Abstract:
In this work, we compile a sample of 449 Fermi blazars with the
luminosity of the broadline region, the black hole mass, the beam
radio luminosity, and the jet power; obtain the beam power and the
black hole spin; investigate the dividing line between BL Lacertae
objects (BL Lacs) and flat-spectrum radio quasars (FSRQs) to identify
the discrepancies in their dominant mechanisms; and revisit the
dependence of the jet power on the disk accretion luminosity, the
black hole mass, and the black hole spin. We come to the following
conclusions. (1) A boundary of log (LBLR/LEdd)=-3.14, separating the
BL Lacs and the FSRQs, is obtained from the Bayesian analysis, which
is consistent with the results from the literature. We employ the
boundary to divide the blazar candidates of uncertain types into
candidates for BL Lacs or FSRQs, and we find five changing-look
blazars at the same time. (2) A strong correlation is found between
black hole mass and intrinsic γ-ray luminosity, but a weaker
correlation is found between black hole mass and observed γ-ray
luminosity. The latter is weakened by jet effects: it is apparently
weak for BL Lacs that have disordered amplification of the Doppler
factor, since their mechanism is dominated by jets, while it is
moderate for FSRQs, since their mechanism is dominated by accretion
processes. (3) The jets of both FSRQs and BL Lacs are likely governed
by the Blandford-Znajek mechanism.
Description:
In this paper, a large sample of 449 Fermi blazars with available BLR
luminosities and black hole masses are compiled.
