On the jet properties of the gamma-ray loud active galactic nuclei [HEAP]

http://arxiv.org/abs/1803.05715


Based on broadband SEDs, we estimate jet physical parameters of 1392 $\gamma$-ray loud active galactic nuclei (AGNs), the largest sample so far. The (SED) jet power and magnetization parameter are derived for these AGNs. Out of these sources, accretion disk luminosity of 232 sources and (extended) kinetic jet powers of 159 sources are compiled from archived papers. We find, 1) FSRQs and BL Lacs are well separated by $\Gamma=-0.127\log L_{\gamma}+8.18$, in $\gamma$-ray luminosity versus photon index plane, with a succuss rate 88.6\%. 2) Most FSRQs present the (SED) jet power larger than accretion power, which suggests that the relativistic jet launching mechanism is dominated by the Blandford-Znajek process. This result confirms previous finding. 3) We find a significant anti-correlation between jet magnetization and a ratio of the (SED) jet power to the (extended) kinetic jet power, which, for the first time, provides supporting evidence for jet energy transportation theory: high magnetization jet may be more easily to transport energy to large scale than low magnetization jet.
