A new sample of 4299 galaxies with X-ray emission was obtained in this work by cross-correlating 2XMM catalog of X-ray sources with HyperLeda database of galaxies. We analyzed distributions of optical and X-ray fluxes, redshifts and X-ray luminosities for this sample. Virgo and Coma galaxy clusters can be easily detected at redshift-space distribution of X-ray galaxies. X-ray luminosity function of our galaxies shows the evidences of cosmological evolution, even at low redshifts.

The Xgal Catalog of X-Ray Galaxies

One of the mainstreams in modern X-ray astronomy is research into extragalactic X-ray sources on the basis of the data acquired at the X-ray Multi-Mirror Newton (XMM-Newton) space observatory.
