ROSAT All-Sky Survey/6dF Galaxy Survey Catalog of X-Ray Selected AGN

This table contains a catalog of 3405 X-ray sources from the ROSAT All Sky Survey (RASS) Bright Source Catalog which fall within the area covered by the 6dF Galaxy Survey (6dFGS). The catalog is count-rate limited at 0.05 ct s&lt;sup&gt;-1&lt;/sup&gt; in the X-ray and covers the area of sky with Declination &lt; 0 degrees and |b| &gt; 10 degrees. The RASS-6dFGS sample was one of the additional target catalogs of the 6dFGS and as a result the authors obtained optical spectra for 2224 (65 per cent) RASS sources. Of these, 1715 (77%) have reliable redshifts with a median redshift of z = 0.16 (excluding the Galactic sources). For the optically bright sources (b_J &lt;= 17.5) in the observed sample, over 90% have reliable redshifts. The catalog mainly comprises quasi-stellar objects (QSOs) and active galaxies but also includes 238 Galactic sources. Of the sources with reliable redshifts, the majority are type 1 active galactic nuclei (AGN, 69%), while 12% are type 2 AGN, 6% absorption-line galaxies and 13% are stars. The authors also identify a small number of optically faint, very low redshift, compact objects which fall outside the general trend in the b_J - z plane. The RASS-6dFGS catalog complements a number of Northern hemisphere samples, particularly the ROSAT Bright Source Catalogue-NRAO VLA Sky Survey (RBSC-NVSS) sample (Bauer et al. 2000, ApJS, 129, 547), and furthermore, in the same region of sky (-40 degrees &lt; Declination &lt; 0 degrees) reveals an additional 561 sources that were not identified as part of that sample. The authors detect 918 sources (27%) of the RASS-6dFGS sample in the radio using either the 1.4 GHz NVSS or the 843 MHz Sydney University Molonglo Sky Survey (SUMSS) catalogues and find that the detection rate changes with redshift. At redshifts larger than 1 virtually all of these sources have radio counterparts and with a median flux density of 1.15 Jy, they are much stronger than the median flux density of 28.6 mJy for the full sample. The authors attribute this to the fact that the X-ray flux of these objects is being boosted by a jet component, possibly Doppler boosted, that is only present in radio-loud AGN. The RASS-6dFGS sample provides a large set of homogeneous optical spectra ideal for future studies of X-ray emitting AGN. This table was created by the HEASARC in April 2010 based on an electronic version of Table 3 from the reference paper obtained from the MNRAS web site. This is a service provided by NASA HEASARC .

ROSAT PSPC M 31 Source Catalog

This catalog is the complete ROSAT PSPC Source List of X-ray sources found in two surveys of M 31 reported by Supper et al. (1997, 2001). These papers reported the results of the analysis of the two ROSAT PSPC surveys of M 31 performed in the summers of 1991 and 1992, respectively. summer 1992. Supper et al. (2001) compare and combine the results from the two surveys. In the first survey, 396 X-ray point sources were detected, and an identical number in the second survey, although this equality is coincidental, as the source lists are different and contain only 239 sources in common. Within the approximately 10.7 square degrees field of view of the second survey, 396 individual X-ray sources were detected, of which 164 sources were new detections. When combined with the first survey, this resulted in a total of 560 X-ray sources in the field of M 31. Their (0.1 keV-2.0 keV) fluxes range from 7 x 10&lt;sup&gt;-15&lt;/sup&gt; to 7.6 x 10&lt;sup&gt;-12&lt;/sup&gt; erg cm&lt;sup&gt;-2&lt;/sup&gt; s&lt;sup&gt;-1&lt;/sup&gt;, and of these 560 sources, 55 are tentatively identified with foreground stars, 33 with globular clusters, 16 with supernova remnants, and 10 with radio sources and galaxies (including M 32). A comparison with the results of the Einstein M 31 survey reveals 491 newly detected sources, 11 long-term variable sources, and 7 possible transient sources. Comparing the two ROSAT surveys, Supper et al. come up with 34 long-term variable sources and 8 transient candidates. For the M 31 sources, the observed X-ray luminosities range from 4 x 10&lt;sup&gt;35&lt;/sup&gt; to 4 x 10&lt;sup&gt;38&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt;. The total (0.1 keV-2.0 keV) luminosity of M 31 is (3.4 +/- 0.3) x 10&lt;sup&gt;39&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt;, distributed approximately equally between the bulge and disk. Within the bulge region, the luminosity of a possible diffuse component combined with faint sources below the detection threshold is (2.0 +/- 0.5) x 10&lt;sup&gt;38&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt;. An explanation in terms of hot gaseous emission leads to a maximum total gas mass of (1.0 +/- 0.3) x 10&lt;sup&gt;6&lt;/sup&gt; solar masses. The conversion of PSPC count rates into X-ray fluxes depends on the assumed spectral shape. For M 31-sources, a power law with photon index of -2.0 and an intervening column density pf 9 x 10&lt;sup&gt;20&lt;/sup&gt; H atoms cm&lt;sup&gt;-2&lt;/sup&gt; may be used, leading to the conversion factor of 1 ct/ksec = 3.00 x 10&lt;sup&gt;-14&lt;/sup&gt; erg cm&lt;sup&gt;-2&lt;/sup&gt; s&lt;sup&gt;-1&lt;/sup&gt; in the 0.1-2.0 keV broad band. For foreground stars, the application of this conversion factor leads to an over-estimate of the fluxes. This online catalog was created by the HEASARC in October 2001 based on machine-readable tables obtained from the ADC/CDS data centers (their catalog J/A+A/373/63, and table table6.dat).

Ultraluminous X-Ray Sources in Nearby Galaxies Catalog

One hundred and seven ultraluminous X-ray sources (ULXs) with 0.3-10.0 keV luminosities in excess of 10&lt;sup&gt;39&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt; are identified in a complete sample of 127 nearby galaxies. The sample includes all galaxies within 14.5 Mpc above the completeness limits of both the Uppsala Galaxy Catalogue and the Infrared Astronomical Satellite survey. The galaxy sample spans all Hubble types, a four-decade range in mass, 7.5 &lt; log (M/M&lt;sub&gt;sun&lt;/sub&gt;) &lt; 11.4, and in star formation rate, 0.0002 &lt; SFR(M&lt;sub&gt;sun&lt;/sub&gt; yr&lt;sup&gt;-1&lt;/sup&gt;) &lt;= 3.6. ULXs are detected in this sample at rates of one per 3.2 x 10&lt;sup&gt;10&lt;/sup&gt; M&lt;sub&gt;sun&lt;/sub&gt;, one per ~0.5 M&lt;sub&gt;sun&lt;/sub&gt; yr&lt;sup&gt;-1&lt;/sup&gt; star formation rate, and one per 57 Mpc&lt;sup&gt;3&lt;/sup&gt; corresponding to a luminosity density of ~2 x 10&lt;sup&gt;37&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt; Mpc&lt;sup&gt;-3&lt;/sup&gt;. At these rates, the authors estimate as many as 19 additional ULXs remain undetected in fainter dwarf galaxies within the survey volume. An estimated 14 objects, or 13%, of the 107 ULX candidates are expected to be background sources. The differential ULX luminosity function shows a power-law slope alpha ~ -0.8 to -2.0 with an exponential cutoff at ~20 x 10&lt;sup&gt;39&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt; with precise values depending on the model and on whether the ULX luminosities are estimated from their observed numbers of counts or, for a subset of candidates, from their spectral shapes. Extrapolating the observed luminosity function predicts at most one very luminous ULX, L&lt;sub&gt;X&lt;/sub&gt; ~ 10&lt;sup&gt;41&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt;, within a distance as small as 100 Mpc. The luminosity distribution of ULXs within the local universe cannot account for the recent claims of luminosities in excess of 2 x 10&lt;sup&gt;41&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt;, requiring a new population class to explain these extreme objects.

BeppoSAX Wide Field Camera X-Ray Source Catalog

This table contains the catalog of X-ray sources detected by the two Wide Field Cameras (WFCs) in complete observations on board BeppoSAX during its 6 years of operational lifetime, i.e., between April 1996 and April 2002. The BeppoSAX WFCs were coded mask instruments sensitive in the 2 - 28 keV energy band with a 40 x 40 square degree fields of view, pointing in opposite directions and perpendicularly to the BeppoSAX Narrow Field Instruments (NFI). The WFCs were usually operated simultaneously to NFI observations, each lasting up to several days. The WFCs observed thus the entire sky several times with a typical sensitivity of 2 to 10 mCrab. A systematic analysis of all WFC observations in the BeppoSAX archive has been carried out using the latest post-mission release of the WFC analysis software and calibrations. The catalog includes 253 distinct sources, obtained from a total sample of 8253 WFC detections. This table was created by the HEASARC in November 2007 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/472/705"&gt;CDS catalog J/A+A/472/705&lt;/a&gt; file table3.dat.

INTEGRAL IBIS 9-Year Galactic Hard X-Ray Survey Catalog

The INTEGRAL observatory operating in a hard X-ray/gamma domain has gathered a large observational data set over nine years starting in 2003. Most of the observing time was dedicated to the Galactic source population study, making possible the deepest Galactic survey in hard X-rays ever compiled. The authors aimed to perform a Galactic survey that could be used as the basis of Galactic source population studies, and performed mapping of the Milky Way in hard X-rays over the maximum exposure available at Galactic latitudes |b| &lt; 17.5 degrees. They used sky reconstruction algorithms especially developed for the high quality imaging of INTEGRAL/IBIS data. In their paper. they presented sky images, sensitivity maps, and catalogs of detected sources in the three energy bands 17 - 60, 17 - 35, and 35 - 80 keV in the Galactic plane at |b| &lt; 17.5 degrees. The total number of sources in the reference 17 - 60 keV band includes 402 objects exceeding a 4.7-sigma detection threshold on the nine-year time-averaged map. Among the identified sources with known and tentatively identified natures, 253 are Galactic objects (108 low-mass X-ray binaries, 82 high-mass X-ray binaries, 36 cataclysmic variables, and 27 are of other types), and 115 are extragalactic objects, including 112 active galactic nuclei and 3 galaxy clusters. The sample of Galactic sources with S/N &gt; 4.7 sigma has an identification completeness of ~92%, which is valuable for population studies. Since the survey is based on the nine-year sky maps, it is optimized for persistent sources and may be biased against finding transients. This table contains the catalog of 402 INTEGRAL sources exceeding the detection threshold in the 17 - 60 keV energy band. This table was created by the HEASARC in September 2012 based on CDS CATALOG J/A+A/545/A27 file catalog.dat. This is a service provided by NASA HEASARC .

Chandra Serendipitous Extragalactic X-Ray Source ID (SEXSI) Catalog

The Serendipitous Extragalactic X-Ray Source Identification (SEXSI) program is designed to extend greatly the sample of identified extragalactic hard X-ray (2 - 10 keV) sources at intermediate fluxes (~10&lt;sup&gt;-13&lt;/sup&gt; to 10&lt;sup&gt;-15&lt;/sup&gt; erg/cm&lt;sup&gt;2&lt;/sup&gt;/s). SEXSI, which studies sources selected from more than 2 deg&lt;sup&gt;2&lt;/sup&gt;, provides an essential complement to the Chandra Deep Fields, which reach depths of 5 x 10&lt;sup&gt;-16&lt;/sup&gt; erg/cm&lt;sup&gt;2&lt;/sup&gt;/s (2 - 10 keV) but over a total area of less than 0.2 deg&lt;sup&gt;2&lt;/sup&gt;. In their published paper, the authors describe the characteristics of the survey and their X-ray data analysis methodology. They present the cumulative flux distribution for the X-ray sample of 1034 hard sources and discuss the distribution of spectral hardness ratios. Their log N -log S in this intermediate flux range connects to those found in the Deep Fields, and by combining the data sets, they constrain the hard X-ray population over the flux range in which the differential number counts change slope and from which the bulk of the 2 - 10 keV X-ray background arises. They further investigate the log N - log S distribution separately for soft and hard sources in the sample, finding that while a clear change in slope is seen for the softer sample, the hardest sources are well described by a single power law down to the faintest fluxes, consistent with the notion that they lie at lower average redshift. In the SEXSI program, fields were selected with high Galactic latitude (|b| &gt; 20 degrees) and with declinations accessible to the optical facilities available to the authors (declination &gt; -20 degrees). They used observations taken with Chandra&#39;s Advanced Camera for Imaging Spectroscopy (ACIS I- and S-modes; Bautz et al., 1998, Proc. SPIE, 3444, 210) only (for sensitivity in the hard band). All the fields presented in this paper have data that are available in the Chandra public archive. This table was created by the HEASARC in June 2004 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/596/944/table4"&gt;CDS Catalog J/ApJ/596/944/table4&lt;/a&gt;.dat which is a representation of Table 4 from the published version.
