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,
from beyond the Milky Way.
By definition, it constitutes part of the cosmic background radiation (CBR).
It is presumed to come from faint, distant sources
including, perhaps distant active galactic nuclei (AGNs),
a theory that has motivated research and some evidence
has been cited.
