Most theoretical work on coded aperture masks in X-ray and low-energy gamma-ray astronomy has concentrated on masks with large numbers of elements. For gamma-ray spectrometers in the MeV range, the detector plane usually has only a few discrete elements, so that masks with small numbers of elements are called for. For this case it is feasible to analyze by computer all the possible mask patterns of given dimension to find the ones that best satisfy the desired performance criteria. A particular set of performance criteria for comparing the flux sensitivities, source positioning accuracies and transparencies of different mask patterns is developed. The results of such a computer analysis for masks up to dimension 5 x 5 unit cell are presented and it is concluded that there is a great deal of flexibility in the choice of mask pattern for each dimension.

Cosmic gamma rays, the physical processes responsible for their production and the astrophysical sites from which they were seen are reported. The bulk of the observed gamma ray emission is in the photon energy range from about 0.1 MeV to 1 GeV, where observations are carried out above the atmosphere. There are also, however, gamma ray observations at higher energies obtained by detecting the Cerenkov light produced by the high energy photons in the atmosphere. Gamma ray emission was observed from sources as close as the Sun and the Moon and as distant as the quasar 3C273, as well as from various other galactic and extragalactic sites. The radiation processes also range from the well understood, e.g. energetic particle interactions with matter, to the still incompletely researched, such as radiation transfer in optically thick electron positron plasmas in intense neutron star magnetic fields.

H.E.S.S. and CTA, present and perspectives in ground-based gamma-ray astronomy

Very high energy (VHE) gamma-ray astronomy emerged as a new branch of astronomy about ten years ago with the major discoveries achieved by the High Energy Stereocopic System (H.E.S.S.) operating in Namibia, quickly followed by the Major Atmospheric Gamma Imaging Cherenkov Telescopes (MAGIC) in the Canary Islands and the Very Energetic Radiation Imaging Telescope Array System (VERITAS) in the USA. These experiments succeeded to start exploring the cosmos at TeV energies, with the present detection of 178 sources in this range, mostly pulsar wind nebulae, supernova remnants, binary systems, blazars, and a variety of other types of sources. Based on these promizing results, the scientific community soon defined a next generation global project with significantly improved performance, the Cherenkov Telescope Array (CTA), in order to implement an open observatory at extreme energies, allowing a deep analysis of the sky in the highest part of the electromagnetic spectrum, from 20 GeV to 300 TeV. The CTA preparation phase is now completed. Production of the first telescopes should start in 2017 for deployment in 2018, in the perspective of an array fully operational at the horizon 2022.

Observations of gamma rays from solar flares, gamma ray bursts, the Galactic center, galactic nucleosynthesis, SS433, and Cygnus X-3, and their effects on astrophysical problems are discussed. It is observed that gamma ray spectra from solar flares are applicable to the study of particle acceleration and confinement and the determination of chemical abundances in the solar atmosphere. The gamma ray lines from the compact galactic object SS433 are utilized to examine the acceleration of jets, and analysis of the gamma ray lines of Cygnus X-3 reveal that particles can be accelerated in compact sources to ultrahigh energies.

1988-01-01

Important developments in gamma-ray astrophysics up to energies of 100 GeV during the last decade are reviewed. Also, the report seeks to define the major current scientific goals of the field and proposes a vigorous program to pursue them, extending to the year 2000. The goals of gamma-ray astronomy include the study of gamma rays which provide the most direct means of studying many important problems in high energy astrophysics including explosive nucleosynthesis, accelerated particle interactions and sources, and high-energy processes around compact objects. The current research program in gamma-ray astronomy in the U.S. including the space program, balloon program and foreign programs in gamma-ray astronomy is described. The high priority recommendations for future study include an Explorer-class high resolution gamma-ray spectroscopy mission and a Get Away Special cannister (GAS-can) or Scout class multiwavelength experiment for the study of gamma-ray bursts. Continuing programs include an extended Gamma Ray Observatory mission, continuation of the vigorous program of balloon observations of the nearby Supernova 1987A, augmentation of the balloon program to provide for new instruments and rapid scientific results, and continuation of support for theoretical research. Long term recommendations include new space missions using advanced detectors to better study gamma-ray sources, the development of these detectors, continued study for the assembly of large detectors in space, collaboration with the gamma-ray astronomy missions initiated by other countries, and consideration of the Space Station attached payloads for gamma-ray experiments.

The Advanced Gamma-ray Imaging System (AGIS) is a next-generation array of imaging atmospheric Cherenkov telescopes for gamma-ray astronomy in the 100 GeV to 100 TeV band. TeV astronomy has flourished in the last few years. Together with the extremely successful first year of the Fermi LAT telescope for GeV gamma-ray astronomy, we are now in a golden age of gamma-ray astronomy. AGIS seeks to continue the success of gamma-ray astronomy by discovering hundreds of new TeV sources and improving our understanding of known sources, as well as searching for signals from dark matter annihilation. AGIS will feature 36 Schwarzschild-Couder (SC) telescopes spanning 1 km2. The two-mirror SC design allows a wide field of view (8 deg diameter) and high-resolution (0.05 deg diameter) pixellation. I will present the science capabilities of the AGIS observatory as well as the technical design and current status of the project.

A fast scintillator Compton telescope for medium-energy gamma-ray astronomy

The field of medium-energy gamma-ray astronomy urgently needs a new mission to build on the success of the COMPTEL instrument on the Compton Gamma Ray Observatory. This mission must achieve sensitivity significantly greater than that of COMPTEL in order to advance the science of relativistic particle accelerators, nuclear astrophysics, and diffuse backgrounds, and bridge the gap between current and future hard X-ray missions and the high-energy Fermi mission. Such an increase in sensitivity can only come about via a dramatic decrease in the instrumental background. We are currently developing a concept for a low-background Compton telescope that employs modern scintillator technology to achieve this increase in sensitivity. Specifically, by employing LaBr3 scintillators for the calorimeter, one can take advantage of the unique speed and resolving power of this material to improve the instrument sensitivity while simultaneously enhancing its spectroscopic and imaging performance. Also, using deuterated organic scintillator in the scattering detector will reduce internal background from neutron capture. We present calibration results from a laboratory prototype of such an instrument, including time-of-flight, energy, and angular resolution, and compare them to simulation results using a detailed Monte Carlo model. We also describe the balloon payload we have built for a test flight of the instrument in the fall of 2010.

The technical activities, scientific results, related space hardware projects and personnel of the high energy astrophysics program are reported. The development of observational and instrumental techniques in hard X-ray (0.001 to 100 keV) and medium energy gamma-ray (0.1 to 10 MeV) astronomy are examined. Many of these techniques were developed explicitly for use on high altitude balloons where most of the scientific results were obtained. The extensive observational activity using balloons are tabulated. Virtually every research activity will eventually result in a major space hardware development effort.

Very high-energy (VHE) gamma-ray astronomy has undergone a transformation in the last few years, with telescopes of unprecedented sensitivity having greatly expanded the source catalogue. Such progress makes the detection of a gamma-ray burst at the highest energies much more likely than previously. This paper describes the facilities currently operating and their chances for detecting gamma-ray bursts, and reviews predictions for VHE gamma-ray emission from gamma-ray bursts. Results to date are summarized.

Because high-energy gamma rays are primarily produced by high-energy particle interactions, the gamma-ray survey of the sky by the Fermi Gamma-ray Space Telescope offers a view of sites of cosmic ray production and interactions. Gamma-ray bursts, pulsars, pulsar wind nebulae, binary sources, and Active Galactic Nuclei are all phenomena that reveal particle acceleration through their gamma-ray emission. Diffuse Galactic gamma radiation, Solar System gamma-ray sources, and energetic radiation from supernova remnants are likely tracers of high-energy particle interactions with matter and photon fields. This paper will present a broad overview of the constantly changing sky seen with the Large Area Telescope (LAT) on the Fermi spacecraft.

2008-01-01

The launch of the Gamma-ray Large Area Space Telescope together with the advent of a new generation of ground-based gamma-ray detectors such as VERITAS, HESS, MAGIC and CANGAROO, will usher in a new era of high-energy gamma-ray astrophysics. GLAST and the ground based gamma-ray observatories will provide highly complementary capabilities for spectral, temporal and spatial studies of high energy gamma-ray sources. Joint observations will cover a huge energy range, from 20 MeV to over 20 TeV. The LAT will survey the entire sky every three hours, allowing it both to perform uniform, long-term monitoring of variable sources and to detect flaring sources promptly. Both functions complement the high-sensitivity pointed observations provided by ground-based detectors. Finally, the large field of view of GLAST will allow a study of gamma-ray emission on large angular scales and identify interesting regions of the sky for deeper studies at higher energies. In this poster, we will discuss the science returns that might result from joint GLAST/ground-based gamma-ray observations and illustrate them with detailed source simulations.

This Atlas/Centaur launch vehicle, carrying the High Energy Astronomy Observatory (HEAO)-3, lifted off on September 20, 1979. The HEAO-3's mission was to survey and map the celestial sphere for gamma-ray flux and make detailed measurements of cosmic-ray particles. It carried three scientific experiments: a gamma-ray spectrometer, a cosmic-ray isotope experiment, and a heavy cosmic-ray nuclei experiment. The HEAO-3 was originally identified as HEAO-C but the designation was changed once the spacecraft achieved orbit.

Gamma ray astronomy and black hole astrophysics

Liang, Edison P.

1990-01-01

The study of soft gamma emissions from black-hole candidates is identified as an important element in understanding black-hole phenomena ranging from stellar-mass black holes to AGNs. The spectra of Cyg X-1 and observations of the Galactic Center are emphasized, since thermal origins and MeV gamma-ray bumps are evident and suggest a thermal-pair cloud picture. MeV gamma-ray observations are suggested for studying black hole astrophysics such as the theorized escaping pair wind, the anticorrelation between the MeV gamma bump and the soft continuum, and the relationship between source compactness and temperature.

Air shower detectors in gamma-ray astronomy

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

Sinnis, Gus

2008-01-01

Extensive air shower (EAS) arrays directly detect the particles in an EAS that reach the observation altitude. This detection technique effectively makes air shower arrays synoptic telescopes -- they are capable of simultaneously and continuously viewing the entire overhead sky. Typical air shower detectors have an effective field-of-view of 2 sr and operate nearly 100% of the time. These two characteristics make them ideal instruments for studying the highest energy gamma rays, extended sources and transient phenomena. Until recently air shower arrays have had insufficient sensitivity to detect gamma-ray sources. Over the past decade, the situation has changed markedly. Milagro,more » in the US, and the Tibet AS{gamma} array in Tibet, have detected very-high-energy gamma-ray emission from the Crab Nebula and the active galaxy Markarian 421 (both previously known sources). Milagro has discovered TeV diffuse emission from the Milky Way, three unidentified sources of TeV gamma rays, and several candidate sources of TeV gamma rays. Given these successes and the suite of existing and planned instruments in the GeV and TeV regime (AGILE, GLAST, HESS, VERITAS, CTA, AGIS and IceCube) there are strong reasons for pursuing a next generation of EAS detectors. In conjunction with these other instruments the next generation of EAS instruments could answer long-standing problems in astrophysics.« less

Innovative Research Program: Supershields for Gamma-Ray Astronomy

NASA Technical Reports Server (NTRS)

Hailey, Charles J.

2000-01-01

The supershield project evaluated the importance of novel shield configurations for suppressing neutron induced background in new classes of gamma-ray detectors such as CZT. The basic concept was to use a two-part shield. The outer shield material heavily moderates the incoming neutron spectrum. This moderated neutron beam is then more easily absorbed by the inner material, which is an efficient neutron absorber. This approach is, in principle, more efficient than that in previous attempts to make neutron shields. These previous attempts involved biatomic, monlithic shields (eg. LiH) in which the shield consisted of a single material but with two types of atoms - one for moderating and one for absorbing. The problem with this type of monolithic shield is that moderating neutrons, without the efficient absorption of them, leads to the leakage into the detector of neutrons with a low energy component (approx. 10-100 KeV). These energy neutrons are particularly problematic for many types of detectors. The project was roughly divided into phases. In the first phase we attempted to carefully define the neutron source function incident on any space instrument. This is essential since the design of any shield depends on the shape of the incident neutron spectrum. We found that approximations commonly used in gamma-ray astronomy for photon background is inadequate. In addition, we found that secondary neutrons produced in any passive shield, and dominated by inelastic neutron scattering, are far more important than background due to neutron activation. The second phase of our work involved design of supershield geometries (one and three dimensional) in order to compare different shield configurations and materials for their effectiveness as neutron shields. Moreover we wanted to compare these supershields with previous neutron shields to confirm the performance differences between the supershield (two material) and monolithic (one material) designs and to understand the

Hui, C. M.

2017-01-01

The Fermi Gamma-ray Burst Monitor (GBM) is an all-sky monitoring instrument sensitive to energies from 8 kiloelectronvolts to 40 megaelectronvolts. Over the past 8 years of operation, the GBM has detected over 240 gamma-ray bursts per year and provided timely GCN (Gamma-ray Coordinates Network) notices with localization to few-degree accuracy for follow-up observations. In addition to GRBs, galactic transients, solar flares, and terrestrial gamma-ray flashes have also been observed. In recent years we have also been searching the continuous GBM data for electromagnetic counterpart to astrophysical neutrinos and gravitational wave events, as these are believed to be associated with gamma-ray bursts. With continuous data downlink every few hours and a temporal resolution of 2 microseconds, GBM is well suited for observing transients and supporting EM followup in the era of multi-messenger astronomy.

Explorers of the Southern Sky: A History of Australian Astronomy

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.

Overview of lunar-based astronomy

NASA Technical Reports Server (NTRS)

Smith, Harlan J.

1988-01-01

The opportunities along with the advantages and disadvantages of the Moon for astronomical observatories are carefully and methodically considered. Taking a relatively unbiased approach, it was concluded that lunar observatories will clearly be a major factor in the future of astronomy in the next century. He concludes that ground based work will continue because of its accessibility and that Earth orbital work will remain useful, primarily for convenience of access in constructing and operating very large space systems. Deep space studies will feature not only probes but extensive systems for extremely long baseline studies at wavelengths from gamma rays through visible and IR out to radio is also a conclusion drawn, along with the consideration that lunar astronomy will have found important permanent applications along lines such as are discussed at the present symposium and others quite unsuspected today.

The field of gamma-ray astronomy has seen important progress during the last decade, yet to date no common software framework has been developed for the scientific analysis of gamma-ray telescope data. We propose to fill this gap by means of the GammaLib software, a generic library that we have developed to support the analysis of gamma-ray event data. GammaLib was written in C++ and all functionality is available in Python through an extension module. Based on this framework we have developed the ctools software package, a suite of software tools that enables flexible workflows to be built for the analysis of Imaging Air Cherenkov Telescope event data. The ctools are inspired by science analysis software available for existing high-energy astronomy instruments, and they follow the modular ftools model developed by the High Energy Astrophysics Science Archive Research Center. The ctools were written in Python and C++, and can be either used from the command line via shell scripts or directly from Python. In this paper we present the GammaLib and ctools software versions 1.0 that were released at the end of 2015. GammaLib and ctools are ready for the science analysis of Imaging Air Cherenkov Telescope event data, and also support the analysis of Fermi-LAT data and the exploitation of the COMPTEL legacy data archive. We propose using ctools as the science tools software for the Cherenkov Telescope Array Observatory.

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

Rossi and high-energy astronomy

NASA Astrophysics Data System (ADS)

Clark, George W.

2012-03-01

The contributions of Bruno Rossi to high-energy astronomy began in Italy in the 1930s with investigations concerning the nature of cosmic rays in theory and in hands-on experiments at the universities of Florence and Padua. Recent discoveries had cast doubt on Robert Millikan's idea that the primary cosmic rays are gamma rays created in the production of the elements by fusion of hydrogen atoms in interstellar space. Rossi entered the field with a prediction published in 1930 of a difference between the intensity of cosmic rays from the east and the west that would occur if the primary cosmic rays were charged particles of one sign. In the same year he invented the first practical electronic coincidence circuit, which he used in a series of fundamental particle experiments and in an unsuccessful attempt to detect an east-west effect at Florence. Expecting by theory that the effect would be greater at high altitude near the equator, he took his experiment to Eritrea in 1934 where his measurements demonstrated that the primary cosmic rays are predominantly positive particles. In the report of his expedition he also described his discovery of extensive cosmic-ray air showers. After WWII and his work at Los Alamos, Rossi resumed his cosmic-ray research, now at MIT, in a new style best described in his own words: ``Now I had the responsibility of an entire group, and what mattered was no longer my own work, but the work of the group.'' He suggested the new methods of ``density sampling'' and ``fast timing'' for air shower studies, and promoted their application in numerous experiments on the nature and origins of the highest energy cosmic rays. In 1959 he initiated and participated as a consultant in the work of Riccardo Giacconi that led to the discovery of the first x-ray star, Sco X-1, and the development of the first imaging x-ray telescopes. At MIT, members of the Rossi Cosmic Ray Group took the early steps in gamma-ray astronomy, first with balloon experiments

Gamma-Ray Bursts: An Overview

NASA Technical Reports Server (NTRS)

Fishman, Gerald J.

1995-01-01

A history and overview of the observed properties of gamma-ray bursts are presented. The phenomenon of gamma-ray bursts is without precedent in astronomy, having no observed property that would be a direct indicator of their distance and no counterpart object in another wavelength region. Their brief, random appearance only in the gamma-ray region has made their study difficult. The observed time profiles, spectral properties, and durations of gamma-ray bursts cover a wide range. All proposed models for their origin must be considered speculative. It is humbling to think that even after 25 years since their discovery, the distance scale of gamma-ray bursts is still very much debatable.

Trombka, J. I.; Fichtel, C. E.; Grindlay, J.; Hofstadter, R.

1978-01-01

Gamma-ray astronomy which includes the spectral region from above approximately 100 keV to greater than or equal to 1000 GeV permits investigation of the most energetic photons originating in our galaxy and beyond and provides the most direct means of studying the largest transfers of energy occurring in astrophysical processes. Of all the electromagnetic spectrum, high-energy gamma-ray astronomy measures most directly the presence and dynamic effects of the energetic charged cosmic ray particles, element synthesis, and particle acceleration. Further, gamma rays suffer negligible absorption or scatterings as they travel in straight paths; hence, they may survive billions of years and still reveal their source. The high energy processes in stellar objects (including our Sun), the dynamics of the cosmic-ray gas, the formation of clouds and nebulae, galactic evolution and even certain aspects of cosmology and the origin of the universe may be explored by gamma-ray observations.

Astronomy in the City for Astronomy Education

NASA Astrophysics Data System (ADS)

Ros, Rosa M.; Garc, Beatriz

2016-10-01

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.

The forthcoming NASA project of orbiting High Energy Astronomy Observatories (HEAO's) designed to probe the universe by tracing celestial radiations and particles is outlined. Solutions to engineering problems concerning HEAO's which are integrated, yet built to function independently are discussed, including the onboard digital processor, mirror assembly and the thermal shield. The principle of maximal efficiency with minimal cost and the potential capability of the project to provide explanations to black holes, pulsars and gamma-ray bursts are also stressed. The first satellite is scheduled for launch in April 1977.

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).

Lunar occultations for gamma-ray source measurements

Koch, David G.; Hughes, E. B.; Nolan, Patrick L.

1990-01-01

The unambiguous association of discrete gamma-ray sources with objects radiating at other wavelengths, the separation of discrete sources from the extended emission within the Galaxy, the mapping of gamma-ray emission from nearby galaxies and the measurement of structure within a discrete source cannot presently be accomplished at gamma-ray energies. In the past, the detection processes used in high-energy gamma-ray astronomy have not allowed for good angular resolution. This problem can be overcome by placing gamma-ray detectors on the moon and using the horizon as an occulting edge to achieve arcsec resolution. For purposes of discussion, this concept is examined for gamma rays above 100 MeV for which pair production dominates the detection process and locally-generated nuclear gamma rays do not contribute to the background.

On the e-process - Its components and their neutron excesses. [solar abundance calculations in gamma ray astronomy

Hainebach, K. L.; Clayton, D. D.; Arnett, W. D.; Woosley, S. E.

1974-01-01

The pattern of abundances within the iron-abundance peak of the solar system is analyzed for various Cr, Fe, and Ni abundances, and a method is developed for finding the best fit to a given set of abundances with a chosen number of zones, i.e., mass contributions characterized by differing values of eta. This material can be synthesized by a superposition of e-process compositions in a low-eta region (eta = 0.003) and a high-eta region (eta = 0.065 -0.080) with at least 85% coming from the low-eta region. Addition of a third eta zone is unproductive. The applicability of the particle-poor freeze out is discussed in the light of these abundances, and the results of employing different numbers and types of zones are interpreted as an indication of the relative abundances themselves. Ejection of the low-eta zones is of great interest in gamma-ray astronomy and for empirical testing of theories of nucleosynthesis. The distribution of high zones should give important information about the formation of collapsed remnants.

Whilst astronomy as a science is historically founded on observations at optical wavelengths, studying the Universe in other bands has yielded remarkable discoveries, from pulsars in the radio, signatures of the Big Bang at submm wavelengths, through to high energy emission from accreting, gravitationally-compact objects and the discovery of gamma-ray bursts. Unsurprisingly, the result of combining multiple wavebands leads to an enormous increase in diagnostic power, but powerful insights can be lost when the sources studied vary on timescales shorter than the temporal separation between observations in different bands. In July 2015, the workshop ;Paving the way to simultaneous multi-wavelength astronomy; was held as a concerted effort to address this at the Lorentz Center, Leiden. It was attended by 50 astronomers from diverse fields as well as the directors and staff of observatories and spaced-based missions. This community white paper has been written with the goal of disseminating the findings of that workshop by providing a concise review of the field of multi-wavelength astronomy covering a wide range of important source classes, the problems associated with their study and the solutions we believe need to be implemented for the future of observational astronomy. We hope that this paper will both stimulate further discussion and raise overall awareness within the community of the issues faced in a developing, important field.

The volume covers categories on inelastic neutrino scattering and the W-boson, and other ultra-high-energy processes, on pulsars, quasars and galactic nuclei, as well as other point sources and constants from gamma ray astronomy. Individual subjects include weak intermediate vector bosons and DUMAND, the Monte Carlo simulation of inelastic neutrino scattering in DUMAND, and Higgs boson production by very high-energy neutrinos. The observability of the neutrino flux from the inner region of the galactic disk, the diffuse fluxes of high-energy neutrinos, as well as the significance of gamma ray observations for neutrino astronomy are also among the topics covered.

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

Section on Supernova Remnants and Cosmic Rays of the White Paper on the Status and Future of Ground-Based Gamma-Ray Astronomy

Pohl, M.; /Iowa State U.; Abdo, Aous A.

This is a report on the findings of the SNR/cosmic-ray working group for the white paper on the status and future of ground-based gamma-ray astronomy. The white paper is an APS commissioned document, and the overall version has also been released and can be found on astro-ph. This detailed section of the white paper discusses the status of past and current attempts to observe shell-type supernova remnants and diffuse emission from cosmic rays at GeV-TeV energies. We concentrate on the potential of future ground-based gamma-ray experiments to study the acceleration of relativistic charged particles which is one of the mainmore » unsolved, yet fundamental, problems in modern astrophysics. The acceleration of particles relies on interactions between energetic particles and magnetic turbulence. In the case of SNRs we can perform spatially resolved studies in systems with known geometry, and the plasma physics deduced from these observations will help us to understand other systems where rapid particle acceleration is believed to occur and where observations as detailed as those of SNRs are not possible.« less

Gamma-Ray Astrophysics: New Insight Into the Universe

NASA Technical Reports Server (NTRS)

Fichtel, Carl E.; Trombka, Jacob I.

1997-01-01

During the 15 years that have passed since the first edition of this book was published, there has been a major increase in our knowledge of gamma-ray astronomy. Much of this advance arises from the extensive results that have been forthcoming from the Compton Gamma-Ray Observatory. There has been the discovery of a new class of gamma-ray objects, namely high-energy gamma- ray-emitting blazars, a special class of Active Galactic Nuclei, whose basic high-energy properties now seem to be understood. A much improved picture of our galaxy now exists in the frequency range of gamma rays. The question of whether cosmic rays are galactic or metagalactic now seems settled with certainty. Significant new information exists on the gamma-ray properties of neutron star pulsars, Seyfert galaxies, and gamma-ray bursts. Substantial new insight has been obtained on solar phenomena through gamma-ray observations. Hence, this seemed to be an appropriate time to write a new edition of this book to add the important scientific implications of these many new findings. The special importance of gamma-ray astrophysics had long been recognized by many physicists and astronomers, and theorists had pursued many aspects of the subject well before the experimental results began to become available. The slower development of the experimental side was not because of a lack of incentive, but due to the substantial experimental difficulties that had to be overcome. Thus, as the gamma-ray results became available in much greater number and detail, it was possible to build upon the theoretical work that already existed and to make substantial progress in the study of many of the phenomena involved. Consequently, a much better understanding of many of the astrophysical phenomena mentioned here and others is now possible. Our principal aims in writing this book are the same as they were for the first edition: to provide a text which describes the significance of gamma-ray astrophysics and to assemble

Gamma Rays at Very High Energies

NASA Astrophysics Data System (ADS)

Aharonian, Felix

This chapter presents the elaborated lecture notes on Gamma Rays at Very High Energies given by Felix Aharonian at the 40th Saas-Fee Advanced Course on "Astrophysics at Very High Energies". Any coherent description and interpretation of phenomena related to gammarays requires deep knowledge of many disciplines of physics like nuclear and particle physics, quantum and classical electrodynamics, special and general relativity, plasma physics, magnetohydrodynamics, etc. After giving an introduction to gamma-ray astronomy the author discusses the astrophysical potential of ground-based detectors, radiation mechanisms, supernova remnants and origin of the galactic cosmic rays, TeV emission of young supernova remnants, gamma-emission from the Galactic center, pulsars, pulsar winds, pulsar wind nebulae, and gamma-ray loud binaries.

The Advanced Gamma-ray Imaging System (AGIS) is a concept for the next generation instrument in ground-based very high energy gamma-ray astronomy. It has the goal of achieving significant improvement in sensitivity over current experiments. We present the results of simulation studies of various possible designs for AGIS. The primary characteristics of the array performance, collecting area, angular resolution, background rejection, and sensitivity are discussed.

Arcsec source location measurements in gamma-ray astronomy from a lunar observatory

NASA Astrophysics Data System (ADS)

Koch, D. G.; Hughes, B. E.

1990-03-01

The physical processes typically used in the detection of high energy gamma-rays do not permit good angular resolution, which makes difficult the unambiguous association of discrete gamma-ray sources with objects emitting at other wavelengths. This problem can be overcome by placing gamma-ray detectors on the moon and using the horizon as an occulting edge to achieve arcsec resolution. For the purpose of discussion, this concept is examined for gamma rays above about 20 MeV for which pair production dominates the detection process and locally-generated nuclear gamma rays do not contribute to the background.

The status of a program which develops and characterizes integrated infrared (IR) detector array technology for space astronomical applications is described. The devices under development include intrinsic, extrinsic silicon, and extrinsic germanium detectors, coupled to silicon readout electronics. Low-background laboratory test results include measurements of responsivity, noise, dark current, temporal response, and the effects of gamma-radiation. In addition, successful astronomical imagery has been obtained on some arrays from this program. These two aspects of the development combine to demonstrate the strong potential for integrated array technology for IR space astronomy.

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.

The spectacular astrophysical discoveries made by the present generation of ground-based gamma-ray observatories have opened a new era in the exploration of the highest energy Universe and have conclusively established the field of very-high-energy (VHE) astronomy, covering the energy regime above about 50 GeV. The detection of nearly 100 galactic and extragalactic sources has generated considerable interest in the astronomy, astrophysics and particle physics communities and has stimulated ambitious ideas and plans for future gamma-ray observatories. AGIS is a concept for a next generation VHE observatory with a collecting area on the scale of a square kilometer being developed by an international collaboration. It would have significantly improved angular and energy resolution, increased field of view, and an order of magnitude increase in sensitivity over existing space or ground-based instruments in the energy range 40 GeV to 100 TeV. The scientific motivations and R&D roadmap for AGIS will be discussed.

High-energy gamma-ray astronomy is now a well-established field, and several sources have been discovered in the region from a few giga-electron volts up to several tera-electron volts. If sources involving hadronic processes exist, the production of photons would be accompanied by neutrinos too. Other possible neutrino sources could be related to the annihilation of weakly interacting, massive particles (WIMPs) at the center of galaxies with black holes. We present the results of a search for pointlike sources using 1100 upward-going muons produced by neutrino interactions in the rock below and inside the Monopole Astrophysics and Cosmic Ray Observatory (MACRO) detector in the underground Gran Sasso Laboratory. These data show no evidence of a possible neutrino pointlike source or of possible correlations between gamma-ray bursts and neutrinos. They have been used to set flux upper limits for candidate pointlike sources which are in the range 10-14-10-15 cm-2 s-1.

Very high energy gamma ray extension of GRO observations

NASA Technical Reports Server (NTRS)

Weekes, Trevor C.

1992-01-01

This has been an exiciting year for high energy gamma-ray astronomy, both from space and from ground-based observatories. It has been a particularly active period for the Whipple Observatory gamma-ray group. In phase 1 of the Compton Gamma Ray Observatory (GRO), there has not been too much opportunity for overlapping observations with the Energetic Gamma Ray Experiment Telescope (EGRET) and the other GRO telescopes; however, significant progress was made in the development of data analysis techniques and in improving the sensitivity of the technique which will have direct application in correlative observations in phase 2. Progress made during the period 1 Jul. 1991 - 31 Dec. 1991 is presented.

High energy gamma ray results from the second small astronomy satellite

A high energy (35 MeV) gamma ray telescope employing a thirty-two level magnetic core spark chamber system was flown on SAS 2. The high energy galactic gamma radiation is observed to dominate over the general diffuse radiation along the entire galactic plane, and when examined in detail, the longitudinal and latitudinal distribution seem generally correlated with galactic structural features, particularly with arm segments. The general high energy gamma radiation from the galactic plane, explained on the basis of its angular distribution and magnitude, probably results primarily from cosmic ray interactions with interstellar matter.

Development of a Telescope for Medium-Energy Gamma-Ray Astronomy

NASA Technical Reports Server (NTRS)

Hunter, Stanley D.

2010-01-01

Since the launch of AGILE and FERMI, the scientific progress in high-energy (E(sub gamma) greater than approximately 200 MeV) gamma-ray science has been, and will continue to be dramatic. Both of these telescopes cover a broad energy range from approximately 20 MeV to greater than 10 GeV. However, neither instrument is optimized for observations below approximately 200 MeV where many astrophysical objects exhibit unique, transitory behavior, such as spectral breaks, bursts, and flares. Hence, while significant progress from current observations is expected, there will nonetheless remain a significant sensitivity gap in the medium-energy (approximately 0.1-200 MeV) regime; the lower end of this range remains largely unexplored whereas the upper end will allow comparison with FERMI data. Tapping into this unexplored regime requires significant improvements in sensitivity. A major emphasis of modern detector development, with the goal of providing significant improvements in sensitivity in the medium-energy regime, focuses on high-resolution electron tracking. The Three-Dimensional Track Imager (3-DTI) technology being developed at GSFC provides high resolution tracking of the electron-positron pair from gamma-ray interactions from 5 to 200 MeV. The 3-DTI consists of a time projection chamber (TPC) and 2-D cross-strip microwell detector (MWD). The low-density and homogeneous design of the 3-DTI, offers unprecedented sensitivity by providing angular resolution near the kinematic limit. Electron tracking also enables measurement of gamma-ray polarization, a new tool to study astrophysical phenomenon. We describe the design, fabrication, and performance of a 30x30x30 cubic centimeters 3-DTI detector prototype of a medium-energy gamma-ray telescope.

Observation of nuclear reactors on satellites with a balloon-borne gamma-ray telescope

1989-01-01

Four Soviet nuclear-powered satellites flying over a double Compton gamma-ray telescope resulted in the detection of gamma rays with 0.3-8.0 MeV energies on April 15, 1988, as the balloonborne telescope searched, from a 35-km altitude, for celestial gamma-ray sources. The satellites included Cosmos 1900 and 1932. The USSR is the only nation currently employing moderated nuclear reactors for satellite power; reactors in space may cause significant problems for gamma-ray astronomy by increasing backgrounds, especially in the case of gamma-ray bursts.

Hardegree-Ullman, K. K.; Impey, C. D.; Patikkal, A.; Austin, C. L.

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.

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.

Kernel analysis in TeV gamma-ray selection

NASA Astrophysics Data System (ADS)

Moriarty, P.; Samuelson, F. W.

2000-06-01

We discuss the use of kernel analysis as a technique for selecting gamma-ray candidates in Atmospheric Cherenkov astronomy. The method is applied to observations of the Crab Nebula and Markarian 501 recorded with the Whipple 10 m Atmospheric Cherenkov imaging system, and the results are compared with the standard Supercuts analysis. Since kernel analysis is computationally intensive, we examine approaches to reducing the computational load. Extension of the technique to estimate the energy of the gamma-ray primary is considered. .

The X-ray Astronomy Recovery Mission

NASA Astrophysics Data System (ADS)

Tashiro, M.; Kelley, R.

2017-10-01

On 25 March 2016, the Japanese 6th X-ray astronomical satellite ASTRO-H (Hitomi), launched on February 17, lost communication after a series of mishap in its attitude control system. In response to the mishap the X-ray astronomy community and JAXA analyzed the direct and root cause of the mishap and investigated possibility of a recovery mission with the international collaborator NASA and ESA. Thanks to great effort of scientists, agencies, and governments, the X-ray Astronomy Recovery Mission (XARM) are proposed. The recovery mission is planned to resume high resolution X-ray spectroscopy with imaging realized by Hitomi under the international collaboration in the shortest time possible, simply by focusing one of the main science goals of Hitomi Resolving astrophysical problems by precise high-resolution X-ray spectroscopy'. XARM will carry a 6 x 6 pixelized X-ray micro-calorimeter on the focal plane of an X-ray mirror assembly, and an aligned X-ray CCD camera covering the same energy band and wider field of view, but no hard X-ray or soft gamma-ray instruments are onboard. In this paper, we introduce the science objectives, mission concept, and schedule of XARM.

1989-01-01

A new solar gamma-ray telescope is described which is intended to take advantage of current long-duration ballon facilities such as the RACOON system. The primary scientific objective is to detect and measure gamma-ray lines from solar flares, along with the associated low-energy continuum. The proposed instrument is centered on a multiheaded Ge system and is designed to operate over the energy range 50 keV to 200 200 MeV. In the nuclear transition energy region, the average energy resolution of the primary detectors is over 20 times better than that achieved with the gamma-ray spectrometer on the Solar Maximum Mission satellite.

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

Ribeiro, Valério A. R. M.; Paulo, Cláudio M.

2015-03-01

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.

Studies of Avalanche Photodiodes (APDS) as Readout Devices for Scintillating Fibers for High Energy Gamma-Ray Astronomy Telescopes

NASA Technical Reports Server (NTRS)

Vasile, Stefan; Shera, Suzanne; Shamo, Denis

1998-01-01

New gamma ray and charged particle telescope designs based on scintillating fiber arrays could provide low cost, high resolution, lightweight, very large area and multi radiation length instrumentation for planned NASA space exploration. The scintillating fibers low visible light output requires readout sensors with single photon detection sensitivity and low noise. The sensitivity of silicon Avalanche Photodiodes (APDS) matches well the spectral output of the scintillating fibers. Moreover, APDs have demonstrated single photon capability. The global aim of our work is to make available to NASA a novel optical detector concept to be used as scintillating fiber readouts and meeting the requirements of the new generations of space-borne gamma ray telescopes. We proposed to evaluate the feasibility of using RMD's small area APDs ((mu)APD) as scintillating fiber readouts and to study possible alternative (mu)APD array configurations for space borne readout scintillating fiber systems, requiring several hundred thousand to one million channels. The evaluation has been conducted in accordance with the task description and technical specifications detailed in the NASA solicitation "Studies of Avalanche Photodiodes (APD as readout devices for scintillating fibers for High Energy Gamma-Ray Astronomy Telescopes" (#8-W-7-ES-13672NAIS) posted on October 23, 1997. The feasibility study we propose builds on recent developments of silicon APD arrays and light concentrators advances at RMD, Inc. and on more than 5 years of expertise in scintillating fiber detectors. In a previous program we carried out the initial research to develop a high resolution, small pixel, solid-state, silicon APD array which exhibited very high sensitivity in the UV-VIS spectrum. This (mu)APD array is operated in Geiger mode and results in high gain (greater than 10(exp 8)), extremely low noise, single photon detection capability, low quiescent power (less than 10 (mu)W/pixel for 30 micrometers sensitive

Multi-Messenger Astronomy and Dark Matter

NASA Astrophysics Data System (ADS)

Bergström, Lars

This chapter presents the elaborated lecture notes on Multi-Messenger Astronomy and Dark Matter given by Lars Bergström at the 40th Saas-Fee Advanced Course on "Astrophysics at Very High Energies". One of the main problems of astrophysics and astro-particle physics is that the nature of dark matter remains unsolved. There are basically three complementary approaches to try to solve this problem. One is the detection of new particles with accelerators, the second is the observation of various types of messengers from radio waves to gamma-ray photons and neutrinos, and the third is the use of ingenious experiments for direct detection of dark matter particles. After giving an introduction to the particle universe, the author discusses the relic density of particles, basic cross sections for neutrinos and gamma-rays, supersymmetric dark matter, detection methods for neutralino dark matter, particular dark matter candidates, the status of dark matter detection, a detailled calculation on an hypothetical "Saas-Fee Wimp", primordial black holes, and gravitational waves.

Maier, G.; Buckley, J.; Bugaev, V.; Fegan, S.; Funk, S.; Konopelko, A.; Vassiliev, V. V.

2008-12-01

The Advanced Gamma-ray Imaging System (AGIS) is a US-led concept for a next-generation instrument in ground-based very-high-energy gamma-ray astronomy. The most important design requirement for AGIS is a sensitivity of about 10 times greater than current observatories like Veritas, H.E.S.S or MAGIC. We present results of simulation studies of various possible designs for AGIS. The primary characteristics of the array performance, collecting area, angular resolution, background rejection, and sensitivity are discussed.

We derive a Bayesian criterion for assessing whether signals observed in two separate data sets originate from a common source. The Bayes factor for a common versus unrelated origin of signals includes an overlap integral of the posterior distributions over the common-source parameters. Focusing on multimessenger gravitational-wave astronomy, we apply the method to the spatial and temporal association of independent gravitational-wave and electromagnetic (or neutrino) observations. As an example, we consider the coincidence between the recently discovered gravitational-wave signal GW170817 from a binary neutron star merger and the gamma-ray burst GRB 170817A: we find that the common-source model is enormously favored over a model describing them as unrelated signals.

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

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

NASA Astrophysics Data System (ADS)

Belay Tessema, Solomon

2015-08-01

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.

Development of a Telescope for Medium-Energy Gamma-ray Astronomy

NASA Technical Reports Server (NTRS)

Sunter, Stan

2012-01-01

Since the launch of AGILE and FERMI, the scientific progress in high-energy (Eg greater than approximately 200 MeV) gamma-ray science has been, and will continue to be dramatic. Both of these telescopes cover a broad energy range from approximately 20 MeV to greater than 10 GeV. However, neither instrument is optimized for observations below approximately 200 MeV where many astrophysical objects exhibit unique, transitory behavior, such as spectral breaks, bursts, and flares. Hence, while significant progress from current observations is expected, there will nonetheless remain a significant sensitivity gap in the medium-energy (approximately 0.1-200 MeV) regime; the lower end of this range remains largely unexplored whereas the upper end will allow comparison with FERMI data. Tapping into this unexplored regime requires significant improvements in sensitivity. A major emphasis of modern detector development, with the goal of providing significant improvements in sensitivity in the medium-energy regime, focuses on high-resolution electron tracking. The Three-Dimensional Track Imager (3-DTI) technology being developed at GSFC provides high resolution tracking of the electron-positron pair from gamma-ray interactions from 5 to 200 MeV. The 3-DTI consists of a time projection chamber (TPC) and 2-D cross-strip microwell detector (MWD). The low-density and homogeneous design of the 3-DTI, offers unprecedented sensitivity by providing angular resolution near the kinematic limit. Electron tracking also enables measurement of gamma-ray polarization, a new tool to study astrophysical phenomenon. We describe the design, fabrication, and performance of a 30x30x30 cm3 3-DTI detector prototype of a medium-energy gamma-ray telescope.

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.

Outcomes of promotional efforts for astronomy among high school students through the astronomy olympiad

NASA Astrophysics Data System (ADS)

Kim, Yoojea

2015-08-01

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.

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.

Results from Multiwavelength Workshop for Next Generation Gamma Ray Experiments

NASA Astrophysics Data System (ADS)

Fortson, L.

2002-12-01

The next few years will see the build up of several new gamma-ray detectors both on the ground and in space. By 2006 VERITAS, HESS and MAGIC expect to be operational and GLAST will be in orbit. At the same time, a number of X-ray satellites will be in operation, complementing these new gamma-ray instruments. A better understanding of many high-energy sources can be obtained by making contemporaneous observations with multiple x-ray and gamma-ray instruments. A workshop was recently held at the Adler Planetarium and Astronomy Museum in Chicago to discuss the future of multiwavelength campaigns. The workshop was intended as an opportunity for information exchange within the community to get the best possible science returns from the wealth of data that is expected to come in from the next generation of experiments. By the end of the workshop participants gained a general understanding of the capabilities of the various instruments and their observational strategies. We also came up with a good start on some concrete mechanisms for coordinating gamma-ray observations with ground based and space based observatories at other wavelengths - including X-ray and optical groups. I will report on the results from this workshop in my presentation at the AAS. The workshop was sponsored by the Adler Planetarium and Astronomy Museum.

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 explosion, crater size, and magnitude of the ``planetquake'' generated. It also displays a relevant image (e.g. terrestrial crater, lunar crater, etc.). SCALE OF THE UNIVERSE: 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. SCIENTIFIC NOTATION: Students are interactively guided through conversions between scientific notation and regular numbers. ORBITAL SIMULATIONS: These tools allow the student to investigate different aspects of the three-body problem of celestial mechanics.

1982-01-01

This artist's conception depicts the High Energy Astronomy Observatory (HEAO)-1 in orbit. The first observatory, designated HEAO-1, was launched on August 12, 1977 aboard an Atlas/Centaur launch vehicle and was designed to survey the sky for additional x-ray and gamma-ray sources as well as pinpointing their positions. The HEAO-1 was originally identified as HEAO-A but the designation was changed once the spacecraft achieved orbit. The HEAO project involved the launching of three unmarned scientific observatories into low Earth orbit between 1977 and 1979 to study some of the most intriguing mysteries of the universe; pulsars, black holes, neutron stars, and super nova. Hardware support for the imaging instruments was provided by American Science and Engineeing. The HEAO spacecraft were built by TRW, Inc. under project management of the Marshall Space Flight Center.

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).

Implications of the IRAS data for galactic gamma ray astronomy and EGRET

NASA Technical Reports Server (NTRS)

Stecker, Floyd W.

1990-01-01

Using the results of gamma-ray, millimeter wave and far surveys of the galaxy, logically consistent picture of the large scale distribution of galactic gas and cosmic rays was derived, tied to the overall processes of stellar birth and destruction on a galactic scale. Using the results of the IRAS far-infrared survey of te galaxy, the large scale radial distributions of galactic far-infrared emission independently was obtained for both the Northern and Southern Hemisphere sides of the Galaxy. The dominant feature in these distributions was found to be a broad peak coincident with the 5 kpc molecular gas cloud ring. Evidence was found for spiral arm features. Strong correlations are evident between the large scale galactic distributions of far-infrared emission, gamma-ray emission and total CO emission. There is particularly tight correlation between the distribution of warm molecular clouds and far-infrared emission on a galactic scale. The 5 kpc ring was evident in existing galactic gamma-ray data. The extent to which the more detailed spiral arm features are evident in the more resolved EGRET (Energetic Gamma-Ray Experimental Telescope) data will help to determine more precisely the propagation characteristics of cosmic rays.

Machine learning techniques offer a precious tool box for use within astronomy to solve problems involving so-called big data. They provide a means to make accurate predictions about a particular system without prior knowledge of the underlying physical processes of the data. In this article, and the companion papers of this series, we present the set of Generalized Linear Models (GLMs) as a fast alternative method for tackling general astronomical problems, including the ones related to the machine learning paradigm. To demonstrate the applicability of GLMs to inherently positive and continuous physical observables, we explore their use in estimating the photometric redshifts of galaxies from their multi-wavelength photometry. Using the gamma family with a log link function we predict redshifts from the PHoto-z Accuracy Testing simulated catalogue and a subset of the Sloan Digital Sky Survey from Data Release 10. We obtain fits that result in catastrophic outlier rates as low as ∼1% for simulated and ∼2% for real data. Moreover, we can easily obtain such levels of precision within a matter of seconds on a normal desktop computer and with training sets that contain merely thousands of galaxies. Our software is made publicly available as a user-friendly package developed in Python, R and via an interactive web application. This software allows users to apply a set of GLMs to their own photometric catalogues and generates publication quality plots with minimum effort. By facilitating their ease of use to the astronomical community, this paper series aims to make GLMs widely known and to encourage their implementation in future large-scale projects, such as the Large Synoptic Survey Telescope.

Observations of the gamma-ray sky reveal the most powerful sources and the most violent events in the Universe While at lower wavebands the observed emission is generally dominated by thermal processes the gamma-ray sky provides us with a view on the non-thermal Universe Here particles are accelerated to extreme relativistic energies by mechanisms which are still poorly understood and nuclear reactions are synthesizing the basic constituents of our world Cosmic accelerators and cosmic explosions are the major science themes that are addressed in the gamma-ray regime With the INTEGRAL observatory ESA has provided a unique tool to the astronomical community and has put Europe in the lead in the field of gamma-ray astronomy INTEGRAL provides an unprecedented survey of the soft gamma-ray sky revealing hundreds of sources new classes of objects extraordinary views of antimatter annihilation in our Galaxy and fingerprints of recent nucleosynthesis processes While INTEGRAL has provided the global overview over the soft gamma-ray sky there is a growing need to perform deeper more focused investigations of gamma-ray sources In soft X-rays a comparable step was taken going from the Einstein satellite to the XMM Newton observatory Technological advances in the past years in the domain of gamma-ray focusing using Laue diffraction and multilayer-coated mirror techniques have paved the way towards a gamma-ray mission providing major improvements compared to past missions regarding sensitivity and angular resolution Such a

The future of high energy gamma ray astronomy and its potential astrophysical implications

NASA Technical Reports Server (NTRS)

Fichtel, C. E.

1982-01-01

Future satellites should carry instruments having over an order of magnitude greater sensitivity than those flown thus far as well as improved energy and angular resolution. The information to be obtained from these experiments should greatly enhance knowledge of: the very energetic and nuclear processes associated with compact objects; the structure of our galaxy; the origin and dynamic pressure effects of the cosmic rays; the high energy particles and energetic processes in other galaxies; and the degree of matter-antimatter symmetry of the universe. The relevant aspects of extragalactic gamma ray phenomena are emphasized along with the instruments planned. The high energy gamma ray results of forthcoming programs such as GAMMA-1 and the Gamma Ray Observatory should justify even more sophisticated telescopes. These advanced instruments might be placed on the space station currently being considered by NASA.

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.

Silicon Photo-Multiplier Readouts for Scintillators in High-Energy Astronomy

NASA Technical Reports Server (NTRS)

Bloser, Peter F.; Legere, Jason S.; Bancroft, Christopher M.; McConnell, Mark L.; Ryan, James M.

2008-01-01

New scintillator materials have recently been shown to hold great potential for low-cost, reliable gamma-ray detectors in high-energy astronomy. New devices for the detection of scintillation light promise to make scintillator-based instruments even more attractive by reducing mass and power requirements,in particular, silicon photo-multipliers (SiPMs) are starting to become commercially available that offer gains and quantum efficiencies similar to those of photo-multiplier tubes (PMTs), but with greatly reduced mass, high ruggedness, low voltage requirements, and no sensitivity to magnetic fields. We have conducted laboratory tests of a sample of commercially available SiPMs coupled to LaBr3;Ce, a scintillator of relevance to to future high-energy astrophysics missions. We present results for gamma-ray spectroscopy. compare the SiPM performance to that of a PMT, and discuss the extent to which SiPMs offer significant advantages for scintillator-based space missions.

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

NASA Astrophysics Data System (ADS)

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.

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.

The AGIS project under design study, is a large array of imaging atmospheric Cherenkov telescopes for gamma-rays astronomy between 40GeV and 100 TeV. In this paper we present the ongoing simulation effort to model the considered design approaches as a function of the main parameters such as array geometry, telescope optics and camera design in such a way the gamma ray observation capabilities can be optimized against the overall project cost.

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.

The MAGIC telescope for gamma-ray astronomy above 30 GeV

NASA Astrophysics Data System (ADS)

Moralejo, A.; MAGIC Collaboration

The MAGIC telescope is presently at its commissioning phase at the Roque de los Muchachos Observatory (ORM) on the island of La Palma. MAGIC will become the largest ground-based gamma ray telescope in the world, being sensitive to photons of energies as low as 30 GeV. The spectral range between 10 and 300 GeV remains to date mostly unexplored. Observations in this region of the spectrum are expected to provide key data for the understanding of a wide variety of astrophysical phenomena belonging to the so-called ``non thermal Universe'', like the processes in the nuclei of active galaxies, the radiation mechanisms of pulsars and supernova remnants, and the enigmatic gamma-ray bursts. And overview of the telescope and its Physics goals is presented.

A prototype gamma-ray telescope employing the coded aperture mask technique has been constructed and its response to a point source of 20 MeV gamma-rays has been measured. The point spread function is approximately a Gaussian with a standard deviation of 12 arc minutes. This resolution is consistent with the cell size of the mask used and the spatial resolution of the detector. In the context of the present experiment, the error radius of the source position (90 percent confidence level) is 6.1 arc minutes.

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.

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

AGATE: A High Energy Gamma-Ray Telescope Using Drift Chambers

The exciting results from the highly successful Energetic Gamma-Ray Experiment Telescope (EGRET) instrument on the Compton Gamma-Ray Observatory (CGRO) has contributed significantly to increasing our understanding of high energy gamma-ray astronomy. A follow-on mission to EGRET is needed to continue these scientific advances as well as to address the several new scientific questions raised by EGRET. Here we describe the work being done on the development of the Advanced Gamma-Ray Astronomy Telescope Experiment (AGATE), visualized as the successor to EGRET. In order to achieve the scientific goals, AGATE will have higher sensitivity than EGRET in the energy range 30 MeV to 30 GeV, larger effective area, better angular resolution, and an extended low and high energy range. In its design, AGATE will follow the tradition of the earlier gamma-ray telescopes, SAS-2, COS B, and EGRET, and will have the same four basic components of an anticoincidence system, directional coincidence system, track imaging, and energy measurement systems. However, due to its much larger size, AGATE will use drift chambers as its track imaging system rather than the spark chambers used by EGRET. Drift chambers are an obvious choice as they have less deadtime per event, better spatial resolution, and are relatively easy and inexpensive to build. Drift chambers have low power requirements, so that many layers of drift chambers can be included. To test the feasibility of using drift chambers, we have constructed a prototype instrument consisting of a stack of sixteen 1/2m × 1/2m drift chambers and have measured the spatial resolution using atmospheric muons. The results on the drift chamber performance in the laboratory are presented here.

The Energetic Gamma-Ray Experiment Telescope (EGRET) Science Symposium

Fichtel, Carl E. (Editor); Hunter, Stanley D. (Editor); Sreekumar, Parameswaran (Editor); Stecker, Floyd W. (Editor)

1990-01-01

The principle purpose of this symposium is to provide the EGRET (Energetic Gamma-Ray Experiment Telescope) scientists with an opportunity to study and improve their understanding of high energy gamma ray astronomy. The Symposium began with the galactic diffusion radiation both because of its importance in studying galactic cosmic rays, galactic structure, and dynamic balance, and because an understanding of its characteristics is important in the study of galactic sources. The galactic objects to be reviewed included pulsars, bursts, solar flares, and other galactic sources of several types. The symposium papers then proceeded outward from the Milky Way to normal galaxies, active galaxies, and the extragalactic diffuse radiation.

Gamma ray astronomy above 30 TeV and the IceCube results

NASA Astrophysics Data System (ADS)

Vernetto, Silvia; Lipari, Paolo

2017-03-01

The study of the diffuse Galactic gamma ray emission is of fundamental importance to understand the properties of cosmic ray propagation in the Milky Way, and extending the measurements to E ≳ 30 TeV is of great interest. In the same energy range the IceCube detector has also recently observed a flux of astrophysical neutrinos, and it is important to test experimentally if the neutrino production is accompanied by a comparable emission of high energy photons. For E ≳ 30 TeV, the absorption effects due to e+e- pair production when the high energy photons interact with radiation fields present in space are not negligible and must be taken into account. Gamma rays, in good approximation, are completely absorbed if they have an extragalactic origin, but the absorption is significant also for Galactic photons. In this case the size and angular dependence of the absorption depends on the space distribution of the emission. In this work we estimate the absorption for different models of the space distribution of the gamma ray emission, and discuss the potential of future detectors.

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.

High Energy Astronomy Observatory (HEAO)

NASA Image and Video Library

1975-01-01

The family of High Energy Astronomy Observatory (HEAO) instruments consisted of three unmarned scientific observatories capable of detecting the x-rays emitted by the celestial bodies with high sensitivity and high resolution. The celestial gamma-ray and cosmic-ray fluxes were also collected and studied to learn more about the mysteries of the universe. High-Energy rays cannot be studied by Earth-based observatories because of the obscuring effects of the atmosphere that prevent the rays from reaching the Earth's surface. They had been observed initially by sounding rockets and balloons, and by small satellites that do not possess the needed instrumentation capabilities required for high data resolution and sensitivity. The HEAO carried the instrumentation necessary for this capability. In this photograph, an artist's concept of three HEAO spacecraft is shown: HEAO-1, launched on August 12, 1977; HEAO-2, launched on November 13, 1978; and HEAO-3, launched on September 20. 1979.

SAS 2 observations of the earth albedo gamma radiation above 35 MeV

NASA Technical Reports Server (NTRS)

Thompson, D. J.; Simpson, G. A.; Ozel, M. E.

1981-01-01

The earth albedo gamma radiation above 35 MeV in the equatorial region is investigated using observations from the second Small Astronomy Satellite. The zenith angle distribution of the gamma radiation has a peak toward the horizon which is about an order of magnitude more intense than the radiation coming from the nadir, and nearly two orders of magnitude more intense than the gamma radiation from most parts of the sky. The gamma radiation originating from the western horizon is a factor of four more intense than the radiation from the eastern horizon and a factor of three more intense than that from the northern and southern directions. This reflects the geomagnetic effects on the incident cosmic rays whose interactions produce the albedo gamma rays. The variation of the upcoming gamma ray intensity with vertical cutoff rigidity is consistent with the empirical relationship found by Gur'yan et al. (1979).

Astronomy in Iraq

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

Astronomy in Everyday Life

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.

The MAGIC telescope, presently at its commissioning phase, will become fully operative by the end of 2003. Placed at the Roque de los Muchachos Observatory (ORM) on the island of La Palma, MAGIC is the largest among new generation ground-based gamma ray telescopes, and will reach an energy threshold as low as 30 GeV. The range of the electromagnetic spectrum between 10 and 250 GeV remains to date mostly unexplored. Observations in this energy region are expected to provide key data for the understanding of a wide variety of astrophysical phenomena belonging to the so-called ``non thermal Universe'', like the processes in the nuclei of active galaxies, the radiation mechanisms of pulsars and supernova remnants, and the enigmatic gamma-ray bursts. An overview of the telescope and its physics goals is presented.

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.

High energy gamma-ray astronomy observations of Geminga with the VERITAS array

NASA Astrophysics Data System (ADS)

Finnegan, Gary Marvin

The closest known supernova remnant and pulsar is Geminga. The Geminga pulsar is the first pulsar to have ever been detected initially by gamma rays and the first pulsar in a class of radio-quiet pulsars. In 2007, the Milagro collaboration detected a large angularly extended (˜ 2.6°) emission of high energy gamma rays (˜ 20 TeV ) that was positionally coincident with Geminga. The Very Energetic Radiation Imaging Telescope Array System (VERITAS) is a ground- based observatory with four imaging Cherenkov telescopes with an energy range between 100 GeV to more than 30 TeV. The imaging Cherenkov telescopes detect the Cherenkov light from charged particles in electromagnetic air showers initiated by high energy particles such as gamma rays and cosmic rays. Most gamma-ray sources detected by VERITAS are point like sources, which have an angular extension smaller than the angular resolution of the telescopes (˜ 0.1°). For a point source, the background noise can be measured in the same field of view (FOV) as the source. For an angularly extended object, such as Geminga, an external FOV from the source region must be used to estimate the background noise, to avoid contamination from the extended source region. In this dissertation, I describe a new analysis procedure that is designed to increase the observation sensitivity of angularly extended objects like Geminga. I apply this procedure to a known extended gamma-ray source, Boomerang, as well as Geminga. The results indicate the detection of very high energy emission from the Geminga region at the level of 4% of the Crab nebula with a weighted average spectral index of -2.8 ± 0.2. A possible extension less than one degree wide is shown. This detection, however, awaits a confirmation by the VERITAS collaboration. The luminosity of the Geminga extended source, the Vela Nebula, and the Crab nebula was calculated for energies greater than 1 TeV. The data suggest that older pulsars, such as Geminga and Vela, convert the

Teaching Astronomy Online

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.

Fractal astronomy.

Beech, M.

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?"

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 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.

Astronomía gamma con telescopios Cherenkov: hacia un observatorio astronómico abierto a la comunidad

NASA Astrophysics Data System (ADS)

Rovero, A. C.

Gamma-ray astronomy is opening the way to a universe far more energetic than anyone could have imagined half a century ago. The understanding of the processes of nature which carry a large portion of the energy in the universe, has astrophysical and cosmological implications. The next gen- eration of Cherenkov telescopes, an order of magnitude more sensitive and with higher resolution than the current systems, will mean a significant step forward for ground-based gamma-ray astronomy. This paper presents the current status of this field as well as the next generation of telescopes in this energy range, which are being designed for the first international observa- tory open to the astronomical community. The Cherenkov Telescope Array project and the Argentine sites proposed for the southern observatory are described in this paper. FULL TEXT IN SPANISH

An innate advantage for astronomy teachers is having numerous breathtaking images of the cosmos available to capture students' curiosity, imagination, and wonder. Internet-based astronomy image libraries are numerous and easy to navigate. The Astronomy Picture of the Day, the Hubble Space Telescope image archive, and the NASA Planetary Photojournal are just a few of the many available.1-3 At the same time, computer video projectors and SMART Boards are becoming ever more commonplace in classrooms. Taken together, it has never been easier to bring astronomy directly into classrooms to actively engage students to improve student understanding and motivate student learning.

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.

Astronomy from the Moon: A New Frontier for 21st Century Astrophysics

NASA Astrophysics Data System (ADS)

Durst, Steve

2018-06-01

The International Lunar Observatory Association of Hawai'i USA continues into its second decade with research and development of South Pole instruments for astronomy, observation and communication from the Moon. Since the pioneering first astronomy observations from the Moon by Apollo 16 Commander John Young (an ILOA founding-emeritus director until his recent passing), with China Lunar Ultraviolet Telescope LUT operations and current American and European considerations for far-side radio telescopes, today's climate is most promising for a diversity of lunar-based astronomy locations, instruments and technologies. ILOA is aiming to advance this frontier through its Galaxy First Light Imaging program, being developed through contracts with Moon Express and Canadensys Aerospace Corp.A wide variety of extreme and unique lunar conditions enable many astronomy activities and installations, on the Moon's near-side, far-side, north pole, and south pole: The extremely thin lunar exosphere favors observations in millimeter / submillimeter to optical, UV, X-ray, and gamma-ray wavelengths; the highly stable platform that is the Moon provides for long-duration observations; ultra cold, shaded areas for cryogenic infrared instruments; far-side radio-quiet environment for radio telescopes and VLF astronomy; 1/6-Earth gravity for production and utilization of new, very lightweight materials and instruments, including large refractors, 100-m class liquid mirror telescopes, and possibly 1,000-m class radio telescopes and interferometer antenna arrays vastly larger than Atacama LMA; North and especially South Pole sites, with high peaks and long solar power windows, offer perhaps the widest variety of lunar conditions and opportunities for astronomical innovation on the Moon: a veritable "condominium of observatories".21st century astrophysics seems likely to find Luna a very busy and productive new frontier, as American Astronomical Society and IAU members will validate, with

Innovative Technology for Teaching Introductory Astronomy

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.

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.

Di Sciascio, G.; Di Girolamo, T.; Megna, R.

2005-02-21

The ARGO-YBJ experiment, currently under construction at the YangBaJing Laboratory (Tibet, P.R. China, 4300 m a.s.l.), could be upgraded with a large ({approx} 2500 m2) muon detector both to extend the sensitivity to {gamma}-ray sources to energies greater than {approx} 20 TeV and to perform a cosmic ray primary composition study. In this paper we present an evaluation of the rejection power for proton-induced showers achievable with the upgraded ARGO-YBJ detector. Minimum detectable {gamma}-ray fluxes are calculated for different experimental setups.

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.

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.

REVIEWS OF TOPICAL PROBLEMS: Gamma astronomy of the Sun and study of solar cosmic rays

NASA Astrophysics Data System (ADS)

Kuzhevskiĭ, B. M.

1982-06-01

A detailed discussion is given of the various nuclear reactions proceeding in the Sun's atmosphere under the influence of flare-accelerated particles. The role of such reactions in formation of the line spectrum and continuum of gamma-rays from the disturbed and quiet Sun is discussed. The gamma-ray fluxes in individual lines and in the continuum are estimated. The possibility of applying data on gamma-ray emission from the Sun to analysis of particle acceleration in solar flares and the conditions of their ejection into interplanetary space is analyzed.

Recent high energy gamma-ray results from SAS-2

1977-01-01

Recent developments in gamma-ray astronomy due to the results from SAS-2 have focused on two areas. First, the emission from the plane of the Galaxy is the dominant feature in the gamma-ray sky. The galactic latitude and longitude distributions are consistent with the concept that the high-energy radiation originates from cosmic rays interacting with interstellar matter, and the measurements support a galactic origin for cosmic rays. Second, searches of the SAS-2 data for emission from localized sources have shown three strong discrete gamma-ray sources: the Crab nebula and PSR 0531 + 21, the Vela supernova remnant and PSR 0833-45, and a source near galactic coordinates 193 deg longitude, +3 deg latitude, which does not appear to be associated with other known celestial objects. Evidence has also been found for pulsed gamma-ray emission from two other radio pulsars, PSR 1818-04 and PSR 1747-46. A localized source near longitudes 76-80 deg may be associated with the X-ray source Cyg X-3.

Multiwavelength Study of Gamma-Ray Bright Blazars

Morozova, Daria; Larionov, V. M.; Hagen-Thorn, V. A.; Jorstad, S. G.; Marscher, A. P.; Troitskii, I. S.

2011-01-01

We investigate total intensity radio images of 6 gamma-ray bright blazars (BL Lac, 3C 279, 3C 273, W Com, PKS 1510-089, and 3C 66A) and their optical and gamma-ray light curves to study connections between gamma-ray and optical brightness variations and changes in the parsec-scale radio structure. We use high-resolution maps obtained by the BU group at 43 GHz with the VLBA, optical light curves constructed by the St.Petersburg State U. (Russia) team using measurements with the 0.4 m telescope of St.Petersburg State U. (LX200) and the 0.7 m telescope of the Crimean Astrophysical Observatory (AZT-8), and gamma-ray light curves, which we have constructed with data provided by the Fermi Large Area Telescope. Over the period from August 2008 to November 2009, superluminal motion is found in all 6 objects with apparent speed ranging from 2c to 40c. The blazars with faster apparent speeds, 3C 273, 3C 279, PKS 1510-089, and 3C 66A, exhibit stronger variability of the gamma-ray emission. There is a tendency for sources with sharply peaked gamma-ray flares to have faster jet speed than sources with gamma-ray light curves with no sharp peaks. Gamma-ray light curves with sharply peaked gamma-ray flares possess a stronger gamma-ray/optical correlations. The research at St.Petersburg State U. was funded by the Minister of Education and Science of the Russian Federation (state contract N#P123). The research at BU was funded in part by NASA Fermi Guest Investigator grant NNX08AV65G and by NSF grant AST-0907893. The VLBA is an instrument of the National Radio Astronomy Observatory, a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

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.

Evaluation of the cosmic-ray induced background in coded aperture high energy gamma-ray telescopes

Owens, Alan; Barbier, Loius M.; Frye, Glenn M.; Jenkins, Thomas L.

1991-01-01

While the application of coded-aperture techniques to high-energy gamma-ray astronomy offers potential arc-second angular resolution, concerns were raised about the level of secondary radiation produced in a thick high-z mask. A series of Monte-Carlo calculations are conducted to evaluate and quantify the cosmic-ray induced neutral particle background produced in a coded-aperture mask. It is shown that this component may be neglected, being at least a factor of 50 lower in intensity than the cosmic diffuse gamma-rays.

A study of the sensitivity of an imaging telescope (GRITS) for high energy gamma-ray astronomy

NASA Technical Reports Server (NTRS)

Yearian, Mason R.

1990-01-01

When a gamma-ray telescope is placed in Earth orbit, it is bombarded by a flux of cosmic protons much greater than the flux of interesting gammas. These protons can interact in the telescope's thermal shielding to produce detectable gamma rays, most of which are vetoed. Since the proton flux is so high, the unvetoed gamma rays constitute a significant background relative to some weak sources. This background increases the observing time required to pinpoint some sources and entirely obscures other sources. Although recent telescopes have been designed to minimize this background, its strength and spectral characteristics were not previously calculated in detail. Monte Carlo calculations are presented which characterize the strength, spectrum and other features of the cosmic proton background using FLUKA, a hadronic cascade program. Several gamma-ray telescopes, including SAS-2, EGRET and the Gamma Ray Imaging Telescope System (GRITS), are analyzed, and their proton-induced backgrounds are characterized. In all cases, the backgrounds are either shown to be low relative to interesting signals or suggestions are made which would reduce the background sufficiently to leave the telescope unimpaired. In addition, several limiting cases are examined for comparison to previous estimates and calibration measurements.

The MSFC was heavily engaged in the technical and scientific aspects, testing and calibration, of the HEAO-2 telescope The HEAO-2 was the first imaging and largest x-ray telescope built to date. The X-Ray Calibration Facility was built in 1976 for testing MSFC's HEAO-2. The facility is the world's largest, most advanced laboratory for simulating x-ray emissions from distant celestial objects. It produced a space-like environment in which components related to x-ray telescope imaging are tested and the quality of their performance in space is predicted. The original facility contained a 1,000-foot long by 3-foot diameter vacuum tube (for the x-ray path) cornecting an x-ray generator and an instrument test chamber. Recently, the facility was upgraded to evaluate the optical elements of NASA's Hubble Space Telescope, Chandra X-Ray Observatory and Compton Gamma-Ray Observatory.

2002-11-01

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.

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

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

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.

The National Radio Astronomy Observatory (NRAO) is teaming with NASA's upcoming Gamma-ray Large Area Space Telescope (GLAST) to allow astronomers to use both the orbiting facility and ground-based radio telescopes to maximize their scientific payoff. Under the new, streamlined process, astronomers can compete for coordinated observing time and support from both GLAST and NRAO's radio telescopes.

Byrd Green Bank Telescope Very Long Baseline Array Very Large Array Atacama Large Millimeter/submillimeter Array GLAST is scheduled for launch no earlier than December 14. It will perform a survey of the entire sky at gamma-ray wavelengths every 3 hours using its primary instrument, the Large Area Telescope (LAT). NRAO operates the Very Large Array (VLA) in New Mexico, the continent-wide Very Long Baseline Array (VLBA), and the Robert C. Byrd Green Bank Telescope (GBT) in West Virginia. The NRAO is a research facility of the National Science Foundation (NSF). "Coordinated gamma-ray and radio observations of celestial objects will greatly enhance the ability to fully understand those objects. Astronomy today requires such multiwavelength studies, and this agreement paves the way for exciting, cutting-edge research," said Fred K.Y. Lo, NRAO Director. GLAST will be vastly more capable than previous gamma-ray satellites, and will carry an instrument, the GLAST Burst Monitor, specifically designed to detect gamma-ray bursts. GLAST observers will study objects such as active galaxies, pulsars, and supernova remnants, which are also readily studied with radio telescopes. By working together, NASA's GLAST mission and NSF's NRAO facilities can study flares from blazars over the widest possible range of energies, which is crucial to understanding how black holes, notorious for drawing matter in, can

The application of the coded aperture mask to high energy gamma-ray astronomy will provide the capability of locating a cosmic gamma-ray point source with a precision of a few arc-minutes above 20 MeV. Recent tests using a mask in conjunction with drift chamber detectors have shown that the expected point spread function is achieved over an acceptance cone of 25 deg. A telescope employing this technique differs from a conventional telescope only in that the presence of the mask modifies the radiation field in the vicinity of the detection plane. In addition to reducing the primary photon flux incident on the detector by absorption in the mask elements, the mask will also be a secondary radiator of gamma-rays. The various background components in a CAMTRAC (Coded Aperture Mask Track Chamber) telescope are considered. Monte-Carlo calculations are compared with recent measurements obtained using a prototype instrument in a tagged photon beam line.

Europe's Astronomy Teachers Meet at ESO

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.

Development of a high resolution liquid xenon imaging chamber for gamma-ray astronomy

NASA Technical Reports Server (NTRS)

Aprile, Elena

1991-01-01

The objective was to develop the technology of liquid xenon (LXe) detectors for spectroscopy and imaging of gamma rays from astrophysical sources emitting in the low to medium energy regime. In particular, the technical challenges and the physical processes relevant to the realization of the LXe detector operated as a Time Projection Chamber (TPC) were addressed and studied. Experimental results were obtained on the following topics: (1) long distance drift of free electrons in LXe (purity); (2) scintillation light yield for electrons and alphas in LXe (triggering); and (3) ionization yield for electrons and gamma rays in LXe (energy resolution). The major results from the investigations are summarized.

Distribution of cosmic gamma rays in the galactic anticenter region as observed by SAS-2

The high energy (above 35 MeV) gamma ray telescope flown on the second Small Astronomy Satellite has collected over one thousand gamma rays from the direction of the galactic anticenter. In addition to the diffuse galactic emission the distribution indicates a strong pulsed contribution from the Crab nebula with the same period and phase as the NP0532 pulsar. There also seems to be an excess in the direction of (gal. long. ? 195 deg; gal. lat ? +5 deg) where there is a region containing old supernova remnants. Search for gamma ray pulsations from other pulsars in the region do not show any statistically significant signal. The general intensity distribution of the gamma rays away from the plane appear to be similar to nonthermal radio emission brightness contours.

The Advanced Gamma-Ray Imaging System (AGIS)

NASA Astrophysics Data System (ADS)

Otte, Nepomuk

The Advanced Gamma-ray Imaging System (AGIS) is a concept for the next generation of imag-ing atmospheric Cherenkov telescope arrays. It has the goal of providing an order of magnitude increase in sensitivity for Very High Energy Gamma-ray ( 100 GeV to 100 TeV) astronomy compared to currently operating arrays such as CANGAROO, HESS, MAGIC, and VERITAS. After an overview of the science such an array would enable, we discuss the development of the components of the telescope system that are required to achieve the sensitivity goal. AGIS stresses improvements in several areas of IACT technology including component reliability as well as exploring cost reduction possibilities in order to achieve its goal. We discuss alterna-tives for the telescopes and positioners: a novel Schwarzschild-Couder telescope offering a wide field of view with a relatively smaller plate scale, and possibilities for rapid slewing in order to address the search for and/or study of Gamma-ray Bursts in the VHE gamma-ray regime. We also discuss options for a high pixel count camera system providing the necessary finer solid angle per pixel and possibilities for a fast topological trigger that would offer improved realtime background rejection and lower energy thresholds.

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.

Astronomy Demonstrations and Models.

ERIC Educational Resources Information Center

Eckroth, Charles A.

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,…

The Hitomi (ASTRO-H) mission is the sixth Japanese X-ray astronomy satellite developed by a large international collaboration, including Japan, USA, Canada, and Europe. The mission aimed to provide the highest energy resolution ever achieved at E > 2 keV, using a microcalorimeter instrument, and to cover a wide energy range spanning four decades in energy from soft X-rays to gamma-rays. After a successful launch on 2016 February 17, the spacecraft lost its function on 2016 March 26, but the commissioning phase for about a month provided valuable information on the on-board instruments and the spacecraft system, including astrophysical results obtained from first light observations. The paper describes the Hitomi (ASTRO-H) mission, its capabilities, the initial operation, and the instruments/spacecraft performances confirmed during the commissioning operations for about a month.

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.

We presented in 2014 the very first data from a polarised gamma-ray beam between 1.7 and 74MeV. We now show the results of their analysis, and in particular the polarimetry measurements. With these results, we are establishing a new, high-performance way to do gamma-ray astronomy and, for the first time, polarimetry, in the e+e- pair regime.

SAS-2 observations of celestial diffuse gamma radiation above 30 MeV

1974-01-01

The small astronomy satellite, SAS-2, used a 32-deck magnetic core digitized spark chamber to study gamma rays with energies above 30 MeV. Data for four regions of the sky away from the galactic plane were analyzed. These regions show a finite, diffuse flux of gamma rays with a steep energy spectrum, and the flux is uniform over all the regions. Represented by a power law, the differential energy spectrum shows an index of 2.5 + or - 0.4. The steep SAS-2 spectrum and the lower energy data are reasonably consistent with a neutral pion gamma-ray spectrum which was red-shifted (such as that proposed by some cosmological theories). It is concluded that the diffuse celestial gamma ray spectrum observed presents the possibility of cosmological studies and possible evidence for a residual cosmic ray density, and supports the galactic superclusters of matter and antimatter remaining from baryon-symmetric big bang.

Celestial diffuse gamma radiation above 30 MeV observed by SAS-2

Fichtel, C. E.; Kniffen, D. A.; Hartman, R. C.

1973-01-01

The Small Astronomy Satellite (SAS)-2, launched on November 15, 1972, carried into orbit a 32-deck magnetic-core digitized spark chamber gamma ray telescope to study celestial gamma radiation in the energy range above 30 MeV. In the study of several regions with b sub 2 15 deg, a finite, diffuse flux of gamma rays with a steep energy spectrum in the energy region from 35 to 200 MeV is observed. Representing the energy spectrum by a power law of the form dJ/dE = AE to - alpha power over this energy range, alpha is found along with the integral flux above 100 MeV. Combining this result with existing low energy gamma ray data yields an energy spectrum which is not a simple power law in energy, as in the X-ray region, but which demonstrates first an increase and then a decrease in slope, consistent within uncertainties with that predicted by cosmological theories, including the continuous production of high energy gamma rays primarily from neutral pi mesons throughout the history of the universe.

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.

Northern hemisphere TeV gamma-ray observatories such as Milagro and Tibet AS{gamma} have demonstrated the importance of all-sky instruments by discovering previously unidentified sources that may be the PeVatrons producing cosmic rays up to the knee in the cosmic ray spectrum. We evaluate the potential of IceCube to identify similar sources in the southern sky by detailing an analytic approach to determine fluxes of muons from TeV gamma-ray showers. We apply this approach to known gamma-ray sources such as supernova remnants. We find that, similar to Milagro, detection is possible in 10 years for pointlike PeVatrons with fluxes stronger than severalmore » 10{sup -11} particles TeV{sup -1} cm{sup -2} s{sup -1}.« less

The present volume gathers together the talks presented at the second colloquium on the Future Professional Communication in Astronomy (FPCAII), held at the Harvard-Smithsonian Center for Astrophysics (Cambridge, MA) on 13-14 April 2010. This meeting provided a forum for editors, publishers, scientists, librarians and officers of learned societies to discuss the future of the field. The program included talks from leading researchers and practitioners and drew a crowd of approximately 50 attendees from 10 countries. These proceedings contain contributions from invited and contributed talks from leaders in the field, touching on a number of topics. Among them: The role of disciplinary repositories such as ADS and arXiv in astronomy and the physical sciences; Current status and future of Open Access Publishing models and their impact on astronomy and astrophysics publishing; Emerging trends in scientific article publishing: semantic annotations, multimedia content, links to data products hosted by astrophysics archives; Novel approaches to the evaluation of facilities and projects based on bibliometric indicators; Impact of Government mandates, Privacy laws, and Intellectual Property Rights on the evolving digital publishing environment in astronomy; Communicating astronomy to the public: the experience of the International Year of Astronomy 2009.

An Overview of the Current Understanding of Gamma-Ray Bursts in the Fermi Era

Bhat, P. N.; Guiriec, Sylvain

2011-01-01

Gamma-ray bursts are the most luminous explosions in the Universe, and their origin as well as mechanism are the focus of intense research and debate. More than three decades since their serendipitous discovery, followed by several breakthroughs from space-borne and ground-based observations, they remain one of the most interesting astrophysical phenomena yet to be completely understood. Since the launch of Fermi with its unprecedented energy band width spanning seven decades, the study of gamma-ray burst research has entered a new phase. Here we review the current theoretical understanding and observational highlights of gamma-ray burst astronomy and point out some of the potential promises of multi-wavelength observations in view of the upcoming ground based observational facilities .

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

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?

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.

VERITAS is a major ground-based gamma-ray observatory comprising an array of four 12 meter air Cherenkov telescopes operating at the Fred Lawrence Whipple Observatory near Tucson, Arizona. Data taking has continued from 2007 with a major camera upgrade completed in 2012 resulting in the current sensitivity to very-high-energy (VHE) gamma rays between 85 GeV and 30 TeV. VERITAS has detected 54 sources (half of which have been discoveries) leading to many significant contributions to the field of VHE astronomy. These proceedings highlight some of the more recent VERITAS results from the blazar and galactic observing programs as well as measurements of the cosmic-ray electron spectrum, constraints on dark matter and a follow-up program for astrophysical neutrinos.

Using the results of gamma-ray, millimeter wave and far infrared surveys of the galaxy, one can derive a logically consistent picture of the large scale distribution of galactic gas and cosmic rays, one tied to the overall processes of stellar birth and destruction on a galactic scale. Using the results of the IRAS far-infrared survey of the galaxy, the large scale radial distribution of galactic far-infrared emission were obtained independently for both the Northern and Southern Hemisphere sides of the Galaxy. It was found that the dominant feature in these distributions to be a broad peak coincident with the 5 kpc molecular gas cloud ring. Also found was evidence of spiral arm features. Strong correlations are evident between the large scale galactic distributions of far infrared emission, gamma-ray emission and total CO emission. There is a particularly tight correlation between the distribution of warm molecular clouds and far-infrared emission on a galactic scale.

Pisgah Astronomical Research Institute (PARI) is a not-for-profit public foundation in North Carolina dedicated to providing hands-on educational and research opportunities for a broad cross-section of users in science, technology, engineering and math (STEM) disciplines. In November 2007 a Workshop on a National Plan for Preserving Astronomical Photographic Data (2009ASPC,410,33O, Osborn, W. & Robbins, L) was held at PARI. The result was the establishment of the Astronomical Photographic Data Archive (APDA) at PARI. In late 2013 PARI began ALP (Astronomy Legacy Project). ALP's purpose is to digitize an extensive set of twentieth century photographic astronomical data housed in APDA. Because of the wide range of types of plates, plate dimensions and emulsions found among the 40+ collections, plate digitization will require a versatile set of scanners and digitizing instruments. Internet crowdfunding was used to assist in the purchase of additional digitization equipment that were described at AstroPlate2014 Plate Preservation Workshop (www.astroplate.cz) held in Prague, CZ, March, 2014. Equipment purchased included an Epson Expression 11000XL scanner and two Nikon D800E cameras. These digital instruments will compliment a STScI GAMMA scanner now located in APDA. GAMMA will be adapted to use an electroluminescence light source and a digital camera with a telecentric lens to achieve high-speed high-resolution scanning. The 1μm precision XY stage of GAMMA will allow very precise positioning of the plate stage. Multiple overlapping CCD images of small sections of each plate, tiles, will be combined using a photo-mosaic process similar to one used in Harvard's DASCH project. Implementation of a software pipeline for the creation of a SQL database containing plate images and metadata will be based upon APPLAUSE as described by Tuvikene at AstroPlate2014 (www.astroplate.cz/programs/).

Astronomy Week in Madeira, Portugal

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.

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.

AGILE is a small gamma-ray astronomy satellite mission of the Italian Space Agency dedicated to high-energy astrophysics launched in 2007 April. It provides large sky exposure levels (> or approx. 10{sup 9} cm{sup 2} s per year on the Galactic Plane) with sensitivity peaking at E{approx}400 MeV(and simultaneous X-ray monitoring in the 18-60 keV band) where the bulk of pulsar energy output is typically released. Its {approx}1 {mu}s is absolute time tagging capability makes it perfectly suited for the study of gamma-ray pulsars following up on the CGRO/EGRET heritage. In this paper we summarize the timing results obtained during themore » first year of AGILE observations of the known gamma-ray pulsars Vela, Crab, Geminga and B 1706-4. AGILE collected a large number of gamma-ray photons from EGRET pulsars ({approx}10,000 pulsed counts for Vela) in only few months of observations unveiling new interesting features at sub-millisecond level in the pulsars' high-energy light-curves and paving the way to the discovery of new gamma-ray pulsars.« less

A search of the SAS-2 data for pulsed gamma-ray emission from radio pulsars

NASA Technical Reports Server (NTRS)

Ogelman, H.; Fichtel, C. E.; Kniffen, D. A.; Thompson, D. J.

1976-01-01

Data from the SAS-2 high-energy (above 35 MeV) gamma-ray experiment have been examined for pulsed emission from each of 75 radio pulsars which were viewed by the instrument and which have sufficiently well-defined period and period-derivative information from radio observations to allow for gamma-ray periodicity searches. When gamma-ray arrival times were converted to pulsar phase using the radio reference timing information, two pulsars, PSR 1747-46 and PSR 1818-04, showed positive effects, each with a probability of less than 1 part in 10,000 of being a random fluctuation in the data for that pulsar. These are in addition to PSR 0531+21 and PSR 0833-45, previously reported. The results of this study suggest that gamma-ray astronomy has reached the detection threshold for gamma-ray pulsars and that work in the near future should give important new information on the nature of pulsars.

Most Americans learn about modern science from press reports, while such articles have a bad reputation among scientists. We have performed a study of 403 news articles on three topics (gamma-ray astronomy, supernovae, and Mars) to quantitatively answer the questions 'How accurate are press reports of astronomy?' and 'What fraction of the basic science claims in the press are correct?' We have taken all articles on the topics from five news sources (UPI, NYT, S&T, SN, and 5 newspapers) for one decade (1987-1996). All articles were evaluated for a variety of errors, ranging from the fundamental to the trivial. For 'trivial' errors, S&T and SN were virtually perfect while the various newspapers averaged roughly one trivial error every two articles. For meaningful errors, we found that none of our 403 articles significantly mislead the reader or misrepresented the science. So a major result of our study is that reporters should be rehabilitated into the good graces of astronomers, since they are actually doing a good job. For our second question, we rated each story with the probability that its basic new science claim is correct. We found that the average probability over all stories is 70%, regardless of source, topic, importance, or quoted pundit. How do we reconcile our findings that the press does not make significant errors yet the basic science presented is 30% wrong? The reason is that the nature of news reporting is to present front-line science and the nature of front-line science is that reliable conclusions have not yet been reached. So a second major result of our study is to make the distinction between textbook science (with reliability near 100%) and front-line science which you read in the press (with reliability near 70%).

Launching Astronomy: Standards and STEM Integration (LASSI)

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.

Hipparcos pinpoints an amazing gamma-ray clock

NASA Astrophysics Data System (ADS)

1998-01-01

Following a preliminary report at a symposium on Hipparcos results in Venice in May, the full story of the pinpointing of Geminga is told in a paper to be published in Astronomy and Astrophysics in January 1998. Patrizia Caraveo of the Istituto di Fisica Cosmica in Milan is the lead author, and other astronomers in Milan, Turin, Garching, Copenhagen and Noordwijk contributed to this aspect of the work (see footnote). The result made it possible to to use the observation of gamma-ray pulses to time the rotation of Geminga with extreme accuracy, as described in a paper by John Mattox of Boston University, Jules Halpern of Columbia University, and Patrizia Caraveo. It is due to appear in the Astrophysical Journal in February 1998, and is already accessible on the Internet. Geminga is a unique object: a highly compressed, spinning neutron star which does not emit radio beeps like the well-known pulsars. Yet it is a powerful source of pulsating gamma-rays and X-rays. Geminga is probably the prototype of millions of radio-silent neutron stars in the Milky Way Galaxy, so far unrecognized. "We needed Hipparcos to finish a long and complicated task of tracking down Geminga," Patrizia Caraveo comments. "Never was so faint an object pinpointed so precisely. Now we can say that we have more exact knowledge on the position of Geminga than of any other 'classical' neutron star -- even the famous Crab pulsar." Closing in on Geminga When first observed in a systematic way by COS-B, Geminga's place in the sky was known only to within half a degree -- an uncertainty in position as wide as the Moon. X-ray observations by other satellites narrowed the field and led to the detection of Geminga by visible light, as an extremely faint star. Last year, the same Milan-based Italian team was able to determine the distance of Geminga at 500 light-years, by a succession of observations with the Hubble Space Telescope (see ESA Information Note 04-96). The next task was precisely to situate a

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

Astronomy and Public Policy

NASA Astrophysics Data System (ADS)

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

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.

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

EBL constraints with VERITAS gamma-ray observations

NASA Astrophysics Data System (ADS)

Fernandez Alonso, M.; VERITAS Collaboration

2017-10-01

The extragalactic background light (EBL) contains all the radiation emitted by nuclear and accretion processes since the epoch of recombination. Direct measurements of the EBL in the near-IR to mid-IR waveband are extremely difficult due mainly to the zodiacal light foreground. Instead, gamma-ray astronomy offers the possibility to indirectly set limits to the EBL by studying the effects of gamma-ray absorption in the spectra of detected sources in the very high energy range (VHE: 100 GeV). These effects can be generally seen in the spectra of VHE blazars as a softening (steepening) of the spectrum and/or abrupt changes in the spectral index or breaks. In this work, we use recent VERITAS data of a group of blazars and apply two methods to derive constraints for the EBL spectral properties. We present preliminary results that will be completed with new observations in the near future to enhance the calculated restrictions to the EBL.

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

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.

Apollo-Soyuz pamphlet no. 2: X-rays, gamma-rays. [experimental design

The nature of high energy radiation and its penetration through earth's atmosphere is examined with emphasis on X-rays, gamma rays, and cosmic radiation and the instruments used in their detection. The history of radio astronomy and the capabilities of the Uhuru satellite are summarized. The ASTP soft X-ray experiment (MA-048) designed to study the spectra in the range from 0.1 to 10 keV and survey the background over a large section of the sky is described, as well as the determination of SMC C-1 as an X-ray pulsar. The crystal activation experiment (MA-151) used to measure the radioactive isotopes created by cosmic rays in crystals used for gamma ray detectors is also discussed.

Focal Plane Detectors for the Advanced Gamma-Ray Imaging System (AGIS)

The Advanced Gamma-Ray Imaging System (AGIS) is a concept for the next generation observatory in ground-based very high energy gamma-ray astronomy. It is being designed to achieve a significant improvement in sensitivity compared to current Imaging Air Cherenkov Telescope (IACT) Arrays. One of the main requirements in order that AGIS fulfills this goal will be to achieve higher angular resolution than current IACTs. Simulations show that a substantial improvement in angular resolution may be achieved if the pixel size is reduced to 0.05 deg, i.e. two to three times smaller than for current IACT cameras. Here we present results from testing of alternatives being considered for AGIS, including both silicon photomultipliers (SiPMs) and multi-anode photomultipliers (MAPMTs).

Social Astronomy: Cooperating with Local Community Networks

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.

Muon and Gamma Bundles tracing Up-going Tau Neutrino Astronomy

NASA Astrophysics Data System (ADS)

Fargion, D.; de Santis, M.; de Sanctis Lucentini, P. G.; Grossi, M.

2004-11-01

Up-going and Horizontal Tau Air-Showers, UpTaus and HorTaus, may trace Ultra High Energy Neutrino Tau Earth Skimming at the edge of the horizons. Their secondaries (μ± and γ bundles with e± pair flashes) might trace their nature over UHECR secondaries in horizontal showers. Indeed the atmosphere act as a perfect amplifier as well as a filter for showers: down-ward and horizontal μ bundles may still be originated by far Ultra High Energy Cosmic Rays skimming the terrestrial atmosphere but their rich gamma component will be exponentially suppressed. At large zenith angles after crossing a large slant depth (Xmax > 3 × 103 g cm-2) the number of μ± and secondary γ's (produced by the e± pair from μ decay in flight) is comparable. On the other hand, up-ward muon bundles from UpTaus and HorTaus may arise within a young shower with a larger gamma-muon ratio (˜ 102), leaving its characteristic imprint. We estimate the UpTaus and HorTaus rate from the Earth and we evaluate the consequent event rate of μ±, e± and γ bundles. We show that such events even for minimal GZK neutrino fluxes could be detected by scintillator arrays placed on mountains at 1 -5 km and pointing to the horizon. The required array areas are within tens-hundreds of square meters. An optimal structure is an array of crown-like twin detectors facing the horizons. We argue that such detectors will be able to detect both muonic bundles at a minimal average flux of 10-11 cm-2 s-1 sr-1 and electromagnetic particles (γ, e±) at 3 × 10-9 cm-2 s-1 sr-1, a few times each year, even for the minimal GZK ν flux.

Some aspects of the scientific significance of high energy gamma ray astrophysics

NASA Technical Reports Server (NTRS)

Fichtel, Carl E.

1991-01-01

The attraction of high energy gamma-ray astronomy lies in this radiation relating directly to those processes in astrophysical situations which deviate most from thermo-dynamic equilibrium. Some examples of these phenomena which are known to or expected to emit gamma rays are cosmic rays as they interact in intergalactic space, the high energy particles in the magnetic fields of neutron stars, the death of a black hole, the explosion and residual of a supernova, lumps of Weakly Interacting Massive Particles, energetic solar particles interacting near the sun, and very high energy particles in the extreme conditions associated with active galaxies. Although the intensities are known to be low as seen near the earth, a partially compensating characteristic is that the very penetrating nature of high energy gamma rays increases the probability that they can escape from their origin and reach the solar system.

Primary gamma ray selection in a hybrid timing/imaging Cherenkov array

Postnikov, E. B.; Grinyuk, A. A.; Kuzmichev, L. A.; Sveshnikova, L. G.

2017-06-01

This work is a methodical study on hybrid reconstruction techniques for hybrid imaging/timing Cherenkov observations. This type of hybrid array is to be realized at the gamma-observatory TAIGA intended for very high energy gamma-ray astronomy (> 30 TeV). It aims at combining the cost-effective timing-array technique with imaging telescopes. Hybrid operation of both of these techniques can lead to a relatively cheap way of development of a large area array. The joint approach of gamma event selection was investigated on both types of simulated data: the image parameters from the telescopes, and the shower parameters reconstructed from the timing array. The optimal set of imaging parameters and shower parameters to be combined is revealed. The cosmic ray background suppression factor depending on distance and energy is calculated. The optimal selection technique leads to cosmic ray background suppression of about 2 orders of magnitude on distances up to 450 m for energies greater than 50 TeV.

Editorial: What Use Is Astronomy?

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?

Astronomy Education Challenges in Egypt

NASA Astrophysics Data System (ADS)

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.

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.

Astronomy Teaching Problems in Armenia

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

A Radio Astronomy Curriculum for STARLAB

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.

Development of the Advanced Energetic Pair Telescope (AdEPT) for Medium-Energy Gamma-Ray Astronomy

Hunter, Stanley D.; Bloser, Peter F.; Dion, Michael P.; McConnell, Mark L.; deNolfo, Georgia A.; Son, Seunghee; Ryan, James M.; Stecker, Floyd W.

2011-01-01

Progress in high-energy gamma-ray science has been dramatic since the launch of INTEGRAL, AGILE and FERMI. These instruments, however, are not optimized for observations in the medium-energy (approx.0.3< E(sub gamma)< approx.200 MeV) regime where many astrophysical objects exhibit unique, transitory behavior, such as spectral breaks, bursts, and flares. We outline some of the major science goals of a medium-energy mission. These science goals are best achieved with a combination of two telescopes, a Compton telescope and a pair telescope, optimized to provide significant improvements in angular resolution and sensitivity. In this paper we describe the design of the Advanced Energetic Pair Telescope (AdEPT) based on the Three-Dimensional Track Imager (3-DTI) detector. This technology achieves excellent, medium-energy sensitivity, angular resolution near the kinematic limit, and gamma-ray polarization sensitivity, by high resolution 3-D electron tracking. We describe the performance of a 30x30x30 cm3 prototype of the AdEPT instrument.

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".

Interactive Materials In The Teaching Of Astronomy

NASA Astrophysics Data System (ADS)

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.

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 in Cuba

Alvarez, O.

2008-06-01

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

NASA Astrophysics Data System (ADS)

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.

Gamma Rays from Classical Novae

NASA Technical Reports Server (NTRS)

1997-01-01

NASA at the University of Chicago, provided support for a program of theoretical research into the nature of the thermonuclear outbursts of the classical novae and their implications for gamma ray astronomy. In particular, problems which have been addressed include the role of convection in the earliest stages of nova runaway, the influence of opacity on the characteristics of novae, and the nucleosynthesis expected to accompany nova outbursts on massive Oxygen-Neon-Magnesium (ONeMg) white dwarfs. In the following report, I will identify several critical projects on which considerable progress has been achieved and provide brief summaries of the results obtained:(1) two dimensional simulation of nova runaway; (2) nucleosynthesis of nova modeling; and (3) a quasi-analytic study of nucleosynthesis in ONeMg novae.

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.

Very-high energy gamma-ray astronomy. A 23-year success story in high-energy astroparticle physics

NASA Astrophysics Data System (ADS)

Lorenz, E.; Wagner, R.

2012-08-01

Very-high energy (VHE) gamma quanta contribute only a minuscule fraction - below one per million - to the flux of cosmic rays. Nevertheless, being neutral particles they are currently the best "messengers" of processes from the relativistic/ultra-relativistic Universe because they can be extrapolated back to their origin. The window of VHE gamma rays was opened only in 1989 by the Whipple collaboration, reporting the observation of TeV gamma rays from the Crab nebula. After a slow start, this new field of research is now rapidly expanding with the discovery of more than 150 VHE gamma-ray emitting sources. Progress is intimately related with the steady improvement of detectors and rapidly increasing computing power. We give an overview of the early attempts before and around 1989 and the progress after the pioneering work of the Whipple collaboration. The main focus of this article is on the development of experimental techniques for Earth-bound gamma-ray detectors; consequently, more emphasis is given to those experiments that made an initial breakthrough rather than to the successors which often had and have a similar (sometimes even higher) scientific output as the pioneering experiments. The considered energy threshold is about 30 GeV. At lower energies, observations can presently only be performed with balloon or satellite-borne detectors. Irrespective of the stormy experimental progress, the success story could not have been called a success story without a broad scientific output. Therefore we conclude this article with a summary of the scientific rationales and main results achieved over the last two decades.

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

NASA Astrophysics Data System (ADS)

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.

Exploring the Birth and Evolution of the Universe: How Detectors Have Revolutionized Space Astronomy

NASA Technical Reports Server (NTRS)

Moseley, Samuel H.

2012-01-01

The past century has seen tremendous advances in the capability of instruments used for astronomical imaging and spectroscopy. Capabilities of instruments have expanded in many dimensions; the scale of telescopes has grown tremendously, the wavelengths used for astronomy have grown from visible light to the full electromagnetic spectrum, extending from gamma rays to low frequency radio waves. Additional advances have been enabled by the availability of space facilities, which eliminate the effects of the earths atmosphere and magnetosphere, and allow cooling of instruments to avoid instrumental thermal radiation. Even with all these advances, the increase in capability of detection systems has produced truly revolutionary improvements in capability. Today, I will describe the advances in astronomical detection from the photographic plates of the early 20th century to the giant high efficiency focal planes being developed for modern space and ground based astronomical instrument. I will review the demanding performance requirements set by space astronomy, and show how the detector community has risen to the challenge in producing high performance detectors for the Hubble Space Telescope, the Spitzer Space Telescope, and the James Webb Space Telescope, now under development.

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

Deustua, Susana E.; Ros, R. M.; Garcia, B.

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.

A soft gamma-ray concentrator using thin-film multilayer structures

Bloser, Peter F.; Aliotta, Paul H.; Echt, Olof; Krzanowski, James E.; Legere, Jason S.; McConnell, Mark L.; Shirazi, Farzane; Tsavalas, John G.; Wong, Emily N.; Kippen, R. Marc

2015-09-01

We have begun to investigate the use of thin-film, multilayer structures to form optics capable of concentrating soft gamma rays with energies greater than 100 keV, beyond the reach of current grazing-incidence hard X-ray mirrors. Alternating layers of low- and high-density materials (e.g., polymers and metals) will channel soft gamma-ray photons via total external reflection. A suitable arrangement of bent structures will then concentrate the incident radiation to a point. Gamma-ray optics made in this way offer the potential for soft gamma-ray telescopes with focal lengths of less than 10 m, removing the need for formation flying spacecraft and opening the field up to balloon-borne instruments. Building on initial investigations at Los Alamos National Laboratory, we are investigating whether it is possible to grow such flexible multi-layer structures with the required thicknesses and smoothness using magnetron sputter and pulsed laser deposition techniques. We present the initial results of tests aimed at fabricating such structures by combining magnetron sputtering with either spin coating or pulsed laser deposition, and demonstrating gamma-ray channeling of 122 keV photons in the laboratory. If successful, this technology offers the potential for transformational increases in sensitivity while dramatically improving the system-level performance of future high-energy astronomy missions through reduced mass and complexity.

2008-04-01

Report of the Focal Plane Instrumentation Working Group, AGIS collaboration: The Advanced Gamma-ray Imaging System (AGIS) is a concept for the next generation instrument in ground-based very high energy gamma-ray astronomy. It has the goal of achieving significant improvement in sensitivity over current experiments. One of the main requirements for AGIS will be to achieve higher angular resolution than current imaging atmospheric Cherenkov telescopes (IACTs). Simulations show that a substantial improvement in angular resolution may be achieved if the pixel size is reduced to 0.05 deg, below that of current IACTs. Reducing the cost per channel and improving reliability and modularity are other important considerations. Here we present several alternatives being considered for AGIS, including both silicon photomultipliers (SiPMs) and multi-anode photomultipliers (MAPMTs) and summarize results from feasibility testing by various AGIS photodetector group members.

The IAU Astronomy for Development Programme

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.

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.

Betta, G. F. D.; Manghisoni, M.; Ratti, L.; Re, V.; Speziali, V.; Traversi, G.

2003-12-01

This work is concerned with the effects of /spl gamma/-rays on the static, signal and noise characteristics of JFET-based circuits belonging to a fabrication technology made available by the Istituto per la Ricerca Scientifica e Tecnologica (ITC-IRST), Trento, Italy. Such a process has been tuned with the aim of monolithically integrating the readout electronics on the same highly resistive substrate as multielectrode silicon detectors. The radiation tolerance of some test structures, including single devices and charge sensitive amplifiers, was studied in view of low-noise applications in industrial and medical imaging, X- and /spl gamma/-ray astronomy and high energy physics experiments. This paper intends to fill the gap in the study of gamma radiation effects on JFET devices and circuits belonging to detector-compatible technologies.

Astrostatistics in X-ray Astronomy: Systematics and Calibration

NASA Astrophysics Data System (ADS)

Siemiginowska, Aneta; Kashyap, Vinay; CHASC

2014-01-01

Astrostatistics has been emerging as a new field in X-ray and gamma-ray astronomy, driven by the analysis challenges arising from data collected by high performance missions since the beginning of this century. The development and implementation of new analysis methods and techniques requires a close collaboration between astronomers and statisticians, and requires support from a reliable and continuous funding source. The NASA AISR program was one such, and played a crucial part in our work. Our group (CHASC; http://heawww.harvard.edu/AstroStat/), composed of a mixture of high energy astrophysicists and statisticians, was formed ~15 years ago to address specific issues related to Chandra X-ray Observatory data (Siemiginowska et al. 1997) and was initially fully supported by Chandra. We have developed several statistical methods that have laid the foundation for extensive application of Bayesian methodologies to Poisson data in high-energy astrophysics. I will describe one such project, on dealing with systematic uncertainties (Lee et al. 2011, ApJ ), and present the implementation of the method in Sherpa, the CIAO modeling and fitting application. This algorithm propagates systematic uncertainties in instrumental responses (e.g., ARFs) through the Sherpa spectral modeling chain to obtain realistic error bars on model parameters when the data quality is high. Recent developments include the ability to narrow the space of allowed calibration and obtain better parameter estimates as well as tighter error bars.

2009-01-01

Astronomy was a required subject in the first American secondary level schools, the academies of the 18th century. When these were supplanted a century later by public high schools, astronomy still was often required, subsumed into courses of Natural Philosophy. Reasons given at that time to support astronomy as a part of general education include…

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.

Stoev, A. D.; Bozhurova, E. S.

2006-08-01

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.

Astronomy Research Seminars

Genet, Russell M.

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.

Young Astronomers and Astronomy teaching in Moldavia

NASA Astrophysics Data System (ADS)

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.

The Very Large Array: Pioneering New Directions in Radio Astronomy

NASA Astrophysics Data System (ADS)

McKinnon, Mark

2018-01-01

The Very Large Array (VLA) started science operations in 1980 and was rechristened the Jansky VLA after a major upgrade to its electronics system was completed in 2012. The VLA plays a prominent role in scientific discovery through studies of the Solar System, star and planet formation, galaxy formation, and time domain astronomy. It has attained iconic status as one of the most scientifically productive telescopes on EarthIn 2017, three major initiatives were launched at the VLA with the goal of maintaining its leadership role and impact in radio astronomy in the near and long term future:1. In September, the VLA embarked upon the VLA Sky Survey (VLASS), the highest resolution survey ever undertaken at radio wavelengths. The survey was planned in consultation with the astronomy community and will be used to search for transients, study the polarization properties of extragalactic radio sources, and study highly obscured sources in our Galaxy.2. Detailed planning for a next generation VLA (ngVLA) began in earnest in 2017. The ngVLA will open a new window on the Universe through ultra-sensitive imaging of thermal line and continuum emission down to milliarcsecond resolution, as well as unprecedented broad-band continuum polarimetric imaging of non-thermal processes. A proposal for the instrument will be submitted to the 2020 Decadal Survey.3. A multi-year program to replace the 40+ year old infrastructure at the VLA site was initiated in 2017. The program includes the replacement of the VLA’s electrical infrastructure in 2018, improvements to the VLA rail system, and the replacement of heavy maintenance equipment.The VLA continued to play a major role in discovering and explaining the physics of transient phenomena in 2017, to include fast transients, such as fast radio bursts, and long time scale transients, such as novae, tidal disruption events, and gamma-ray bursts.More thorough descriptions of the VLASS and ngVLA, along with the science that can be done with

Pondering astronomy's perplexingly preposterous propositions

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.

Goldstein, A.; Roberts, O. J.; Connaughton, V.

On 2017 August 17 at 12:41:06 UTC the Fermi Gamma-ray Burst Monitor (GBM) detected and triggered on the short gamma-ray burst (GRB) 170817A. Approximately 1.7 s prior to this GRB, the Laser Interferometer Gravitational-wave Observatory triggered on a binary compact merger candidate associated with the GRB. This is the first unambiguous coincident observation of gravitational waves and electromagnetic radiation from a single astrophysical source and marks the start of gravitational-wave multi-messenger astronomy. We report the GBM observations and analysis of this ordinary short GRB, which extraordinarily confirms that at least some short GRBs are produced by binary compact mergers.

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.

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.

2016-12-01

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: science engagement in the pub

Livermore, Rachael C.; Silverman, Jeffrey Michael

2015-08-01

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

NASA Astrophysics Data System (ADS)

Ferrera, G. A.

1981-09-01

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.

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

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 the gamma-ray Cherenkov telescope at the South Pole

NASA Astrophysics Data System (ADS)

Barbagli, G.; Castellini, G.; Landi, G.; Morse, R.; Tasselli, P. L.; Tilav, S.

1993-05-01

An atmospheric Cherenkov telescope (ACT) designated GASP (Gamma Astronomy at the South Pole) has been installed near the SPASE (South Pole Air Shower Experiment) scintillator array at the South Pole Observing Facility. During the austral summer 1992, it was aimed at objects such as PKS 0537-441 and PSR 1706-44, simultaneously with the Egret detector on the Compton Gamma Ray Observatory (CGRO). Recently observed radio silent quasars that emit gamma rays with enormous intensity may account for the origin of cosmic ray flux at energies that exceed 1016 eV. Other galactic sources like Cygnus X-3 are believed to produce the UHE cosmic gamma flux. In addition to SPASE and GASP, a group of particle detectors (AMANDA, ACA, POOL, MICE) are currently being tested. The above instrumentation will constitute the South Pole Observatory Facility. The members of the GASP collaboration are as follows: Firenze: G. Barbagli G. Castellini, G. Landi, P.L. Tasselli; Purdue: J. Gaidos, F. Loeffler, G. Sembroski; C. Wilson; Smithsonian: K.

Very high energy gamma astronomy at the South Pole

NASA Astrophysics Data System (ADS)

Landi, G.

1991-07-01

The Air Cherenkov Technique (ACT) is a very important tool to extend our present knowledge on very high energy (VHE) gamma emission from compact astrophysical sources. To overcome the intrinsic limitations of this technique, we are testing the possibility of installing an ACT Telescope at the South Pole. This site is ideal for several reasons: The long polar night permits almost continuous ovservation of a source (up to 400 hours per month and 1700 hours per year). The circumpolarity of the sky simplifies data analysis. The region of the sky is particularly rich in candidate sources. To test the effectiveness of the site, we installed a prototype telescope in the austral summer of 1989-1990. The prototype started to operate in May 1990.

The Astronomy Genealogy Project (AstroGen), a project of the Historical Astronomy Division of the American Astronomical Society (AAS), will soon appear on the AAS website. Ultimately, it will list the world's astronomers with their highest degrees, theses for those who wrote them, academic advisors (supervisors), universities, and links to the astronomers or their obituaries, their theses when online, and more. At present the AstroGen team is working on those who earned doctorates with astronomy-related theses. We show what can be learned already, with just ten countries essentially completed.

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).

Europe Unveils 20-Year Plan for Brilliant Future in Astronomy

NASA Astrophysics Data System (ADS)

2008-11-01

for Earth Sciences and Astronomy (INSU) of the CNRS. To build consensus on priorities in a very diverse community, the Science Vision and Roadmap were developed in an open process involving intensive interaction with the community through large open meetings and feedback via e-mail and the web. The result is a plan now backed by astronomers in 28 Member and Associated States of the EU, with over 500 million inhabitants. Over 60 selected experts from across Europe contributed to the construction of the ASTRONET Roadmap, ensuring that European astronomy has the tools to compete successfully in answering the challenges of the Science Vision. They identified and prioritised a set of new facilities to observe the Universe from radio waves to gamma rays, to open up new ways of probing the cosmos, such as gravitational waves, and to advance in the exploration of our Solar System. In the process, they considered all the elements needed by a successful scientific enterprise, from global-scale cooperation on the largest mega-project to the need for training and recruiting skilled young scientists and engineers. One of two top-priority large ground-based projects is ESO's European Extremely Large Telescope. Its 42-metre diameter mirror will make the E-ELT the largest optical/near-infrared telescope in the world -- "the biggest eye on the sky". The science to be done with the E-ELT is extremely exciting and includes studies of exoplanets and discs, galaxy formation and dark energy. ESO Director General Tim de Zeeuw says: "The top ranking of the E-ELT in the Roadmap is a strong endorsement from the European astronomical community. This flagship project will indisputably raise the European scientific, technological and industrial profile". Among other recommendations, the Roadmap considers how to maximise the future scientific impact of existing facilities in a cost-effective manner. It also identifies a need for better access to state-of-the art computing and laboratory facilities

Music and Astronomy Under the Stars - 2009 Update

NASA Astrophysics Data System (ADS)

Lubowich, Donald A.

2010-01-01

Bring telescope to where the people are! Music and Astronomy Under the Stars is a three-year NASA-funded outreach program at parks during and after concerts and family events - a Halloween Spooky Garden Walk. 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

NASA Astrophysics Data System (ADS)

Borgman, Christine; Sands, A.; Wynholds, L. A.

2013-01-01

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

Camera Concepts for the Advanced Gamma-Ray Imaging System (AGIS)

NASA Astrophysics Data System (ADS)

Nepomuk Otte, Adam

2009-05-01

The Advanced Gamma-Ray Imaging System (AGIS) is a concept for the next generation observatory in ground-based very high energy gamma-ray astronomy. Design goals are ten times better sensitivity, higher angular resolution, and a lower energy threshold than existing Cherenkov telescopes. Each telescope is equipped with a camera that detects and records the Cherenkov-light flashes from air showers. The camera is comprised of a pixelated focal plane of blue sensitive and fast (nanosecond) photon detectors that detect the photon signal and convert it into an electrical one. The incorporation of trigger electronics and signal digitization into the camera are under study. Given the size of AGIS, the camera must be reliable, robust, and cost effective. We are investigating several directions that include innovative technologies such as Geiger-mode avalanche-photodiodes as a possible detector and switched capacitor arrays for the digitization.

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

Motivational Differences between MOOC and Undergraduate Astronomy Students

Formanek, Martin; Wenger, Matthew; Buxner, Sanlyn; Impey, Chris David

2018-01-01

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.

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.

Commission 41 was created at the VIIth IAU General Assembly in Zürich in 1948. From an inauspicious start-Otto Neugebauer was appointed the first President in his absence, but proceeded to express his conviction that ``an international organization in the history of astronomy has no positive function. . .my only activity during my term of service consisted in iterated attempts to resign''-the Commission quickly assumed a key role in the international development of the history of astronomy as an academic discipline.

Grote Reber, Radio Astronomy Pioneer, Dies

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

Forman, W.; West, Donald (Technical Monitor)

2001-01-01

We have completed our efforts in support of the Spectrum X Gamma mission under a NASA grant. These activities have included direct support to the mission, developing unifying tools applicable to SXG and other X-ray astronomy missions, and X-ray astronomy research to maintain our understanding of the importance and relevance of SXG to the field. SXG provides: 1) Simultaneous Multiwavelength Capability; 2) Large Field of View High Resolution Imaging Spectroscopy; 3) Sensitive Polarimetry with SXRP (Stellar X-Ray Polarimeter). These capabilities will ensure the fulfillment of the following objectives: understanding the accretion dynamics and the importance of reprocessing, upscattering, and disk viscosity around black holes; studying cluster mergers; spatially resolving cluster cooling flows to detect cooling gas; detecting cool gas in cluster outskirts in absorption; mapping gas in filaments around clusters; finding the 'missing' baryons in the Universe; determining the activity history of the black hole in the Galactic Center of our own central black hole; determining pulsar beam geometry; searching for the Lense-Thirring effect in black hole sources; constraining emission mechanisms and accretion geometry in AGN.

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.

Over the next decade, we will witness the development of a new infrastructure in support of data-intensive scientific research, which includes Astronomy. This new networked environment will offer both challenges and opportunities to our community and has the potential to transform the way data are described, curated and preserved. Based on the lessons learned during the development and management of the ADS, a case is made for adopting the emerging technologies and practices of the Semantic Web to support the way Astronomy research will be conducted. Examples of how small, incremental steps can, in the aggregate, make a significant difference in the provision and repurposing of astronomical data are provided.

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 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

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.

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.

Students Across Texas Celebrate Astronomy Day

2010-08-01

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.

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.

Up to several 10s of TeV, Imaging Air Cherenkov Telescopes (IACTs) have proven to be the instruments of choice for GeV/TeV gamma-ray astronomy due to their good reconstrucion quality and gamma-hadron separation power. However, sensitive observations at and above 100 TeV require very large effective areas (10 km2 and more), which is difficult and expensive to achieve. The alternative to IACTs are shower front sampling arrays (non-imaging technique or timing-arrays) with a large area and a wide field of view. Such experiments provide good core position, energy and angular resolution, but only poor gamma-hadron separation. Combining both experimental approaches, using the strengths of both techniques, could optimize the sensitivity to the highest energies. The TAIGA project plans to combine the non-imaging HiSCORE [8] array with small (∼10m2) imaging telescopes. This paper covers simulation results of this hybrid approach.

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.

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.

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.

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.

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 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.

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.

Hans A. Bethe Prize: Cosmic Collisions Online - Compact Binary Mergers, Gravitational Waves and Gamma-Ray Bursts

Shapiro, Stuart

2017-01-01

Hans A. Bethe elucidated our understanding of the fundamental forces of Nature by exploring and explaining countless phenomena occurring in nuclear laboratories and in stars. With the dawn of gravitational wave astronomy we now can probe compact binary mergers - Nature's cosmic collision experiments - to deepen our understanding, especially where strong-field gravitation is involved. In addition to gravitational waves, some mergers are likely to generate observable electromagnetic and/or neutrino radiation, heralding a new era of multimessenger astronomy. Robust numerical algorithms now allow us to simulate these events in full general relativity on supercomputers. We will describe some recent magnetohydrodynamic simulations that show how binary black hole-neutron star and neutron star-neutron star mergers can launch jets, lending support to the idea that such mergers could be the engines that power short gamma-ray bursts. We will also show how the magnetorotational collapse of very massive stars to spinning black holes immersed in magnetized accretion disks can launch jets as well, reinforcing the belief that such ``collapsars'' are the progenitors of long gamma-ray bursts. Computer-generated movies highlighting some of these simulations will be shown. We gratefully acknowledge support from NSF Grants 1300903 and 1602536 and NASA Grant NNX13AH44G.

Astronomy Outreach for Large, Unique, and Unusual Audiences

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

The Swift Gamma Ray Burst Mission

The Swift mission: scheduled for launch in early 2004: is a multiwavelength observatory for gamma-ray burst (GRB) astronomy. It is the first-of-its-kind autonomous rapid-slewing satellite for transient astronomy and pioneers the way for future rapid-reaction and multiwavelength missions. It will be far more powerful than any previous GRB mission, observing more than 100 bursts per year and performing detailed X-ray and UV/optical afterglow observations spanning timescales from 1 minute to several days after the burst. The objectives are to: 1) determine the origin of GFU3s; 2) classify GRBs and search for new types; 3) study the interaction of the ultra-relativistic outflows of GRBs with their surrounding medium; and 4) use GRBs to study the early universe out to z greater than 10. The mission is being developed by a NASA-led international collaboration. It will carry three instruments: a new-generation wide-field gamma-ray (15-150 keV) detector that will detect bursts, calculate 1-4 arcmin positions: and trigger autonomous spacecraft slews; a narrow-field X-ray telescope that will give 5 arcsec positions and perform spectroscopy in the 0.2 to 10 keV band; and a narrow-field UV/optical telescope that will operate in the 170-600 nm band and provide 0.3 arcsec positions and optical finding charts. Redshift determinations will be made for most bursts. In addition to the primary GRB science, the mission will perform a hard X-ray survey to a sensitivity of approx. 1 mCrab (approx. 2 x l0(exp -11) erg/sq cm s in the 15-150 keV band), more than an order of magnitude better than HEAO A-4. A flexible data and operations system will allow rapid follow-up observations of all types of high-energy transients. with rapid data downlink and uplink available through the NASA TDRSS system. Swift transient data will be rapidly distributed to the astronomical community and all interested observers are encouraged to participate in follow-up measurements. A Guest Investigator program

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

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.

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.

The Advanced Gamma-ray Imaging System (AGIS): Telescope Mechanical Designs

The concept of a future ground-based gamma-ray observatory, AGIS, in the energy range 40 GeV-100 TeV is based on an array of sim 100 imaging atmospheric Cherenkov telescopes (IACTs). The anticipated improvements of AGIS sensitivity, angular resolution and reliability of operation impose demanding technological and cost requirements on the design of IACTs. The relatively inexpensive Davies-Cotton telescope design has been used in ground-based gamma-ray astronomy for almost fifty years and is an excellent option. We are also exploring alternative designs and in this submission we focus on the recent mechanical design of a two-mirror telescope with a Schwarzschild-Couder (SC) optical system. The mechanical structure provides support points for mirrors and camera. The design was driven by the requirement of minimizing the deflections of the mirror support structures. The structure is also designed to be able to slew in elevation and azimuth at 10 degrees/sec.

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.

Our Attempts in Astronomy

NASA Astrophysics Data System (ADS)

Vanichai, Yupa

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.
