Abstract:
The correlation between the kinetic jet power Pjet, intrinsic
γ-ray luminosity (Lint), and accretion (Ldisc) may reveal
the underlying jet physics in various black hole systems. We study the
relation between kinetic jet power, intrinsic γ-ray luminosity, and
accretion by using a large sample of jetted active galactic nuclei
(AGNs), including flat-spectrum radio quasars (FSRQs), BL Lacertae
objects (BL Lacs), γ-ray narrow-line Seyfert 1 galaxies
(γNLS1s), and radio galaxies. Our main results are as follows:
(1) The slope indices of the relation between Pjet and Lint are
0.85 ± 0.01 for the whole sample, 0.70 ± 0.02 for the FSRQs,
0.83 ± 0.03 for the BL Lacs, 0.68 ± 0.11 for the γNLS1s, and
0.93 ± 0.09 for the radio galaxies, respectively. The jets in
γNLS1s and radio galaxies almost follow the same Pjet - Lint
correlation that was obtained for Fermi blazars. (2) The slope indices
of the relation between Lint and Ldisc are 1.05 ± 0.02 for the whole
sample, 0.94 ± 0.05 for the FSRQs, 1.14 ± 0.05 for the BL Lacs,
and 0.92 ± 0.18 for the γNLS1s, respectively. The γNLS1s
and radio galaxies almost also follow the Lint-Ldisc correlation
derived for Fermi blazars. (3) The jet power is larger than the
luminosity of accretion discs for almost all jetted AGNs. Jet power
depends on both the Eddington ratio and black hole mass. We obtain
logPjet ∼ (1.00 ± 0.02)logLdisc for the whole sample, which is
consistent with the theoretically predicted coefficient. These results
may imply that the jets of jetted AGNs are powered by the
Blandford-Znajek mechanism.
Description:
Blazars are a special subclass of active galactic nuclei (AGNs) whose
relativistic jets point towards the observer. According to the
equivalent width (EW) of the broad emission lines, blazars are divided
into two subclasses: flat-spectrum radio quasars (FSRQs) and BL
Lacertae objects (BL Lacs). Since the successful launch of the Fermi
telescope, many sources have detected high-energy γ-ray
emissions, such as blazars, radio galaxies, and RLNLS1s which implies
that these supermassive black hole with γ-ray emissions has
strong relativistic jets. Previously, the properties of Fermi blazars
have been studied based on a small sample. However, there have been
questions such as what the relationship between Fermi blazars, radio
galaxies, and RLNLS1 is? What is the jet formation mechanism of these
jetted AGNs? Do they have similar jet properties? There has been a
lack of research on this issue with a large sample.
In this work, we use a large sample of γ-ray sources including
blazars, radio galaxies, and RLNLS1s to study the properties of their
jets. We used Paliya et al. (2021ApJS..253...46P 2021ApJS..253...46P, Cat. J/ApJS/253/46),
Abdollahi et al. (2020ApJS..247...33A 2020ApJS..247...33A, Cat. J/ApJS/247/33) and Ajello
et al. (2020ApJ...892..105A 2020ApJ...892..105A , Cat. J/ApJ/892/105) which are works
mainly based on Fermi LAT DR2 and SDSS DR16 survey. With relations
described in section 2 and 3, we computed logMBH, logLblr, logLint and
logPjet for our selected 837 objects comprising 504 FSRQs, 277 BL
Lacs, and 17 γNLS1s (sources with verified optical spectrum and
F1.4GHz values). Results are presented in table1.dat.
