Faint Radio Active Galactic Nuclei

Chinese Journal of Astronomy and Astrophysics, 2005
To separate the faint radio AGN population and a population of star-forming galaxies and then to determine the properties of each population it is necessary to couple deep radio and optical observations over a reasonably large area of sky. Here we present the preliminary results obtained cross-matching the photometric VIMOS survey (Visible MultiObject ...

The kinetic luminosity of radio jets in active galactic nuclei

AIP Conference Proceedings, 2008
Based on the Konigl's inhomogeneous jet model, we estimate the jet parameters, such as bulk Lorentz factor Γ, viewing angle θ and electron number density ne from radio VLBI and X‐ray data for a sample of active galactic nuclei (AGNs). The kinetic luminosity of jets is then calculated using the derived jet parameters.

Monitoring Of Jets in Active Galactic Nuclei with VLBA Experiments. XVIII. Kinematics and Inner Jet Evolution of Bright Radio-loud Active Galaxies

Astrophysical Journal, 2021
We have analyzed the parsec-scale jet kinematics of 447 bright radio-loud active active galactic nuclei (AGN), based on 15 GHz Very Long Baseline Array (VLBA) data obtained between 1994 August 31 and 2019 August 4.

Dual active galactic nuclei from rainbows to radio

2022
Simulations of galactic mergers predict that tidally-induced gas inflows can trigger synchronized accretion onto the supermassive black holes at the center of each galaxy. These should be observable as dual active galactic nuclei (dAGN) at kpc-scale separations. We test this prediction using a carefully selected sample of 35 radio galaxy pairs from the
