Investigating the Disk-corona Relation in Radio-quiet and Radio-Ioud AGNs

摘要：

We compile a blue AGN sample with 240 radio-quiet (RQ) and 18 radio loud (RL) objects. We investigate the dependence of ratio of hard X-ray luminosity to bolometric luminosity on black hole mass and Eddington ratio. We find that the hard X-ray fraction log(L2_lOOkev/Lbol) decreases with the increase of Eddington ratio for RQ AGNs, which is not the case for RL AGNs. We also find that the hard X-ray fraction is independent on black hole mass for both RQ and RL AGNs. The implication is discussed in the end of the poster.
