X-ray background

The observed X-ray background is thought to result from, below 0.3 keV, galactic X-ray emission, the galactic X-ray background, and, above 0.3 keV, from a combination of numerous X-ray point sources outside of the Milky Way, the cosmic X-ray background (CXB,^[1] XRB,^[2] CXRB^[3]).
