| Abstract: |
The radio galaxy 3C 120 continues its pattern of low X-ray flux states preceding the appearance of superluminal knots in the radio jet. The rapid variability of the X-ray flux plus the presence of an iron line indicate that the main source of X-ray emission is the accretion disk/corona. A plausible cause of the X-ray dips is a decrease in the viscosity during episodes of enhanced poloidal magnetic field. The same condition could divert extra energy into the jet, causing a shock to propagate downstream, eventually appearing as a superluminal feature. |
