Journal ArticleDOI

Energy input from quasars regulates the growth and activity of black holes and their host galaxies

Tiziana Di Matteo, +2 more
- 10 Feb 2005 - 
TL;DR: Simulations that simultaneously follow star formation and the growth of black holes during galaxy–galaxy collisions find that, in addition to generating a burst of star formation, a merger leads to strong inflows that feed gas to the supermassive black hole and thereby power the quasar.
Journal ArticleDOI

Modelling feedback from stars and black holes in galaxy mergers

Volker Springel, +2 more
- 11 Aug 2005 - 
TL;DR: In this paper, a coarse-grained representation of the properties of the interstellar medium (ISM) and BH accretion starting from basic physical assumptions is proposed to incorporate feedback from star formation and black hole accretion into simulations of isolated and merging galaxies.

Modeling feedback from stars and black holes in galaxy mergers

Volker Springel, +2 more
- 04 Nov 2004 - 
TL;DR: In this paper, a coarse-grained representation of the properties of the interstellar medium and black hole accretion starting from basic physical assumptions is proposed, and the impact of these effects can be included on resolved scales.
Journal ArticleDOI

A Unified, Merger-driven Model of the Origin of Starbursts, Quasars, the Cosmic X-Ray Background, Supermassive Black Holes, and Galaxy Spheroids

Philip F. Hopkins, +5 more
- 01 Mar 2006 - 
TL;DR: In this article, an evolutionary model for starbursts, quasars, and spheroidal galaxies is presented, in which mergers between gas-rich galaxies drive nuclear inflows of gas, producing starburst and feeding the buried growth of supermassive black holes (BHs) until feedback expels gas and renders a briefly visible optical quasar.

TL;DR: In this article, the authors present an evolutionary model for starbursts, quasars, and spheroidal galaxies, in which mergers between gas-rich galaxies drive nuclear inflows of gas, producing intense starburst and feeding the buried growth of supermassive black holes (BHs) until feedback expels gas and renders a briefly visible optical quasar.
