Radio Loudness of Active Galactic Nuclei: Observational Facts and Theoretical Implications [PDF]
The Astrophysical Journal, 2007 We investigate how the total radio luminosity of AGN-powered radio sources depends on their accretion luminosity and the central black hole mass. Our studies cover about seven orders of magnitude in accretion luminosity and the full range of AGN black hole masses. We find that AGNs form two distinct and well separated sequences on the radio-loudness --

Galaxy Evolution in the Radio Band: The Role of Star-forming Galaxies and Active Galactic Nuclei [PDF]
, 2017 We investigate the astrophysics of radio-emitting star-forming galaxies and active galactic nuclei (AGNs) and elucidate their statistical properties in the radio band, including luminosity functions, redshift distributions, and number counts at sub-mJy ...

THE CONTRIBUTION OF ACTIVE GALACTIC NUCLEI TO THE MICROJANSKY RADIO POPULATION [PDF]
The Astrophysical Journal, 2009 A X-ray background synthesis model is used to calculate the contribution of Active Galactic Nuclei (AGNs) to the 1.4 GHz number counts between 100 nJy and 10 mJy. The number counts are broken down into contributions from radio-quiet and radio-loud AGNs, obscured and unobscured AGNs, and for different ranges in redshift and 2-10 keV X-ray luminosity ...

The Role of Active Galactic Nuclei in the Quenching of Massive Galaxies in the SQuIGG E Survey [PDF]
Astrophysical Journal, 2020 We study the incidence of nuclear activity in a large sample of massive post-starburst (PSB) galaxies at selected from the Sloan Digital Sky Survey, and identify active galactic nuclei based on radio continuum and optical emission lines.

The many lives of active galactic nuclei: cooling flows, black holes and the luminosities and colour [PDF]
, 2005 We simulate the growth of galaxies and their central supermassive black holes by implementing a suite of semi-analytic models on the output of the Millennium Run, a very large simulation of the concordance A cold dark matter cosmogony.

Observational Tests of Active Galactic Nuclei Feedback: An Overview of Approaches and Interpretation [PDF]
GalaxiesGrowing supermassive black holes (Active Galactic Nuclei; AGN) release energy with the potential to alter their host galaxies and larger-scale environment; a process named “AGN feedback”.
