A catalog of 1689 radio-continuum sources in the field of the Small Magellanic Cloud (SMC). The sources were detected at 843 MHz from a 36-square-degree survey conducted with the Molonglo Observatory Synthesis Telescope (MOST). This table was created by NASA's HEASARC in September 2014 based on an external catalog.
The Spitzer Extragalactic Representative Volume Survey (SERVS) program conducted deep infrared observations of five extragalactic fields. This catalog contains objects detected at 4.5 microns with a signal-to-noise ratio greater than 5, providing a deeper, single-band dataset for cross-matching. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
A deep infrared catalog from the Spitzer Extragalactic Representative Volume Survey (SERVS) for the CDFS field. The data contains objects observed at 4.5 microns with a signal-to-noise ratio cut of CSNR > 5 and a reliability flag of REL=1. It was produced by NASA's Spitzer Exploration Science program and last updated in March 2026.
518 extragalactic radio sources with flux densities greater than 1 Jy at 5 GHz, compiled from the NRAO-MPI and Parkes surveys. This catalog covers essentially the whole sky, excluding the galactic plane and the Magellanic Clouds, and includes flux densities, positions, object classes, visual magnitudes, redshifts, and spectral indices. NASA HEASARC provides this service, with a duplicate entry removed in June 2019.
The Spitzer Extragalactic First Look Survey catalog presents line ratio and extinction measurements from WIYN/Hydra spectra. The survey comprises 4 square degrees of mid-infrared imaging from the Spitzer Space Telescope, aimed at characterizing extragalactic sources. The catalog was produced by the National Aeronautics and Space Administration, with supporting data described in Marleau et al. (2007).
The Spitzer Extragalactic Representative Volume Survey (SERVS) conducted deep 3.6 and 4.5 micron observations of five extragalactic fields: ELAIS-N1, Lockman Hole, XMM, ELAIS-S1, and CDFS. This catalog from the XMM-LSS field contains single-band 3.6 micron detections with a signal-to-noise cut of CSNR > 5 and a reliability flag of REL=1. The data was produced by NASA and last updated in March 2026.
Five extragalactic fields, including the Lockman Hole, were observed by the Spitzer Space Telescope's SERVS program. The catalog contains deep 3.6 and 4.5 micron infrared observations from the IRAC instrument. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
109 bright, extended astronomical objects compiled by Charles Messier in the 18th century, with magnitudes brighter than 10 and angular sizes from 1 to 100 arcminutes. The catalog is provided by NASA HEASARC and includes 29 globular clusters, 27 open clusters, 27 spiral galaxies, 11 elliptical galaxies, 10 nebulae, and 5 miscellaneous objects. All objects are located north of -35 degrees declination.
EXOSAT satellite transmission grating spectrometer data provides X-ray spectra for astronomical sources. The data is organized into two databases: TGS for averaged spectra and TGS2 for separate positive and negative grating orders. NASA HEASARC maintains this service, last updated on 2026-03-13.
A single-band infrared catalog from the Spitzer Extragalactic Representative Volume Survey (SERVS) for the ELAIS-S1 field. It contains objects detected at 3.6 microns with a signal-to-noise ratio greater than 5 and high reliability. The data was produced by NASA's Spitzer Space Telescope Exploration Science program.
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 National Aeronautics and Space Administration provides two data products: a high-reliability Catalog and a more inclusive Archive of infrared sources. The data was collected as part of the Spitzer Cycle 4 Legacy program.
The Spitzer Extragalactic Representative Volume Survey (SERVS) provides deep infrared observations of five extragalactic fields, including ELAIS-N1. This specific catalog contains 4.5 micron data from the Spitzer Space Telescope's IRAC instrument, with objects selected for a signal-to-noise ratio greater than 5. It was produced by NASA and last updated in March 2026.
NASA HEASARC provides raw rates data from the Orbiting Solar Observatory-8 (OSO-8) spacecraft's GCXSE detectors. The data were collected from launch on 21 June 1975 until late September 1978, with rates accumulated every 160 ms in the 2-60 keV energy band. This database accesses the raw FITS data files for the three non-solar cosmic X-ray spectroscopy detectors.
Spectra and lightcurves obtained using the EXOSAT satellite's Transmission Grating Spectrometer (TGS). The data is provided in two processed forms: TGS, which averages positive and negative grating orders for a general overview, and TGS2, which keeps the orders separate for detailed analysis. This service is provided by NASA's High Energy Astrophysics Science Archive Research Center (HEASARC).
The Spitzer Extragalactic Representative Volume Survey (SERVS) catalog contains deep 3.6-micron infrared observations from NASA's Spitzer Space Telescope. It covers five extragalactic fields: ELAIS-N1, Lockman Hole, XMM, ELAIS-S1, and CDFS. The single-band catalog is optimized for depth and reliability, with objects selected at a signal-to-noise ratio greater than 5 and flagged for high reliability.
The Davis-Savant Standard provides a 10 GB unified forensic framework bridging neuroinformatics and cosmology. It corrects a 1.0-billion-year discrepancy in cosmic age estimates and includes a 1,300-region map of the Axial Core across 32 BIDS-compliant neuroinformatics datasets.
