The HCGGALAXY table contains data on 463 galaxies within 100 compact groups identified from the Palomar Observatory Sky Survey. NASA HEASARC created the table in 1999, based on machine-readable tables from the ADC/CDS data centers, and updated it in 2005. It provides astrometry, photometry, morphological types, and radial velocities for the galaxies, drawing from three key astronomical publications.
937 X-ray point sources detected in deep Chandra observations of the Extended Groth Strip between 2007 and 2009. The catalog, created by NASA HEASARC in 2016, includes multiwavelength identifications for 94% of sources and provides spectroscopic or photometric redshifts for all, with photometric redshifts achieving a mean accuracy of sigma = 0.04. This survey is the third deepest X-ray survey, covering an area of approximately 0.29 square degrees.
29,089 X-ray sources detected from 4,303 ROSAT HRI pointed observations with exposure times longer than 100 seconds. The catalog was generated using a multi-scale wavelet detection algorithm and provides positions, count rates, fluxes, and extensions for each source, along with cross-correlations with other wavelength catalogs. NASA HEASARC ingested this catalog in March 2003.
NASA HEASARC provides a catalog of 449 radio sources detected at 1.4 GHz in a 30-arcmin diameter region centered on the ROSAT/XMM-Newton 13-hour deep field. The survey combined 24 hours of Very Large Array data to achieve a 7.5 microJansky noise limit and a 4-sigma detection threshold of 30 uJy at the map center. This table was created in July 2013 based on data from the CDS catalog J/MNRAS/352/131.
1319 X-ray sources detected in a 4 square-degree survey of the Milky Way's plane by the XMM-Newton satellite. The dataset, produced by NASA's Survey Science Centre, includes 316 spectroscopically identified sources, primarily active stars, cataclysmic variables, and young stellar objects, observed at flux limits as low as 2×10⁻¹⁵ erg/cm²/s. This collection represents the largest group of identified low-latitude X-ray sources at its sensitivity level.
1658 unique X-ray sources identified by the Chandra X-ray Observatory across a 12 square degree area of the Galactic Bulge. The catalog is based on the Chandra source lists from Jonker et al. (2011) and Jonker et al. (2014), published by NASA. The survey was designed to be shallow and wide-area, with a homogeneous depth to a specific X-ray flux, to maximize the detection of low-mass X-ray binaries.
The ACTSOUTH catalog is a multi-frequency, multi-epoch catalog of 695 extragalactic sources based on observations from the Atacama Cosmology Telescope in 2008-2010. It covers a sky area of approximately 600 square degrees and classifies sources into 374 synchrotron and 321 dusty emitters. NASA HEASARC ingested this table in November 2023 from the LAMBDA archive.
147 serendipitous X-ray sources with hard spectra (spectral indices Alpha < 0.5) were selected from a survey of 188 ROSAT fields. The catalog, created by NASA HEASARC in March 2012, suggests these hard sources are dominant contributors to the X-ray background at faint fluxes. Monte Carlo simulations indicate the survey's effective area for hard sources is >=10 times greater than for soft sources above a specific flux level.
The Herschel Space Observatory log details observations from the European Space Agency's mission, which operated from May 2009 to April 2013. It includes data from three instruments (PACS, SPIRE, HIFI) covering the far-infrared and sub-millimeter spectral range (55-671 microns). The log contains information on 241 Open Time programs from OT1, totaling 6576.9 hours, and 42 Key Programs.
An 80.7 square degree region of the ROSAT North Ecliptic Pole Survey provides a catalog of 219 Active Galactic Nuclei (AGN). The catalog, created by NASA HEASARC in August 2005 and last updated in March 2026, features complete optical identifications and spectroscopic redshifts, with a median redshift of z = 0.41.
321 extragalactic sources from the Chandra Deep Field South 1 Ms catalog have detailed X-ray spectral properties analyzed, including power-law slopes and intrinsic absorption. The analysis uses optical spectroscopy and photometric redshifts, with a weighted mean power-law slope of 1.75 +/- 0.02. This table was created by NASA's HEASARC in August 2007 based on published catalog data.
A catalog of 1230 discrete radio emitters detected at 1.4 GHz in the GOODS-North field, a region covering approximately 160 square arcminutes. The data were obtained from 165 hours of Very Large Array observations between February 2005 and February 2006 and processed by NASA HEASARC in September 2013. The observations achieved a dynamic range of 6800:1 and an rms noise level as low as ~3.9 microJansky per beam.
The Chandra Deep Field North 2-Megasecond Optical and IR Catalog from NASA HEASARC provides multicolor imaging for 503 X-ray point sources and spectroscopic redshifts for 284 sources. It includes six high-redshift type II quasars and shows that 68% of the measured 2-8 keV light arises from sources at redshift less than 2. The optical imaging data consist of Johnson B, V, Cousins R, I, and Sloan z' observations from the Subaru telescope in 2001 and 2002.
The Planck Catalog of Galactic Cold Clumps (PGCC) is an all-sky catalog of 13,188 Galactic cold clump candidates detected by the Planck satellite using 48 months of mission data. It is the full version of the 2011 Early Cold Core catalog and includes sources with median temperatures between 13 and 14.5K, ranging from low-mass cores to large molecular clouds. The catalog, created by the HEASARC in March 2019 based on CDS data, also contains 54 sources in the Magellanic Clouds.
A catalog of 100,563 unresolved, UV-excess quasar candidates from the Sloan Digital Sky Survey Data Release One, covering 2099 square degrees. The National Aeronautics and Space Administration's HEASARC created this table in August 2005 based on published astronomical data. Existing spectra of 22,737 sources indicate a 97.6% quasar efficiency, with authors estimating 95.0% of the catalog objects are quasars.
155 discrete, non-nuclear ultraluminous X-ray sources with luminosities exceeding 10^39 erg/s, identified in 82 galaxies observed by NASA's Chandra X-ray Observatory. The catalog, created by the HEASARC in March 2007, contains positions, luminosities, and spectral and timing characteristics for these sources. Analysis suggests correlations with host galaxy star formation, merging, and interactions.
350 X-ray sources were detected in the spiral galaxy M 33, with 39 being newly identified. The catalog results from analyzing 24 archival XMM-Newton observations, providing improved positions and variability analysis on timescales from hours to years. This table was created by NASA's HEASARC in March 2007 based on data from the CDS.
The catalog covers 17% of the sky and contains information on 235 extreme ultraviolet sources, including 169 new detections. NASA HEASARC created this database in May 2002, derived from published tables, based on observations made after the first catalog in January 1994. It provides source count rates and probable identifications from four specific photometric wavelength bands.
