The ZCAT database contains the CfA Redshift Catalog, which incorporates much of the latest velocity data from the Whipple Observatory and other sources, as well as velocities...

This table contains results from the XMM-Newton Wide Angle Survey (XWAS), viz., a new catalog of almost a thousand X-ray sources that have been spectroscopically identified...

This database table is a catalog of all the RXTE slew observations and is based on information culled from the RXTE Data Archive's latest top-level FMI (FITS Master Index)...

The Rossi X-Ray Timing Explorer (RXTE) All-Sky Survey Slew Catalog contains the results of a serendipitous hard X-ray (3 - 20 keV), nearly all-sky (|b|>10 degrees) survey...

SkyView is a Virtual Observatory on the Net. Astronomers can generate images of any portion of the sky at wavelengths in all regimes from radio to gamma-ray. Users tell SkyView...

X-ray sources at intermediate fluxes (a few x 10^-14 erg/cm²/s) with a sky density of ~ 100 deg² are...

This database table contains the latest XMM-Newton XAssist source list. XAssist is a NASA-funded project for the automation of X-ray astrophysics, with emphasis on galaxies. It...

The X-ray variability of active galactic nuclei (AGN) has been most often investigated with studies of individual, nearby sources, and only a few ensemble analyses have been...

This table contains the results from a uniform, large-scale survey of X-ray flare emission, based on the XMM-Newton Serendipitous Source Catalog (2XMM) and its associated data...

The stacked catalog 4XMM-DR14s (<a href="/W3Browse/xmm-newton/xmmstack.html">XMMSTACK</a>) has been compiled from 1,751 groups, comprising 10,336 overlapping...

The stacked catalog 4XMM-DR14s has been compiled from 1,751 groups, comprising 10,336 overlapping XMM-Newton observations. They were selected from the public observations taken...

The authors have carried out a classification of 4,330 X-ray sources in the 2XMMi-DR3 catalog. The sources were selected under the requirement of being a point source with...

Many different classes of X-ray sources contribute to the Galactic landscape at high energies. Although the nature of the most luminous X-ray emitters is now fairly well...

The XMMSSC table contains the Fourth XMM-Newton Serendipitous Source Catalog, Fourteenth Data Release, or 4XMM-DR14. 4XMM-DR14 is the fourth-generation catalog of serendipitous...

This table contains the 'total' sample of sources from the second catalog of X-ray sources found in slew data taken by the European Space Agency's XMM-Newton...

The ongoing XMM-Newton Slew Survey (XSS) provides coverage of a significant fraction of the sky in a broad X-ray bandpass. Although shallow by contemporary standards, in the...
