Point Sources from a Spitzer/IRAC Survey of the Galactic Center

Spitzer/IRAC observations of the central 2.0 deg by 1.4 deg (~ 280 pc by 200 pc) of the Galaxy were obtained at 3.6-8.0 microns in Cycle 1 (GO 3677, PI: Stolovy). These data represent the highest spatial resolution (~2 arcsec) and sensitivity uniform large-scale map made to date of the Galactic Center at mid-infrared wavelengths.\n\nA point source catalog of 1,065,565 objects was obtained. The catalog includes magnitudes for the point sources at 3.6, 4.5, 5.8, and 8.0 microns, as well as JHK photometry from 2MASS. The point source catalog is confusion limited with average limits of 12.4, 12.1, 11.7, and 11.2 magnitudes for [3.6], [4.5], [5.8], and [8.0], respectively. The confusion limits are spatially variable because of stellar surface density, background surface brightness level, and extinction variations across the survey region. More details about the point source catalog can be found at Ramirez et al. 2008.

ROSATPSPCCatalogofLMCX-RaySources(Haberl&Pietsch)

More than 200 ROSAT PSPC observations performed between 1990 and 1994 in a 10 by 10 degree field centered on the Large Magellanic Cloud (LMC) have been analyzed on order to derive a catalogue of X-ray sources. The list contains 758 sources together with their X-ray properties. From cross-correlations of the PSPC catalogue with the SIMBAD data base and literature searches likely identifications are given in the paper from which this catalogue was derived (Haberl &amp; Pietsch 1999, A&amp;AS, 139, 277: Table 10) for 144 of these X-ray sources based on positional coincidence, but also taking into account X-ray properties like hardness ratios and source extent. Forty-six known sources are associated with supernova remnants and candidates in the LMC (SNRs: Haberl &amp; Pietsch 1999, A&amp;AS, 139, 277: Table 6), most of them already detected by previous X-ray missions. The number of known X-ray binaries in the LMC has increased to 17, and of supersoft sources to 9. The remaining ~50% of the identified sources comprise mainly foreground stars (up to 57) and background extragalactic objects (up to 15). This database was created at the HEASARC in June 2000 based on the ADC/&lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+AS/139/277"&gt;CDS Catalog J/A+AS/139/277&lt;/a&gt;, and is derived from Table 1 of the reference.

RCW 38 Chandra X-Ray Point Source Catalog 2

This table contains some of the results from a study of the structure of the high-mass star-forming region RCW 38 and the spatial distribution of its young stellar population. Spitzer Infrared Array Camera (IRAC) photometry (3-8 micron) is combined with Two Micron All Sky Survey (2MASS) near-IR data to identify young stellar objects (YSOs) by IR-excess emission from their circumstellar material. Chandra X-ray data are used to identify class III pre-main-sequence stars lacking circumstellar material. The authors identify 624 YSOs: 23 class 0/I and 90 flat spectrum (FS) protostars, 437 class II stars, and 74 class III stars. They also identify 29 (27 new) O star candidates over the IRAC field. Seventy-two stars exhibit IR-variability, including 7 class 0/I and 12 flat spectrum YSOs. A further 177 tentative candidates are identified by their location in the IRAC [3.6] versus [3.6]-[5.8] color-magnitude diagram. The authors find strong evidence of subclustering in the region. Three subclusters were identified surrounding the central cluster, with massive and variable stars in each subcluster. The central region shows evidence of distinct spatial distributions of the protostars and pre-main-sequence stars. A previously detected IR cluster, DB2001_Obj36, has been established as a subcluster of RCW 38. This suggests that star formation in RCW 38 occurs over a more extended area than previously thought. The gas-to-dust ratio is examined using the X-ray derived hydrogen column density, NH and the K-band extinction, and found to be consistent with the diffuse interstellar medium, in contrast with Serpens and NGC 1333. The authors posit that the high photoionizing flux of massive stars in RCW 38 affects the agglomeration of the dust grains. This table contains the list of 536 X-ray sources found in the Chandra data using a three-pass method with the CIAO 3.4 Wavdetect tool. This table was created by the HEASARC in January 2012 based on an electronic version of Table 2 from the reference paper which was obtained from the ApJ website. Some of the values for the name parameter in the HEASARC&#39;s implementation of this table were corrected in April 2018. This is a service provided by NASA HEASARC .

VLA Lockman Hole 1400-MHz Radio Source Catalog

In the run-up to routine observations with the upcoming generation of radio facilities, the nature of the sub-mJy radio population has been hotly debated. In this paper, the authors describe multi-frequency data designed to probe the emission mechanism that dominates in these faint radio sources. Their analysis is based on observations of the Lockman Hole (LH) using the Giant Metrewave Radio Telescope (GMRT) near Pune, India - the deepest 610-MHz imaging yet reported - together with 1.4-GHz imaging from the Very Large Array (VLA), which are well matched in resolution and sensitivity to the GMRT data: sigma&lt;sub&gt;610MHz&lt;/sub&gt; ~ 15 &micro;Jy/beam (&micro;Jy/beam), sigma}&lt;sub&gt;1.4GHz&lt;/sub&gt; ~ 6 &micro;Jy/beam, and full width at half-maximum (FWHM) ~ 5 arcseconds. The GMRT and VLA data are cross-matched to obtain the radio spectral indices for the faint radio emitters. During six 12-hr sessions in 2006 February and July, the authors obtained data at 610 MHz for three pointings (FWHM ~ 43 arcminutes) in the LH (see Table 1 of the reference paper for full details), separated by 11 arcminutes (the LOCKMAN-E, LOCK-3 and LHEX-4 fields), typically with 28 of the 30 antennas that comprise the GMRT. The total integration time in each field, after overheads, was 16 hr. The final image had a noise level in the central 100 arcmin&lt;sup&gt;2&lt;/sup&gt; of 14.7 &micro;Jy/beam, the deepest map reported at 610 MHz as of the date of publication, despite the modest integration time. New and archival data were obtained at the same three positions using the National Radio Astronomy Observatory&#39;s VLA, largely in its B configuration. This table contains 1450 sources found in the LH field at 1400 MHz by the VLA. For 17 of the sources which have multiple components, the 29 individual components are listed as well. Thus, the final table contains 1479 (1450 + 29) entries. Source extraction was based on criteria of peak brightness &gt; 5 times the local rms and integrated flux density &gt; 3 times the local rms. This table was created by the HEASARC in February 2012 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/397/281"&gt;CDS Catalog J/MNRAS/397/281&lt;/a&gt; file table4.dat.

Australia Telescope Low-Brightness Survey Source Catalog

The Australia Telescope Low-brightness Survey (ATLBS) regions have been mosaic imaged at a radio frequency of 1.4 GHz with 6 arcseconds angular resolution and 72 microJansky per beam (&micro;Jy/beam) rms noise. The images (centered at RA 00&lt;sup&gt;h&lt;/sup&gt; 35&lt;sup&gt;m&lt;/sup&gt; 00&lt;sup&gt;s&lt;/sup&gt;, Dec -67&lt;sup&gt;o&lt;/sup&gt; 00&#39; 00&quot; and RA 00&lt;sup&gt;h&lt;/sup&gt; 59&lt;sup&gt;m&lt;/sup&gt; 17&lt;sup&gt;s&lt;/sup&gt;, Dec -67&lt;sup&gt;o&lt;/sup&gt; 00&#39; 00&quot;, J2000 epoch) cover 8.42 deg&lt;sup&gt;2&lt;/sup&gt; sky area and have no artifacts or imaging errors above the image thermal noise. Multi-resolution radio and optical r-band images (made using the 4 m CTIO Blanco telescope) were used to recognize multi-component sources and prepare a source list of 1366 1.4-GHZ sources; the detection threshold was 0.38 mJy in a low-resolution radio image made with beam FWHM of 50 arcseconds. Radio source counts in the flux density range 0.4-8.7 mJy are estimated, with corrections applied for noise bias, effective area correction, and resolution bias. The resolution bias is mitigated using low-resolution radio images, while effects of source confusion are removed by using high-resolution images for identifying blended sources. Below 1 mJy the ATLBS counts are systematically lower than the previous estimates. Showing no evidence for an upturn down to 0.4 mJy, they do not require any changes in the radio source population down to the limit of the survey. The work suggests that automated image analysis for counts may be dependent on the ability of the imaging to reproduce connecting emission with low surface brightness and on the ability of the algorithm to recognize sources, which may require that source finding algorithms effectively work with multi-resolution and multi-wavelength data. The work underscores the importance of using source lists - as opposed to component lists - and correcting for the noise bias in order to precisely estimate counts close to the image noise and determine the upturn at sub-mJy flux density. This table was created by the HEASARC in April 2013 based on an electronic version of Table 2 from the reference paper that was obtained from the ApJ web site..

AKARI NEP WSRT 20-cm Source Catalog

The Westerbork Radio Synthesis Telescope (WSRT) has been used in 2004 to make a deep radio survey of an ~1.7 degree&lt;sup&gt;2&lt;/sup&gt; field coinciding with the AKARI north ecliptic pole (NEP) deep field. The WSRT survey consisted of 10 pointings, mosaiced with enough overlap to maintain a similar sensitivity across the central region that reached as low as 21 microJanskies/beam (&micro;Jy/beam) at 1.4 GHz. The observations, data reduction and source count analysis are presented in the reference paper, along with a description of the overall scientific objectives. A catalog containing 462 sources detected with a resolution of 17.0 arcsecs by 15.5 arcsecs is presented. The differential source counts calculated from the WSRT data have been compared with those from the shallow VLA-NEP survey of Kollgaard et al. (1994, ApJS, 93, 145), and show a pronounced excess for sources fainter than ~1 mJy, consistent with the presence of a population of star-forming galaxies at sub-mJy flux levels. The AKARI NEP deep field is the focus of a major observing campaign conducted across the entire spectral region. The combination of these data sets, along with the deep nature of the radio observations will allow unique studies of a large range of topics including the redshift evolution of the luminosity function of radio sources, the clustering environment of radio galaxies, the nature of obscured radio-loud active galactic nuclei, and the radio/far-infrared correlation for distant galaxies. This catalog provides the basic data set for a future series of paper dealing with source identifications, morphologies, and the associated properties of the identified radio sources. This table was created by the HEASARC in March 2011 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/517/A54"&gt;CDS catalog J/A+A/517/A54&lt;/a&gt; file table2.dat.
