XRISM Master Catalog
The X-Ray Imaging and Spectroscopy Mission (XRISM) is an international mission led by Institute of Space and Astronautical Science (ISAS) of Japan Aerospace Exploration Agency (JAXA). XRISM was launched on 2023 September 6 (UT) into a near-circular orbit with an apogee of ~575 km, an inclination of ~31 degrees, and an orbital period of about 96 minutes. During the performance verification (PV) phase, targets selected by the XRISM science team are being observed. Subsequently, it will become a general observatory with annual call for proposals open to all astronomers. XRISM has two co-aligned instruments that are used concurrently: Resolve, a soft X-ray spectrometer, and Xtend, a wide field-of-view imager. Resolve uses an X-ray microcalorimeter with ~5 eV spectral resolution withs a 3x3 arcmin field of view. It is currently operating with the Gate Valve closed, which limits its effective bandpass to 1.7-12 keV. Xtend is an X-ray CCD instrument with a 38 x 38 arcmin<sup>2</sup> field of view. This table contains a list of observations that have taken place as well as those that have been accepted and planned. The latter includes pre-approved targets for TOO observations and priority C targets whose observations are not guaranteed. This database table is based on information supplied by the XRISM Science Data Center at NASA/GSFC. It is updated automatically on a regular basis. This is a service provided by NASA HEASARC .

XMM-Newton Optical Monitor SUSS Catalog, v6.1: Observation IDs
공공데이터포털
The 2023 release of the XMM OM Serendipitous Ultraviolet Source Survey (XMM-SUSS6.1) Catalog, a catalog of optical/UV sources detected by the Optical Monitor (OM) on-board the European Space Agency's (ESA's) XMM-Newton observatory, spans the period of observations from 2000 to November 2022. The data processing was performed at the European Space Astronomy Centre (ESAC, Madrid, Spain) using the XMM Science Analysis Software system (SAS) versions 18 and 19. In addition to covering a larger observation period, this sixth release reflects a change in philosophy with regard to the origin of the incorporated data. In previous releases, the data were generated via a bespoke processing of the OM Observation Data Files (ODFs) while in this new release, the catalog has been guided by the XMM user community and the authors have sought to harmonize the contents of the catalog with those of the OM data in the XMM-Newton Science Archive (XSA), which derive from the standard XMM-Newton pipeline processing system. While the bespoke processing and pipeline systems are fundamentally very similar, they are not identical and the differences lead to some differences in the output. The number of observations (OBSIDs) included in the catalog is 12,057. This table (XMMOMSUOB) contains the list of these observations and their characteristics, giving for each observation the filters used, the exposure time for each filter, the number of sources detected in each filter and the detection magnitude limit for each filter. The total number of entries in this release is 9,920,390. They correspond to 6,659,554 unique sources, of which 1,225,117 have multiple entries in the source table, corresponding to different observations. This list of sources is available at the HEASARC as the XMMOMSUSS table. The documentation on the first release of this catalog is available at http://www.mssl.ucl.ac.uk/www_astro/XMM-OM-SUSS/Summary.shtml. This HEASARC database table contains the sixth release of the XMM-OM SUSS catalog, XMM-SUSS6.1, released by ESA in October 2023, obtained from the XMM-Newton Science Archive (http://xmm.esac.esa.int/xsa), and ingested into the HEASARC database in October 2023. It is also available at the HEASARC as the gzipped FITS file https://heasarc.gsfc.nasa.gov/FTP/xmm/data/catalogues/XMM-OM-SUSS6-1.1.fits.gz. This is a service provided by NASA HEASARC .
XMM-Newton COSMOS X-Ray Point Source Catalog
공공데이터포털
This table contains the XMM-Newton EPIC COSMOS X-ray point-like source catalog (XMM-COSMOS). The COSMOS survey is a multiwavelength survey aimed to study the evolution of galaxies, AGN and large scale structures. Within this survey, XMM-COSMOS is a powerful tool for detecting AGN and galaxy clusters. The XMM-COSMOS is a deep X-ray survey over the full 2 deg2 of the COSMOS area. It consists of 55 XMM-Newton pointings for a total exposure of ~1.5 Ms with an average vignetting-corrected depth of 40 ks across the field of view and a sky coverage of 2.13 deg2. The analysis was performed using the XMM-SAS data analysis package in the 0.5-2 keV, 2-10 keV and 5-10 keV energy bands. Source detection has been performed using a maximum likelihood technique especially designed for raster scan surveys. The completeness of the catalog as well as log N-log S and source density maps have been calibrated using Monte Carlo simulations. This is the catalogue of point-like X-ray sources detected with the EPIC CCD cameras. The catalogs contains a total of 1887 unique sources detected in at least one band with likelihood parameter det_ml > 10. The survey, which shows unprecedented homogeneity, has a flux limit of ~1.7 x 10-15 erg/cm2/s, ~9.3 x 10-15 erg/cm2/s and ~1.3 x 10-14 erg/cm2/s over 90% of the area (1.92 deg2) in the 0.5-2 keV, 2-10 keV and 5-10 keV energy bands, respectively. This table was created by the HEASARC in April 2009 based on the electronic version of Table 3 from the paper which was obtained from the CDS (their catalog J/A+A/497/635 file catalog.dat). It was last updated in May 2010 to correct the source number for XMMU J100100.7+015947 to be XMMC 129, as indicated by SIMBAD. This is a service provided by NASA HEASARC .

MAXI Master Catalog
공공데이터포털
The MAXIMASTER database table records high-level information of the Monitor of All-sky X-ray Image (MAXI) observations and provides access to the data archive. MAXI is a Japanese experiment located at the International Space Station (ISS), designed to continuously monitor, through a systematic survey, X-ray sources as the ISS orbits Earth. MAXI was launched by the space shuttle Endeavour on 2009 July 16, then mounted on port No. 1 on JEM-EF on July 24. After the electric power was turned on, MAXI started nominal observations on 2009 August 3. The MAXI data are a copy of the MAXI data processing; the output of which is hosted at the DARTS archive located at ISAS (https://darts.isas.jaxa.jp/astro/maxi/). This catalog is then generated at the HEASARC by collecting high-level information from the data and is updated regularly during operation. This is a service provided by NASA HEASARC .
XMM-Newton Galactic Plane Survey - XGPS
공공데이터포털
This table contains the first results from the XMM-Newton Galactic Plane Survey (XGPS). In the first phase of the program, 22 pointings were used to cover a region of approximately 3 square degrees between 19 and 22 degrees in Galactic Longitude and +/-0.6 degrees in Galactic Latitude. In total, over 400 point X-ray sources have been resolved at >=5-sigma significance, down to a flux limit of ~2 x 10-14 erg/s/cm2 (2-10 keV). The sources exhibit a very wide range of spectral hardness, with interstellar absorption identified as a major influence. The source populations detected in the soft (0.4 - 2 keV) band and hard (2 - 6 keV) band show surprisingly little overlap. The majority of the soft sources appear to be associated with relatively nearby stars with active stelaar coronae, judging from their high coincidence with bright stellar counterparts. The combination of the XGPS measurements in the hard X-ray band with the results from earlier surveys carried out by ASCA and Chandra reveals the form of the low-latitude X-ray source counts over 4 decades of flux. It appears that extragalactic sources dominate below ~10-13 erg/s/cm2 (2-10 keV), with a predominantly Galactic source population present above this flux threshold. The nature of the faint Galactic population observed by XMM-Newton remains uncertain, although cataclysmic variables and RS CVn systems may contribute substantially. This table was created by the HEASARC in February 2005 based on CDS Catalog J/MNRAS/351/31/tablea1.dat. This is a service provided by NASA HEASARC .
XTEProposalInfo&Abstracts
공공데이터포털
The XTEAO database table contains the official observing program for the Rossi X-Ray Timing Explorer (RXTE) satellite. This list contains the targets recommended by the review panels for the various Cycles of Guest Observer (GO) proposals up to and including Cycle 15. Notice that not all entries in this list will actually be observed, since it includes observations of Targets of Opportunity (ToOs) which may never be triggered. Also note that multiple pointings at a particular target are permitted. This database table was updated by the HEASARC periodically, based on information provided by the RXTE Guest Observer Facility (GOF). This is a service provided by NASA HEASARC .
COSMOS X-ray Group Member Catalog
공공데이터포털
COSMOS is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structural environment. The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra) and a number of large ground based telescopes (Subaru, VLA, ESO-VLT, UKIRT, NOAO, CFHT, and others). Over 2 million galaxies are detected, spanning 75% of the age of the universe.The reference for this catalog is George et al. (2011). This is a group membership catalog drawn from the COSMOS ACS galaxy catalog, similar to the one presented in Leauthaud et al. (2007). The main difference between this catalog and the Leauthaud et al 2007 one is that the raw ACS images have now been corrected for the effects of charge transfer inefficiency (CTI, see Massey et al. 2010 for further details). Since the CTI correction scheme slightly changes the noise properties of the raw images, the detections have also changed. For this reason, the GAL_ID field in this catalog can not be used to match to objects in the 2007 catalog. The pixel scale for this catalog is 0.03". To reference this ACS catalog please reference Leauthaud 2007 with updates presented in Leauthaud et al (in prep). This catalog is truncated at F814W (MAG_AUTO) < 24.2 due to the K-band completeness limit for stellar masses and because photoz uncertainties rise near this limit. Objects within ACS masks have also been removed (these are the same masks as in Leauthaud et al. 2007) and a variety of bad detections have been removed ("clean"=1 and "mu_class"=1) as well as galaxies without stellar masses.
XTE All-Sky Slew Survey Catalog
공공데이터포털
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)x10-11 erg/s/cm2 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 103 square degree area of the sky is sampled to flux levels below 10-11 erg/s/cm2 (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 > 1023 cm-2). This dataset enabled the authors to present for the first time a log N - log S diagram for extragalactic sources above 4 x 10-12 erg/s/cm2 at 8 - 20 keV. This database table was created by the HEASARC in May 2004 based on CDS Catalog J/A+A/418/927. This is a service provided by NASA HEASARC .

The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra) and a number of large ground based telescopes (Subaru, VLA, ESO-VLT, UKIRT, NOAO, CFHT, and others). Over 2 million galaxies are detected, spanning 75% of the age of the universe.This is a COSMOS X-ray group membership catalog, combining X-ray group properties from Finoguenov et al. (2007) with estimates for masses and radii calibrated from weak lensing (Leauthaud et al. 2010), and member galaxy information (George et al. 2011). Group redshifts have been determined by searching for red sequence overdensities within 500 kpc of the X-ray centers and are refined by using spectroscopic redshifts when available. We use groups with z<1 to ensure good optical identifications and small photoz uncertainties.
XMM-Newton Cluster Survey Catalog, DR1 Version
공공데이터포털
The XMM Cluster Survey (XCS) is a serendipitous search for galaxy clusters using all publicly available data in the XMM-Newton Science Archive. Its main aims are to measure cosmological parameters and trace the evolution of X-ray scaling relations. In their paper, the authors present the first data release from the XMM Cluster Survey (XCS-DR1). This consists of 503 optically confirmed, serendipitously detected, X-ray clusters. Of these clusters, 256 are new to the literature and 357 are new X-ray discoveries. They present 463 clusters with a redshift estimate (0.06 < z < 1.46), including 261 clusters with spectroscopic redshifts. The remainder have photometric redshifts. In addition, the authors have measured X-ray temperatures (kTX) for 401 clusters (0.4 < kTX < 14.7 keV). This table was created by the HEASARC in May 2013 based on CDS Catalog J/MNRAS/423/1024 file xcsdr1.dat. This is a service provided by NASA HEASARC .
