cosmic X-ray background

(CXB, CXRB, CXBR, cosmic X-ray background radiation)
(X-ray radiation coming from outside the Milky Way)

Cosmic X-ray background (CXB, CXRB, or CXBR) radiation is weak X-ray radiation detectable in many directions, apparently from outside the Milky Way. It is part of the cosmic background radiation.

It is presumed to come from faint, distant sources including, perhaps distant active galactic nuclei, an idea that has motivated research and some evidence has been cited.
