Model for the X-ray emission in the jets and hot spots of radio galaxies.

We propose a model for the origin of extended X-ray emission in the largescale jets and hot spots of radio galaxies. If radio galaxies are misaligned blazars, then they are sources of collimated high-energy gamma radiation from the inner jet. Gamma rays with ≥ 100 TeV energies will be attenuated by the microwave background and surrounding radiation fields, causing high-energy electrons and pairs to be injected far from the central engine. The high-energy pairs will produce X-ray synchrotron radiation that could account for the emission detected from sources such as Pictor A and Cygnus A with the Chandra X-ray Observatory.
