英文摘要 | We have analysed a large sample of clean blazars detected by Fermi Large Area Telescope (LAT). Using the literature and calculation, we obtained intrinsic gamma-ray luminosity excluding beaming effect, black hole mass, broad-line luminosity (used as a proxy for disc luminosity), jet kinetic power from 'cavity' power and bulk Lorentz factor for parsec-scale radio emission, and studied the distributions of these parameters and relations between them. Our main results are as follows. (i) After excluding beaming effect and redshift effect, intrinsic gamma-ray luminosity with broad-line luminosity, black hole mass and Eddington ratio have significant correlations. Our results confirm the physical distinction between BL Lacs and FSRQs. (ii) The correlation between broad-line luminosity and jet power is significant which supports that jet power has a close link with accretion. Jet power depends on both the Eddington ratio and black hole mass. We also obtain logL(BLR) similar to (0.98 +/- A 0.07)logP(jet) for all blazars, which is consistent with the theoretical predicted coefficient. These results support that jets are powered by energy extraction from both accretion and black hole spin (i.e. not by accretion only). (iii) For almost all BL Lacs, P-jet > L-disc; for most of FSRQs, P-jet < L-disc. The 'jet-dominance' (parametrized as P-jet/L-disc) is mainly controlled by the bolometric luminosity. Finally, the radiative efficiency of gamma-ray and properties of TeV blazars detected by Fermi LAT were discussed. |
