Abstract

We have analyzed a large sample of Flat Spectrum Radio Quasars (FSRQs) detected by Fermi Large Area Telescope (Fermi LAT). Our main intents are to investigate the relation between accretion rate and multi-wavelength luminosity and between black hole mass and multi-wavelength luminosity. Our results are as follows: There is significant correlation between accretion rate and multi-wavelength luminosity, which supports that jet formation have a close link with accretion. The significant correlations between black hole mass and multi-wavelength luminosity may imply that there is a close relation between faster jets and more massive black holes.
