In the past few decades there has been growing realization that the Cepheid Near-Infrared (NIR) Period-Luminosity (PL) relation is superior to the Optical PL relation, however, there has been little to no new NIR data gathered on Galactic Cepheids despite the growing popularity and availability of NIR detectors. ...

Quadrupole magnets and other beam transport elements located near the high-luminosity intersection regions at POPAE are discussed with respect to keeping all potentially interesting regions of phase-space accessible to experimental investigation. A possib...

Supernova (SN) 2006gy was a hydrogen-rich core-collapse SN that remains one of the most luminous optical SNe ever observed. The total energy budget (>2 x 10{sup 51} erg radiated in the optical alone) poses many challenges for standard SN theory. We present new ground-based near-infrared (NIR) observations of SN 2006gy, as well as a single epoch of Hubble Space Telescope ...

After our report (ATel #3347) of recent NIR activity in B21144+40, a z-1.088 QSO also known as CGRaBS J1146+3958, we have follow the luminosity evolution of this object, and we report now a fast increase in flux in a eight day period. On JD2455693.717975, we determined its flux to correspond to H = 13.439 � 0.05, while on JD2455701.794745, the flux was ...

New NIR and FIR maps and J = 1-0 CO spectroscopy of the Magellanic irregular galaxy NGC 4449 are presented. The brighter 150-micron emission is concentrated along the central visual ridge of the galaxy, although there is lower intensity extended emission throughout the visible extent of the object. The maximum FIR emission is coincident, within the uncertainties, with the ...

Understanding the light curves of Type Ia Supernovae (SNe Ia) is essential to their use as standard candles in cosmological studies. Recent observations of SNe Ia have shown brighter than expected NIR emission at very late phases resulting in brighter than expected bolometric luminosity at that epoch. Also, some observations showed that the optical bands ...

We present the near-infrared luminosity and stellar mass functions (SMFs) of galaxies in the core of the Shapley supercluster at z = 0.048, based on new K-band observations carried out at the United Kingdom Infrared Telescope with the Wide Field Infrared Camera in conjunction with B- and R-band photometry from the Shapley Optical Survey, and including a subsample (~650 ...

(abridged) We found in previous studies that standard Simple Stellar Population (SSP) models are unable to describe or explain the colours of Galactic open clusters both in the visible and in the NIR spectral range. (...) We construct a numerical SSP-model, with an underlying Salpeter IMF, valid within an upper $m_u$ and lower $m_l$ stellar mass range, and with total masses ...

We propose a new method to explore the candidate super-Eddington active galactic nuclei (AGNs). We examine the properties of infrared (IR) emission from the inner edge of the dusty torus in AGNs, which are powered by super- or sub-Eddington accretion flows around black holes, by considering the dependence of the polar angle on the radiation flux of accretion flows. We find that for super-Eddington ...

Context: The luminosity-metallicity relation is one of the fundamental constraints in the study of galaxy evolution; yet none of the relations available today has been universally accepted by the community. Aims: The present work is a first step to collect homogeneous abundances and near-infrared (NIR) luminosities for a sample of ...

We have constructed a comprehensive statistical model for Type Ia supernova (SN Ia) light curves spanning optical through near-infrared (NIR) data. A hierarchical framework coherently models multiple random and uncertain effects, including intrinsic supernova (SN) light curve covariances, dust extinction and reddening, and distances. An improved BAYESN Markov Chain Monte Carlo ...

In this paper, we have searched for the Two Micron All Sky Survey (2MASS) counterparts of 1434 BL Lacs. Eight hundred and thirty-three of 1434 BL Lacs (�58%) have spatially coincident 2MASS counterparts. Fermi-detected BL Lacs (FBLs) have a much higher 2MASS detection rate than non-Fermi-detected BL Lacs (non-FBLs) (�95% vs 49%). We compare the near-infrared (NIR) apparent ...

We present the results from a near-infrared (NIR) synoptic survey of Northern Galactic Cepheid Variable Stars undertaken at the University of Wyoming's 0.6m telescope at Red Buttes Observatory (RBO). The observations were carried out using BIRCAM (Buttes InfraRed CAMera), a NIR camera developed for use at RBO. The sample consists of 134 fundamental mode ...

We describe a near-infrared (NIR) synoptic survey of Northern Galactic Cepheid Variable Stars undertaken at the University of Wyoming's 0.6m telescope at Red Buttes Observatory (RBO). The observations were carried out using BIRCAM (Buttes InfraRed CAMera), a NIR camera developed for use at RBO. The sample consists of 134 fundamental mode cepheids ranging ...

The expansion of the world economy has enabled easy access to suppliers of optical components and systems throughout the world. Unfortunately, all manufacturers do not adhere to the same quality standards, so the need for accurate and cost effective inspection has never been greater. To address this growing demand, an economical platform for evaluating the performance of ...

Aims: We determine the integrated magnitudes and colours of 650 clusters in optical (BV) and the near-infrared (JHK_s) passbands and construct the luminosity functions of the Galactic open clusters in these passbands. Methods: The magnitudes are based on accurate and uniform cluster membership parameters derived from the ASCC-2.5 catalogue and were computed by adding the ...

Quantification of microbial respiration rates in subsurface environments is complicated by difficult access to samples, impervious aquifer materials, and a lack of information about groundwater transport processes. Here, Quantitative Reverse Transcriptase Polymerase Chain Reaction (Q-RT-PCR) is investigated as a novel method of directly quantifying biological denitrification ...

Statistically complete samples of inner-pseudo-, inner-, and outer-ringed galaxies can be extracted from the Catalog of Southern Ringed Galaxies. Redshifts and near-infrared (NIR) photometric data are available for the samples, allowing the derivation of the statistical correlations between the total NIR luminosities (L ...

From the literature, we construct a sample of 25 Seyfert 2 galaxies (S2s) with a broad line region (BLR) detected in near infrared (NIR) spectroscopy and 29 with NIR BLRs which were not detected. We find no significant difference between the nuclei luminosity (extinction-corrected [OIII] 5007) and infrared color f60/f25 between the two ...

The impressive deep and panoramic Chandra images of the Galactic center region uncovered thousands of low-luminosity compact X-ray binaries. We are now extending these studies in the latitude direction, i.e. centered on the Galactic center and perpendicular to the plane The Bulge Latitude Survey is our multi-wavelength (X-ray/optical/near-infrared) effort to map out, for the ...

Context. We found in previous studies that standard simple stellar population (SSP) models are unable to describe or explain the colours of Galactic open clusters both in the visible and in the near-infrared (NIR) spectral range. The reason for this disagreement is the continuous nature of the stellar initial mass function (IMF) in clusters, which is the underlying assumption ...

We set out to expand the number of brown dwarfs with calculated luminosities and bolometric corrections. We chose our sample by collecting published near infrared spectra of brown dwarfs from the Spex Prism Library. The sample is predominantly L and T type dwarfs, although some M dwarfs have been included. These spectral energy distributions were extended to optical ...

Reanalysis of the NIR spectrum of the star-formation object WL 16 indicates that the observed infrared CO emission has a high optical depth, creating a CO emission continuum feature. A new extinction value A(v) = 40 places the Brackett gamma emission within the normal range for low-luminosity line excess sources. The observations are consistent with a ...

The X-ray source IGR J16318-4848 was the first source discovered by INTEGRAL on 2003, January 29. We carried out optical and near-infrared (NIR) observations at the European Southern Observatory (ESO La Silla) in the course of a Target of Opportunity (ToO) programme. We discovered the optical counterpart and confirmed an already proposed NIR candidate. ...

We studied the geometry of the inner (AU-scale) circumstellar environment around the Herbig Be star MWC 147. Combining, for the first time, near- (NIR, K band) and mid-infrared (MIR, N band) spectro-interferometry on a Herbig star, our VLTI/MIDI and AMBER data constrain not only the geometry of the brightness distribution, but also the radial temperature distribution in the ...

We combine data from the Millennium Galaxy Catalogue, Sloan Digital Sky Survey and UKIRT Infrared Deep Sky Survey Large Area Survey to produce ugrizYJHK luminosity functions and densities from within a common, low-redshift volume (z < 0.1, ~ 71000h-31 Mpc3 for L* systems) with 100 per cent spectroscopic completeness. In the optical the fitted Schechter functions are ...

The Energetic X-ray Imaging Survey Telescope (EXIST) is a proposed hard X-ray imaging all-sky deep survey mission recommended by the Report of the 2001 Decadal Survey. It is a strong candidate to be the Black Hole Finder Probe, one of the three "Einstein Probes" in the Beyond Einstein Program. In its new more evolved form, the EXIST mission now includes a simplified, but more sensitive, very large ...

XSS J12270-4859 (J12270) is an enigmatic source of unknown nature. Previous studies revealed that the source has unusual X-ray temporal characteristics, including repetitive short-term flares followed by spectral hardening, non-periodic dips, and dichotomy in activity; i.e. intervals filled with flares and those without. Together with a power-law X-ray spectrum, it is suggested to be a low-mass ...

What types of stars dominate the luminosity of the newly discovered Galactic star cluster Mercer 23 (Mercer et al. 2005) found in GLIMPSE data, and what can this reveal about its past and future? We started a program to obtain NIR spectroscopy of the brightest members of the new Mercer et al. clusters in the Northern GLIMPSE survey segment and to augment ...

A review is given of the physics accessible at a very high energy hadron-hadron collider. Emphasis is placed on the reliability of the predicted rates, and upon the energy and luminosity required to explore new physics options. 38 refs., 19 figs.

We fitted the optical to mid-infrared (MIR) spectral energy distributions of ~15,000 type-I, 0.75 < z < 2, active galactic nuclei (AGNs) in an attempt to constrain the properties of the physical component responsible for the rest-frame near-infrared (NIR) emission. We combine optical spectra from the Sloan Digital Sky Survey and MIR photometry from the preliminary data ...

A brain-computer interface (BCI) is a device that allows a user to communicate with external devices through thought processes alone. A novel signal acquisition tool for BCIs is near-infrared spectroscopy (NIRS), an optical technique to measure localized cortical brain activity. The benefits of using this non-invasive modality are safety, portability and ...

As a result of a systematic NIR H-band (1.65 ^mum) imaging survey of normal galaxies in the local universe that includes objects both in the Virgo cluster and in the ``Great Wall'' (including A1367, A1656 as well as the ``isolated'' population in the bridge between the two clusters), we are able to measure in a highly homogeneous way photometric and structural properties for a ...

Due to sampling restrictions in the analysis of cultural heritage materials, non-destructive approaches are intensively sought for. While NIR spectrometry has rarely been used for this purpose due to the complexity of the spectra, chemometric methods can be used to extract the necessary information. For the purpose of determination of mechanical properties of historical paper, ...

The optical/near-infrared (OIR) region of the spectra of low-mass X-ray binaries (XBs) appears to lie at the intersection of a variety of different emission processes. In this paper we present quasi-simultaneous OIR-X-ray observations of 33 XBs in an attempt to estimate the contributions of various emission processes in these sources, as a function of X-ray state and ...

For my Astronomy Ph.D. thesis at Harvard University, I used the PAIRITEL 1.3m robotic telescope at the Fred Lawrence Whipple Observatory on Mt. Hopkins, Arizona to observe Near-Infrared (NIR) JHKs band light curves of over 100 Type Ia Supernovae (SN Ia) in nearby galaxies, compiling a data set that will more than quintuple the number of NIR SN Ia light ...

We present new optical and near-infrared (NIR) photometry and spectroscopy of the Type IIP supernova (SN), SN 2004et. In combination with already published data, this provides one of the most complete studies of optical and NIR data for any Type IIP SN from just after explosion to +500d. The contribution of the NIR flux to the ...

Aims: We provide accurate estimates of distances, radii, and iron abundances of four metal-rich Cepheids, namely V340 Ara, UZ Sct, AV Sgr, and VY Sgr. The main aim of this investigation is to constrain their pulsation properties and their location across the Galactic inner disk. Methods: We adopted new accurate NIR (J,H,K) light curves and new radial velocity measurements for ...

We present sensitive near-infrared (NIR) VLT ISAAC spectroscopic observations of the z = 6.08 quasar SDSS J030331.40-001912.9. This quasi-stellar object (QSO) is more than a magnitude fainter than other QSOs at z {approx} 6 for which NIR spectroscopy has been obtained to date and is therefore presumably more representative of the QSO population at the end ...

Investigation of the diversity of nirK and nirS in denitrifying bacteria revealed that salinity decreased the diversity in a nitrate-containing saline wastewater treatment system. The predominant nirS clone was related to nirS derived from marine bacteria, and the predominant nirK clone was ...
