The Galactic plane from -20 to +120 degrees in longitude, with latitude coverage varying from +/- 0.8 to +/- 2.7 degrees. This table contains the New Catalog of Compact Radio (20-cm) Sources from White et al. (2005), created by combining archival data with Very Large Array observations. It covers about 331 square degrees, is 90% complete at a 14 mJy flux density threshold, and records over 5000 sources.
A catalog of over 2,700 compact radio sources at a 6-cm wavelength, covering 43 square degrees of the Galactic plane. The catalog was created by White et al. in 2005 by combining archival data with new observations from the Very Large Array. It provides a 50% increase in the number of high-reliability compact sources in the surveyed region with improved astrometry and uniformity.
An all-sky catalog presenting positions, proper motions, magnitudes, and star/galaxy estimators for 1,042,618,261 objects. The data were derived from 3,643,201,733 observations across 7,435 Schmidt plates taken over approximately 50 years. The catalog was constructed by the United States Naval Observatory and is mirrored by the Mikulski Archive for Space Telescopes (MAST).
260 galaxy groups were identified from the combined CfA and Southern Sky Redshift Surveys, covering one-quarter of the sky. The catalog, published in 2000, includes X-ray detections for 61 groups (23%) and presents median properties like velocity dispersion and X-ray luminosity. This table was created by NASA's HEASARC in 2005 based on data from the Center for Astrophysics.
The Australia Telescope 20-GHz Survey Bright Source Sample is a flux-limited catalog of 320 extragalactic radio sources south of declination -15 degrees. Observations were conducted with the Australia Telescope Compact Array from 2004 to 2007, with near-simultaneous multi-frequency data for a subset. NASA HEASARC created this table in August 2008 based on source files from the CDS.
792 Sloan Digital Sky Survey quasars observed serendipitously in X-rays by the XMM-Newton satellite. The catalog covers a redshift range of z = 0.11 - 5.41 and includes 70 radio-loud and 51 broad absorption line quasars. This table was created by NASA's HEASARC in July 2009 based on data published in the Astrophysical Journal.
1,045,175,762 celestial objects are cataloged in this all-sky dataset derived from nearly 7,500 photographic plates. The United States Naval Observatory created USNO-B1.0 to improve upon earlier catalogs by including objects detected in the same band at two epochs and those with significant proper motions. Data originates from five complete coverages of the northern sky and four of the southern sky taken between 1949 and 2002.
Statistical Source Data for Supplementary Figures and Figs.1-5 and Extended Data Figs.1-10 accompanies research on a modular nucleic acid-based construct for tumor delivery. The dataset includes unprocessed gels and Western Blots. It was authored by Weihong Tan and last updated on June 4, 2026.
ROSETTA-ORBITER 67P RSI 1/2/3 PRELANDING 0230 V1.0 is a Radio Science dataset from NASA's Rosetta mission, providing global gravity measurements of comet 67P/Churyumov–Gerasimenko. The data was collected during the PRELANDING mission phase between 2014-01-21 and 2014-11-18, with a specific measurement interval on 2014-08-22. It represents a direct scientific observation from a historic planetary mission.
412 quasars observed by XMM-Newton from 2 to 25 epochs each provide 1,376 observations for analyzing X-ray variability. The data, covering redshifts from ~0.2 to ~4.5 and luminosities from ~10^43 to ~10^46 erg/s, was created by the HEASARC in April 2012. It uses the structure function method to analyze ensemble variability across a large sample of active galactic nuclei.
A game-based educational activity introduces high school students to NMR spectroscopy through a crime story. The package includes 4-6 hours of introductory lessons and a 2-hour fictional investigation, with all supporting materials and original data provided. The dataset was created by Alberto Fraccarollo and last updated on May 13, 2026.
Approximately 800 type 1 active galactic nuclei and quasars were analyzed to explore the link between radio and X-ray emission. The catalog, created by NASA HEASARC in 2012, presents derived properties like black hole masses, bolometric luminosities, and Eddington ratios. Data was cross-matched from the 2XMMi X-ray, SDSS DR7 optical, and FIRST radio catalogs, covering redshifts from 0.3 to 2.3.
1055 compact X-ray sources detected within 29 nearby star-forming galaxies, compiled from Chandra, Spitzer, GALEX, and 2MASS archives. The catalog was created by NASA's HEASARC in March 2012 to study high-mass X-ray binaries and their scaling with star formation rate. It was used to construct an average X-ray luminosity function with improved statistical accuracy over previous studies.
Power spectrum frame data derived from Bluetooth Low Energy baseband signals, collected for RF fingerprint-based IoT device authentication. The dataset contains 20,000 NumPy array files (500 per module) from 40 distinct BLE transmitter modules, sampled at 20 MHz in the 2.4 GHz band. It was created by Hyeon Park, G. Cho, and T. Kim from Korea University and last updated on 2026-04 16.
A dataset containing the chemical composition of Incoloy 800H alloy in weight percent. The composition was determined by spectroscopy analysis and verified against standard composition ranges reported in the literature. The dataset was authored by Palanisamy Angappan and last updated on May 12, 2026.
22.2 per 1,000 children is the estimated ASD prevalence from a two-phase epidemiological study of 34,847 students in grades 1–3 in Russia. The research by Oksana I. Talantseva, published in 2026, utilized instruments like SCQ, ADOS-2, and ADI-R for identification and applied Bayesian regression to correct for screening misclassification.
Oligonucleotides used to dissect the roles of SPO11–1 and SPO11–2 paralogs in Leishmania hybridization within sand flies. The 10.8 KB XLSX file, authored by Carolina M. C. Catta-Preta and last updated in April 2026, is shared under a CC-BY-4.0 license on figshare. This dataset likely contains the primer or probe sequences employed for targeted gene deletions, mutant construction, and expression analyses.
Darwin Harbour, Australia, was the site for a study on the effect of sewage-derived nutrient loads on biogeochemical processes in mangrove-lined tidal creeks. The dataset likely contains measurements from three field surveys comparing water quality, sediment composition, benthic and pelagic metabolism, and nutrient fluxes across three creeks with differing pollution levels. The data was published via the Australian Ocean Data Network and was last updated on 2026-04-28.
Calcareous nannofossil assemblages from the Challenger No. 1 well in the offshore Perth Basin, Western Australia. The data, provided by Geoscience Australia, revises the age of the Challenger Formation type section and identifies three major disconformities within the Late Cretaceous-Palaeogene sequence. The section is described as more complete than coeval sections from nearby Deep Sea Drilling Project sites.
Palynological analysis of the marine Oligocene-Miocene sequence from the Oakvale-1 corehole in the western Murray Basin, South Australia. The dataset, provided by Geoscience Australia Data, contains diverse and well-preserved assemblages of spores, pollen, and dinoflagellate cysts, with records for numerous extant Australian taxa and the first Australian fossil records for some pollen types. A quantitative zonation based on major pollen taxa frequencies divides the sequence into two major zones, with the younger zone further subdivided into four sub-zones.
