Study of inner jet of blazars

Abstract

Process of extraction of jet energy Blazars(AGN) is the best experimental source of highly luminous 훾-ray jets. It can be investigated through the Blandford-Znajek(BZ) process, where sources are observed on average 훾-ray luminosity through Fermi-LAT over 11 months of operations. Since most Blazars belong to elliptical galaxies and numbers of stars in galaxies are roughly the same, hence the effect of gravity on central SMBH will be mass-dependent, which should be related to their spin parameter(angular momentum) and based on the rotation of accreting plasma in the accretion disk, the strength of developed magnetic fields (called force-free magnetosphere) should also be spin-dependent and hence finally mass-dependent. Through the BZ process, Blazars spin parameter and magnetic fields can be estimated as a mass-dependent function. Ultimately, a phase-space of mass and luminosity can be traced for these sources, where all the sources are constrained by minimum and maximum boundary of luminosity.
