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...

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 third 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...

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

The authors have compiled a sample of X-ray-selected galaxy groups and clusters from the XMM-Newton Serendipitous Source Catalog (2XMMi-DR3) with optical confirmation and...
