De. Harris et al., X-RAY-EMISSION FROM A RADIO HOT-SPOT IN 3C-390.3 - EVIDENCE FOR THE DEFLECTION OF A RADIO JET BY A NEIGHBORING GALAXY, The Astrophysical journal, 499(2), 1998, pp. 149-152
By summing a large number of ROSAT High Resolution Imager (HRI) observ
ations of the variable radio galaxy 3C 390.3, we demonstrate that the
X-ray emission associated with the northern radio lobe (reported by Pr
ieto) can be identified with hot spot B. None of the other hot spots h
ave been detected. We present evidence that the anomalous X-ray emissi
on is the consequence of a strong shock produced where the northern ra
dio jet impinges onto an external galaxy.
