The NEOWISE Post-Cryo survey scanned approximately 70% of the sky after the WISE telescope's cryogen was exhausted. This list from NASA contains predicted associations of known asteroids and comets with individual WISE single-exposure images, where objects may have multiple entries. Data was generated during the Post-Cryo phase when the W1 and W2 detectors operated near 73.5 K.
A COSMOS X-ray group membership catalog combines X-ray group properties with mass estimates from weak lensing and member galaxy information. The catalog covers a 2 square degree equatorial field and includes over 2 million galaxies spanning 75% of the age of the universe. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
The SAGE-SMC project mapped the Small Magellanic Cloud using the Spitzer Space Telescope's MIPS instrument at 24 microns. This dataset is the full list of sources extracted from the Epoch 1 mosaics, filtered for point-like sources with a correlation value >0.89 and signal-to-noise >5. The program was led by Karl Gordon (STScI) as a Cycle 4 legacy project, with initial results described in a 2010 paper.
466 radio sources cataloged to a 5-sigma sensitivity from the Australia Telescope Hubble Deep Field-South survey. The catalog results from observations with the Australia Telescope Compact Array conducted from 1998 to 2001. NASA HEASARC created this table in November 2012 based on the published source catalog.
A 1999 catalog from NASA HEASARC containing 516 astrophysical objects selected for strong ultrasoft X-ray emission from the Einstein IPC database of 5934 sources. Selection was based on X-ray 'color' ratios from three broad energy bands, with identified objects including active galactic nuclei, stellar objects, and Galactic sources. The catalog was created by the HEASARC based on tables provided to the CDS/ADC.
A 2 square degree equatorial field surveyed by major space and ground-based telescopes provides data on over 2 million galaxies spanning 75% of the age of the universe. The catalog contains structural and morphological measurements from the Zurich Estimator of Structural Type (ZEST) and Single-Sersic GIM2D fits, as presented in two 2007 ApJS publications. This v1.0 catalog is based on the May 2006 release of Alexie Leauthaud's ACS catalog.
A 2014 catalog from NASA HEASARC classifies 883 radio sources detected at 1.4 GHz in the Extended Chandra Deep Field-South. The authors used a combination of Very Large Array radio, Chandra X-ray, and Spitzer mid-infrared data to disentangle star-forming galaxies, radio-quiet, and radio-loud active galactic nuclei. The table also compares host galaxy properties like morphology, optical colors, and stellar masses for the three classes.
The ROSAT Bright Survey (RBS) is a catalog of over 2000 X-ray sources detected at high galactic latitude during the ROSAT All-Sky Survey. The identification program is more than 99.5% complete and includes 669 X-ray selected AGN and 302 galaxy clusters. This electronic version was created by NASA HEASARC in August 2000 based on a table supplied by Axel Schwope.
SAGE-SMC is a Spitzer Space Telescope legacy program surveying the Small Magellanic Cloud to understand galaxy evolution. The IRAC Epoch 1 catalog contains sources detected under strict criteria, requiring a signal-to-noise ratio greater than 5 or 7 across four infrared bands and detection in at least 60% of observations at a given wavelength. This data was produced by NASA and last updated in March 2026.
SAGE-SMC is a Spitzer Space Telescope legacy program surveying the Small Magellanic Cloud. The dataset contains full lists of sources extracted from MIPS 24 micron mosaics across three observational epochs, designed to remove imaging artifacts and constrain source variability. The project was led by Karl Gordon (STScI) and data is provided by the National Aeronautics and Space Administration.
A catalog of point-like sources at 24 microns from the Spitzer Space Telescope's SAGE-SMC legacy program. The data includes observations from three epochs (Epochs 0, 1, and 2) separated by months to remove imaging artifacts and constrain source variability. The project was led by Karl Gordon (STScI) and data reduction followed the methodology of the S3MC pathfinder survey.
318 compact radio sources detected at 34.5 GHz within 30 arcseconds of the Galactic center's supermassive black hole, Sgr A*. The catalog, created by NASA HEASARC in 2016, includes 45 sources with identified near-infrared stellar counterparts from VLT/NACO observations. Data from 2011 and 2014 VLA radio observations were used to investigate proper motions and mass-loss rates of massive stars.
58,738 astronomical objects comprise the CfA Redshift Catalog, incorporating velocity data from sources like the Whipple Observatory and earlier compilations. The NASA HEASARC assembled this version in February 2001 based on the June 1995 release from CDS/ADC. It was primarily created for studying the large-scale structure of the universe.
A Cycle 4 legacy program on the Spitzer Space Telescope, the SAGE-SMC project surveyed the Small Magellanic Cloud. The IRAC Epoch 1 archive contains infrared image data from the Spitzer Infrared Array Camera, processed to remove artifacts and constrain source variability. The data was produced by the project team with Karl Gordon (STScI) as Principal Investigator and is hosted by the National Aeronautics and Space Administration.
8000 Galactic HII regions and candidates identified by their mid-infrared morphology using WISE satellite data. This catalog from NASA is the most complete record of massive star formation in the Milky Way, with ~1500 sources confirmed by radio or Halpha emission. The catalog, last updated in March 2026, resolves complexes into individual sources and removes duplicates.
154 ks of deep X-ray observations from the Chandra ACIS instrument in 2000 and 2002 were used to identify 174 X-ray point sources in the giant elliptical galaxy M 87. The catalog, created by NASA HEASARC in 2007, contains ~150 likely low-mass X-ray binaries (LMXBs) and was cross-referenced with Hubble Space Telescope data to study their connection to globular clusters.
188 sources detected at signal-to-noise ratio > 4.5, including 141 synchrotron-dominated and 47 dust-dominated objects. The catalog results from a 607-hour survey covering 87 square degrees at 1.4 mm and 2.0 mm wavelengths with milli-Jansky depth. The data was produced by the National Aeronautics and Space Administration using the South Pole Telescope.
Over 2 million galaxies are detected in this catalog, spanning 75% of the age of the universe. It was created using u*-band priors and the EM-algorithm on GALEX NUV and FUV images covering the 2 square degree COSMOS equatorial field. The catalog is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
261,418,479 source detections in 3.4, 4.6, and 12 Ξm infrared bands from NASA's WISE telescope survey between 6 August 2010 and 29 September 2010. The data covers approximately 30% of the sky and includes positions and photometry, but contains spurious detections and artifacts. It serves as a working database to complement the more reliable WISE All-Sky Release Source Catalog.
COSMOS is an astronomical survey probing galaxy formation across 75% of the universe's age. This catalog, from NASA, identifies group members from the COSMOS ACS galaxy catalog, with corrections for charge transfer inefficiency applied to the raw Hubble Space Telescope images. The catalog is truncated at a magnitude limit of F814W < 24.2 and excludes objects within ACS masks and bad detections.
