TL;DR
This paper reviews how supermassive black holes influence galaxy formation and evolution by releasing energy that can suppress star formation, affecting the development of different galaxy types.
Contribution
It explores the impact of black hole energy output on galaxy evolution, highlighting the role of active galactic nuclei in regulating star formation.
Findings
Black hole energy can heat and eject gas, suppressing star formation.
Active galactic nuclei are key in the transition from star-forming to quiescent galaxies.
Black hole feedback is crucial in the evolution of elliptical galaxies.
Abstract
Virtually all massive galaxies, including our own, host central black holes ranging in mass from millions to billions of solar masses. The growth of these black holes releases vast amounts of energy that powers quasars and other weaker active galactic nuclei. A tiny fraction of this energy, if absorbed by the host galaxy, could halt star formation by heating and ejecting ambient gas. A central question in galaxy evolution is the degree to which this process has caused the decline of star formation in large elliptical galaxies, which typically have little cold gas and few young stars, unlike spiral galaxies.
