Spitzer Space Telescope's SAGE-SMC project mapped the Small Magellanic Cloud at 24 microns to study galaxy evolution. The Epoch 1 catalog contains point-like sources meeting strict criteria, including a correlation value >0.89 and signal-to-noise >5, filtering out approximately two-thirds of initial entries. This data, produced by NASA, provides constraints on source variability for evolved stars and young stellar objects.
The Chandra-COSMOS Bright Source Catalog version 2.1 contains 1,761 sources detected in the 0.5-7 keV band from the Chandra-COSMOS survey. This survey probes galaxy formation across 75% of the universe's age, covering a 2 square degree equatorial field with data from Hubble, Spitzer, and other major telescopes. The catalog was produced by NASA, with methods and results detailed in associated papers from 2009.
SAGE-SMC is a legacy program from the Spitzer Space Telescope Cycle 4, led by Karl Gordon at STScI. The catalog provides infrared photometry of sources in the Small Magellanic Cloud, processed with strict detection criteria requiring a signal-to-noise ratio greater than 5 or 7 across IRAC bands. The data includes observations from two epochs separated by 3 months to mitigate instrument artifacts and constrain source variability.
5184 candidate infrared counterparts to 9017 X-ray sources detected by the Chandra Observatory near the Galactic center. NASA HEASARC created this catalog in October 2009 from published research, providing probabilities for real associations. The data distinguishes red and blue infrared sources to separate foreground objects from those near the Galactic center.
The SAGE-SMC project is a Spitzer Space Telescope legacy program surveying the Small Magellanic Cloud. This dataset is a combined full list of sources extracted from MIPS 160 micron mosaics across multiple observation epochs. The data was produced by the National Aeronautics and Space Administration and last updated in March 2026.
Zotatifin demonstrated a >4-log10 reduction in Mayaro virus titers at 50 nM. This dataset likely contains results from cytotoxicity and antiviral activity assays across multiple cell lines and virus strains, supporting the compound's potential as a pan-antiviral drug. The data was published by Patricia Valdés-Torres on figshare in March 2026.
501 X-ray sources were detected in the 0.3-8.0 keV band across six Chandra observations of the 16.5-Mpc distant elliptical galaxy NGC 4649, totaling 299 ks of exposure. The catalog, created by the HEASARC in March 2013 based on NASA data, includes source properties, counts, and hardness ratios, with luminosities ranging from 9.3e36 to 5.4e39 erg s^-1. Nine sources are candidates for ultraluminous X-ray sources, and 173 are associated with globular clusters.
Spitzer Space Telescope's SAGE-SMC project mapped the Small Magellanic Cloud at two epochs separated by 3 to 9 months to remove imaging artifacts and constrain source variability. The archive contains source fluxes with fewer nulled wavelengths than the project's stricter catalog, though these additions have more uncertainty. This data was produced by NASA and last updated in March 2026.
The SAGE-SMC project is a Spitzer Space Telescope legacy program mapping the Small Magellanic Cloud at infrared wavelengths. Observations were conducted at two epochs separated by 9 months for MIPS data to remove artifacts and constrain source variability. The catalog includes sources meeting criteria for point-like correlation and a signal-to-noise ratio greater than 5.
A legacy program from the Spitzer Space Telescope Cycle 4, the SAGE-SMC project surveyed the Small Magellanic Cloud. The dataset contains a full list of sources extracted from MIPS 70-micron mosaics across multiple observation epochs. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
A catalog of approximately 200 radio sources per field from deep 3.1-GHz observations of four sky fields (ELAIS-N1, Coma, Lockman Hole, NDWFS). The data comprises 459 repeated observations taken approximately daily between May 2009 and April 2011 by the Allen Telescope Array, covering 11.8 square degrees per image. The HEASARC created this table in March 2013 based on source lists from a 2013 paper.
Spitzer Space Telescope Cycle 4 legacy program data mapping the Small Magellanic Cloud at 160 microns. The catalog combines observations from two epochs separated by 9 months to remove imaging artifacts and constrain source variability. NASA produced this dataset as part of the SAGE-SMC project, with initial results described by Gordon et al. in 2010.
Over 2 million galaxies are detected in the COSMOS survey, spanning 75% of the age of the universe. The VLA Deep Catalog combines 275 hours of 1.4 GHz observations from 2004-2005 with an additional 62 hours from 2006, covering a 2 square degree equatorial field. The final combined survey has reached a sensitivity of micro-Jansky per beam in the central region at a resolution of 2.5 arcseconds.
A multi-epoch infrared catalog from the Spitzer Space Telescope's SAGE-SMC legacy program, mapping the Small Magellanic Cloud. The data includes observations from three epochs (Epoch 0, 1, and 2) separated by months to remove imaging artifacts and constrain source variability. The catalog was produced by a team led by Karl Gordon (STScI) and is hosted by the National Aeronautics and Space Administration.
z0MGS DR1 is an archival project from NASA combining WISE and GALEX images of nearby galaxies. The main sample consists of approximately 11,000 galaxies likely within 50 megaparsecs, with an additional ~5,000 galaxies included. The dataset provides integrated stellar mass and star formation rate measurements for each galaxy.
The CMa R1 star-forming region covers approximately 5 square degrees. This catalog lists X-ray sources detected by the ROSAT satellite, with complementary VRI photometry from the Gemini South telescope, used to identify young stellar populations. The HEASARC at NASA created this online catalog in April 2010 based on data from the CDS.
19,369 galaxies form the Updated Zwicky Catalog (UZC), a foundational resource for the CfA redshift surveys. The catalog provides corrected coordinates with ~2 arcsecond errors and homogeneously estimated radial velocities for 98% of the CfA spectra. This database was created by NASA's HEASARC in 2000 based on a 1999 publication from the Center for Astrophysics.
313 elliptical galaxies, groups, and clusters of galaxies were analyzed using ASCA archival data to measure X-ray properties of their hot gas. The study, compiled by NASA, systematically derived luminosity-temperature relations and gas mass scaling, with 292 objects used for correlation analysis. The data was last updated in March 2026.
The z0MGS archival project combines WISE and GALEX images of nearby galaxies. The main sample consists of approximately 11,000 galaxies with a high probability of being within 50 megaparsecs and having an absolute magnitude brighter than -18, plus images for about 5,000 additional galaxies. This dataset, released by NASA, includes an index with integrated stellar mass and star formation rate measurements for each galaxy.
Spitzer Space Telescope infrared observations of the Small Magellanic Cloud captured at three distinct epochs to remove imaging artifacts and constrain stellar variability. The data archive, produced by NASA's SAGE-SMC project, contains source fluxes with fewer nulled wavelengths than the project's official catalog, though with greater associated uncertainty. The archive excludes sources within a 0.5" radius, while the catalog uses a 2" radius for neighbor culling.
