New radio-galaxy X-ray results from Chandra

Abstract

The superior spatial resolution of the Chandra X-ray Observatory is sharpening our X-ray vision of extragalactic radio sources. Our recent Guest Observer observations of a small sample of B2 radio galaxies show jet X-ray emission to be common in low-power radio galaxies, whereas previously such jets were only X-ray detected in nearby Cen A and M 87. At high redshift, Chandra clearly separates AGN-related emission from the surrounding X-ray emitting cluster medium, as illustrated by our results for 3C 220.1 at a redshift of 0.6.
