NASA HEASARC ingested the table in January 2011 and last updated it in September 2020.
A four-epoch infrared survey covering 10 square degrees in the Boötes field, conducted using the IRAC instrument on the Spitzer Space Telescope. The data, a Spitzer Cycle 4 Legacy project, consists of 20 band-matched catalogs with Vega magnitudes in four wavelengths. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
NASA HEASARC's RITTERRBIN table contains data on 500 related binary star objects, extracted from the 7.21 edition of the Ritter & Kolb catalog. The catalog compiles stellar parameters and orbital properties for detached binaries with white dwarf or white dwarf precursor primaries, incorporating literature published before 1 January 2014. This specific table was last updated by the HEASARC in April 2014.
10,979 variable stars in 35 stellar systems outside the Milky Way, including the Magellanic Clouds and the Andromeda Galaxy. This catalog is the electronically-readable version of the General Catalog of Variable Stars, Volume V, distributed by the Sternberg Astronomical Institute and Institute of Astronomy. NASA's HEASARC created this online version in January 2005 based on the CDS Catalog II/250.
Four-epoch infrared survey of 10 square degrees in the Boötes field, permitting the selection of variable and high proper motion objects over a wide field. The Spitzer Cycle 4 Legacy project data is sensitive to galaxies out to z ~ 3 with reduced cosmic variance impact. Catalogs from the National Aeronautics and Space Administration report Vega magnitudes for four IRAC bands with multiple aperture measurements.
NASA HEASARC provides two catalogs of astronomical objects identified in submillimeter maps from the James Clerk Maxwell Telescope. The Fundamental Map Object Catalog contains 5,061 objects, and the Extended Map Object Catalog contains 6,118 objects. The data were processed from raw archive observations downloaded in May 2006 and the table was created by HEASARC in December 2010.
IRAM, founded in 1979, studies cold matter in the universe using millimeter-wave observatories. This log summarizes observations from the six-antenna Plateau de Bure Interferometer in France between December 1, 1990, and March 31, 2017. The table was last updated by NASA HEASARC in July 2019.
The Fermi LAT Long-Term Transient Source Catalog contains 142 unique transient sources detected by the Fermi Large Area Telescope on monthly time intervals. NASA HEASARC ingested this catalog in September 2021, based on data from the Space Science Data Center. The catalog focuses on extragalactic regions and lists sources with a statistical significance above 4 sigma in at least one monthly bin.
NASA's HEASARC combined the 7-year high and low galactic latitude X-ray source catalogs from the MAXI Gas Slit Camera (GSC). The combined 3MAXI catalog contains 221 low-latitude and 686 high-latitude sources detected between 2009-08-13 and 2016-07-31. It includes source positions, fluxes, hardness ratios, variability metrics, and likely counterparts from cross-matching with other major X-ray catalogs.
A 2004 deep radio survey of the AKARI north ecliptic pole field, covering approximately 1.7 square degrees, produced this catalog of 462 sources. The survey used the Westerbork Radio Synthesis Telescope, achieving a sensitivity as low as 21 microJanskies/beam at 1.4 GHz. This table was created by the NASA HEASARC in March 2011 based on the CDS catalog J/A+A/517/A54.
NASA HEASARC provides a catalog of 110 discrete X-ray sources detected with greater than 3-sigma significance from a deep 98.2ks Chandra observation of the face-on spiral galaxy M 101. The catalog, created in July 2007, includes sources likely to be X-ray binaries, supersoft sources, and supernova remnants, with only approximately 27 expected to be background sources. The 29 brightest sources have sufficient flux for crude spectral modeling, with most fitted by a power-law and eight soft sources by a blackbody model.
935 galaxies with optical properties similar to Quasi-Stellar Objects, compiled by Hewitt and Burbidge in 1991. The catalog was created by NASA's HEASARC in February 2001 based on the CDS/ADC Catalog VII/178. Most objects are nonstellar, with over 700 having redshifts z <= 0.2, and are classified as Seyfert galaxies, N systems, or radio galaxies.
The CfA Redshift Survey South Galactic Cap (CFA2S) Catalog contains redshifts for a sample of about 4300 galaxies with blue magnitude <= 15.5, covering a specific region of the sky. Redshifts for 2964 of these galaxies were measured as part of the second CfA Redshift Survey, revealing large-scale structures like voids and the Perseus-Pisces Supercluster. This table was created by NASA's HEASARC in March 2005 based on data from the Center for Astrophysics.
The Galactic bulge and center within 4 degrees of the Galactic center are covered by this catalog of X-ray point sources. It contains 1159 sources from deep Chandra observations of three low-extinction Window fields and four other bulge fields, including Sgr B2 and Sgr A*. NASA HEASARC created this table in January 2010 based on a reference paper from the Astrophysical Journal.
Over 400 X-ray sources were resolved in the first phase of the XMM-Newton Galactic Plane Survey, covering approximately 3 square degrees. The table contains results from 22 pointings, revealing source populations in soft and hard X-ray bands with a flux limit of ~2e-14 erg/s/cm². This catalog was created by NASA HEASARC in February 2005 based on CDS data.
A four-epoch infrared survey of 10 square degrees in the Boötes field, conducted by the Spitzer Space Telescope's IRAC instrument. The data, produced by NASA as a Spitzer Cycle 4 Legacy project, consists of 20 band-matched catalogs reporting Vega magnitudes in four wavelengths. It is designed to characterize galaxy evolution beyond redshift 1.5 and select variable objects.
A four-epoch infrared survey of 10 square degrees in the Boötes field, conducted using the IRAC instrument on the Spitzer Space Telescope. The dataset consists of 20 band-matched catalogs from the Spitzer Deep, Wide-Field Survey (SDWFS), a Cycle 4 Legacy project, providing Vega magnitudes in four IRAC bands. It was created by the National Aeronautics and Space Administration and last updated in March 2026.
NASA HEASARC provides a catalog of approximately 7,000 confirmed quasars and other active galactic nuclei (AGN) identified as X-ray sources. The data results from a cross-correlation of X-ray data from the ROSAT All Sky Survey with optical imaging and spectroscopic data from the Sloan Digital Sky Survey Data Release 5, covering 5,740 square degrees of sky. This table was created in February 2007, replacing a previous version based on earlier SDSS data releases.
Spitzer, NASA's fourth Great Observatory, carries an 85-cm cryogenic telescope and three instruments for infrared imaging and spectroscopy from 3.6 to 160 microns. This table from NASA HEASARC contains the weekly-updated log of executed and scheduled observations, derived from files provided by the Spitzer Science Center. It was launched in August 2003 with a 2.5-year cryogenic requirement, though a 5-year mission was considered possible.
54 gamma-ray sources detected by the AGILE satellite between July 2007 and October 2009. The catalog includes source coordinates, detection significance, flux, variability indices, and counterpart classifications. NASA HEASARC created this table in December 2013 based on data from the reference paper.
