Galactic Center Chandra X-Ray Source Near-IR Counterparts

This table contains a catalog of 5184 candidate infrared counterparts to X-ray sources detected toward the Galactic center. The X-ray sample contains 9017 point sources detected in this region by the Chandra X-ray Observatory during the past decade, including data from a recent deep survey of the central 2 degrees x 0.8 degrees of the Galactic plane. A total of 6760 of these sources have hard X-ray colors, and the majority of them lie near the Galactic center, while most of the remaining 2257 soft X-ray sources lie in the foreground. The authors have cross-correlated the X-ray source positions with the 2MASS and SIRIUS near-infrared catalogs, which collectively contain stars with a 10-sigma limiting flux of K&lt;sub&gt;s&lt;/sub&gt; &lt;= 15.6 mag. In order to distinguish absorbed infrared sources near the Galactic center from those in the foreground, they defined red and blue sources as those which have H - K&lt;sub&gt;s&lt;/sub&gt; &gt;= 0.9 and &lt; 0.9 mag, respectively. The authors find that 5.8% =/- 1.5% (2 sigma) of the hard X-ray sources have real infrared counterparts, of which 228 +/- 99 are red and 166 +/- 27 are blue. The red counterparts are probably comprised of Wolf-Rayet and O stars, high-mass X-ray binaries, and symbiotic binaries located near the Galactic center. Foreground X-ray binaries suffering intrinsic X-ray absorption could be included in the sample of blue infrared counterparts to hard X-ray sources. The authors also find that 39.4% +/- 1.0% of the soft X-ray sources have blue infrared counterparts; most of these are probably coronally active dwarfs in the foreground. There is a noteworthy collection of ~20 red counterparts to hard X-ray sources near the Sagittarius B H II region, which are probably massive binaries that have formed within the last several Myr. For each of the infrared matches to X-ray sources in their catalog, the authors derived the probability that the association is real, based on the source properties and the results of the cross-correlation analysis. These data are included in this catalog and will serve spectroscopic surveys to identify infrared counterparts to X-ray sources near the Galactic center. This table was created by the HEASARC in October 2009 based on the electronic version of Table 3 from the reference paper which was obtained from the Astrophysical Journal web site.

TeV Gamma-Ray Source Catalog

TeVCat (&lt;a href="http://tevcat.org/"&gt;http://tevcat.org/&lt;/a&gt;) is an online, interactive catalog for very-high-energy (VHE: energies, E &gt;~ 50 GeV) gamma-ray astronomy. As VHE astronomy continues to grow, the usefulness of a one-stop clearing house for information on new sources is increasingly evident. TeVCat is intended to be such a resource. With sky maps, scientific information, visibility plotters and linked references available at the website, it will help the wider gamma-ray community stay up-to-date and informed on this exciting and rapidly developing field. This HEASARC database table provides the TeVCat list of VHE sources as well as links to the TeV source resource pages on the TeVCat website. The catalog and &lt;a href="http://tevcat.org/"&gt;the website at the University of Chicago&lt;/a&gt; are maintained by Scott Wakely and Deirdre Horan. This table was first ingested by the HEASARC in July 2017 based on the catalog of VHE gamma-ray sources available at &lt;a href="http://tevcat.org/"&gt;http://tevcat.org/&lt;/a&gt;. It is updated automatically within a few days of the catalog being updated on the University of Chicago website. This is a service provided by NASA HEASARC .

VG2 JUP PLASMA DERIVED ELECTRON MOMENTS96.0 SEC V1.1

This data set contains derived values    of the electron density and moment temperature at Jupiter during the    Voyager 2 encounter in the PLS voltage range (10-5950 eV/q). Adjacent low    and high energy electron measurements are combined to form a composite    spectra which is used for the moment calculation. These assume isotropic    distributions and correct for positive spacecraft charge when applicable    and interpolate electron spectra below the 10 eV instrument threshold    before performing the integration over velocity. Data format: column 1 is    time (yyyy-mm-ddThh:mm:ss.sssZ), column 2 is the moment density in cm^-3,    column 3 the temperature in eV. Each row has format (a24, 2(1x,1pe9.2)).    Values of -9.99e+10 indicate that the parameter could not be obtained from    the data using the standard analysis technique. Additional information    about this data set and the instrument which produced it can be found    elsewhere in this catalog.

ROSAT All-Sky Survey Bright Source Catalog/Catalog of Principal Galaxies Matches

In a correlation study of the ROSAT All-Sky Survey Bright Source Catalog (RASS-BSC, &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/XI/10"&gt;CDS Cat. &lt;XI/10&gt;&lt;/a&gt;, the HEASARC table RASSBSC) with the Catalogue of Principal Galaxies (PGC, &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/VII/119"&gt;CDS Cat. &lt;VII/119&gt;&lt;/a&gt;, the HEASARC table PGC2003), 904 X-ray sources were found that possess possible extragalactic counterparts within a search radius of 100 arcseconds. A visual screening process was applied to classify the reliability of the correlations. 547 correlations have been quoted as reliable identifications. From these, 349 sources are known to be active galaxies. Although for the other sources no hints for activity were found in the literature, 69% of those for which we have distances show X-ray luminosities exceeding those of normal galaxies, a clear sign that these galaxies also own hitherto unreported X-ray active components. Some objects are located inside or in the direction of a known group or cluster of galaxies. Their X-ray flux may therefore be in part affected by hot gas emission. In the paper, luminosity and log N-log S distributions are used to characterize different subsamples. Nuclei that are both optically and X-ray active are found predominantly in spirals. Two special source samples are defined, one with candidates for X-ray emission from hitherto unknown groups or clusters of galaxies, and one with high X-ray luminosity sources, that are likely candidates to possess hitherto unreported active galactic nuclei. Besides a compilation of X-ray and optical parameters, X-ray overlays on optical images for all the objects are also supplied as part of this work. This table contains 1124 optical galaxy entries for the 904 relevant X-ray candidates/counterparts from the RASS. Besides a compilation of X-ray and optical parameters for each source, the results of an identification screening are also given. The 904 optical images with X-ray overlay contours (xID_nnn.ps.gz) used in the screening process are added for each user&#39;s own judgement of the reliability of the associations. This table was created by the HEASARC in March 2012 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/378/30"&gt;CDS catalog J/A+A/378/30&lt;/a&gt; file table1.dat, the list of PGC galaxies identified as possible counterparts to RASS Bright Source Catalog X-ray sources.

Taurus Molecular Cloud XMM-Newton X-Ray Source Catalog

The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus Molecular Cloud, using the XMM-Newton X-ray observatory to study the thermal structure, variability, and long-term evolution of hot plasma, to investigate the magnetic dynamo, and to search for new potential members of the association. The authors present overall correlations with fundamental stellar parameters that were derived from the previous literature. The present overview paper introduces the project and provides the basic results from the X-ray analysis of all sources detected in the XEST survey. Comprehensive tables in the published paper summarize the stellar properties of all the targets surveyed. The survey goes deeper than previous X-ray surveys of Taurus by about an order of magnitude and for the first time systematically accesses very faint and strongly absorbed TMC objects. The authors find a detection rate of 85% and 98% for classical and weak-line T Tauri stars (CTTS and WTTS), respectively, and identify about half of the surveyed protostars and brown dwarfs. Overall, 136 out of 169 surveyed stellar systems were detected. The authors describe an X-ray luminosity vs. mass correlation, discuss the distribution of X-ray-to-bolometric luminosity ratios, and show evidence for lower X-ray luminosities in CTTS compared to WTTS. The complete catalog of all X-ray sources (stellar and non-stellar) detected in the 28 XEST fields is presented in this table. The catalog provides X-ray coordinates, their uncertainties, X-ray count rates and their uncertainties, and X-ray hardness ratios for 2347 detected X-ray sources. If two XEST fields overlap, the same sources may have been identified twice, with different XEST IDs assigned, notice. This table was created by the HEASARC in July 2007 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/468/353"&gt;CDS Catalog J/A+A/468/353&lt;/a&gt; file table14.dat.

The ATLAS All-Sky Stellar Reference Catalog ConeSearch

All MAST catalog holdings are available via Cone Search endpoints. \nThis service provides access to the ATLAS All-Sky Stellar Reference Catalog.\n\nThe Asteroid Terrestrial-impact Last Alert System (ATLAS) observes most of the sky every night in search of dangerous asteroids. Its data are also used to search for photometric variability, where sensitivity to variability is limited by photometric accuracy. Since each exposure spans 7.6 deg corner to corner, variations in atmospheric transparency in excess of 0.01 mag are common, and 0.01 mag photometry cannot be achieved by using a constant flat field calibration image. We therefore have assembled an all-sky reference catalog of approximately one billion stars to m~19 from a variety of sources to calibrate each exposure's astrometry and photometry. Gaia DR2 is the source of astrometry for this ATLAS Refcat2. The sources of g, r, i, z photometry include Pan-STARRS DR1, the ATLAS Pathfinder photometry project, ATLAS re-flattened APASS data, SkyMapper DR1, APASS DR9, the Tycho-2 catalog, and the Yale Bright Star Catalog. We have attempted to make this catalog at least 99% complete to m less than 19, including the brightest stars in the sky. We believe that the systematic errors are no larger than 5 millimag RMS, although errors are as large as 20 millimag in small patches near the galactic plane. \n\nAll available missions are listed at http://archive.stsci.edu/vo/mast_services.html.
