Numerical modeling results investigate the role of bed morphology in driving changes in ice-sheet extent and dynamics for the Lambert-Amery system in East Antarctica. The analysis focuses on the post-Oligocene period, particularly the Miocene Epoch and Pliocene-Pleistocene history. This dataset was published by the Australian Ocean Data Network and was last updated in April 2026.
SwiftFT is a catalog of point sources detected by the Swift satellite's X-ray Telescope in observations centered on gamma-ray bursts from January 2005 to December 2008. The catalog was generated from 374 fields covering ~32.55 square degrees, with a total exposure of 36.8 Ms. It was produced by NASA with international participation, using the XIMAGE package to detect sources in three X-ray energy bands.
Planck, a European Space Agency mission launched in 2009, mapped the entire sky across frequencies from 30 to 857 GHz. The Second Planck Catalogue of Compact Sources (PCCS2) lists discrete Galactic and extragalactic objects detected from the full mission data, superseding earlier versions. It includes polarization measurements for seven channels and is divided into the PCCS2 and PCCS2E subcatalogs based on detection reliability in different sky regions.
The South Ecliptic Pole region contains observations of 159 radio sources with 20-GHz flux densities >= 200 mJy. The Planck-ATCA Co-eval Observations (PACO) project collected data between 4.5 and 40 GHz for 482 sources, with this faint sample catalog containing 674 observations of 152 sources. Observations were conducted almost simultaneously with the Planck satellite between July 2009 and August 2010 by the Australia Telescope Compact Array.
The Australia Telescope 20-GHz survey catalog provides polarization data for 187 extragalactic sources brighter than 500 mJy at 20 GHz and with Declination below -30 degrees. The sample is 99% complete for its selection criteria and has a 91.4% polarization detection rate at ~20 GHz, with multi-frequency observations for 172 sources. This table was created by the NASA HEASARC in January 2015 based on data from a dedicated 2006 observing run with the Australia Telescope Compact Array.
The XMM-Newton Large-Scale Structure survey covers approximately 3 square degrees of sky. This table contains reliable optical spectroscopic identifications for 487 X-ray sources, increasing the number of known identifications in the field by a factor close to 5, obtained with the Anglo-Australian Telescope in 2006 and 2007. It was created by NASA HEASARC in July 2010 based on a published catalog.
1037 radio source entries from Giant Metrewave Radio Telescope observations at 610 MHz in the XMM-Large Scale Structure field. The catalog includes 592 single sources and 445 components of multiple sources, complementing earlier surveys at 74, 325, and 1400 MHz to form a multifrequency catalog of 1611 sources. This table was created by NASA HEASARC in February 2012 based on the original catalog J/A+A/471/1105.
74 highly significant X-ray point sources were detected in NGC 404, the closest face-on S0 galaxy to the Milky Way, as part of the Chandra Local Volume Survey. The catalog was created by combining a new 97-ks Chandra ACIS-S observation with archival data for a total exposure of ~123 ks, and originally published in Binder et al. (2013). It is sensitive to a limiting unabsorbed luminosity of ~6 x 10^35 erg/s in the 0.35-8 keV band.
765 radio sources detected at 150 MHz by the Giant Metrewave Radio Telescope, covering a 15 square degree area. The catalog, created by NASA's HEASARC in 2012, provides spectral indices for 83% of its sources, with a median of 0.78, and identifies about 150 sources with spectra steeper than 1 as candidate high-redshift radio galaxies.
Planck, a European Space Agency mission launched in 2009, mapped the sky across frequencies from 30 to 857 GHz. The Second Planck Catalogue of Compact Sources (PCCS2) lists discrete Galactic and extragalactic objects detected in single-frequency maps from the full mission, superseding earlier versions. It includes polarization measurements for seven channels and aims for 80% integral reliability.
2,151 high-redshift source candidates detected by the Planck mission in the cleanest 26% of the sky. The catalog, created by NASA using a component-separation method on Planck and IRAS data, identifies luminous cold sub-millimeter sources with flux density above 500 mJy at 545 GHz. First follow-up observations suggest the list contains two populations: a small fraction of strongly lensed galaxies and a majority of overdensities of dusty star-forming galaxies, potentially proto-clusters.
The full-duration Planck mission (2009-2013) mapped the entire sky across frequencies from 30 to 857 GHz. The Second Planck Catalogue of Compact Sources (PCCS2) lists discrete Galactic and extragalactic objects detected in these single-frequency maps, superseding earlier versions. It was produced by the European Space Agency and NASA, with improved processing increasing the number of objects for a target 80% reliability.
8,264 radio sources cataloged from surveys spanning nearly 20 years with the Parkes radiotelescope. The catalog, compiled by John Bolton and colleagues, covers the sky south of declination +27 degrees and combines radio data at frequencies from 80-22,000 MHz with optical identifications and redshifts. This version (1.01) corrects errors from a prior release and was updated by the HEASARC in July 2015.
2008-2018 observations from the Atacama Cosmology Telescope produced a catalog of 4,195 optically confirmed galaxy clusters detected via the Sunyaev-Zeldovich effect. The catalog includes 222 high-redshift clusters (z > 1), 868 new discoveries, and covers a sky area of 13,211 square degrees. It was created by NASA HEASARC and ingested in February 2021.
Observations from 2012-2013 with the VLA and ATCA radio telescopes surveyed sky areas around unassociated gamma-ray sources from the Fermi LAT Second Source Catalog. The survey identified 865 candidate radio sources and provided firm associations for 76 previously unknown gamma-ray active galactic nuclei (AGNs). This HEASARC table contains results from the survey, including follow-up observations with the VLBA and LBA.
A 2014 multi-epoch radio survey of the Kepler K2 mission's Field 1, covering 314 square degrees in the North Galactic Cap. The survey was conducted by NASA using the Murchison Widefield Array (MWA) and the Giant Metrewave Radio Telescope (GMRT) at frequencies between 140 and 200 MHz, producing catalogs with 1,085, 1,468, and 7,445 detections. It provides a resource for multi-wavelength study of over 21,000 K2 target objects.
178 low-redshift (0.2 < z < 0.3) optically selected quasars observed at 6 GHz with the Jansky Very Large Array. The table contains results from these observations, with 176 radio detections categorized into radio-loud and radio-quiet quasars. The data was created by NASA and last updated in March 2026.
More than 300 active galactic nuclei (AGN) up to redshift ~2.4, analyzed from the XMM-Newton Bright Serendipitous Survey.
