The central field of the Andromeda galaxy (M 31) was monitored from 2006 to 2012, with archival data starting in 1999, using the Chandra HRC-I detector. NASA compiled a catalog of 318 X-ray point sources from 64 observations totaling about 1 Ms exposure time, providing long-term variability information over 13 years. The catalog includes 115 X-ray binary candidates and 14 globular cluster candidates, aiding the study of X-ray populations in a neighboring spiral galaxy.
The nearby galaxy M 83 (4.61 Mpc away) was observed using the Chandra X-ray Observatory. The catalog contains 378 point sources within the galaxy's D25 contour, derived from 790 ks of total exposure time combining new and archival observations. The data was produced by NASA and includes classifications for sources such as supernova remnants and X-ray binaries.
IRAM NOEMA observation log summarizes observations from the Northern Extended Millimeter Array, a French-German-Spanish radio astronomy facility. The table was originally ingested by NASA HEASARC in August 2017 and last updated in September 2020. It is based on tables obtained from the CDS and provides a service record for the NOEMA interferometer, which evolved from a three-antenna array in 1988 to an eight-antenna array by 2016.
From July 9, 2007 to June 30, 2008, the AGILE satellite detected 47 high-confidence gamma-ray sources. The Italian Space Agency (ASI) mission catalog includes 21 pulsars, 13 blazars, and other celestial objects like supernova remnants. NASA HEASARC created this table in March 2010 based on data from the Gamma-Ray Imaging Detector (GRID).
A 2009 catalog of 707 X-ray-emitting F, G, K, and M stars, created by NASA HEASARC. The dataset combines X-ray data from the ROSAT All-Sky Survey with optical data from the Sloan Digital Sky Survey (SDSS) and other catalogs to identify stellar counterparts. It includes derived distances and X-ray luminosities for the stars.
28,358 radio sources with spectral indices between -1.0 and +0.4, assembled to study the radio/gamma-ray connection in blazars. The catalog was created by NASA HEASARC in July 2014 based on a reference paper, combining observations from the WENSS, WISH, and NVSS surveys. It is intended for future searches for blazar-like counterparts of gamma-ray sources.
3,944 radio sources detected above a ~5-sigma threshold in the Spitzer extragalactic First Look Survey field. Observations were taken at 610 MHz with the Giant Metrewave Radio Telescope, covering ~4 square degrees with a resolution of 5.8 x 4.7 arcsec. The catalog was created by the HEASARC in February 2012 based on a CDS release corrected for a positional rounding error.
154 high-significance X-ray point sources were detected in the SB(s)m galaxy NGC 55 as part of the Chandra Local Volume Survey. The HEASARC created this table in September 2015 based on machine-readable data from the reference paper, which includes hardness ratios and cross-correlations with Hubble Space Telescope observations. Combined archival Chandra observations provide an effective exposure time of 56.5 ks, with sources detected down to a limiting luminosity of ~5e35 erg/s.
Full-resolution electron counts and accumulation times from the Ulysses spacecraft's High Energy Telescope, recorded every 64 seconds. The data, organized by eight 45-degree spin sectors, primarily capture electrons in the approximate 5-10 MeV energy range. It was produced by NASA's COSPIN investigation, with daily files available from at least 1990 to 2002.
NASA HEASARC provides a catalog of 692 active galactic nuclei (AGN) and their host galaxies from the COSMOS field, with redshifts between 0.1 and 4. The table, created in July 2017, summarizes multi-wavelength properties derived from X-ray and far-infrared data, including AGN luminosity, host galaxy stellar mass, and star formation rates. This data was used to investigate correlations between supermassive black hole growth and galaxy build-up.
Markus Bredel et al. analyzed gene expression in a set of 50 human gliomas to identify functions and pathways linked to gliomagenesis. The dataset includes 31 pure glioblastomas, 14 tumors with oligodendroglial morphology, and 5 grade 1-3 astrocytomas, with 351 clones revealed as significantly linked to the disease.
Ground-based images of comet 19P/Borrelly captured in the R filter at the Kitt Peak 2.1m telescope. The data covers three nights from September 21-23, 2001, bracketing the Deep Space 1 spacecraft encounter. Raw and reduced images are included, and the dataset is provided by the National Aeronautics and Space Administration.
20 nights of CCD images and photometry of comet 19P/Borrelly collected by astronomer Karen Meech. The data spans from 1987-08-21 to 2002-02-03 and was provided by the National Aeronautics and Space Administration. The original description notes these data were not of sufficient quality for formal review or ingestion.
Voyager 2 Planetary Radio Astronomy (PRA) instrument data captured during the Uranus encounter from 1985-10-24 to 1988-07 14. Each file represents a 48-second high-rate frame containing 1280000 octets of data, with a 28-octet header detailing time, spacecraft, and frequency information. The data were collected by NASA and consist of 16-bit numbers representing flux measurements at two frequencies sampled every 138.88 µs.
VG2-J-PRA-3-RDR-LOWBAND-6SEC-V1.0 contains calibrated radio wave data from the Voyager 2 Planetary Radio Astronomy instrument during its Jupiter encounter. The dataset covers the full encounter phase from 1979-04 25 to 1979-08-04 at a 6-second resolution, measuring left and right circular power across 70 low-frequency channels. It was produced by the National Aeronautics and Space Administration and is provided in ASCII format.
NASA's GES DISC provides an annual average climatology of planetary boundary layer (PBL) height derived from GPS radio occultation measurements by the COSMIC/FORMOSAT-3, TerraSAR-X, KOMPSAT-5, and PAZ satellite constellations. The data is generated by calculating the height of minimum vertical refractivity gradient for each occultation, a method detailed in Ao et al. (2012). This collection, last updated in March 2026, is the latest version and supersedes previous releases.
Supplementary Material 1 from a study integrating transcriptomic and metabolomic analyses of Pseudostellaria heterophylla, a medicinal plant. The dataset, published on figshare by Lin Tang in April 2026, is a 765.8 KB XLSX file. Its specific content likely includes gene expression and metabolite measurements related to light-quality-dependent regulation of specialized metabolism.
