Quasars and Galaxy Formation
Joseph Silk, Martin J. Rees
TL;DR
This paper explores how quasars and their energetic outflows influence galaxy formation, particularly the relationship between supermassive black holes and galaxy spheroids, impacting our understanding of galaxy evolution.
Contribution
It derives a new relation between black hole mass and galaxy spheroid mass, highlighting the role of quasars in galaxy formation processes.
Findings
Black hole mass correlates with galaxy spheroid mass.
Quasar outflows significantly impact protogalactic star formation.
Implications for galaxy formation scenarios are discussed.
Abstract
The formation of massive black holes may precede the epoch that characterises the peak of galaxy formation, as characterized by the star formation history in luminous galaxies. Hence protogalactic star formation may be profoundly affected by quasar-like nuclei and their associated extensive energetic outflows. We derive a relation between the mass of the central supermassive black hole and that of the galaxy spheroidal component, and comment on other implications for galaxy formation scenarios.
