute to retention in general, with a focus on differences between women and men. The LSAGS follows a cohort of people who were graduate students in astronomy or astrophysics during 2006-07. The first survey was conducted during 2007-08 and the second during 2012-13. The analysis presented in this paper used a subset of the respondents, all of whom had Ph.D.s in astronomy, astrophysics, or a related field at the time of the second survey. We tested the effects of four major concepts on two measures of attrition from physics and astronomy. These concepts included the imposter syndrome, mentoring and advising during graduate school, the "two-body problem" that occurs when a couple needs to find two jobs in the same geographic area, and the sex of the respondent. While the imposter syndrome and mentoring affected the likelihood of respondents' thinking about leaving the field, they did not directly contribute to actually working in a field that was not physics or astronomy. Relationship with graduate advisors and the two-body problem both had significant effects on working in physics or astronomy, as did completing a postdoc. The sex of the respondent had no direct effect on our measures of attrition, but indirectly affected attrition because women were less likely to report positive relationships with graduate advisors and more likely to report two-body problems. This research identifies specific areas of concern that can be addressed by the scientific community to increase the retention of all people

Improving Teach Astronomy: A Survey of Instructors

NASA Astrophysics Data System (ADS)

Wenger, Matthew; Riabokin, Malanka; Impey, Chris David

2018-01-01

Teach Astronomy is a website that provides educational resources for introductory astronomy. The motivation behind constructing this site was to provide quality online educational tools for use as a primary or supplementary instructional resource for teachers and students. The website provides an online textbook, glossary, podcasts and video summaries of concepts. As the popularity of online courses steadily increases, so does the demand for robust online educational resources. In order to cater to our users, our team conducted a survey of the instructors that use Teach Astronomy site for feedback for use in updating and streamlining the website content. The survey collected feedback regarding functionality of each of the website tools, in which courses the site was being used, and the motivation of the instructors use of our site. The overwhelming majority of responses indicate that instructors use the website as a class textbook in introductory astronomy courses for non-science majors, and instructors also generally tended to agree that the site content was comprehensive and lucid. One interesting result of the survey is to cluster topics in a way that is consistent with different levels of instruction (i.e. grouping middle-school level content and university level content distinctly). Our team will use this feedback to improve the Teach Astronomy website and maintain it as a high-quality, free online resource. We will also continue to gather feedback from instructors to ensure that the Teach Astronomy website stays current and remains a valuable online resource for instructors around the country.

Keck Spectroscopy of Redshift z ~ 3 Galaxies in the Hubble Deep Field

NASA Astrophysics Data System (ADS)

Lowenthal, James D.; Koo, David C.; Guzmán, Rafael; Gallego, Jesús; Phillips, Andrew C.; Faber, S. M.; Vogt, Nicole P.; Illingworth, Garth D.; Gronwall, Caryl

1997-05-01

We have obtained spectra with the 10 m Keck telescope of a sample of 24 galaxies having colors consistent with star-forming galaxies at redshifts 2 <~ z <~ 4.5 in the Hubble deep field (HDF). Eleven of these galaxies are confirmed to be at high redshift (zmed = 3.0), one is at z = 0.5, and the other 12 have uncertain redshifts but have spectra consistent with their being at z > 2. The spectra of the confirmed high-redshift galaxies show a diversity of features, including weak Lyα emission, strong Lyα breaks or damped Lyα absorption profiles, and the stellar and interstellar rest-UV absorption lines common to local starburst galaxies and high-redshift star-forming galaxies reported recently by others. The narrow profiles and low equivalent widths of C IV, Si IV, and N V absorption lines may imply low stellar metallicities. Combined with the five high-redshift galaxies in the HDF previously confirmed with Keck spectra by Steidel et al. (1996a), the 16 confirmed sources yield a comoving volume density of n >= 2.4 × 10-4 h350 Mpc-3 for q0 = 0.05, or n >= 1.1 × 10-3 h350 Mpc-3 for q0 = 0.5. These densities are 3-4 times higher than the recent estimates of Steidel et al. (1996b) based on ground-based photometry with slightly brighter limits and are comparable to estimates of the local volume density of galaxies brighter than L*. The high-redshift density measurement is only a lower limit and could be almost 3 times higher still if all 29 of the unconfirmed candidates in our original sample, including those not observed, are indeed also at high redshift. The galaxies are small but luminous, with half-light radii 1.8 < r1/2 < 6.5 h-150 kpc and absolute magnitudes -21.5 > MB > -23. The HST images show a wide range of morphologies, including several with very close, small knots of emission embedded in wispy extended structures. Using rest-frame UV continuum fluxes with no dust correction, we calculate star formation rates in the range 7-24 or 3-9 h-250 Msolar yr-1 for q

Engaging "K-to-Gray” audiences (children, families, and older adults) in astronomical activities is one of the main goals of the NJMC Center for Environmental and Scientific Education and the William D. McDowell Observatory located in Lyndhurst, NJ. Perched atop a closed and reclaimed municipal solid waste landfill, our new LEED - certified building (certification pending) and William D. McDowell observatory will assist in bringing the goals of IYA 2009 to the approximately 25,000 students and 15,000 adults that visit our site from the NY/NJ region each year. Diversifying our traditional environmental science offerings, we have incorporated astronomy into our repertoire with "The Sun Through Time” module, which includes storytelling, cultural astronomy, telescope anatomy, and other activities that are based on the electromagnetic spectrum and our current knowledge of the sun. These lessons have also been modified to bring astronomy to underserved communities, specifically those individuals that have dexterity or cognitive ability differences. The program is conducted in a classroom setting and is designed to meet New Jersey Core Curriculum Content Standards. With the installation of our new 20” telescope, students and amateur astronomers will be given the opportunity to perform rudimentary research. In addition, a program is in development that will allow individuals to measure local sky brightness and understand the effects of light pollution on astronomical viewing. Teaching astronomy in an urban setting presents many challenges. All individuals, regardless of ability level or location, should be given the opportunity to be exposed to the wonders of the universe and the MEC/CESE has been successful in providing those opportunities.

Grote Reber, Radio Astronomy Pioneer, Dies

NASA Astrophysics Data System (ADS)

2002-12-01

Grote Reber, one of the earliest pioneers of radio astronomy, died in Tasmania on December 20, just two days shy of his 91st birthday. Reber was the first person to build a radio telescope dedicated to astronomy, opening up a whole new "window" on the Universe that eventually produced such landmark discoveries as quasars, pulsars and the remnant "afterglow" of the Big Bang. His self- financed experiments laid the foundation for today's advanced radio-astronomy facilities. Grote Reber Grote Reber NRAO/AUI photo "Radio astronomy has changed profoundly our understanding of the Universe and has earned the Nobel Prize for several major contributions. All radio astronomers who have followed him owe Grote Reber a deep debt for his pioneering work," said Dr. Fred Lo, director of the National Radio Astronomy Observatory (NRAO). "Reber was the first to systematically study the sky by observing something other than visible light. This gave astronomy a whole new view of the Universe. The continuing importance of new ways of looking at the Universe is emphasized by this year's Nobel Prizes in physics, which recognized scientists who pioneered X-ray and neutrino observations," Lo added. Reber was a radio engineer and avid amateur "ham" radio operator in Wheaton, Illinois, in the 1930s when he read about Karl Jansky's 1932 discovery of natural radio emissions coming from outer space. As an amateur operator, Reber had won awards and communicated with other amateurs around the world, and later wrote that he had concluded "there were no more worlds to conquer" in radio. Learning of Jansky's discovery gave Reber a whole new challenge that he attacked with vigor. Analyzing the problem as an engineer, Reber concluded that what he needed was a parabolic-dish antenna, something quite uncommon in the 1930s. In 1937, using his own funds, he constructed a 31.4-foot-diameter dish antenna in his back yard. The strange contraption attracted curious attention from his neighbors and became

We present measurements of polarization lensing using the 150 GHz maps, which include all data taken by the BICEP2 and Keck Array Cosmic Microwave Background polarization experiments up to and including the 2014 observing season (BK14). Despite their modest angular resolution (˜ 0.5°), the excellent sensitivity (˜3μK-arcmin) of these maps makes it possible to directly reconstruct the lensing potential using only information at larger angular scales ({ℓ}≤700). From the auto-spectrum of the reconstructed potential, we measure an amplitude of the spectrum to be ALφ φ=1.15+/- 0.36 (Planck ΛCDM prediction corresponds to ALφ φ =1) and reject the no-lensing hypothesis at 5.8σ , which is the highest significance achieved to date using an EB lensing estimator. Taking the cross-spectrum of the reconstructed potential with the Planck 2015 lensing map yields ALφ φ =1.13+/- 0.20. These direct measurements of ALφ φ are consistent with the ΛCDM cosmology and with that derived from the previously reported BK14 B-mode auto-spectrum (AL{BB}=1.20+/- 0.17). We perform a series of null tests and consistency checks to show that these results are robust against systematics and are insensitive to analysis choices. These results unambiguously demonstrate that the B modes previously reported by BICEP/Keck at intermediate angular scales (150≲ ℓ ≲ 350) are dominated by gravitational lensing. The good agreement between the lensing amplitudes obtained from the lensing reconstruction and B-mode spectrum starts to place constraints on any alternative cosmological sources of B modes at these angular scales.

Postwar Radio Astronomy and the US Military

NASA Astrophysics Data System (ADS)

Sullivan, W. T., III

1993-12-01

The course of radio astronomy in the United States during the period 1945-60 was greatly influenced by the funding and requirements of the US military. The scientific researchers and their military patrons continued the intimate relationship that had been so successful for the development of radar and communications during World War II. The result was a very high level of funding that led to large-scale projects, a concentration on the microwave portion of the radio spectrum, and primary interest in the sun, moon, and planets. These effects, however, ironically significantly contributed to the lag in US radio astronomy relative to that in Australia and England. Unlike the American approach, the strategy of the groups in Sydney, Cambridge and Jodrell Bank, reasoned that the most fruitful way to approach the radio sky at the time was with relatively simple equipment (largely revamped war surplus) operating at the lower frequencies. Other factors, such as the strength of optical astronomy in the US, also played important roles. By the mid-1960s, the microwave expertise that had been developed in the US finally paid off such that US radio astronomy was at last able to assume a position of more parity. Some similarities in the development of postwar Soviet radio astronomy will also be discussed.

Astronomy from Olbers to Schwarzschild. (German Title: Astronomie von Olbers bis Schwarzschild)

NASA Astrophysics Data System (ADS)

Dick, Wolfgang R.; Hamel, Jürgen

This issue comprises talks presented 2000 September 18 at the colloquium ``International relations in astronomy'' it is supplemented by additional articles about this topic. The foundation of the international ``Vereinigte Astronomische Gesellschaft'', which took place in 1800 in Bremen, prompted us to investigate the development of astronomy in German-speaking regions, and its international relations during the 19th century. We investigate the activities of famous astronomers like W. Olbers, J.E. Bode, F.X. von Zach, J.H. Schroeter, H.C. Schumacher and K. Schwarzschild, as well as those of their less famous professional colleagues like J.G. Schrader and L. de Ball. The geographical spectrum extends from Bremen and Lilienthal over Kiel, Gotha and Dresden to Copenhagen, Vienna and Chile. Among the topics are: telescope construction, including telescopes made by Herschel, the rediscovery of the minor planet Ceres 1801/02, the Berlin ``Astronomisches Jahrbuch'', the foundation of the ``Astronomische Nachrichten'', the evolution from the ``Vereinigte Astronomische Gesellschaft'' to the present-day ``Astronomische Gesellschaft'', the research at the Kuffner Observatory in Vienna, the professionalization in astronomy, and the attempts of many countries to establish a southern observatory in Chile. A listing of astronomical monuments in Lilienthal and Bremen concludes the book. All papers are written in German with English abstracts.

The 2012 Transit of Venus provided a new opportunity to study the events that occur during the ingress and egress of transit in greater detail. The Venus Twilight Experiment is a group that was formed to analyze the twilight phenomena of Venus through close and careful observation of planet’s 21st century transits. One particular object of interest to this group is the Cytherean aureole, or the arc of light caused by refraction of the Sun’s light through Venus’s upper atmosphere. A goal associated with the study of this aureole is to measure how the brightness of the atmosphere changes over time and as a function of latitude on Venus with the use of the multitude of images taken of the planet near the beginning and end of the transit. In order to further along this goal, I was tasked with sorting, processing, and aligning the images taken by the coronagraph used on the 2012 Williams College Transit of Venus Expedition at Haleakala, Hawaii. Our observations through a B filter will be compared with observations through VRI-filter observations from other coronagraphs in the set. This was research was performed with the support of the Keck Northeast Astronomy Consortium, sponsored by the NSF and the Keck foundation. The expedition to Haleakala and Sac Peak was sponsored by the Committee for Research and Exploration/National Geographic Society. Some funds for the IBIS carbon-dioxide filter came from NASA/AAS's Small Research Grant Program. We thank Rob Ratkowski, Stan Truitt, Rob Lucas, Aram Friedman, and Eric Pilger '82 for assistance with Haleakala observing.

The Development of Astronomy and Emergence of Astrophysics in Thailand

NASA Astrophysics Data System (ADS)

Soonthornthum, Boonrucksar

Astronomy was introduced to Siam (present-day Thailand) over 300 years ago during the reign of King Narai, the Great. The first astronomical observatory was built in Loburi province by French missionary-astronomers and various astronomical instruments were brought to Siam at that time. After King Narai died, astronomy was neglected for over 180 years until the reign of King Rama IV when astronomy became more popular. Members of the Royal Family, King Rama IV in particular, were very interested in astronomy and hence became patrons of modern astronomy in Siam. King Rama IV himself made a precise calculation of the time and location of a total solar eclipse which could be observed from Siam on 18 August 1868. However, modern astronomy in Siam did not evolve rapidly at this time, due in part to the slow development of the educational system.

The Making of the Fathers of Astronomy Exhibit

Graney, C. M.

2010-10-01

The International Year of Astronomy 2009 stretched a few days into 2010 here in Louisville, Kentucky - the Fathers of Astronomy exhibit at the Frazier International History Museum did not close until 3 January 2010. Fathers of Astronomy, which was open for five months, told the story of Galileo through authentic original editions of three books - the 1493 Nuremberg Chronicle, Nicolas Copernicus's 1543 On the Revolutions of Heavenly Spheres, and Galileo Galilei's 1632 Dialogue Concerning the two Chief World Systems. The success of "Fathers" resulted from three very different partners coming together and combining resources to produce a history-themed IYA2009 programme of the highest quality at minimal cost. Lessons learned from the exhibit may be of value to people interested in communicating astronomy to the public.

ZTF Undergraduate Astronomy Institute at Caltech and Pomona College

Penprase, Bryan Edward; Bellm, Eric Christopher

2017-01-01

From the new Zwicky Transient Facility (ZTF), an NSF funded project based at Caltech, comes a new initiative for undergraduate research known as the Summer Undergraduate Astronomy Institute. The Institute brings together 15-20 students from across the world for an immersive experience in astronomy techniques before they begin their summer research projects. The students are primarly based at Caltech in their SURF program but also includes a large cohort of students enrolled in research internships at Pomona College in nearby Claremont CA. The program is intended to introduce students to research techniques in astronomy, laboratory and computational technologies, and to observational astronomy. Since many of the students are previously computer science or physics majors with little astronomy experience, this immersive experience has been extremely helpful for enabling students to learn about the terminologies, techniques and technologies of astronomy. The field trips to the Mount Wilson and Palomar telescopes deepen their knowledge and excitement about astronomy. Lectures about astronomical research from Caltech staff scientists and graduate students also provide context for the student research. Perhaps more importantly, the creation of a cohort of like-minded students, and the chance to reflect about careers in astronomy and research, give these students opportunities to consider themselves as future research scientists and help them immensely as they move forward in their careers. We discuss some of the social and intercultural aspects of the experience as well, as our cohorts typically include international students from many countries and several students from under-represented groups in science.

Over the past three years, McDonald Observatory has offered special Astronomy Day videoconference programs to students across Texas—the second largest state in the U.S. (Only Alaska is larger). Videoconferencing allows many students and teachers access to our Observatory, which is remotely located 180 miles (290 kilometers) from any major city. McDonald Observatory partners with Connect2Texas to advertise the Astronomy Day event. Connect2Texas provides the electronic bridge between schools and the Observatory. They also provide an online evaluation for teachers to complete. In 2009 the Astronomy Day videoconference celebrated the International Year of Astronomy and the historic observations made by Galileo Galilei. During the videoconference, the classes explore the Moon or Venus by making real-time telescopic observations. Students also receive an introduction to the Observatory, an opportunity to perform an activity relating to Galileo's observations, and an interview with an astronomer. A website provides teachers pre-and post-video conference materials, instructions, and a certificate of completion that can be customized for each student. The website also lists content alignment with state science education standards.

Astronomy Teacher Training: Towards Year 2009

The Direccion General de Divulgacion de la Ciencia is part of Mexico's National University; its purpose is science outreach. Most of its activities are dedicated to school level audiences; nevertheless due to the speed of science development, courses are given for teachers. The astronomy curricula includes: new results in astronomy research, general astrophysics and tools to teach astronomy. The courses offer twelve two hour long sessions. An astronomy researcher delivers a lecture and teachers are trained to use hands on activity. Beginning last in 2007 it has focused on Galileo. It addressed the way he was modern scientist, he observed and made experiments and wrote his results in common language. Year 2009 is a perfect incentive to carry out activities with teachers and keep them busy organizing telescope construction and observations during and after Galileo's commemoration. A book was written specially for them on the experiments Galileo made. In this book they can find interesting hand-on activities with materials that are readily available. (Los experimentos de Galileo, Silvia Torres y Consuelo Doddoli, Correo del Maestro, 2008, in press.) The magazine Correo del Maestro holds many articles written by the author on astronomical activities aimed to teachers.

Astronomy in the society and culture of Estonia

History and present state of astronomy in a small North-Eastern European country are considered. There is a rather big number (about 35) of professional astronomers in Estonia, including 21 IAU members. Through some outstanding persons, astronomy in Estonia has significant relations with the society. The same can be said about the culture. Well-developed astronomy has contributed into the cooperation of Estonia with the European Space Agency, and thus, has an indirect effect to the country's economy.

Astronomy Village: Innovative Uses of Planetary Astronomy Images and Data

NASA Astrophysics Data System (ADS)

Croft, S. K.; Pompea, S. M.

2008-06-01

Teaching and learning science is best done by hands-on experience with real scientific data and real scientific problems. Getting such experiences into public and home-schooling classrooms is a challenge. Here we describe two award-winning multimedia products that embody one successful solution to the problem: Astronomy Village: Investigating the Universe, and Astronomy Village: Investigating the Solar System. Each Village provides a virtual environment for inquiry-based scientific exploration of ten planetary and astronomical problems such as ``Mission to Pluto'' and ``Search for a Supernova.'' Both Villages are standards-based and classroom tested. Investigating the Solar System is designed for middle and early high school students, while Investigating the Universe is at the high school and introductory college level. The objective of both Villages is to engage students in scientific inquiry by having them acquire, explore, and analyze real scientific data and images drawn from real scientific problems.

Remeasurement of the H I Gunn-Peterson Effect toward QSO PKS 1937-101 with Keck Observations

NASA Astrophysics Data System (ADS)

Fang, Yihu; Fan, Xiaoming; Tytler, David; Crotts, Arlin P. S.

1998-04-01

We present the first measurement of the H I Gunn-Peterson effect using the Keck 10 m telescope, observing the high-redshift QSO PKS 1937-101 (z = 3.787). The high-resolution echelle (HIRES) spectra, with FWHM ~15 km s-1 and a signal-to-noise ratio (S/N) ~50 per spectral resolution element, allows us to resolve many weak lines down to NH I = 1012 cm-2, thus reducing the line-blanketing problem compared with previous data. Based on intensity-distribution analysis, we find that a maximum likelihood best fit yields a Gunn-Peterson type of opacity τGP = 0.113 +/- 0.020 in addition to a power-law Lyα absorption-line population with β of 1.7 down to NH I = 1012 cm-2. There remains systematic uncertainty in this result because of problems extrapolating the spectral continuum from the red side of the Lyα emission line. This is consistent with the previous study of the same QSO in low S/N data using weighted intensity function analysis (Fang & Crotts 1995). It indicates that this previous method succeeds in measuring the Lyα forest continuum level at low S/N, which is essential in extending the technique to possible fainter QSOs with minimum emission-line contamination for reliable continuum extrapolation. We further discuss problems of severe line blanketing, even in Keck spectra for QSOs at z >= 4.5, and show the effectiveness of the weighted intensity function method in measuring continuum levels in extremely crowded Lyα absorption spectra for redshifts as high as z > 5.

Interdisciplinary Approaches to Astronomy: Cosmic Fiction, Drama and Poetry

NASA Astrophysics Data System (ADS)

Fraknoi, A.

2015-09-01

I have spent four decades teaching introductory astronomy to university students whose primary subject of study is not astronomy, as well as developing activities to help the public appreciate astronomical ideas and developments. One of the more effective tools that I have found for capturing the interest of non-scientists has been approaching astronomy through its influence on the humanities. In this article I examine some examples of astronomical inspiration in the humanities, looking at plays, poetry and fiction. A second paper, devoted to music inspired by astronomy, will appear in a future issue of the CAPjournal.

Rhoads, James E.; Xu, Chun; Dawson, Steve; Dey, Arjun; Malhotra, Sangeeta; Wang, JunXian; Jannuzi, Buell T.; Spinrad, Hyron; Stern, Daniel

2004-08-01

We present a redshift z=6.535 galaxy discovered by its Lyα emission in a 9180 Å narrowband image from the Large Area Lyman Alpha survey. The Lyα line luminosity (1.1×1043 ergs s-1) is among the largest known for star-forming galaxies at z~6.5. The line shows the distinct asymmetry that is characteristic of high-redshift Lyα. The 2 σ lower bound on the observer-frame equivalent width is greater than 530 Å. This is hard to reconcile with a neutral intergalactic medium (IGM) unless the Lyα line is intrinsically strong and is emitted from its host galaxy with an intrinsic Doppler shift of several hundred km s-1. If the IGM is ionized, it corresponds to a rest-frame equivalent width greater than 40 Å after correcting for Lyα forest absorption. We also present a complete spectroscopic follow-up of the remaining candidates with line flux greater than 2×10-17 ergs cm-2 s-1 in our 1200 arcmin2 narrowband image. These include another galaxy with a strong emission line at 9136 Å and no detected continuum flux, which, however, is most likely an [O III] λ5007 source at z=0.824, on the basis of a weak detection of the [O III] λ4959 line. The data presented in this paper were obtained at the Kitt Peak National Observatory, the Gemini Observatory, and the W. M. Keck Observatory. Kitt Peak National Observatory, National Optical Astronomy Observatory, is operated by the Association of Universities for Research in Astronomy, Inc. (AURA), under cooperative agreement with the National Science Foundation (NSF). The Gemini Observatory is operated by AURA under a cooperative agreement with the NSF on behalf of the Gemini partnership: the NSF (United States), the Particle Physics and Astronomy Research Council (United Kingdom), the National Research Council (Canada), CONICYT (Chile), the Australian Research Council, CNPq (Brazil), and CONICET (Argentina).

This article describes the experience of attending the European Southern Observatory (ESO) Astronomy Camp from the perspective of its participants - students aged between 16 and 18 years old from around the world. The students shared a week together during the winter of 2014 in the Alpine village of Saint-Barthelemy, Italy. The camp was organised by ESO in collaboration with Sterrenlab and the Astronomical Observatory of the Autonomous Region of the Aosta Valley and offered a rich programme of astronomy and leisure activities. This article focuses on the concept of astronomy camps, and their role as a unique tool to complement formal classroom education, rather than on the astronomy activities and the scientific programme. Thus, it is not an academic review of the implemented methodologies, but rather a reflection on the overall experience. The article was brought together from collaborative accounts by some of the participants who were asked to reflect on the experience. The participants who contributed to this article represent the diversity of the ESO Astronomy Camp's alumni community.

Astronomy Instruction at a Two-year Technical College

NASA Astrophysics Data System (ADS)

Sirola, C. J.

2000-12-01

Over half of all students now begin their college careers at two-year institutions (technical colleges, junior colleges, vocational schools, etc.). This shift in student demographics has broad implications for college-level science instruction, including astronomy instruction. We compare astronomy instruction at two-year institutions to that at traditional four-year universities. A typical two-year school like Tri-County Technical College profers challenges not typically faced by research universities such as lack of research funding, little equipment or facilities, and a generally lower level of student ability. Conversely, a Tri-County Tech offers opportunities such as extensive training in teaching methodologies, a wide range of student demographics, and small classroom sizes. Our students are rarely interested in astronomy as a major, but instead take astronomy to fulfill other major requirements or to ensure the transfer of science credits to four-year universities. We present several examples of astronomy instruction at Tri-County Technical College and discuss our philosophy of teaching in a post-secondary environment whose enrollment is on the rise.

Astronomy for a Better World: IAU OAD Task Force-1 Programs for Advancing Astronomy Education and Research in Universities in Developing Countries

NASA Astrophysics Data System (ADS)

Guinan, Edward; Kolenberg, Katrien

2015-03-01

We discuss the IAU Commission 46 and Office for Astronomy Development (OAD) programs that support advancing Astronomy education and research primarily in universities in developing countries. The bulk of these operational activities will be coordinated through the OAD's newly installed Task Force 1. We outline current (and future) IAU/OAD Task Force-1 programs that promote the development of University-level Astronomy at both undergraduate and graduate levels. Among current programs discussed are the past and future expanded activities of the International School for Young Astronomers (ISYA) and the Teaching Astronomy for Development (TAD) programs. The primary role of the ISYA program is the organization of a three week School for students for typically M.Sc. and Ph.D students. The ISYA is a very successful program that will now be offered more frequently through the generous support of the Kavli Foundation. The IAU/TAD program provides aid and resources for the development of teaching, education and research in Astronomy. The TAD program is dedicated to assist countries that have little or no astronomical activity, but that wish to develop or enhance Astronomy education. Over the last ten years, the ISYA and TAD programs have supported programs in Africa, Asia, Central America and the Caribbean, the Middle East, South East and West Asia, and South America. Several examples are given. Several new programs being considered by OAD Task Force-1 are also discussed. Other possible programs being considered are the introduction of modular Astronomy courses into the university curricula (or improve present courses) as well as providing access to ``remote learning`` courses and Virtual Astronomy labs in developing countries. Another possible new program would support visits of astronomers from technically advanced countries to spend their sabbatical leaves teaching and advising University Astronomy programs in developing countries. Suggestions for new Task Force -1

Introducing the Virtual Astronomy Multimedia Project

Wyatt, Ryan; Christensen, L. L.; Gauthier, A.; Hurt, R.

2008-05-01

The goal of the Virtual Astronomy Multimedia Project (VAMP) is to promote and vastly multiply the use of astronomy multimedia resources—from images and illustrations to animations, movies, and podcasts—and enable innovative future exploitation of a wide variety of outreach media by systematically linking resource archives worldwide. High-quality astronomical images, accompanied by rich caption and background information, abound on the web and yet prove notoriously difficult to locate efficiently using existing search tools. The Virtual Astronomy Multimedia Project offers a solution via the Astronomy Visualization Metadata (AVM) standard. Due to roll out in time for IYA2009, VAMP manages the design, implementation, and dissemination of the AVM standard for the education and public outreach astronomical imagery that observatories publish. VAMP will support implementations in World Wide Telescope, Google Sky, Portal to the Universe, and 365 Days of Astronomy, as well as Uniview and DigitalSky software designed specifically for planetariums. The VAMP workshop will introduce the AVM standard and describe its features, highlighting sample image tagging processes using diverse tools—the critical first step in getting media into VAMP. Participants with laptops will have an opportunity to experiment first hand, and workshop organizers will update a web page with system requirements and software options in advance of the conference (see http://virtualastronomy.org/ASP2008/ for links to resources). The workshop will also engage participants in a discussion and review of the innovative AVM image hierarchy taxonomy, which will soon be extended to other types of media.

The Eternal Role of Astronomy in History and Civilization

NASA Astrophysics Data System (ADS)

Theodossiou, E.; Manimanis, V. N.

2010-07-01

Astronomy is the most ancient of all natural sciences. From its roots in ancient Babylonian and Egyptian stellar observations, and through its formulation into a science from the Greek natural philosophers, it defined the measurement of time. The stellar eras and the applications of Astronomy were incorporated in temples, paintings, sculptures and in art in general. Today, the value of Astronomy on practical matters, timekeeping or the navigation, has diminished. However, the eternal questions connected with Astronomy remain: Who are we and where did we come from? How and why was the Universe born? The greatest step to answer this kind of questions came with the so-called Copernican revolution, mostly in the 17th Century. The progress of Astronomy in the 400 years since then answered questions and gave an end to all kinds of superstitions, one more contribution to human civilization.

Ancient Chinese Astronomy - An Overview

NASA Astrophysics Data System (ADS)

Shi, Yunli

Documentary and archaeological evidence testifies the early origin and continuous development of ancient Chinese astronomy to meet both the ideological and practical needs of a society largely based on agriculture. There was a long period when the beginning of the year, month, and season was determined by direct observation of celestial phenomena, including their alignments with respect to the local skyline. As the need for more exact study arose, new instruments for more exact observation were invented and the system of calendrical astronomy became entirely mathematized.

Women's and men's career choices in astronomy and astrophysics

NASA Astrophysics Data System (ADS)

Ivie, Rachel

2017-01-01

In order to understand gender differences in persistence and attrition from astronomy and physics, the Longitudinal Study of Astronomy Graduate Students follows a cohort of people who were graduate students in astronomy or astrophysics during 2006-07. The first survey was conducted during 2007-08 and the second during 2012-13, when many of the respondents had left graduate school and were working. For respondents who had completed PhDs and were not postdocs, we tested the effects of four major concepts on attrition from physics and astronomy. These concepts included: the imposter syndrome, mentoring and advising during graduate school, work-family balance, and being female. We hypothesized that women would be more likely than men to work outside of astronomy and physics. However, results from the study show that there is no direct independent effect of being female on attrition. Rather, women are more likely to leave astronomy because they are more likely than men to (1) experience difficulties related to the need to find a job for a spouse or partner in the same geographical area, and (2) report less than satisfactory advising during graduate school. This research identifies specific areas of concern that can be addressed by the scientific community to increase the retention of all people, but especially women, in astronomy, physics, and related fields.

Keck Observations of the UV-Bright Star Barnard 29 in the Globular Cluster M13 (NGC 6205)

NASA Astrophysics Data System (ADS)

Dixon, William Van Dyke; Chayer, Pierre; Reid, Iain N.

2016-06-01

In color-magnitude diagrams of globular clusters, stars brighter than the horizontal branch and bluer than the red-giant branch are known as UV-bright stars. Most are evolving from the asymptotic giant branch (AGB) to the tip of the white-dwarf cooling curve. To better understand this important phase of stellar evolution, we have analyzed a Keck HIRES echelle spectrum of the UV-bright star Barnard 29 in M13. We begin by fitting the star's H I (Hα, Hβ, and Hγ) and He I lines with a grid of synthetic spectra generated from non-LTE H-He models computed using the TLUSTY code. We find that the shape of the star's Hα profile is not well reproduced with these models. Upgrading from version 200 to version 204M of TLUSTY solves this problem: the Hα profile is now well reproduced. TLUSTY version 204 includes improved calculations for the Stark broadening of hydrogen line profiles. Using these models, we derive stellar parameters of Teff = 21,100 K, log g = 3.05, and log (He/H) = -0.87, values consistent with those of previous authors. The star's Keck spectrum shows photospheric absorption from N II, O II, Mg II, Al III, Si II, Si III, S II, Ar II, and Fe III. The abundances of these species are consistent with published values for the red-giant stars in M13, suggesting that the star's chemistry has changed little since it left the AGB.

Using Computers in Introductory Astronomy Courses

NASA Astrophysics Data System (ADS)

Deming, Grace L.

1995-12-01

Computer literacy is fast becoming a focal point in undergraduate education. Scientific literacy has been a continuing goal of undergraduate programs across the nation and a course in introductory astronomy is often used to satisfy such science requirements. At U. MD an introduction to computer skills is being integrated into our astronomy curriculum for non-science majors. The campus is adequately equipped with computer labs, yet many students enter college without basic computer skills. In Astronomy 101 (General Astronomy) students are introduced to electronic mail, a Listserver, and the world wide web. Students in this course are required to register for a free campus computer account. Their first assignment is to use e-mail to subscribe to the class Listserver, Milkyway. Through Milkyway, students have access to weekly lecture summaries, questions to review for exams, and copies of previous exams. Using e-mail students may pose questions, provide comments, or exchange opinions using Milkyway, or they may e-mail the instructor directly. Studies indicate that using e-mail is less intimidating to a student than asking a question in a class of 200 students. Monitoring e-mail for student questions has not been a problem. Student reaction has been favorable to using e-mail, since instructor office hours are not always convenient, especially to commuting or working students. Through required assignments, students receive an introduction to accessing information on the world wide web using Netscape. Astronomy has great resources available on the Internet which can be used to supplement and reinforce introductory material. Assignments are structured so that students will gain the techniques necessary to access available information. It is hoped that students will successfully apply the computer skills they learn in astronomy class to their own fields and as life-long learners. We have found that students comfortable with computers are willing to share their knowledge

Elementary astronomy

Fierro, J.

2006-08-01

In developing nations such as Mexico, basic science education has scarcely improved. There are multiple reasons for this problem; they include poor teacher training and curricula that are not challenging for students. I shall suggest ways in which astronomy can be used to improve basic education, it is so attractive that it can be employed to teach how to read and write, learn a second language, mathematics, physics, as well as geography. If third world nations do not teach science in an adequate way, they will be in serious problems when they will try to achieve a better standard of living for their population. I shall also address informal education, it is by this means that most adults learn and keep up to date with subjects that are not their specialty. If we provide good outreach programs in developing nations we can aid adult training; astronomy is ideal since it is particularly multidisciplinary. In particular radio and television programs are useful for popularization since they reach such wide audiences.

The Astronomy Workshop (http://janus.astro.umd.edu) is a collection of interactive online educational tools developed for use by students, educators, and the general public. The more than 20 tools in the Astronomy Workshop are rated for ease-of-use, and have been extensively tested in large university survey courses, classes for undergraduate majors, and High Schools. Here we briefly describe a few of the more popular tools. The Life of the Sun (New!): The history of the Sun is animated as a movie, showing students how the size and color of our star has evolved and will evolve in time. Animated Orbits of Planets and Moons: The orbital motions of planets, moons, asteroids, and comets are animated at their correct relative speeds in accurate to-scale drawings. Solar System Collisions: This most popular of our applications shows what happens when an asteroid or comet with user-defined size and speed impacts a given planet. The program calculates many effects, including the country of impact (if Earth is the target), energy of explosion, crater size, and magnitude of the ``planetquake'' generated. It also displays a relevant image (e.g. terrestrial crater, lunar crater, etc.). Astronomical Distances: Travel away from the Earth at a chosen speed and see how long it takes to reach other planets, stars and galaxies. This tool helps students visualize astronomical distances in an intuitive way. Funding for the Astronomy Workshop is provided by NSF.

A partnership has been established between South Carolina State University (SCSU, a Historically Black College/University), the National Optical Astronomy Observatory (NOAO) and Clemson University (CU) under an award from NSF's "Partnerships in Astronomy and Astrophysics Research and Education (PAARE)" program. The mission of POCA is to develop an effective, long-term partnership that combines the strengths of the three institutions to increase the scientific and educational output of all the partners with special emphasis on enhancing diversity in the field of astronomy. Components of the program include enhancing faculty and student research in astronomy at SCSU, recruiting and retaining underrepresented minority students into the field, outreach through planetarium programs and museum exhibits and developing web based resources in astronomy education. Activities in the first year of the program are discussed. We have begun developing and testing several new astronomy laboratory exercises. Our first summer internship program has concluded successfully. With PAARE scholarship money, we are now supporting four physics majors at SCSU who have chosen the astronomy option (concentration) for their degree. SCSU undergraduates have acquired observing experience on the KPNO Mayall 4-meter telescope under the guidance of faculty and graduate students from CU. NOAO astronomers have collaborated with SCSU faculty to begin a research program that studies RV Tauri stars. Funds from PAARE are supporting follow-up research to a just-completed doctoral dissertation by E. A. Mayo described elsewhere in these proceedings. Future plans for graduate fellowships and related activities are discussed in addition to summer internships for POCA undergraduates at CU and NOAO. Support for this work was provided by the NSF PAARE program to South Carolina State University under award AST-0750814.

My successful outreach program venues include: outdoor concerts and festivals; the US National Mall; churches, synagogues, seminaries, or clergy conferences; the Ronald McDonald Houses of Long Island and Chicago; the Winthrop U. Hospital Children’s Medical Center the Fresh Air Fund summer camps (low-income and special needs); a Halloween star party (costumed kids look through telescopes); a Super Bowl Star Party (targeting women); Science Festivals (World, NYC; Princeton U.; the USA Science and Engineering Festival); and the NYC Columbus Day Parade. Information was also provided about local science museums, citizen science projects, astronomy educational sites, and astronomy clubs to encourage lifelong learning. In 2010 I created Astronomy Festival on the National Mall (co-sponsored by the White House Office of Science and Technology Policy) with the participation of astronomy clubs, scientific institutions and with Tyco Brahe, Johannes Kepler, and Caroline Herschel making guest appearances. My programs include solar, optical, and radio telescope observations, hands-on activities, a live image projection system; large outdoor posters and banners; videos; hands-on activities, and edible astronomy demonstrations.My NASA-funded Music and Astronomy Under the Stars (MAUS) program (60 events 2009 - 2013) reached 50,000 music lovers at local parks and the Central Park Jazz, Newport Folk, Ravinia, or Tanglewood Music Festivals with classical, folk, pop/rock, opera, Caribbean, or county-western concerts assisted by astronomy clubs. Yo-Yo-Ma, the Chicago and Boston Symphony Orchestras, Ravi Coltrane, Esperanza Spalding, Phish, Blood Sweat and Tears, Deep Purple, Tony Orlando, and Wilco performed at these events. MAUS reached underserved groups and attracted large crowds. Young kids participated in this family learning experience - often the first time they looked through a telescope. While < 50% of the participants took part in a science activity in the past year, they

2014-01-01

The Albion College Astronomy Club has a bright and rich history, and an even more luminous future. The club has always been and continues to be rooted in educating club members, fellow undergraduates and the community about astronomy. Public observing events are held several times each year, with the support of physics faculty and astronomy club members. In the spring of 2013, the club built and launched its first model rocket. The building of rockets has expanded club membership, which will ensure the continuity of our astronomy club. Additionally, in the 2013-2014 academic year, we plan to work with the local science museum to educate after-school groups about constellations and how much fun can be had observing, sans telescope. All of these activities culminate into a club that is integrative and educationally enriching.

Improving Education and Public Outreach Through Astronomy Education Research

NASA Astrophysics Data System (ADS)

Slater, Timothy F.

2005-04-01

Following in the footsteps of physics education research, the relatively new field of astronomy education research is already making dramatic improvements to the teaching and learning of astronomy. Whereas physics education research has focused predominantly on the introductory physics course, astronomy education is working on developing instruments and models to understand widely ranging domains that span K-12, undergraduate majors and non-majors, and even into the realms of public outreach. As one example, the repeated call for a more student-centered approach to teaching due to the ineffectiveness of lecture has been gaining prominence in the astronomy teaching community. At the beginning of a large-enrollment introductory astronomy survey course, we administered 68-multiple choice items as a pretest to 81 students. At the end of each lecture we administered the specific items related to that particular day's lecture a second time as a posttest. The pretest was 30% correct and the test, when given after lecture alone showed 52% correct. These results illustrate that instructor-centered strategies are largely ineffective at promoting meaningful conceptual gains. Alternatively, when using curriculum materials created from a basis of astronomy education research, we find that the posttest average score grows beyond 70%. Each 15-minute Lecture-Tutorial poses a carefully crafted sequence of conceptually challenging, Socratic-dialogue driven questions, along with graphs and data tables, all designed to encourage students to reason critically about difficult concepts in astronomy. A significant effort was focused on carefully evaluating changes in students' conceptual understanding and attitudes toward learning astronomy. The quantitative and qualitative results strongly suggest that the Lecture-Tutorials help students make significant conceptual gains.

Evolving Perspectives on Astronomy Education and Public Outreach in Hawai'i

NASA Astrophysics Data System (ADS)

Kimura, Ka'iu; Slater, T.; Hamilton, J.; Takata, V.

2012-01-01

For the last several decades, well meaning astronomers and educators have worked diligently to provide astronomy education experiences to Native Hawaiians and visitors across all the islands. Much of the early education and public outreach (EPO) work was based on a philosophical perspective based on the notion of, "if we just make them aware of how wonderful astronomy is, then everyone will naturally support the development of astronomy in the islands.” In support of this goal, numerous teacher workshops were delivered and the first generation of the Maunakea Observatories Visitors’ Center was developed and funded. These projects were most frequently developed using Mainland thinking, in a Mainland style, with a Mainland agenda. Consequently, these efforts often failed to create even moderate impacts, whether in educational settings, or in terms of public outreach. In recent years, our understanding of effective EPO has evolved. This evolution has led to a shift in the locus of control, from the Mainland to the Islands; and in content, from "astronomy only” to "astronomy as part of the whole.” We have come to understand that successfully transformative EPO requires intertwining astronomy with teaching about culture, language and context. In response, the `Imiloa Astronomy Center was expanded to convolve historical and modern astronomy with Hawaiian culture and language. Moreover, the most successful astronomy EPO programs in the islands have been redesigned to reflect meaningful collaborations of schools, businesses, and the larger community that situate astronomy as part of a larger educational work of honoring the traditions of the past while simultaneously transforming the future. This evolution in thinking may serve as a model for the astronomy community's interaction with other regional communities.

HUBBLE AND KECK DISCOVER GALAXY BUILDING BLOCK

NASA Technical Reports Server (NTRS)

2002-01-01

This NASA Hubble Space Telescope image shows a very small, faint galaxy 'building block' newly discovered by a unique collaboration between ground- and space-based telescopes. Hubble and the 10-meter Keck Telescopes in Hawaii joined forces, using a galaxy cluster which acts as gravitational lens to detect what scientists believe is one of the smallest very distant objects ever found. The galaxy cluster Abell 2218 was used by a team of European and American astronomers led by Richard Ellis (Caltech) in their systematic search for intrinsically faint distant star-forming systems. Without help from Abell 2218's exceptional magnifying power to make objects appear about 30 times brighter, the galaxy building block would have been undetectable. In the image to the right, the object is seen distorted into two nearly identical, very red 'images' by the gravitational lens. The image pair represents the magnified result of a single background object gravitationally lensed by Abell 2218 and viewed at a distance of 13.4 billion light-years. The intriguing object contains only one million stars, far fewer than a mature galaxy, and scientists believe it is very young. Such young star-forming systems of low mass at early cosmic times are likely to be the objects from which present-day galaxies have formed. In the image to the left, the full overview of the galaxy cluster Abell 2218 is seen. This image was taken by Hubble in 1999 at the completion of Hubble Servicing Mission 3A.

Urban Astronomy in the Philippines

NASA Astrophysics Data System (ADS)

Torres, Jesus Rodrigo F.

Astronomy in the Philippines is among the most interesting fields of study according to Filipino students. The science, however, suffers from neglect because most Philippine institutions of higher learning have campuses in urban areas. Common understanding dictates that satisfactory astronomical observations and studies can only be done at dark sites away from urban lights. This study aims to prove that astronomical work can be done even in light-polluted urban settings, and to convince educational policymakers to consider establishing observatories in urban campuses and to offer astronomy as a subject or major.

Teaching Astronomy with Podcasts of the APOD

NASA Astrophysics Data System (ADS)

Wagner, Robert M.

2017-01-01

The APOD website provides many excellent astronomy photos that are used to enhance introductory astronomy classes. For nearly six years, podcasts have been used to enhance learning in introductory astronomy classes at Harrisburg Area Community College. Daily 3-5 minute podcasts have been created and made available through iTunes to students in these classes at no charge. Students are asked to subscribe to the podcast collections and are quizzed on the images discussed throughout the semester. Because the images often focus on current findings in astronomy, the students are given instruction on findings that will not appear in their textbooks for several years. The students also receive a taste of some topics that may not be covered or that are just touched upon because of time limits in the classes. The podcasts have been used successfully with both traditional and fully online classes. The use of the podcasts enhances mobile learning as students can download and listen to the podcasts on their smartphones or tablets at their convenience. The student response to the podcasts has been excellent with some students noting that they continue to follow the website and podcasts even after they have completed the class. With mobile learning expanding, this is an excellent way to reach students and encourage them to further research the various topics in astronomy that are covered in the APOD images.

During the last decade of twentieth century astronomical articles in Thai scientific magazines were out of date. Interacting galaxies blackholes and other celestial objects beyond solar system were hardly found. While a pocket book for deep space was purposefully written by a lecturer a website of astronomy for Thais was planned by the cooperation of two computer programmers. An obseravatory with 600-mm reflector was the first attempt by a Thai engineer. The product of the first 150-mm reflector Dosonian made in Thailand is sold in low price. Future optical programs are now being planned to be made by Thais. These people have recently worked together to develope astronomy in Thailand.

Differences between US Women’s and Men’s Careers in Astronomy: Results from the Longitudinal Study of Astronomy Graduate Students

Ivie, Rachel; White, Susan; Chu, Raymond Y.

2015-08-01

The Longitudinal Study of Astronomy Graduate Students (LSAGS), a joint project of the American Astronomical Society (AAS) and the American Institute of Physics (AIP), emerged from the Women in Astronomy II conference held in Pasadena, CA, USA in 2003. At the conference, concern about possible differential attrition for women arose from the relatively high percentage of female junior (student) AAS members compared to the lower representation of women among astronomy faculty members.The Committee for the Status of Women in Astronomy (CSWA) and the AAS Council concluded that a longitudinal study was needed to collect data about which variables affect career choices in astronomy and to determine whether any of these variables exert a disproportionate force on either sex. In 2007-08, the project team, under the direction of Rachel Ivie, Associate Director of AIP’s Statistical Research Center (SRC), asked all graduate students in astronomy and astrophysics in the US (~1500) to complete the first survey. The LSAGS follows this same group of students as they leave graduate school and enter their careers. In 2012-13, more than 800 responded to the second survey, and most had completed PhDs. We plan a third round of data collection in 2015.Results from the study show that there are statistically significant differences between women and men in dissertation research methods, PhD subfield, and ratings of graduate school advisors. We found that after graduate school, women were more likely than men to take a break from work of six months or longer and to have made accommodations for a partner’s career opportunities (the “two-body problem”). In turn, women were more likely to work outside the field of astronomy because they were more likely to have experienced the “two-body problem.” In addition, we found women were more likely than men to have experienced harassment or discrimination at school or work. Finally, even while controlling for employment sector and years

A case study in adaptable and reusable infrastructure at the Keck Observatory Archive: VO interfaces, moving targets, and more

The Keck Observatory Archive (KOA) (https://koa.ipac.caltech.edu) curates all observations acquired at the W. M. Keck Observatory (WMKO) since it began operations in 1994, including data from eight active instruments and two decommissioned instruments. The archive is a collaboration between WMKO and the NASA Exoplanet Science Institute (NExScI). Since its inception in 2004, the science information system used at KOA has adopted an architectural approach that emphasizes software re-use and adaptability. This paper describes how KOA is currently leveraging and extending open source software components to develop new services and to support delivery of a complete set of instrument metadata, which will enable more sophisticated and extensive queries than currently possible. In August 2015, KOA deployed a program interface to discover public data from all instruments equipped with an imaging mode. The interface complies with version 2 of the Simple Imaging Access Protocol (SIAP), under development by the International Virtual Observatory Alliance (IVOA), which defines a standard mechanism for discovering images through spatial queries. The heart of the KOA service is an R-tree-based, database-indexing mechanism prototyped by the Virtual Astronomical Observatory (VAO) and further developed by the Montage Image Mosaic project, designed to provide fast access to large imaging data sets as a first step in creating wide-area image mosaics (such as mosaics of subsets of the 4.7 million images of the SDSS DR9 release). The KOA service uses the results of the spatial R-tree search to create an SQLite data database for further relational filtering. The service uses a JSON configuration file to describe the association between instrument parameters and the service query parameters, and to make it applicable beyond the Keck instruments. The images generated at the Keck telescope usually do not encode the image footprints as WCS fields in the FITS file headers. Because SIAP

Online Scholarly Conversations in General Education Astronomy Courses

NASA Astrophysics Data System (ADS)

Cai, Qijie; Wong, Ka-Wah

2018-01-01

In general education astronomy courses, many students are struggling with understanding the foundational concepts and theories in astronomy. One of the possible reasons is that, due the large class size, many of the courses are taught using a lecture mode, where human interactions and active learning are limited (Freeman et al., 2014). To address this challenge, we have applied the knowledge building framework (Scardamalia & Bereiter, 2006) to design an online collaborative learning component, called Scholarly Conversations, to be integrated into a general education astronomy course at a public, comprehensive university.During Scholarly Conversations, students are treated as scholars to advance knowledge frontiers (Scardamalia & Bereiter, 2006). The whole process involves the creation of new ideas and requires discourse and collective work for the advancement and creation of artifacts, such as theories and models (van Aalst, 2009). Based on the knowledge building principles (Scardamalia, 2002; Zhang, Scardamalia, Reeve, & Messina, 2009), several features have been built into Scholarly Conversations so that students are guided to deepen understanding of the astronomy concepts through three phases: knowledge sharing, knowledge construction and knowledge building, and reflections on learning growth (van Aalst, 2009; Cai, 2017). The online Scholarly Conversation is an extension of the lecture component of the general education astronomy course. It promotes student interactions and collaborative learning, and provides scaffolds for students to construct meanings of the essential concepts in astronomy through social learning and online technology. In this presentation, we will explain the specific design principles of the online Scholarly Conversation, and share the artifacts created to facilitate the online conversations in an general education astronomy course.Note: This project has been supported by the College of Education Research Grant Program at Minnesota State

The Cambridge Illustrated History of Astronomy

NASA Astrophysics Data System (ADS)

Hoskin, Michael

Expertly written and lavishly illustrated, The Cambridge Illustrated History of Astronomy offers a unique account of astronomical theory and practice from antiquity to the present day. How did Moslems of the Middle Ages use astronomy to calculate the direction of Mecca from far-flung corners of the Islamic world? Who was the only ancient Greek to suspect that the earth might revolve around the sun? How did Christopher Columbus abuse his knowledge of a lunar eclipse predicted by an astronomical almanac? Packed with anecdotes and intriguing detail, this book describes how we observed the sky and interpreted what we saw at different periods of history; how this influenced our beliefs and mythology; and how great astronomers contributed to what we now know. The result is a lively and highly visual history of astronomy - a compelling read for specialists and non-specialists alike.

Astronomy clubs constitute a “marching army” of knowledgeable, experienced astronomy enthusiasts deployed in a national network: an important resource for engaging the public through educational outreach events and activities. The Astronomical Society of the Pacific (ASP) in partnership with the Institute for Learning Innovation (ILI) and Inverness Research, Inc., has been engaged in a multi-year NSF-supported project focusing on this network and its potential to advance astronomy education and outreach. The project has explored the culture of astronomy clubs, identified impediments to building cultures of outreach within clubs, and developed and introduced new mechanisms to overcome these impediments and enhance clubs' abilities to encourage and sustain cultures that value and promote outreach efforts. This paper shares initial research, development and evaluation findings of the project, and describes ongoing supplemental efforts that continue to advance project objectives.

Expectations of Students about Astronomy in High School

Peixoto, Denis Eduardo; Kleinke, Maurício Urban

2016-12-01

Current literature reports that the astronomy education is motivating and interesting for basic education, but the content suggested by the national curriculum guidelines do not seem to attract students and teachers in order to transcend the discipline of Science in the elementary School or Physics in High School. By applying a questionnaire to 80 students of High School and participants of Brazilian Olympiad of Astronomy and Astronautics of two schools of São Paulo state, we obtained results that indicate that astronomy topics that really motivate students are topics linked to science fiction and current research, which are the subject of extensive media release and have a strong interdisciplinary character. At the end of the work we suggest a new context for astronomy education, by inserting topics combined with other areas of knowledge to what we call “interdisciplinary astrophysics teaching”.

Although astronomy is considered one of the older sciences of mankind, its teaching in basic education is facing problems. It is the school responsibility the dissemination of correct scientific concepts, including those related to Astronomy. This study was conducted at the Federal Institute of Education, Science and Technology of Santa Catarina, Campus Araranguá. In this article, we aimed to present the activities developed to help the formation of teachers, training undergraduate students in Natural Sciences with specialization in Physics to contribute to the dissemination and improvement of the teaching-learning of Astronomy. This paper presents the process and results of the evaluation of that training program. Analyses of the activity from the perspective of the participants are indicated and additional considerations are made regarding its use as a resource for teaching Astronomy and for teacher training.

Early years of Radio Astronomy in the U.S.

NASA Astrophysics Data System (ADS)

Burke, B. F.

Radio Astronomy in the U.S. went through two distinct phases, the pioneering phase before the Second World War, when Karl Jansky and Grote Reber were the only two radio astronomers in the world, and the post-WWII era, when the subject blossomed throughout the world, especially in England and Australia, while U.S. radio astronomy languished at a relatively low level, until its resurgence a decade later. Here in Budapest we are celebrating the 70th anniversary of Jansky's discovery, and I shall start with a review of his work, and the subsequent work of Grote Reber, who died, regrettably, in December 2002. Two historical references will be cited frequently: Serendipitous Discoveries in Radio Astronomy (Kellermann & Sheets, eds. 1983, referred to as Paper 1) and the two historical collections edited by W.T. Sullivan, Classics in Radio Astronomy (1982, referred to as Paper 2) and The Early Years of Radio Astronomy (1984, Paper 3).

Stunning imagery helps make astronomy one of the most popular sciences -- but what types of astronomy images are most popular? To help answer this question, public response to images posted to various public venues of the Astronomy Picture of the Day (APOD) are investigated. APOD portals queried included the main NASA website and the social media mirrors on Facebook, Google Plus, and Twitter. Popularity measures include polls, downloads, page views, likes, shares, and retweets; these measures are used to assess how image popularity varies in relation to various image attributes including topic and topicality.

C3R2 - Complete Calibration of the Color-Redshift Relation: Keck spectroscopy to train photometric redshifts for Euclid and WFIRST

NASA Astrophysics Data System (ADS)

Stern, Daniel; C3R2 Team

2017-01-01

A primary objective of both WFIRST and Euclid is to provide a 3D map of the distribution of matter across a significant fraction of the universe from the weak lensing shear field, but to do so requires robust distances to billions of galaxies. I will report on a multi-semester program, expected to total approximately 40 nights with Keck over the next two years. This program, supporting both the NASA PCOS and COR science goals, will obtain the necessary galaxy spectroscopy to calibrate the color-redshift relation for the Euclid mission, and make significant progress towards the WFIRST requirements. The program, called C3R2 or Complete Calibration of the Color-Redshift Relation, already encompasses 10 allocated nights of NASA Keck Key Strategic Mission Support (PI D. Stern), 12 allocated nights from Caltech (PI J. Cohen), 3 allocated nights from the University of Hawaii (PI D. Sanders), and 1.5 allocated nights from UC-Riverside (PI B. Mobasher). We are also pursuing opportunities at additional 8- to 10-meter class telescopes, including Magellan, VLT and GCT. I will present the motivation for this program, the plans, and current results.

The Black Hole Masses and Star Formation Rates of z>1 Dust Obscured Galaxies: Results from Keck OSIRIS Integral Field Spectroscopy

NASA Astrophysics Data System (ADS)

Melbourne, J.; Peng, Chien Y.; Soifer, B. T.; Urrutia, Tanya; Desai, Vandana; Armus, L.; Bussmann, R. S.; Dey, Arjun; Matthews, K.

2011-04-01

We have obtained high spatial resolution Keck OSIRIS integral field spectroscopy of four z ~ 1.5 ultra-luminous infrared galaxies that exhibit broad Hα emission lines indicative of strong active galactic nucleus (AGN) activity. The observations were made with the Keck laser guide star adaptive optics system giving a spatial resolution of 0farcs1 or <1 kpc at these redshifts. These high spatial resolution observations help to spatially separate the extended narrow-line regions—possibly powered by star formation—from the nuclear regions, which may be powered by both star formation and AGN activity. There is no evidence for extended, rotating gas disks in these four galaxies. Assuming dust correction factors as high as A(Hα) = 4.8 mag, the observations suggest lower limits on the black hole masses of (1-9) × 108 M sun and star formation rates <100 M sun yr-1. The black hole masses and star formation rates of the sample galaxies appear low in comparison to other high-z galaxies with similar host luminosities. We explore possible explanations for these observations, including host galaxy fading, black hole growth, and the shut down of star formation.

Southern Africa Regional Office of Astronomy for Development: A New Hub for Astronomy for Development

2015-08-01

A new Astronomy for Development hub needs innovative tools and programs. SAROAD is developing exciting tools integrating Raspberry Pi® technology to bring cost-effective astronomy content to learning centres. SAROAD would also like to report achievements in realising the IAU's strategic plan. In order to manage, evaluate and coordinate regional IAU capacity building programmes, including the recruitment and mobilisation of volunteers, SAROAD has built an intranet that is accessible to regional members upon request. Using this resource, regional members can see and participate in regional activities. This resource also forms the foundation for closer collaboration between SAROAD member countries. SAROAD has commenced with projects in the three Task Force areas of Universities and Research, Children and Schools and Public Outreach. Under the three Task Force areas, a total of seven projects have commenced in Zambia. A further two projects involve the collaboration of Zambia and other regional member countries in order to foster engagement with important regional astronomy facilities (e.g. SKA). SAROAD has identified the IAU’s International Year of Light and a starting point for offering regional support for IAU-endorsed global activities. SAROAD has set up a hub dedicated to regional events and activities about the International Year of Light. SAROAD has a database of regional authorities to enable contact with the region's decision makers and experts. SAROAD will hold an annual event which brings forum for astronomy for development. The creation of the database and the SAROAD Road show is a first step towards this goal. The SAROAD website has helped to advertise upcoming events for astronomy development and education; it is used to provide advice, guidance and information for astronomers in all countries in the Southern Africa. Fundraising is the primary goal for SAROAD in 2015 towards financial self-sufficiency by 2020. We report on the methods that work best

EU/ESO Workshop for European Physics Teachers A joint Workshop of the European Union (EU) and the European Southern Observatory (ESO) will take place on November 25 - 30, 1994 under the auspices of the European Week for Scientific Culture. The Workshop is entitled "Astronomy: Science, Culture and Technology". It will bring together at the ESO Headquarters in Garching (Germany) more than 100 secondary school teachers and ministerial representatives from 17 European countries to discuss all aspects of this broad subject. It is the first and very visible part of a new, sustained effort to stimulate and modernize the teaching of the subjects of Astronomy and Astrophysics in European secondary schools. During the Workshop, the participants will experience the present state of this multi-disciplinary science in its most general context, that is as a human, long-term scientific and technological endeavour with great cultural implications. They will exchange views on how the various elements of Astronomy can best be utilized within the educational schemes of the individual countries, both as subjects in their own rights, and especially in support of many other items on the present teaching agenda. Why This Workshop ? Astronomy is probably the oldest science. Since innumerable millenia, it has continued to have a great influence on mankind's perception of itself and its surroundings. In our days, Astronomy and Astrophysics have become a central area of the natural sciences with many direct links to other sciences (e.g., many aspects of physics, mathematics, chemistry, the geo-sciences, etc.); it has an important cultural content (including our distant origins, the recognition of the location and restricted extent of our niche in space and time, cosmological considerations as well as philosophy in general); its recent successes are to a large amount dependent on advanced technologies and methodologies (e.g., optics, electronics, detector techniques at all wavelengths

A Grand Vision for European Astronomy

NASA Astrophysics Data System (ADS)

2007-09-01

Today, and for the first time, astronomers share their global Science Vision for European Astronomy in the next two decades. This two-year long effort by the ASTRONET network of funding agencies, sponsored by the European Commission and coordinated by INSU-CNRS, underscores Europe's ascension to world leadership in astronomy and its will to maintain that position. It will be followed in just over a year by a prioritised roadmap for the observational facilities needed to implement the Vision. Implementation of these plans will ensure that Europe fully contributes to Mankind's ever deeper understanding of the wonders of our Universe. astronet logo "This is a great opportunity to help create a vibrant long-term future for astronomy and science" says Tim de Zeeuw (Leiden Observatory, The Netherlands) who led this community-wide effort. The ASTRONET Science Vision provides a comprehensive overview of the most important scientific questions that European astronomy should address in the next twenty years. The four key questions are the extremes of the Universe, from the nature of the dark matter and dark energy that comprise over 95% of the Universe to the physics of extreme objects such as black holes, neutron stars, and gamma-ray bursts; the formation of galaxies from the first seeds to our Milky Way; the formation of stars and planets and the origin of life; and the crucial question of how do we (and our Solar System) fit in the global picture. These themes reach well beyond the realm of traditional astronomy into the frontiers of physics and biology. The Vision identifies the major new facilities that will be needed to achieve these goals, but also stresses the need for parallel developments in theory and numerical simulations, high-performance computing resources, efficient astronomical data archiving and the European Virtual Observatory, as well as in laboratory astrophysics. "This report is a key input for the even more challenging task of developing a prioritised

Markishki, Pencho

The purpose of this report is the representation of a WEB-book, related to astronomy, astro-photography, optics and some additional areas that have direct practice for the amateur astronomers. The popularization of astronomy worldwide is the purpose of many amateur astronomers. It is interesting and maybe fascinated, requires often innovative solutions from the hobby star observers. Today it is possible to share the science information by different methods, using the modern information technologies - a possibility used by the amateur astronomers too. In Internet existing currently thousands of WEB- sites, related to astronomy, completed training programs developed by amateur astronomers are included. They are addressed often to the schools, to the hobby beginners or to the wide audience.

Astronomy Education: a Challenge for Contemporary Education

Tales around the World give visibility to local, national and international fundamental connection that always existed between people and the night sky that means Astronomy. In this paper we discuss and analyze further the role of Astronomy Education for achieving an integrated concept of education, one that enables individuals to adapt to a rapidly changing social, economic and cultural environment, and to continue to learn throughout life. It is no longer enough to learn how to read, write and count. We also discuss and present initiatives undertaken in the context of various national, and international educational projects in Greece as best practices on how Astronomy Education can actually reinforce the Contemporary Education.

Preservice elementary teachers learning of astronomy

NASA Astrophysics Data System (ADS)

Fidler, Chuck Gary

The dissertation presents a new approach for the study of preservice elementary teacher astronomy education. The approach suggests that learning astronomical concepts are facilitated by greater sophistication in scale perception and spatial-aptitude. This dissertation is underscored by the national call for elementary science education reform efforts and suggests certain strategies shown more effective for the development of accurate astronomical comprehension. The present research study describes how preservice elementary teachers conceptualize and communicate ideas about Space. Instead of assuming a universal mental conception of cosmic orientations and relationships, the dissertation claims that the perception of Space related dimensions vary among preservice elementary teachers. Furthermore, the dissertation suggests individual perceptions of the scale sizes and orientations of celestial systems have direct influences on mental models used to organize and communicate astronomical information. The development of inaccurate mental models of the scaled dimensions of Space may perpetuate the teacher-student cycle of misconception and naive-theory generation among children in elementary education settings. The ability to conceptualize the vast cosmos is facilitated by the minds ability to think about vast scales and orientations of celestial objects. The Earth-based perspective of astronomy education compels the learner to think about astronomical principles within imaginary frames of reference and across unfamiliar scaled dimensions. Therefore, mental astronomical model building is underscored by the perception of scale and cosmic spatiality. This study suggests these cognitive skill sets are interconnected and facilitate the learning of accurate astronomy principles; as well as play an important role when designing an astronomy education program for preservice elementary teachers. This research study is comprised of three separate standalone articles designed and

Capturing Public Interest in Astronomy through Art and Music

NASA Astrophysics Data System (ADS)

Sharma, M.; Sabraw, J.; Salgado, J. F.; Statler, T.; Summers, F.

2008-11-01

This is a summary of our 90-minute International Year of Astronomy (IYA) symposium workshop about engaging greater public interest in astronomy during the International Year of Astronomy 2009 through art and music. The session focused on: (i) plans for visually interesting and challenging astronomy presentations to connect with an audience at venues such as museums, concert halls, etc that might be apprehensive about science but open to creative experiences; (ii) the nuts-and-bolts of turning creative ideas into exhibits or visualizations; (iii) balancing scientific accuracy with artistic license; and (iv) how scientists, Education and Public Outreach (EPO) professionals, artists, musicians et al. can bridge the ``two cultures''---starting and sustaining multi-disciplinary collaborations, articulating expectations, and building synergy. The presenters shared with the EPO community some of the astronomy-art projects and resources that we have been developing for the IYA through a variety of collaborations. Our portfolios include state-of-the-art astronomy visualizations and tools, music videos and podcasts that highlight stunning images from NASA's Great Observatories; a video suite of astronomical images that can accompany live performances of Holst's The Planets and Mussorgsky's Pictures at an Exhibition; and SCALE, a multicomponent traveling art installation including the largest pastel drawing of the Milky Way.

X-ray and gamma ray astronomy detectors

NASA Technical Reports Server (NTRS)

Decher, Rudolf; Ramsey, Brian D.; Austin, Robert

1994-01-01

X-ray and gamma ray astronomy was made possible by the advent of space flight. Discovery and early observations of celestial x-rays and gamma rays, dating back almost 40 years, were first done with high altitude rockets, followed by Earth-orbiting satellites> once it became possible to carry detectors above the Earth's atmosphere, a new view of the universe in the high-energy part of the electromagnetic spectrum evolved. Many of the detector concepts used for x-ray and gamma ray astronomy were derived from radiation measuring instruments used in atomic physics, nuclear physics, and other fields. However, these instruments, when used in x-ray and gamma ray astronomy, have to meet unique and demanding requirements related to their operation in space and the need to detect and measure extremely weak radiation fluxes from celestial x-ray and gamma ray sources. Their design for x-ray and gamma ray astronomy has, therefore, become a rather specialized and rapidly advancing field in which improved sensitivity, higher energy and spatial resolution, wider spectral coverage, and enhanced imaging capabilities are all sought. This text is intended as an introduction to x-ray and gamma ray astronomy instruments. It provides an overview of detector design and technology and is aimed at scientists, engineers, and technical personnel and managers associated with this field. The discussion is limited to basic principles and design concepts and provides examples of applications in past, present, and future space flight missions.

Tatge, Coty B.; Slater, Stephanie J.; Slater, Timothy F.

2015-01-01

Our best efforts in the United States to dramatically improve teaching and learning in astronomy courses has been less than satisfactory despite Herculean efforts. A possible solution is to expand our view beyond our own culture's borders and presumptions in order to bring our shortcomings in discipline-based astronomy education research to light. Before we can begin the process of international comparisons of student conceptual understanding, we need to better understand how different citizens of different countries position astronomy culturally. Under the banner of the International STudy on Astronomy Reasoning Project, iSTAR, we are now carefully observing how foreign experts in teaching astronomy and the science of astronomy translate the Test Of Astronomy STandards - TOAST multiple-choice assessment instrument to look for subtle clues revealed during the translation process. The TOAST is the widely used standard to evaluate students' gains in the United States' Astronomy classrooms. We hope that the process of translation itself will help us comprehend how other cultures think differently about astronomical concepts and eventually we are looking to obtain useful data of how other cultures develop their society's understanding of particular astronomy aspects where we may fall short. Several of the iSTAR Project's bilingual speakers are documenting their thoughts and insights as they translate the TOAST. The end-goal is to collect a comprehensible, well-defined, and logical translation in various languages that are culturally sensitive and linguistically accurate. This project is sponsored and managed by the CAPER Center for Astronomy & Physics Education Research at CAPERTeam.com in collaboration with members of the International Astronomical Union-Commission 46.

Kinds of Astronomy-5

NASA Technical Reports Server (NTRS)

Ennico, Kimberly; DeVincenzi, D. (Technical Monitor)

2001-01-01

Astronomers study light and basically, almost everything we know about the universe has been figured out through the study of light gathered by telescopes on the earth, in the earth's atmosphere, and in space. This light comes in many different colors, the sum of which comprises what is commonly I known as the electromagnetic (EM) spectrum. Unfortunately, the earth's atmosphere blocks almost all of wavelengths in the EM spectrum. Only the visible (400-700 mn) and radio (approx. 1-150 m) "windows" are accessible from the ground, and thus have the longest observational "history." These early restrictions on the observational astronomer also gave rise to classifying "kinds" of astronomy based on their respective EM portion, such as the term "radio astronomy."

Public Outreach in Astronomy

Fierro, J.

2009-05-01

In this paper I will address ways in which astronomy can be conveyed to the general public. I believe that the workings of the cosmos are an effective way to interest the public in science due to their multidisciplinary nature and appeal. This paper is based on the idea that outreach is part of informal education and therefore must be encouraged since it is the way adults learn throughout their lives. We must take advantage of year 2009 to address astronomy in Galileo's honor. I think that outreach should be carried out in the way we enjoy learning about subjects outside our field of expertise. It must be done with passion and for the joy of giving; the gift that outreach conveys is knowledge.

The Colombian Association of Astronomical Studies (ACDA) is a Non Profit Organization with thirty years of permanent efforts for the popularization of astronomy and related sciences in Colombia. ACDA put together amateur and profesional astronomers, as well as interested people. We surely had left a footprint on uncountable number of attending people to our activities, members and former members, and have supported the process of building a new society, with more awareness on the importance of science. We devote our efforts to our members and general people, to keep them motivated, support them and follow each member own interests in order to expand and spread their knowledge. In order to achieve our goals we have develop several strategies as: acquire of didactic material and optical instruments, video projections and discussion, astronomical observations, visits to observatories and planetariums, attending conferences and events, and mainly a weekly Saturday morning talk at the Bogotá Planetarium. ACDA has had different study teams on several fields including: Planetary Systems, Astrobiology, Space Exploration, Cosmology, History of Astronomy and Radioastronomy. ACDA has a national brandname on Astronomy due to seriousness and quality of its projects. A good list of members have become profesional astronomers. From our experience we can say: astronomy is a fertile field to teach science, in general there is an absence of astronomy culture in the public, our best communication experience are astronomical observations, explained astronomy movies and colloquiums, our best public are kids and aged people and finally, social networks gave dynamics to our astronomy spreading initiative.

Volcanically active Io remains a mysterious and intriguing moon, despite numerous spacecraft flybys. Groundbased monitoring programs help characterize the time evolution of Io's volcanic activity, such as the frequency, spatial distribution and temperature of hot spots and outbursts. The satellite was observed intensively in December 2001 with the Keck II Adaptive Optics (AO) system and its recently installed near-infrared camera NIRC2. The spatial resolution after applying the MISTRAL myopic deconvolution method (130 km in K band and 200 km in L band) is better than that of the global images from the Galileo/NIMS instrument. A movie produced from 12 pictures taken every 30o in Ionian longitude provides a complete survey of Io's surface during one full rotation. A total of 26 active hot spots were detected in L band (3.8μ m), and approximatively three times more in M band (4.7μ m). One active hot spot is seen in K band (2.2μ m) in the Pele area. While Io is in Jupiter's shadow, it is invisible to the wavefront sensor, but its hot spots are easily visible in the near-infrared. We imaged Io during the 18 Dec. 2001 eclipse using Ganymede (30" from Io, moving relative to Io at 0.5"/min) as a reference source. Although isoplanatic effects limited AO performance, numerous spots are detected at both K' and L'. We will show the results of detailed studies (temperature, emission area, nature) for several of the hot spots. Keck Science team is composed of S. Kwok, P. Amico, R. Campbell, F. Chaffee, A. Conrad, A. Contos, B. Goodrich, G. Hill, D. Sprayberry, P. Stomski, P. Wizinowich (W.M. Keck Observatory).

The paper will discuss results from field testing these approaches.

Citizen Astronomy in China: An Overview

NASA Astrophysics Data System (ADS)

Ye, Quan-Zhi

2018-01-01

Citizen astronomers have benefited from technological advancements in the recent decades as they fill the scientific gaps left by professional astronomers, in the areas such as time domain observations, visual classification and data mining. Here I present an overview of the current status of citizen astronomy in China. Chinese citizen astronomers have made a visible contribution in the discoveries of new objects; however, comparing to their counterparts in the western world, they appear to be less interested in researches that do not involve making new discovery, such as visual classification, long-term monitoring of objects, and data mining. From a questionnaire survey that aimed to investigate the motivation of Chinese citizen astronomers, we find that this population is predominantly male (92%) who mostly reside in economically developed provinces. A large fraction (69%) of the respondents are students and young professionals younger than the age of 25, which differs significantly from the occupation and age distribution of typical Chinese Internet users as well as the user distribution of large international citizen science projects such as the Galaxy Zoo. This suggests that youth generation in China is more willing to participate citizen astronomy research than average generation. Additionally, we find that interests in astronomy, desire to learn new knowledges, have a fun experience and meet new friends in the community are all important driving factors for Chinese citizen astronomers to participate research. This also differs from their counterparts in western countries. With a large youth population that is interested in astronomy as well as a number of large astronomical facilities that are being planned or built, we believe that citizen astronomy in China has a vast potential. Timely and proper guidance from the professionals will be essential to help citizen astronomers to fulfill this potential.

Student comprehension of mathematics through astronomy

NASA Astrophysics Data System (ADS)

Search, Robert

The purpose of this study is to examine how knowledge of astronomy can enhance college-level learning situations involving mathematics. The fundamental symbiosis between mathematics and astronomy was established early in the 17th century when Johannes Kepler deduced the 3 basic laws of planetary motion. This mutually harmonious relationship between these sciences has been reinforced repeatedly in history. In the early 20th century, for example, astronomer Arthur Eddington used photographic evidence from a 1919 solar eclipse to verify Einstein's mathematical theory of relativity. This study was conducted in 5 undergraduate mathematics classes over the course of 2 years. An introductory course in ordinary differential equations, taught in Spring Semester 2013, involved 4 students. A similar course in Spring Semester 2014 involved 6 students, a Summer Semester 2014 Calculus II course involved 2 students, and a Summer 2015 Astronomy course involved 8 students. The students were asked to use Kepler's astronomical evidence to deduce mathematical laws normally encountered on an undergraduate level. They were also asked to examine the elementary mathematical aspects involved in a theoretical trajectory to the planet Neptune. The summer astronomy class was asked to draw mathematical conclusions about large numbers from the recent discoveries concerning the dwarf planet Pluto. The evidence consists primarily of videotaped PowerPoint presentations conducted by the students in both differential equations classes, along with interviews and tests given in all the classes. All presentations were transcribed and examined to determine the effect of astronomy as a generator of student understanding of mathematics. An analysis of the data indicated two findings: definite student interest in a subject previously unknown to most of them and a desire to make the mathematical connection to celestial phenomena.

Astronomy Courses which Emphasize Communication Skills

NASA Astrophysics Data System (ADS)

Dinerstein, H. L.

1998-12-01

The ability to communicate effectively, both in oral and written form, is crucial for success in almost any career path. Furthermore, being able to effectively communicate information requires a high level of conceptual mastery of the material. For these reasons, I have incorporated practice in communication into courses at a variety of levels, ranging from non-science-major undergraduate courses to graduate courses. I briefly describe the content of these courses, particularly the communication-related component. The first, Ast 309N, ``Astronomy Bizarre: Stars and Stellar Evolution," is an elective which follows one semester of general introductory astronomy for non-majors. Instead of homework problems, the students complete a sequence of writing assignments of graduated complexity, beginning with simple tasks such as writing abstracts and critiques of assigned readings, and moving on to writing term papers which require literature research and a short science fiction story incorporating accurate depictions of relativistic effects. In Ast 175/275, a ``Journal Club" course for upper-division astronomy majors, students read articles in the professional literature and give short oral presentations to the rest of the class. To build up their understanding of a topic, we work through the ``paper trail" of key papers on topics with exciting recent developments, such as extrasolar planets, gravitational lenses, or gamma-ray bursts. Finally, in a seminar course for first-semester astronomy graduate students (Ast 185C) that broadly addresses professional development issues, I include a practice AAS oral session, with the students giving 5-minute presentations on a journal paper of their choice. This seminar course also examines career paths and employment trends, the peer review process for papers and proposals, professional norms and ethics, and other topics. Syllabi for these and other courses I teach regularly can be found from my home page (http://www.as.utexas.edu/astronomy/people/dinerstein).

Test Of Astronomy STandards TOAST Survey of K-12 Teachers

NASA Astrophysics Data System (ADS)

Slater, Timothy F.; Slater, Stephanie; Stork, Debra J.

2015-01-01

Discipline-based education research in astronomy is focused on understanding the underlying mental mechanisms used by students when learning astronomy and teachers when teaching astronomy. Systematic surveys of K-12 teacher' knowledge in the domain of astronomy are conducted periodically in order to better focus and improve professional development. These surveys are most often done when doing contemporary needs assessments or when new assessment instruments are readily available. Designed by Stephanie J. Slater of the CAPER Center for Astronomy & Physics Education Research, the 29-item multiple-choice format Test Of Astronomy STandards - TOAST is a carefully constructed, criterion-referenced instrument constructed upon a solid list of clearly articulated and widely agreed upon learning objectives. The targeted learning concepts tightly align with the consensus learning goals stated by the American Astronomical Society - Chair's Conference on ASTRO 101, the American Association of the Advancement of Science's Project 2061 Benchmarks, and the National Research Council's 1996 National Science Education Standards. Without modification, the TOAST is also aligned with the significantly less ambitious 2013 Next Generation Science Standards created by Achieve, Inc., under the auspices of the National Research Council. This latest survey reveals that K-12 teachers still hold many of the same fundamental misconceptions uncovered by earlier surveys. This includes misconceptions about the size, scale, and structure of the cosmos as well as misconceptions about the nature of physical processes at work in astronomy. This suggests that professional development in astronomy is still needed and that modern curriculum materials are best served if they provide substantial support for implementation.

The Keck Aperture Masking Experiment: Dust Enshrouded Red Giants

NASA Technical Reports Server (NTRS)

Blasius, T. D.; Monnier, J. D.; Tuthill, P. G.; Danchi, W. C.; Anderson, M.

2012-01-01

While the importance of dusty asymptotic giant branch (AGB) stars to galactic chemical enrichment is widely recognised, a sophisticated understanding of the dust formation and wind-driving mechanisms has proven elusive due in part to the difficulty in spatially-resolving the dust formation regions themselves. We have observed twenty dust-enshrouded AGB stars as part of the Keck Aperture Masking Experiment, resolving all of them in multiple near-infrared bands between 1.5 m and 3.1 m. We find 45% of the targets to show measurable elongations that, when correcting for the greater distances of the targets, would correspond to significantly asymmetric dust shells on par with the well-known cases of IRC +10216 or CIT 6. Using radiative transfer models, we find the sublimation temperature of Tsub(silicates) = 1130 90K and Tsub(amorphous carbon) = 1170 60 K, both somewhat lower than expected from laboratory measurements and vastly below temperatures inferred from the inner edge of YSO disks. The fact that O-rich and C-rich dust types showed the same sublimation temperature was surprising as well. For the most optically-thick shells ( 2.2 m > 2), the temperature profile of the inner dust shell is observed to change substantially, an effect we suggest could arise when individual dust clumps become optically-thick at the highest mass-loss rates.

Making Astronomy Accessible

NASA Astrophysics Data System (ADS)

Grice, Noreen A.

2011-05-01

A new semester begins, and your students enter the classroom for the first time. You notice a student sitting in a wheelchair or walking with assistance from a cane. Maybe you see a student with a guide dog or carrying a Braille computer. Another student gestures "hello” but then continues hand motions, and you realize the person is actually signing. You wonder why another student is using an electronic device to speak. Think this can't happen in your class? According to the U.S. Census, one out of every five Americans has a disability. And some disabilities, such as autism, dyslexia and arthritis, are considered "invisible” disabilities. This means you have a high probability that one of your students will have a disability. As an astronomy instructor, you have the opportunity to reach a wide variety of learners by using creative teaching strategies. I will share some suggestions on how to make astronomy and your part of the universe more accessible for everyone.

Over the past three years, graduate students in the University of Virginia Astronomy Department (UVa) have partnered with the Central Virginia Governor's School for Science and Technology (CVGS) to advise high school juniors in individual astronomy research projects spanning eight months. CVGS, located 60 miles from UVa and servicing 14 schools in rural central VA, operates a daily, half-day program where talented high school juniors and seniors take courses in college-level science, mathematics, and technology, including research methods. UVa graduate students have mentored over a dozen students through astronomy research projects to fulfill their course requirements. The result of this unique partnership is the development of a full astronomy research curriculum that teaches the terminology, background concepts, analysis techniques and communication skills that are required for astronomy research, all designed for an off-site setting. The curriculum is organized into a set of "Tutorials,” which when combined with the standard CVGS Research and Statistics courses, result in an an effective, comprehensive, and productive research collaboration. In this poster, we will display our curriculum in a step by step basis as a model for potential collaborations with other institutions and comment on how these opportunities have benefited the high school students, CVGS and the graduate students involved.

IAU Astronomy for Equity and Inclusion Working Group

Ortiz-Gil, A.; García, B.; WG3 of Commission C1 Division C of the IAU

2017-03-01

In this talk we present the aims, goals and activities that have been started by the working group on Astronomy for Equity and Inclusion. This working group is part of Commission 1 ''Astronomy Education and Development'' of Division C ''Education, Outreach and Heritage'' of the International Astronomical Union (IAU). The working group was born with the aim of developing new strategies and resources to promote the access to Astronomy, both at the profesional and outreach levels, for persons with special needs or for those who could be excluded because of race or sexual orientation (among other reasons). It is composed of astronomers affiliated with the IAU and other volunteers who work in astronomy, education and special needs, as well as partner organizations like the IAU Office of Astronomy for Development (OAD), Astronomers without Borders (AWB), the Galileo Teacher Training Program (GTTP) or Universe Awareness (UNAWE). To reach those goals we have started different initiatives which are outlined at the working group’s website, like a repository of resources or the creation of a document about good practices, and the establishment of a tight collaboration with the Working Group about Accessibility of the American Astronomical Society, which was formed recently too.

Advances in astronomy are often enabled by adoption of new technology. In some instances this is where the technology has been invented specifically for astronomy, but more usually it is adopted from another scientific or industrial area of application. The adoption of new technology typically occurs via one of two processes. The more usual is incremental progress by a series of small improvements, but occasionally this process is disruptive, where a new technology completely replaces an older one. One of the activities of the OPTICON Key Technology Network over the past few years has been a technology forecasting exercise. Here we report on a recent event which focused on the more radical, potentially disruptive technologies for ground-based, optical and infrared astronomy.

Atanacković, Olga

2015-03-01

An overview of astronomy development in Serbia in view of the goals envisaged by the IAU Strategic Plan is given. Due attention is paid to the recent reform of education at all levels. In the primary schools several extra topics in astronomy are introduced in the physics course. Attempts are made to reintroduce astronomy as a separate subject in the secondary schools. Special emphasis is put to the role and activities of the Petnica Science Center the biggest center for informal education in SE Europe, and to a successful participation of the Serbian team in International astronomy olympiads. Astronomy topics are taught at all five state universities in Serbia. At the University of Belgrade and Novi Sad students can enroll in astronomy from the first study year. The students have the training at the Ondrejov Observatory (Czech Republic) and at the astronomical station on the mountain Vidojevica in southern Serbia. Astronomy research in Serbia is performed at the Astronomical Observatory, Belgrade and the Department of Astronomy, Faculty of Mathematics, University of Belgrade. There are about 70 researchers in astronomy in Serbia (and about as many abroad) who participate in eight projects financed by the Ministry of Education and Science and in several international cooperations and projects: SREAC, VAMDC, Belissima (recruitment of experienced expatriate researchers), Astromundus (a 2-year joint master program with other four European universities), LSST. One of the goals in near future is twinning between universities in the SEE region and worldwide. The ever-increasing activities of 20 amateur astronomical societies are also given.

Sharma, Mangala; Sabraw, J.; Salgado, J. F.; Statler, T. S.; Summers, F.

2008-05-01

Our 90-minute interactive panel and brainstorming session is about engaging greater public interest in astronomy during IYA 2009 through art and music. This session will focus on: (i) plans for visually interesting and challenging astronomy presentations (examples below) to connect with an audience at venues such as museums, concert halls, etc. that might be apprehensive about science but open to creative experiences (ii) ways to capitalize on interest generated through the arts to inspire lifelong appreciation of astronomy (iii) the nuts-and-bolts of turning creative ideas into exhibits or visualizations (iv) balancing scientific accuracy with artistic license (v) ways to publicize and disseminate programs at the interface of astronomy and the fine arts; and (vi) how scientists, E/PO professionals, artists, musicians et al. can bridge the "two cultures" - starting and sustaining multi-disciplinary collaborations, articulating expectations, and building synergy. The presenters will share with the E/PO community some of the astronomy-art projects and resources that we have been developing for the IYA through a variety of collaborations. Our portfolios include state-of-the-art astronomy visualizations and tools, music videos and podcasts that highlight stunning images from NASA's Great Observatories; a video suite of Solar System images that can accompany live performances of Holst's The Planets; and SCALE: a multicomponent traveling art installation including the largest pastel drawing of the Milky Way.

Astronomy Education and Teacher Training in Turkey

NASA Astrophysics Data System (ADS)

Kirbiyik, Halil

In this talk, education in astronomy and space sciences in schools in Turkey as well as activities to create awareness in these subjects will be discussed. A search done among youngsters(ages from 15 to 24) for measuring the scientific literacy showed that most attractive subjects to the Turkish younsters are “internet” and “astronomy”. This result led authorities to take necessary measures to fill the gap especially in teaching material such as books. Another attempt along this is to increase astronomy subjects in the school curricula. Besides TUBITAK National Observatory, universities and Turkish Astronomical Society are giving every efort to create public awareness of space activities and space sciences. As for the teacher training in astronomy and space sciences, much has been done but no success has come yet. Astronomy subjects, in schools, are generally taught not by astronomers but some other substitutes from other branches, such as physics and mathematics. Thus the Ministry of Education prefers training teachers in service. Nevertheless it must be stated that astronomers are pushing forward to formally have the right to train astronomers to become teachers to be hired by the Ministry of Education in schools.

Astronomy educators present the range of astronomy education programming available at the National Air and Space Museum, including the following. In the Phoebe Waterman Haas Public Observatory, visitors use telescopes and other scientific equipment to observe and discuss the Sun, Venus, and other celestial sights in an unstructured, inquiry-based environment. At Discovery Stations throughout the Museum, staff and volunteers engage visitors in hands-on exploration of a wide range of artifacts and teaching materials. Astronomy-related Discovery Stations include Cosmic Survey, an exploration of gravitational lensing using a rubber sheet, spectroscopy using discharge tubes, and several others. Astronomy lectures in the planetarium or IMAX theater, featuring researchers as the speakers, include a full evening of activities: a custom pre-lecture Discovery Station, a handout to help visitors explore the topic in more depth, and evening stargazing at the Public Observatory. Astronomy educators present planetarium shows, including star tours and explorations of recent science news. During Astronomy Chat, an astronomy researcher engages visitors in an informal conversation about science. The goal is to make the public feel welcome in the environment of professional research and to give busy scientists a convenient outreach opportunity. Astronomy educators also recruit, train, and coordinate a corps of volunteers who contribute their efforts to the programming above. The volunteer program has grown significantly since the Public Observatory was built in 2009.

A Coherent Content Storyline Approach for Introductory Astronomy

NASA Astrophysics Data System (ADS)

Palma, Christopher; Flarend, A.; McDonald, S.; Kregenow, J. M.

2014-01-01

The Earth and Space Science Partnership (ESSP) is a collaboration among Penn State scientists, science educators and seven school districts across Pennsylvania. Part of the multi-faceted ESSP effort includes revising the curriculum of university science classes known to be taken by large numbers of elementary pre-service teachers. By adopting research-based pedagogical approaches in our courses, we hope to expose these pre-service teachers to excellent examples of science teaching. In this presentation, we will discuss changes made in a pilot study to one section of our introductory astronomy survey course. There have been many articles published in the Astronomy Education Review and elsewhere that detail research-based pedagogical practices for introductory astronomy courses. Many of those practices (such as from the Center for Astronomy Education) have been incorporated into introductory astronomy courses at Penn State. However, our work with middle-grades teachers in the ESSP project is based on two key practices: a Claims, Evidence, and Reasoning (CER) framework (McNeill & Krajcik 2012) and a coherent science content storyline (Roth,et. al., 2011). As a first step in modeling these practices in our University courses, we reorganized our Astro course using a content storyline approach. We plan to incorporate CER activities into the course next year that advance the storyline described. In this poster, we present the storyline developed by our team, which we believe was successful in its pilot, and was built around a conceptually coherent presentation of the diverse set of phenomena typical of an introductory astronomy course. We adopted as our main learning goal a statement based on the cosmological principle that the physical laws throughout the Universe are identical everywhere. In addition, we organized the class schedule to connect the work done in each class to this storyline. We suggest that a coherent content storyline is a useful tool for others who

Critical Issues in the Philosophy of Astronomy and Cosmology

NASA Astrophysics Data System (ADS)

Dick, Steven J.

2016-01-01

Although the philosophy of science and of specific sciences such as physics, chemistry, and biology are well-developed fields with their own books and journals, the philosophy of astronomy and cosmology have received little systematic attention. At least six categories of problems may be identified in the astronomical context: 1) the nature of reasoning, including the roles of observation, theory, simulation, and analogy, as well as the limits of reasoning, starkly evident in the anthropic principle, fine-tuning, and multiverse controversies; 2) the often problematic nature of evidence and inference, especially since the objects of astronomical interest are for the most part beyond experiment and experience;3) the influence of metaphysical preconceptions and non-scientific worldviews on astronomy, evidenced, for example in the work of Arthur S. Eddington and many other astronomers; 4) the epistemological status of astronomy and its central concepts, including the process of discovery, the problems of classification, and the pitfalls of definition (as in planets); 5) the role of technology in shaping the discipline of astronomy and our view of the universe; and 6) the mutual interactions of astronomy and cosmology with society over time. Discussion of these issues should draw heavily on the history of astronomy as well as current research, and may reveal an evolution in approaches, techniques, and goals, perhaps with policy relevance. This endeavor should also utilize and synergize approaches and results from philosophy of science and of related sciences such as physics (e.g. discussions on the nature of space and time). Philosophers, historians and scientists should join this new endeavor. A Journal of the Philosophy of Astronomy and Cosmology (JPAC) could help focus attention on their studies.

A Keck/DEIMOS spectroscopic survey of faint Galactic satellites: searching for the least massive dwarf galaxies

NASA Astrophysics Data System (ADS)

Martin, N. F.; Ibata, R. A.; Chapman, S. C.; Irwin, M.; Lewis, G. F.

2007-09-01

We present the results of a spectroscopic survey of the recently discovered faint Milky Way satellites Boötes, Ursa Major I, Ursa Major II and Willman 1 (Wil1). Using the DEep Imaging Multi-Object Spectrograph mounted on the Keck II telescope, we have obtained samples that contain from ~15 to ~85 probable members of these satellites for which we derive radial velocities precise to a few kms-1 down to i ~ 21-22. About half of these stars are observed with a high enough signal-to-noise ratio to estimate their metallicity to within +/-0.2 dex. The characteristics of all the observed stars are made available, along with those of the Canes Venatici I dwarf galaxy that have been analysed in a companion paper. From this data set, we show that Ursa Major II is the only object that does not show a clear radial velocity peak. However, the measured systemic radial velocity (vr = 115 +/- 5kms-1) is in good agreement with simulations in which this object is the progenitor of the recently discovered Orphan Stream. The three other satellites show velocity dispersions that make them highly dark matter dominated systems (under the usual assumptions of symmetry and virial equilibrium). In particular, we show that despite its small size and faintness, the Wil1 object is not a globular cluster given its metallicity scatter over -2.0 <~ [Fe/H] <~ -1.0 and is therefore almost certainly a dwarf galaxy or dwarf galaxy remnant. We measure a radial velocity dispersion of only 4.3+2.3-1.3kms-1 around a systemic velocity of -12.3 +/- 2.3kms-1 which implies a mass-to-light ratio of ~700 and a total mass of ~5 × 105Msolar for this satellite, making it the least massive satellite galaxy known to date. Such a low mass could mean that the 107Msolar limit that had until now never been crossed for Milky Way and Andromeda satellite galaxies may only be an observational limit and that fainter, less massive systems exist within the Local Group. However, more modelling and an extended search for

An exemplary developing astronomy movement in Nepal

2015-03-01

Astronomy and space science education had been given least importance by Nepalese government in the past. The modern astronomy movement is believed to have started when an official observation programme of Haley's comet was organized by Royal Nepal Academy of Science and Technology (RONAST) in 1986. Following the huge pressure from the scientific community, the Nepal government (Kingdom of Nepal at that time) established B.P. Koirala Memorial Planetarium, Observatory and Science Museum Development Board in 1992. Initiatives of the project started with observatory set up and the development of astrophysics syllabus for university students. Astrophysics is included as an elective paper in the Physics masters course. The lead astrophysicist of Nepal Dr. Binil Aryal is running a research group in Tribhuvan University since 2005 which has a significant number of international publications. The developing government initiatives and achievements will be discussed. In 2007, a group of astronomy enthusiastic students along with amateurs working independently in past established Nepal Astronomical Society (NASO), which surprisingly increased the amateur activities and inspired other amateur groups to revive. During IYA 2009, more than 80 outreach and observation events were organized solely by NASO. NASO was able to collaborate with many international programmes and projects like GHOU/GTTP, EurAstro, AWB, UNAWE, SGAC, Star Peace, TWAN etc during and beyond IYA2009. Currently Nepal is recognized as the most eventful country of outreach and astronomy education among the amateur community. The success story of the astronomy movement and the local difficulties while organizing the events will be explained.

This triennium has seen a phenomenal investment in development of observational radio astronomy facilities in all parts of the globe at a scale that significantly impacts the international community. This includes both major enhancements such as the transition from the VLA to the EVLA in North America, and the development of new facilities such as LOFAR, ALMA, FAST, and Square Kilometre Array precursor telescopes in Australia and South Africa. These developments are driven by advances in radio-frequency, digital and information technologies that tremendously enhance the capabilities in radio astronomy. These new developments foreshadow major scientific advances driven by radio observations in the next triennium. We highlight these facility developments in section 3 of this report. A selection of science highlight from this triennium are summarized in section 2.

Atmospheric turbulence characterization with the Keck adaptive optics systems. I. Open-loop data.

PubMed

Schöck, Matthias; Le Mignant, David; Chanan, Gary A; Wizinowich, Peter L; van Dam, Marcos A

2003-07-01

We present a detailed investigation of different methods of the characterization of atmospheric turbulence with the adaptive optics systems of the W. M. Keck Observatory. The main problems of such a characterization are the separation of instrumental and atmospheric effects and the accurate calibration of the devices involved. Therefore we mostly describe the practical issues of the analysis. We show that two methods, the analysis of differential image motion structure functions and the Zernike decomposition of the wave-front phase, produce values of the atmospheric coherence length r0 that are in excellent agreement with results from long-exposure images. The main error source is the calibration of the wave-front sensor. Values determined for the outer scale L0 are consistent between the methods and with typical L0 values found at other sites, that is, of the order of tens of meters.

Mondim, P.

2016-12-01

The last four years have seen a considerable reduction in the number of candidates for the only Portuguese university degree course in astronomy. As a consequence, a number of measures were taken in order to increase the awareness of astronomy among high school students and to increase the number of students who ultimately decide to apply for the astronomy degree. Here, we present a week-long programme of experimental activities and lectures covering the major fields of astronomy, and an evaluation of its success.

Henrique Azevedo Sobreira, Paulo

2015-08-01

There are some previous works about introductory disciplines of Astronomy in higher education in various undergraduation at Brazilian universities, but this is a specific research for Geography courses in public universities. Some undergraduate courses in Geography in Brazil offer introductory disciplines of Astronomy, since the second half of the twentieth century. This work presents an updated survey on the topic, and it proposes an effort at the national level, for the benefit of the increase in introductory disciplines of Astronomy in undergraduation in Geography. The data collected from public universities were obtained from the consultation of the websites of state universities, federal and county in 2012, 2013 and 2015, for information on the Geography courses and, among them, those with disciplines of Astronomy. The results show that there are 94 undergraduation in Geography courses in public universities, 12 of them had introductory disciplines of Astronomy until 2012 and 2013. In 2015 three of these disciplines were canceled which reduced to 9 universities. There were 23 undergraduation in Geography courses in 10 bachelor degrees and 14 education degrees with Astronomy disciplines. At 2015 it decreased to 20 in 5 bachelors and 8 education degrees. There are two undergraduation Geography courses with two introductory disciplines of Astronomy, while the other 18 offer only one discipline. The inclusion of introductory disciplines of Astronomy depends on the actions of professors' groups who works in undergraduation Geography courses, and of the astronomers initiative to offering them. The ideal is that the astronomers who actuate like professors in universities, normally in Math, Physics, Technologies, Enginnering and Science courses, they would can help and offer introductory disciplines in Astronomy for undergraduation in Geography courses.

The Astronomy Diagnostic Test: Past, Present and Future

NASA Astrophysics Data System (ADS)

Deming, G. L.; Hufnagel, B. R.

2000-12-01

During 1998, the Collaboration for Astronomy Education Research (Adams, Adrian, Brick, Deming, Hufnagel, Slater, and Zeilik) developed a content-based diagnostic test for undergraduate non-science majors taking their first introductory level astronomy course. Student interviews and written feedback were used to construct a series of questions reflecting the students' natural language and with distractors (wrong answers) that mirror commonly held misconceptions. Version 1.9 of the Astronomy Diagnostic Test (ADT) was administered during Spring 1999 by volunteers teaching astronomy at 22 institutions across the United States. Minor modifications were made and Version 2.0 was released on June 21, 1999. The ADT 2.0 currently is available to the astronomical community through two websites and we continue to collect pretest/posttest results. Award of an NSF Small Grant for Exploratory Research has enabled us to work with a team of education researchers at the Ontario Institute for Studies in Education. Our database will be subjected to a statistical analysis in order to establish reliability of ADT 2.0. In addition, content, face, and construct validity are being examined. If you are teaching an introductory astronomy course aimed at non-science majors for Spring 2001, your class can be part of this project. We are looking for volunteers! We are also interested in hearing your ideas for a "next-generation" version of the ADT. Funding provided by NSF grant REC-0089239

Energy, The Environment And Astronomy: Education And Action

2010-01-01

The specter of global climate change is arguably the most pressing scientific, social and ethical issue of our time. Although the relatively small field of astronomy represents only a fraction of the total human carbon emissions, astronomers have a great potential, and therefore perhaps a great responsibility, to educate themselves and the public on this issue. In addition, the average per capita carbon emissions of professional astronomers are not small, and our profession can do much to reduce its energy consumption and maximize the cost-benefit ratio of our work. At the January AAS meeting, we are organizing a half-day splinter meeting titled "Energy, the Environment and Astronomy: Education and Action". The focus will be on energy conservation and education as it relates to professional astronomy. Education focuses on informing ourselves, our students and the general public with which we interact, about the real issues, the necessary actions, and the likely consequences of various energy consumption and carbon emission scenarios. Action focuses on effective energy conservation and renewable energy initiatives within professional astronomy. Air travel, solar energy at ground-based observatories, and Gemini's "Green Initiative” are among the topics that will be discussed. The splinter meeting will be open to all and will include expert speakers from outside astronomy, contributed talks by astronomers, and a discussion session.

Modern astronomy is a crowning achievement of human civilization which inspires teenagers to choose career in science and technology and is a stable of adult education. It is a unique and cost effective tool for furthering sustainable global development because of its technological, scientific and cultural dimensions which allow us to reach with the large portion of the community interact with children and inspire with our wonderful cosmos.Using astronomy to stimulate quality and inspiring education for disadvantaged children is an important goal of Nepal Astronomical Society (NASO) since its inception. NASO is carrying out various awareness activities on its own and in collaboration with national and international organizations like Central Department of Physics Tribhuvan University (TU), International astronomical Union (IAU), Department of Physics Prithvi Narayan Campus Pokhara, Nepal academy of science and technology (NAST), Global Hands on Universe (GHOU), EU- UNAWE and Pokhara Astronomical Society (PAS) to disseminate those activities for the school children and teachers in Nepal. Our experiences working with kids, students, teachers and public in the field of universe Awareness Activities for the school children to minimize the abstruse concept of astronomy through some practical approach and the project like Astronomy for the visually impaired students, Galileo Teacher Training program and International School for young astronomers (ISYA) outskirts will be explained which is believed to play vital role in promoting astronomy and space science activities in Nepal.

On March 2015 an L'-band vortex coronagraph based on an Annular Groove Phase Mask made up of a diamond sub-wavelength grating was installed on NIRC2 as a demonstration project. This vortex coronagraph operates in the L' band not only in order to take advantage from the favorable star/planet contrast ratio when observing beyond the K band, but also to exploit the fact that the Keck II Adaptive Optics (AO) system delivers nearly extreme adaptive optics image quality (Strehl ratios values near 90%) at 3.7μm. We describe the hardware installation of the vortex phase mask during a routine NIRC2 service mission. The success of the project depends on extensive software development which has allowed the achievement of exquisite real-time pointing control as well as further contrast improvements by using speckle nulling to mitigate the effect of static speckles. First light of the new coronagraphic mode was on June 2015 with already very good initial results. Subsequent commissioning nights were interlaced with science nights by members of the VORTEX team with their respective scientific programs. The new capability and excellent results so far have motivated the VORTEX team and the Keck Science Steering Committee (KSSC) to offer the new mode in shared risk mode for 2016B.

Explorers of the Southern Sky: A History of Australian Astronomy

NASA Astrophysics Data System (ADS)

Haynes, Raymond; Haynes, Roslynn D.; Malin, David; McGee, Richard

1996-06-01

This well-illustrated volume is the most comprehensive account of Australian astronomy to date. It is both an indispensable reference book on the history of astronomy in Australia, and a highly readable study of a scientific discipline in the context of emerging nationhood. It covers not only the science, but the individuals involved and the social and economic climate in which they worked. Starting from the ancient Aboriginal beliefs about the Sky World - the earliest known astronomy, anywhere in the world - we are led through to the most exciting high-tech current and projected research being carried out at Australia's world-class national astronomy facilities, and by groups in Australian universities. All branches of astronomy are covered - optical, infrared, X-ray, gamma-ray, microwave, gravitational wave and theoretical - including the contribution of amateur astronomers. The non-technical language, many illustrations, and explanatory figures, ensure that this guide will appeal to a wide range of readers - including professional astronomers, historians of science, students, amateur astronomers and general readers.

The New Curriculum Standards for Astronomy in the United States

Schleigh, Sharon P.; Slater, Stephanie J.; Slater, Timothy F.; Stork, Debra J.

2015-12-01

There is widespread interest in constraining the wide range and vast domain of the possible topics one might teach about astronomy into a manageable framework. Although there is no mandated national curriculum in the United States, an analysis of the three recent national efforts to create an age-appropriate sequence of astronomy concepts to be taught in primary and secondary schools reveals a considerable lack of consensus of which concepts are most age-appropriate and which topics should be covered. The most recent standardization framework for US science education, the Next Generation Science Standards, suggests that most astronomy concepts should be taught only in the last years of one’s education; however, the framework has been met with considerable criticism. A comparison of astronomy learning frameworks in the United States, and a brief discussion of their criticisms, might provide international astronomy educators with comparison data in formulating recommendations in their own regions.

Stern, S. Alan

1998-01-01

This 1-year project was an augmentation grant to my NASA Planetary Astronomy grant. With the awarded funding, we accomplished the following tasks: (1) Conducted two NVK imaging runs in conjunction with the ILAW (International Lunar Atmosphere Week) Observing Campaigns in 1995 and 1997. In the first run, we obtained repeated imaging sequences of lunar Na D-line emission to better quantify the temporal variations detected in earlier runs. In the second run we obtained extremely high resolution (R=960.000) Na line profiles using the 4m AAT in Australia. These data are being analyzed under our new 3-year Planetary Astronomy grant. (2) Reduced, analyzed, and published our March 1995 spectroscopic dataset to detect (or set stringent upper limits on) Rb. Cs, Mg. Al. Fe, Ba, Ba. OH, and several other species. These results were reported in a talk at the LPSC and in two papers: (1) A Spectroscopic Survey of Metallic Abundances in the Lunar Atmosphere. and (2) A Search for Magnesium in the Lunar Atmosphere. Both reprints are attached. Wrote up an extensive, invited Reviews of Geophysics review article on advances in the study of the lunar atmosphere. This 70-page article, which is expected to appear in print in 1999, is also attached.

Special Session 4: Astronomy Education between Past and Future

NASA Astrophysics Data System (ADS)

de Greve, Jean-Pierre

2010-11-01

The special session aims at discussing an integrated approach of the different efforts to increase and promote the teaching and learning of astronomy in the world, with emphasis on developing countries. To this end, attention will be given to research on education, specifically in the field of physics, to best practices of the use of astronomy in educational systems (specifically in developing countries), and to innovative learning initiatives other than formal education. The Special Session aims also at creating a universal perspective wherein modern (post-Copernican) astronomy will presented as an intellectual cumulus. The objective of the session is to disseminate best practices in teaching and learning activities of astronomy and to give an opportunity to learn about initiatives in different cultural and socio-economic settings. The special session also wants to give food-for-thought and proposals for reflection for an integrative approach, and for optimization processes, to enhance the interest in astronomy and its role as a trigger towards science education in the educational systems, with emphasis on the developing countries. The outcome should be a sensitization of teachers and students alike to the concept of a universal history of astronomy and creation of some reliable source material which can be used as a teaching aid in a culture-specific context. The outcome could be a set of recommendations for future integrated actions, and eventually recommendations on new initiatives, framed into the new decadal policy plan.

Astronomy Education and Popularization Facilities at Guanajuato University in Mexico

NASA Astrophysics Data System (ADS)

Bravo-Alfaro, H.; Schroeder, K.-P.; Ramirez, L.

2006-08-01

At the Astronomy Department of Universidad de Guanajuato, 400 km NW of Mexico City, nine professional astronomers do research and teaching at both graduate and undergraduate level. In addition, in the last few years, this group has carried out astronomy popularization activities at three different sites. First, a rudimentary observatory named "La Azotea" (the roof) on the top of the main building of the University (at Guanajuato centre), which includes a 16-cm refractor in a dome, a couple of XIXth century astronomical instruments, and a classroom with capacity for 50 people. The refractor was out of use for about twelve years but will be fully operational before summer 2006. Second, the "Observatorio de La Luz", 20 kms away from Guanajuato centre, includes a professional 0.6m Cassegrain and a 2m radio telescope, with a 21cm receiver. Finally, on the roof of the Astronomy Department headquarters, an optical 0.4m Dobsonian is available. We also dispose of internet connection everywhere and 6 portable 8-inch telescopes (two at each site), devoted to regular astronomical observations for the general public, specially for scholars. Numerous repair works are currently carried out on the building of "La Azotea", and recently a project to establish there a Centre for Popularization of Astronomy has been approved by the Regional Science Council. The main activities, some of them currently developed at these sites are: (1) A permanent program of astronomical observations for a wide audience. (2) Training in Observational Astronomy for physics undergraduate students. (3) Regular talks on astronomy and other science domains. (4) Summer schools in Astronomy for elementary and high-school teachers. (5) In the near future, the foundation of an amateur society of astronomy.

``Astrophysique sur Mesure'', E-learning in Astronomy and Astrophysics

NASA Astrophysics Data System (ADS)

Mosser, Benoît; Delsanti, Audrey; Guillaume, Damien; Balança, Christian; Balkowski, Chantal

2011-06-01

``Astrophysique sur Mesure'' (astrophysics made-to-measure) is a set of e-learning programmes started 4 years ago at the Paris Observatory. In order to deliver attractive and efficient programmes, we have added many multimedia tools to usual lectures: animations, Java applets. The programmes are presented on two different platforms. The first one offers the content of all the lectures in free access. A second platform with restricted access is provided to registered students taking part in the e-learning program and benefiting from the help of tutors. The development of these programs helps to increase the sphere of influence of astronomy taught at the Paris Observatory, hence to increase the presence of astronomy in various degree courses. Instead of teaching classical astronomy lectures to a happy few, we can bring astronomy and astrophysics to a wider audience.

SABER: The Searchable Annotated Bibliography of Education Research in Astronomy

NASA Astrophysics Data System (ADS)

Bruning, David H.; Bailey, J. M.; Brissenden, G.

2006-12-01

Starting a new research project in astronomy education is hard because the literature is scattered throughout many journals. Relevant astronomy education research may be in psychology journals, science education journals, physics education journals, or even in science journals themselves. Tracking the vast realm of literature is difficult, especially since libraries do not carry many of these journals and related abstracting services. SABER is an online resource (http://astronomy.uwp.edu/saber/) that was started in 2001 specifically to reduce this “scatter” by compiling into one place an annotated bibliography of relevant education research articles. The database now includes more than 150 articles specifically addressing astronomy education research. Visit SABER and see what it can do for you.

The Development of Astronomy and Emergence of Astrophysics in New Zealand

NASA Astrophysics Data System (ADS)

Hearnshaw, John; Orchiston, Wayne

The development of astronomy and astrophysics in New Zealand from the earliest European exploration and settlement to the present day is discussed. The major contributions to astronomy by amateur astronomers are covered, as is the later development of astronomy and astrophysics in New Zealand's universities. The account includes the founding of professional observatories for optical astronomy at Mt. John (belonging to the University of Canterbury) and for radio astronomy at Warkworth (belonging to the Auckland University of Technology). Several major international collaborations in which New Zealand is participating (or has participated) are described, including SALT, MOA, IceCube and SKA. The founding and history of the Carter Observatory in Wellington, of the Stardome Observatory in Auckland (both engaged in astronomical education and outreach) and of the Royal Astronomical Society of New Zealand are briefly covered.

ASTRONET: Strategic Planning for European Astronomy 2005-2025

NASA Astrophysics Data System (ADS)

Andersen, Johannes; Mourard, Denis

2015-08-01

European astronomy, with ESO and ESA, is supported by a wide variety of independent national agencies or similar bodies, which jointly provide ~98% of the total funding (with ~2% EU grants). In 2005 these agencies concluded that common strategic planning would be a more cost-effective approach, so they founded a consortium, ASTRONET (http://www.astronet-eu.org/), to prototype such an effort for all of Europe, with EU support. A bottom-up process resulted in a Science Vision (2007) and Infrastructure Roadmap (2008) for European astronomy, with recent updates (2014).These ASTRONET reports cover all branches of astronomy; infrastructures at all electromagnetic wavelengths as well as particles etc., on the ground and in space; laboratory work, software and archiving; and training, recruitment and public outreach. In short, they are agreed blueprints for what Europe plans to accomplish in the next 1-2 decades.Subsequently, a systematic and sustained pragmatic effort has been made to implement the strategy laid out in the Roadmap, including a common European participation in projects and facilities of global dimensions. Decisions on the organisation and construction of several major research facilities have been taken as foreseen (E-ELT, SKA, CTA,…), and they are on track for completion around 2025. The task for global astronomy is now to optimise the overall scientific returns and cost-effectiveness of these investments across wavelength domains, scientific disciplines, and political and financial borders. Accordingly, ASTRONET is currently transforming itself into a permanent, self-sustaining activity reaching out to the world.The ideal of a fully integrated global astronomy may not be reached until ~2050, but no science is better suited than astronomy to set such an example: One Universe surrounds us all, and one Earth is our platform. The IAU General Assembly is a springboard towards this goal.

Introducing Astronomy Allies: We are here to help!

Flewelling, Heather; Alatalo, Katherine A.

Imagine you are a grad student, at your first conference, and a prominent senior scientist shows interest in your work, and he makes things get way too personal? What would you do? Would you report it? Or would you decide, after a few other instances of harassment, that maybe you shouldn't pursue astronomy? Harassment is under-reported, the policies can be difficult to understand or hard to find, and it can be very intimidating as a young scientist to report it to the proper individuals. The Astronomy Allies Program is designed to help you with these sorts of problems. We are a group of volunteers that will help by doing the following: provide safe walks home during the conference, someone to talk to confidentially, as an intervener, as a resource to report harassment. The Allies are a diverse group of scientists committed to acting as mentors, advocates, and liaisons. The Winter 2015 AAS meeting will be the first meeting that has Astronomy Allies, and Astronomy Allies will provide a website for information, as well as a twitter, email, and phone number for anyone who needs our help or would like more information. We posted about the Astronomy Allies on the Women In Astronomy blog, and this program resonates with many people: either they want to help, or they have experienced harassment in the past and don't want to see it in the future. Harassment may not happen to most conference participants, but it's wrong, it's against the AAS anti-harassment policy ( http://aas.org/policies/anti-harassment-policy ), it can be very damaging, and if it happens to even one person, that is unacceptable. We intend to improve the culture at conferences to make it so that harassers feel they can't get away with their unprofessional behavior.

New Candidate Supernova Remnants in the Small Magellanic Cloud

NASA Astrophysics Data System (ADS)

Winkler, P. F.; Lewinter, R.

1992-12-01

We have surveyed six 30(') times 30(') fields in the Small Magellanic Cloud, using the Curtis Schmidt telescope at CTIO with a Thomson CCD, to search for previously undetected supernova remnants (SNRs). Narrow-band images are obtained in lines of [S II] (lambda lambda \\ 6716,31), Hα , and a nearby continuum band. The ratio of [S II]/Hα \\ emission discriminates well between shock-heated material charcteristic of SNRs and photo-ionized material such as H II regions. This technique has proved highly effective in surveys of other galaxies (e.g. Long et al., Ap J Supp, 72, 61). Deep emission-line images and a continuum band closely matched in wavelength enable us to subtract virtually the entire stellar contribution and thus achieve high sensitivity to faint, diffuse emission. We have identified 13 objects, all of which have [S II]/Hα \\ ratios > 0.4\\ and a full or partial shell-like morphology, making them extremely strong SNR candidates. Several other diffuse objects have high [S II]/Hα \\ ratios, and many of these may also be SNRs. Compared with the 12 previously known remnants of Mathewson et al., (Ap J Supp 51, 345; 55, 189), the new candidates are generally larger and have lower surface brightness. An investigation of the cumulative number vs diameter relation for our larger sample indicates a slope significantly steeper than the value near unity originally found by Mathewson et al., and is more consistent with standard models for SNR evolution. Selection effects may well have led to an excess of small, bright objects in the earlier samples. This work was supported in part by NSF grant AST-9114935 and by the W.M. Keck Foundation through the Keck Northeast Astronomy Consortium.
