The origin of jets is one of the most important issues concerning active galactic nuclei, yet it has remained obscure. In this work, we made use of information from emission lines, spectral energy distributions, and Fermi–LAT γ-ray emission to construct a blazar sample that contains 667 sources. We note that jet power originations are different for BL Lacertae objects (BL Lacs) and flat-spectrum radio quasars (FSRQs). The correlation between jet power P jet and the normalized disk luminosity L… 

An Extensive Study of Blazar Broad Emission Line: Changing-look Blazars and the Baldwin Effect

It is known that the blazar jet emissions are dominated by nonthermal radiation, while the accretion disk jets are normally dominated by thermal emission. In this work, our aim is to study the



On the Jet Properties of γ-Ray-loud Active Galactic Nuclei

Based on broadband spectral energy distributions (SEDs), we estimate the jet physical parameters of 1392 γ-ray-loud active galactic nuclei (AGNs), the largest sample so far. The (SED) jet power and

The Central Engines of Fermi Blazars

We present a catalog of central engine properties, i.e., black hole mass (M BH) and accretion luminosity (L disk), for a sample of 1077 blazars detected with the Fermi Large Area Telescope. This

The relation between broad lines and γ-ray luminosities in Fermi blazars

We study the relation between the mass accretion rate, the jet power and the black hole mass of blazars. With this aim, we make use of the Sloan Digital Sky Survey and the 11-month catalogue of

The power of relativistic jets is larger than the luminosity of their accretion disks

An analysis of archival observations of a sample of blazars (quasars whose jets point towards Earth) that overcomes previous limitations finds a clear correlation between jet power, as measured through the γ-ray luminosity, and accretion luminosity; this implies that the magnetic field threading the black hole horizon reaches the maximum value sustainable by the accreting matter.

A Universal Scaling for the Energetics of Relativistic Jets from Black Hole Systems

It is shown that jets produced by AGN and GRBs exhibit the same correlation between the kinetic power carried by accelerated particles and the gamma-ray luminosity, which implies that the efficiency of energy dissipation in jets produced in black hole systems is similar over 10 orders of magnitude in jet power.

The Physical Properties of Fermi-4LAC Flat Spectrum Radio Quasars

In this work, we collect quasi-simultaneous infrared, optical, X-ray and γ-ray data of 60 Fermi fourth LAT AGN catalog (4LAC) flat spectrum radio quasars (FSRQs). In the framework of the conventional

The transition between BL Lac objects and flat spectrum radio quasars

We study the BL Lac objects detected in the one year all sky survey of the Fermi satellite, with a energy spectral slope α in the [0.1‐100 GeV] band greater than 1.2. In the α vs γ‐ray luminosity

Jet efficiencies and black hole spins in jetted quasars

The mechanisms responsible for the production of relativistic jets from supermassive black holes (SMBHs) accreting at near-Eddington rates are not well-understood. Simple theoretical expectations

Jets and accretion processes in active galactic nuclei: further clues

We present evidence in favour of a link between the luminosity radiatively dissipated in the central engine of radio-loud Active Galactic Nuclei and the kinetic power in their jets. This piece of

Doppler Factor Estimation for Fermi Blazars

In this work, we exploit the luminosity of the broad-line region (BLR) for 50 Fermi blazars through matching the coordinates between the Sloan Digital Sky Survey catalog, Fermi Large Area Telescope
