58 X-ray point sources, supernova remnants, and H II regions detected in the central 6 kpc region of galaxy NGC 2403 using archival Chandra observations totaling ~180 ks. The catalog was created by NASA using data from four observations between 2001 and 2004, with sources identified via a signal-to-noise ratio threshold and spectral fitting. The distribution of X-ray emission is compared to morphology at other wavelengths using Spitzer, GALEX, and H-alpha imagery.

It was created by NASA HEASARC in March 2011 based on data from the CDS catalog.
Three regions totaling 520 square degrees were surveyed with the Ryle Telescope at 15 GHz to identify foreground sources for the Very Small Array's cosmic microwave background observations. The catalog contains 465 sources above a 25 mJy completeness limit, with a subset of 242 sources within three specific circular fields covering 286.5 square degrees.

BAX (Base de Donnees Amas de Galaxies X) is a multi-wavelength database dedicated to X-ray clusters and groups of galaxies. The catalog, created by NASA's HEASARC in October 2004, provides access to published measurements of physical quantities like coordinates, redshift, flux, luminosity, and temperature, along with bibliographic references. It is designed to support astronomical research from proposal planning to data interpretation using facilities like XMM-Newton, Chandra, and Planck.
The 9th Cambridge survey catalog of 643 radio sources observed at 15.2 GHz using the Ryle Telescope, created by NASA HEASARC in November 2010. The data covers multiple survey regions with areas of 529, 115, and 29 square degrees, complete to flux density limits of approximately 25, 10, and 5.5 mJy, respectively. The catalog was compiled to support the Very Small Array cosmic microwave background telescope and includes matched data from the 1.4 GHz NVSS catalog.
The Chandra bulge field observations target the central quarter of the Galactic Plane. The catalog contains 2596 X-ray point source candidates from ~900 ks of total exposure time using the Chandra ACIS-I instrument, retrieved from 10 archived data sets taken between May and August 2008. The analysis aims to constrain the nature of these sources and their contribution to the Galactic Ridge X-ray emission in the hard band.
The Small Magellanic Cloud survey provides X-ray data covering 6.32 square degrees of the bar and eastern wing. This catalog contains 3,053 unique X-ray point sources, including 49 confirmed high-mass X-ray binaries and 72 active galactic nuclei, detected in 100 observations between April 2000 and April 2010. It was produced by the National Aeronautics and Space Administration using the XMM-Newton satellite.
NASA's HEASARC provides a refined set of 652 binary star systems with reliable orbits and determined parallaxes. The dataset, created in October 2014, includes three mass estimates (dynamical, photometric, spectroscopic), main orbital elements, and component magnitudes and spectral types. It was compiled from the Observatorio Astronomico Ramon Maria Aller Catalog (OARMAC), the Sixth Catalog of Orbits of Visual Binary Stars (ORB6), and updated information from the Washington Double Star (WDS) Catalog and SIMBAD.
5.8 Ms of Chandra X-ray observations reveal 4442 point sources across 38 nearby galaxies. The catalog supports analysis of X-ray luminosity functions for high-mass and low-mass binary populations. NASA HEASARC created this table in April 2023 based on published astrophysical research.
846 radio-quiet quasars detected by the ROSAT satellite's All-Sky Survey or pointed observations, compiled by Yuan et al. in 1998. The catalog includes X-ray flux densities, photon indices, and absorption column densities derived from ROSAT data, with optical positions sourced from the 1993 Veron-Cetty & Veron catalog. NASA's HEASARC created this database in December 1998 based on the original publication.
A catalog of 1,691 High Synchrotron Peaked blazars and candidates, assembled by cross-matching multi-wavelength surveys and applying spectral slope criteria. The 2WHSP sample was created by the authors of the referenced paper and ingested by NASA's HEASARC in February 2017. It is described as the largest and most complete list of HSP blazars available to date.
A 2019 catalog from NASA HEASARC details the X-ray properties of 105 supernova remnants in the M 33 galaxy, detected using an eight-field XMM-Newton mosaic survey. The study includes 54 newly X-ray-detected remnants and three newly discovered ones, with detailed spectral fitting for 15 objects using combined XMM-Newton and Chandra data. The authors used this sample to construct an X-ray luminosity function and analyze environmental effects on remnant detectability.
The 2XMMi/SDSS Galaxy Cluster Survey is a catalog of 530 X-ray-selected galaxy groups and clusters compiled by cross-matching the XMM-Newton Serendipitous Source Catalog with optical data from the Sloan Digital Sky Survey. The catalog, hosted by NASA, provides photometric and spectroscopic redshifts, X-ray fluxes, luminosities, temperatures, and cluster mass estimates. It includes 345 clusters with spectroscopic X-ray parameters and 185 with catalog-derived fluxes, superseding a previous release of 175 clusters.
73 XMM-Newton and 28 Chandra detections of point-like X-ray sources in the starburst galaxy IC 10, with observations from 2003. The catalog was created by the HEASARC in October 2011 based on source files from the CDS.
NASA HEASARC provides a catalog of spectroscopic identifications for 77 bright, soft X-ray sources from the ROSAT All-Sky Survey. The table contains identifications for 70 sources, with 5 identified by other means, and presents subsidiary information for 2 unidentified sources. The largest source classes are Seyfert 1 galaxies, magnetic cataclysmic variables, and hot white dwarfs.
The Arcminute Microkelvin Imager (AMI) Galactic Plane Survey provides arcminute-resolution images of the outer Galactic plane at milli-Jansky sensitivity. This first data release catalog contains 3,503 radio sources detected above 5 sigma from 868 square degrees of sky, observed at a central frequency of 15.75 GHz. The NASA HEASARC ingested this catalog in 2013 based on data from the CDS.
8,479 bright M dwarf stars form the most complete collection of K < 9th magnitude M dwarfs currently available. The catalog was created by NASA HEASARC in 2015, combining new candidates from the PPMXL catalog with previous work for future exoplanet transit studies. It includes 1,193 new bright M dwarf candidates not in earlier catalogs, identified using optical/NIR color and reduced proper motion cuts.
The Faint Sky Variability Survey Catalog contains a sample of 598 galaxy clusters and rich groups identified from the FSVS data. The clusters were discovered using an automated, semi-parametric technique based on maximum likelihood applied to Voronoi tessellation and enhanced by color discrimination. The table was created by NASA's HEASARC in July 2006 based on the original author's data.
106 X-ray point sources detected in the interacting galaxy pair NGC 1512/NGC 1510 by the XMM-Newton space telescope. The catalog was produced by NASA using a single 63-ks observation on 2012 June 16-17, with sources classified via spectral analysis and cross-correlation with optical, infrared, and radio catalogs. It includes 15 sources within the galaxies' D25 regions and characterizes diffuse emission from NGC 1512.
100 compact groups of galaxies were identified from a systematic search of the Palomar Observatory Sky Survey. The catalog includes dynamical parameters for 92 of the groups and was created by NASA HEASARC based on tables from the ADC/CDS data centers, with refinements made in 2005. This database table contains the information from key 1982 and 1992 astrophysical journal publications.
