Seyfert Galaxies: X Rays
Scientific paper
Extended X-ray emission has been found around the nuclei of 5 Seyfert galaxies with the ROSAT HRI. The extended emission is typically ≡kpc in spatial extent, has luminosity ≡1040-42erg s-1 and aligns with the radio and/or ENLR axis. The extent of the X-ray emission is very similar to that of the extended optical line emitting gas. If the extended X-rays are interpreted as thermal emission, the pressure of the hot gas is similar to that of both the gas at 104K and the radio synchrotron emitting electrons plus magnetic field. The hot gas may be associated with an outflowing wind or may represent gas entrained and shocked by the radio ejecta or jets.
