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 ...

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

High energy neutrinos from radio-quiet active galactic nuclei

Physical Review D, 2004
Most active galactic nuclei (AGN) lack prominent jets, and show modest radio emission and significant x-ray emission which arises mainly from the galactic core, very near the central black hole. We use a quantitative scenario of such core-dominated radio-quiet AGN, which attributes a substantial fraction of the x-ray emission to the presence of ...

11.17. Radio emission from low-luminosity active galactic nuclei

Symposium - International Astronomical Union, 1998
“Low-luminosity” active galactic nuclei (LLAGNs) typically have ≳ mag, as opposed to −18 to −30 mag for luminous Seyfert 1 nuclei and QSOs. The physical origin of the class of emission-line nuclei known as low-ionization nuclear emission-line regions (LINERs; Heckman 1980) remains controversial.
