The relationship among XBLs, RBLs and FSRQs

摘要

In this work, we revisited the relationship between the subclasses of blazars (Xray selected BL Lacertae objects (XBLs), radio selected BL Lacertae objects (RBLs), and flat spectrum radio quasars (FSRQs)) based on a sample of blazars. We found that the FSRQsRBLsXBLs relationship is clear in their bolometric luminosity, emission line luminosity and the accretion ratio with V_(FSRQs) > V_(RBLs) > V_(XBLs), where V stands for the three parameters. However, there is no clear difference amongst their central black hole masses. The bolometric luminosity is closely correlated with the emission line luminosity and the accretion ratio.
