- RXTE All-Sky Slew Survey catalog, |b|>10{deg}
- Short Name:

- Publisher:

- Description:
- We report results of a serendipitous hard X-ray (3-20keV), nearly all-sky (|b|>10{deg}) survey based on RXTE/PCA observations performed during satellite reorientations in 1996-2002. The survey is 80% (90%) complete to a 4{sigma} limiting flux of ~1.8 (2.5)x10^-11^erg/s/cm^2^ in the 3-20keV band. The achieved sensitivity in the 3-8keV and 8-20keV subbands is similar to and an order of magnitude higher than that of the previously record HEAO-1 A1 and HEAO-1 A4 all-sky surveys, respectively. A combined 7x10^3^~sq.deg area of the sky is sampled to flux levels below 10^-11^erg/s/cm^2^ (3-20keV). In total 294 sources are detected and localized to better than ~1{deg}. 236 (80%) of these can be confidently associated with a known astrophysical object; another 22 likely result from the superposition of 2 or 3 closely located known sources. 35 detected sources remain unidentified, although for 12 of these we report a likely soft X-ray counterpart from the ROSAT all-sky survey bright source catalog. Of the reliably identified sources, 63 have local origin (Milky Way, LMC or SMC), 64 are clusters of galaxies and 100 are active galactic nuclei (AGN). The fact that the unidentified X-ray sources have hard spectra suggests that the majority of them are AGN, including highly obscured ones (N_H_>10^23^cm^-2^). For the first time we present a logN-logS diagram for extragalactic sources above 4x10^-12^erg/s/cm^2^ at 8-20keV.

- XTE All-Sky Slew Survey AGN Catalog
- Short Name:

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains the RXTE All-Sky Slew Survey Catalog of AGN and AGN candidates. The catalog authors compiled a sample of 95 AGNs which were serendipitously detected in the 3-20 keV band at Galactic latitude |b| > 10 degrees during the RXTE Slew Survey (XSS, Revnivtsev et al., CDS Cat. <J/A+A/418/927>), and utilized it to study the statistical properties of the local population of AGN, including the X-ray luminosity function and absorption distribution. They find that among low X-ray luminosity (L<sub>X</sub> < 10<sup>43.5</sup> erg/s) AGN, the ratio of absorbed (characterized by intrinsic absorption in the range 10<sup>22</sup> cm<sup>-2</sup> < N<sub>H</sub> < 10<sup>24</sup> cm<sup>-2</sup>) and unabsorbed (N<sub>H</sub> < 10<sup>22</sup> cm<sup>-2</sup>) objects is 2:1, while this ratio drops to less than 1:5 for higher luminosity AGN. The summed X-ray output of AGN with L<sub>X</sub> > 10<sup>41</sup> erg/s estimated here is smaller than the earlier estimated total X-ray volume emissivity in the local Universe, suggesting that a comparable X-ray flux may be produced together by lower luminosity AGN, non-active galaxies and clusters of galaxies. The authors also presented a sample of 35 AGN candidates, composed of unidentified XSS sources. Most of these AGN belong to the local population (z < 0.1). For each confirmed AGN source, the following information is provided: AGN class, the count rate in two energy bands (3-8 keV and 8-20 keV), the observed and intrinsic (absorption-corrected) luminosity in the 3 - 20keV band, and the intrinsic absorption column density. For the AGN candidates, composed of unidentified XSS sources, the following information is provided: the count rate in two energy bands (3-8 keV and 8-20 keV), the estimated intrinsic absorption column density, and information about RASS Bright Source Catalog and HEAO A-1 X-ray source counterparts. This table was created by the HEASARC in December 2004 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/423/469">CDS Catalog J/A+A/423/469</a>, table1.dat and table2.dat (the corrected version of 01-Dec-2004).

- Description:
- The Rossi X-Ray Timing Explorer (RXTE) All-Sky Survey Slew Catalog contains the results of a serendipitous hard X-ray (3 - 20 keV), nearly all-sky (|b|>10 degrees) survey based on observations by RXTE's Proportional Counter Array (PCA) which were performed during satellite reorientations in the period 1996 - 2002. The survey is 80% (90%) complete to a 4-sigma limiting flux of ~1.8 (2.5)x10<sup>-11</sup> erg/s/cm<sup>2</sup> in the 3 - 20 keV band. The achieved sensitivity in the 3 - 8 keV and 8 - 20 keV subbands is similar to and an order of magnitude higher than that of the previously record HEAO-1 A1 and HEAO-1 A4 all-sky surveys, respectively. A combined 7 x 10<sup>3</sup> square degree area of the sky is sampled to flux levels below 10<sup>-11</sup> erg/s/cm<sup>2</sup> (3 - 20 keV). In total 294 sources are detected and localized to better than ~1 degree; 236 (80%) of these can be confidently associated with a known astrophysical object; 22 of these sources have multiple counterparts (17 have 2 counterparts and 5 have 3 counterparts) with which they have been identified, and as these are listed as separate entries, there are 321 entries in this table. 35 detected sources remain unidentified, although for 12 of these we report a likely soft X-ray counterpart from the ROSAT all-sky survey bright source catalog. Of the reliably identified sources, 63 have a local origin (Milky Way, LMC or SMC), 64 are clusters of galaxies and 100 are active galactic nuclei (AGN). The fact that the unidentified X-ray sources have hard spectra suggests that the majority of them are AGN, including highly obscured ones (hydrogen column density > 10<sup>23</sup> cm<sup>-2</sup>). This dataset enabled the authors to present for the first time a log N - log S diagram for extragalactic sources above 4 x 10<sup>-12</sup> erg/s/cm<sup>2</sup> at 8 - 20 keV. This database table was created by the HEASARC in May 2004 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/418/927">CDS Catalog J/A+A/418/927</a>.

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table was created for the purpose of providing a comprehensive, accurate, and easily accessible tracking of Rossi X-Ray Timing Explorer (RXTE) pointed observations. It does not list observations made during slews: those are listed in the <a href="/W3Browse/xte/xteslew.html">XTESLEW</a> database table. The XTEMASTER table includes both observations that have already completed and those still scheduled to be done. The XTEMASTER table is regenerated automatically on a quasi-regular basis whenever the RXTE Science Operations Facility (SOF) updates their short-term or long-term schedules and transfers the new version(s) to the HEASARC. At that time, it will also incorporate all the latest information on which targets have been observed (using the daily RXTE ObsCats at <a href="https://heasarc.gsfc.nasa.gov/FTP/xte/timelines/obscat/">https://heasarc.gsfc.nasa.gov/FTP/xte/timelines/obscat/</a>) and which observations have been archived in the public RXTE Data Archive at <a href="https://heasarc.gsfc.nasa.gov/FTP/xte/data/archive/">https://heasarc.gsfc.nasa.gov/FTP/xte/data/archive/</a>.
