Cosmological evolution of supermassive black holes and AGN: a synthesis model for accretion and feedback
Andrea Merloni
The growth of supermassive black holes (SMBH) through accretion is accompanied by the release of enormous amounts of energy which can either be radiated away, as happens in quasars…
Measuring the kinetic power of AGN in the radio mode
Andrea Merloni, Sebastian Heinz
(Abridged) We have studied the relationship among nuclear radio and X-ray power, Bondi rate and the kinetic luminosity of sub-Eddington active galactic nuclear (AGN) jets. Besides…
The fundamental plane of black hole activity and the census of the local black holes' population
Andrea Merloni
Studying a sample of both strongly and weakly active galactic nuclei with measured masses and 5 GHz and 2-10 keV core luminosities, together with a few galactic black holes simulta…
Modes of disc accretion onto black holes
A. Merloni
I review our current theoretical understanding of the different possible rotating modes of accretion onto a black hole. I discuss both thick adiabatic flows and radiatively efficie…
Microquasars in the low/hard state: strong coronae, compact jets, and the high frequency variability
A. Merloni
We apply a model of magnetically dominated coronae above standard accretion discs to the low/hard state of galactic black holes. When the disc-corona coupling is accounted for self…
