Abstract
Imaging x-ray observations of a complete sample of 3CR radio galaxies led to the detection of 26 of them with (0.5–3.0 keV) Lx ∼10 41-10 45 erg s −1. A statistical analysis of the sample, in conjunction with radio and optical data reveals that nuclear activity is likely to be responsible for most of the x-ray emission. Moreover we find that the 3CR emission line galaxies are similar to both Seyfert galaxies and quasars with double radio morphology in their x-ray properties, strongly reinforcing an unified picture of active nuclei. The properties of double radio sources and flat spectrum quasars however differ. The non-emission line galaxies (like 3C264) are also likely to contain a nuclear x-ray source.
