Extended and compact X-ray emission in powerful radio galaxies
Abstract
We report ROSAT X-ray observations of two powerful radio galaxies. 3C 280 provides evidence for a mixture of unresolved and extended emission, with the latter produced by hot plasma of insufficient pressure to confine the radio lobes and insufficient density for a cooling flow to have begun. 3C 220.3 gives only an X-ray upper limit, but one consistent with our interpretation of the X-ray emission from powerful radio-loud active galactic nuclei (AGNs) in terms of obscured and unobscured components.
