X-ray emission from a radio hot spot in 3C 390.3: evidence for the deflection of a radio jet by a neighboring galaxy

摘要

By summing a large number of ROSAT High Resolution Imager (HRI) observations of the variable radio galaxy 3C 390.3, we demonstrate that the X-ray emission associated with the northern radio lobe(reported by Prieto) can be identified with hot sport B. None of the other hot spots have been detected. We present evidence That the anomalous X-ray emission is the consequence of a strong shock produced where the northern radio jet Impinges onto an external galaxy.
