TL;DR: The XMM-Newton Medium Sensitivity Survey (XMS) as mentioned in this paper consists of four largely overlapping source samples selected at soft (0.5-2 keV), intermediate (0.,5-4.5 keV) and hard (2-10 keV).
Detection of type-2 quasars in the radio galaxies B3 0731+438 and 3C 257
TL;DR: In this article, XMM-Newton observations and spectral fitting of two highly redshift, [OIII]-luminous, narrow-line radio galaxies, B3 0731+438 and 3C 257, are presented.
