Broad line and multi-wave luminosity relations in Fermi FSRQs

We study broad line and multi-wave luminosity relations for 80 flat-spectrum radio quasars (FSRQs) detected by Fermi LAT. Our results are as follows: for FSRQs, the correlations between logL _γ and logL _BLR, between logL _X and logL _BLR, between logL _O and logL _BLR, between logL _R and logL _BLR are significant; the correlation between logL _IR and logL _BLR (P=0.08) is not significant, but might be refereed as a “trend” of significant correlation. These results support a close link between jet formation and accretion disk, and the L _γ -L _BLR correlation suggests that the radiation mechanism of the γ-ray emission in FSRQs is likely to be inverse Compton scattering of seed photons from BLR or outflowing BLR.
