The Extragalactic First Look Survey comprises 4 square degrees of mid-infrared imaging from the Spitzer Space Telescope, observed for 67 hours in late 2003. This catalog presents line strength and equivalent width measurements from follow-up WIYN/Hydra optical spectra, as described in Marleau et al. (2007). The data was published by the National Aeronautics and Space Administration and last updated on the platform in March 2026.
The Spitzer Survey of Stellar Structure in Galaxies (S4G) catalog contains photometry and model parameters for over 2300 nearby galaxies observed at 3.6 and 4.5 microns. This extremely deep survey from NASA reaches a 1 sigma surface brightness limit of μ3.6(AB) = 27 mag arcsec-2. The catalog provides derived parameters and links to data access pages for each galaxy.
A catalog of 1,441 X-ray point sources detected in 32 nearby spiral and elliptical galaxies by the Chandra ACIS observatory. The table lists source properties such as counts in energy bands, hardness ratios, and inferred X-ray luminosities. This table was created by the NASA HEASARC in October 2006 based on data from the CDS.
The Great Observatories Origins Deep Survey (GOODS) unites deep observations from NASA's Spitzer, Hubble, and Chandra, ESA's Herschel and XMM-Newton, and ground-based facilities. This catalog lists sources from MIPS 24 micron imaging of the GOODS-S field, limited to flux densities greater than 80 microJy for high completeness and reliability. The data is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
A ~24 square degree region of the Cygnus-X star-forming complex was imaged by the Spitzer Space Telescope's IRAC and MIPS instruments. The project provides two catalog data products: a high-reliability Catalog and a more inclusive Archive with fainter sources. This data was collected as part of the Spitzer Cycle 4 Legacy program (PID 40184) by the National Aeronautics and Space Administration.
The Lynds' Catalog of Bright Nebulae lists coordinates, dimensions, area, color, and a brightness index on a scale from 1 to 6 for each object. It originates from the NASA/ADC CD-ROM 'Selected Astronomical Catalogs Vol. 1' dated 09-July-1992, with corrections added by the CDS and a revision by NASA HEASARC in February 2001. The catalog includes cross-references to other major catalogs like NGC, IC, and Sharpless.
GLIMPSE360 is a catalog of infrared point sources from NASA's Spitzer Space Telescope. It maps 187 degrees of Galactic longitude not covered by previous surveys, completing full coverage of the Galactic plane. The catalog provides fluxes, positions, and quality flags for high-reliability sources.
Spitzer Extragalactic Representative Volume Survey (SERVS) provides deep 4.5 micron observations of five extragalactic fields, including the Lockman Hole. This single-band catalog from NASA prioritizes depth and statistical completeness by including objects with a signal-to-noise ratio greater than 5 and excluding low-coverage edges. It is designed for cross-matching with other reliable catalogs or for statistical studies requiring a high number of potential matches.
304 gamma-ray burst afterglows observed over 14 years, containing 2,995 flux density measurements. The catalog, compiled from VLA, EVLA, and ATCA radio telescopes, was used to analyze detection rates and peak radio luminosities. Authors from NASA used the data to produce synthetic light curves and predict behavior for new telescope arrays.
URAT is a follow-up project to the UCAC catalog, using the same astrograph but with a larger focal plane array and a redder bandpass. Longer integration times and more sensitive CCDs resulted in a 4-fold increase in the average number of stars per square degree compared to UCAC, with positional precision improved through multiple sky overlaps per year. The catalog, published by the National Aeronautics and Space Administration, includes observations of stars as bright as about 3rd magnitude via an objective grating.
NASA HEASARC's GRB Afterglow catalog contains intensity and redshift measurements from ground and space-based telescopes. The catalog records afterglow measurements for bursts detected after May 1996, with multiple entries per GRB from different observatories. It was compiled by the author(s) in 2005 and ingested by HEASARC in June 2008, with updates when new measurements are reported.
IMP 8 Cosmic Ray Nuclear Composition (CRNC) data provides 15-minute-resolution particle count rates from the spacecraft's Low Energy and main telescopes. The dataset includes counts for electrons, protons, helium nuclei, and CNO nuclei across specified energy bands, as documented by the National Aeronautics and Space Administration. Data is accessible via FTP and was last updated on 2026-03 13.
Daily netCDF files from the AIM satellite's Cosmic Dust Experiment (CDE). Level 1 data contains time tags, pulse heights, electron counts, and engineering data for each dust grain impact. Level 2 data adds particle mass and spacecraft location, with future levels planned for orbital mass totals and correlation with cloud brightness.
Nannofossil and planktic foraminiferal data from three marginal-marine sections in the Indo-Pacific region analyze the timing of key species appearances around the Oligocene-Miocene boundary. The study, published by the Australian Ocean Data Network, investigates discrepancies in biostratigraphic events between shallow and deep oceanic sediments. It proposes a combined planktic foraminiferal zone and a buffer zone to represent the boundary transition.
Radio Science data from the Rosetta orbiter's PRELANDING phase, specifically measuring the global gravity field of comet 67P/Churyumov-Gerasimenko. The National Aeronautics and Space Administration collected this data during a specific 10-hour window on 2014-10-21. This dataset provides direct physical measurements of the comet's mass distribution from the historic Rosetta mission.
A repository unifying governance theory, strategic thought, frontier physics, and extreme engineering into a single integrated knowledge system. The dataset, authored by 'water, Spring' and hosted on the Spring water Dataverse, was last updated on May 20, 2026. Contents likely include theoretical models, engineering specifications, and strategic analyses spanning political systems and physical constants.
Sequences of the primers and oligos used in this study. The dataset is a small 11.3 KB Excel file authored by Han-cheng Wei and published under a CC-BY-4.0 license on figshare. It was last updated on May 4, 2026.
February 2007 to December 2017 observations from the Swift observatory's Burst Alert Telescope. The catalog contains 1,891 hard X-ray sources in the 14-195 keV band, with 259 new detections, and classifies them into 17 astrophysical categories. Data reduction and analysis were conducted by NASA following established procedures from previous survey catalogs.
A whole exome sequencing screening of 385 infertile female subjects and 400 controls identified 29 TUBB8 gene variants, of which 23 were novel. The study, led by Wei Zheng from the Reproductive & Genetic Hospital CITIC-Xiangya, expands the variant spectrum and reports new phenotypes like large polar body. These findings aim to lay a foundation for future genetic counseling of infertile women.
A catalog of 206 radio sources detected in the Perseus star-forming complex using the Karl G. Jansky Very Large Array. The data includes 42 sources associated with young stellar objects and was collected in multi-epoch observations during 2011. The catalog was created by the HEASARC in February 2018 based on tables from the reference paper.
