A 200 KS ASCA OBSERVATION OF THE BROAD IRON LINE IN THE RADIO GALAXY 3C120
ABSTRACT
We propose to observe the radio galaxy 3C120 to see any similarities and/or differences in the line profile from those of Seyfert 1 galaxies and to see whether or not the broad, skewed, profile of the iron line is really emission from matter within a few Schwarzschild radii of a black hole. According the previous ASCA observation of this source, we will be able to have a line profile with the same quality as that of MCG-6-30-15 by a 200 ks observation. From a constraint on the inclination angle of jets of this source given by the superluminal motion, we will be able to discuss the origin of the line profile in terms of the diks-line model. At the same time, it might be possible to see changes of the innermost accretion disk associated with the jet-activity.
