The jets-accretion relation, mass-luminosity relation in Fermi blazars

TL;DR

This study analyzes a sample of 111 Fermi blazars to explore the relationships between jet power, accretion, and black hole mass, revealing correlations that support theoretical models of jet production and a mass-luminosity relation similar to stars.

Contribution

It provides the first comprehensive analysis of the jet-accretion and mass-luminosity relations in Fermi blazars, confirming theoretical predictions and proposing an evolutionary sequence.

Findings

Significant correlation between radio core and broad-line luminosities.

The jet power is linked to black hole spin and accretion disk magnetic fields.

The mass-luminosity relation follows a power-law similar to main-sequence stars.

Abstract

A sample of 111 Fermi blazars each with a well-established radio core luminosity, broad-line luminosity, bolometric luminosity and black hole mass has been compiled from the literatures.We present a significant correlation between radio core and broad-line emission luminosities that supports a close link between accretion processes and relativistic jets. Analysis reveals a relationship of $\rm{LogL_{BLR}\sim(0.81\pm0.06)LogL_{R}^{C}}$ which is consistant with theoretical predicted coefficient and supports that blazar jets are powered by energy extraction from a rapidly spinning Kerr black hole through the magnetic field provided by the accretion disk. Through studying the correlation between the intrinsic bolometric luminosity and the black hole mass, we find a relationship of $\rm{{Log}\frac{L_{in}}{L_{\odot}}=(0.95\pm0.26){Log}\frac{M}{M_{\odot}}+(3.53\pm2.24)}$ which supports mass-luminosity relation for Fermi blazars derived in this work is a powerlaw relation similar to that for main-sequence stars. Finally, evolutionary sequence of blazars is discussed.
