Almost all galaxies host in their center a supermassive black hole of mass between a million and tens of billions solar masses. Supermassive black holes grow in symbiosis with their host galaxies across the Hubble time, occasionally accreting surround matter, giving rise to an Active Galactic Nuclei (AGN). This book gives a general review of our current knowledge of AGN, powered by supermassive black holes: how they are fueled by gas (or stars) and what problems are encountered; how can we account for the wide variety of AGN, from Seyfert/Liners to quasars, and for the two types (AGN 1 and 2) either through dust obscuration, and geometrical orientation arguments, or through intrinsic activity difference, qualitative or quantitative. With modern instruments, providing high resolution and sensitivity, like ALMA in radio, or MUSE at the ESO/VLT, it is possible to unveil the interstellar medium and stars in the circumnuclear regions, discover molecular disks and tori, in the sphere of influence of the black holes. While AGN are accreting matter, they are providing so much energy that part of the surrounding gas is expelled and is observed in molecular outflows, identified as the main feedback process of AGN on their host.

Key Features:

Reviews our current knowledge of AGN, with case studies and examples of observed AGN in their host galaxies.

Discusses the long-standing problem of AGN fueling and feedback, and proposes educated models of the circum-nuclear regions, which are still difficult to resolve.

Covers recent advances in the field of AGN research provided by current astronomical instrumentation (e.g., ALMA, VLT).

Written by a world-leading expert in the field.

Reviews for Active Galactic Nuclei: Fueling and feedback

The field of active galactic nuclei (AGN) is rapidly evolving. Starting from the properties of the central engine in the 1960s, it now includes topics like the mutual interaction between black holes (BHs) and their host galaxies, the parallel evolution of BHs and galaxies, BH formation, and more. It is therefore justified to devote an entire five-chapter book to describe only one or two aspects of this large area of research. This is the intention of the new book by Françoise Combes, a well-known expert in the field, who chose to devote her book to fuelling and feedback in AGN. The feeding and feedback parts clearly justify the writing of the book. They are full of useful up-to-date information including many colour illustrations that help readers find their way in this complex and rather messy area of research.
