Simulations of the formation, evolution and clustering of galaxies and quasars
Volker Springel,Simon D. M. White,Adrian Jenkins,Carlos S. Frenk,Naoki Yoshida,Liang Gao,Julio F. Navarro,Robert J. Thacker,Darren J. Croton,John C. Helly,John A. Peacock,Shaun Cole,Peter A. Thomas,Hugh M. P. Couchman,August E. Evrard,Jörg M. Colberg,Frazers Pearce +16 more
TL;DR: It is shown that baryon-induced features in the initial conditions of the Universe are reflected in distorted form in the low-redshift galaxy distribution, an effect that can be used to constrain the nature of dark energy with future generations of observational surveys of galaxies.
Journal ArticleDOI
The EAGLE project: Simulating the evolution and assembly of galaxies and their environments
Joop Schaye,Robert A. Crain,Richard G. Bower,Michelle Furlong,Matthieu Schaller,Tom Theuns,Tom Theuns,Claudio Dalla Vecchia,Claudio Dalla Vecchia,Carlos S. Frenk,Ian G. McCarthy,John C.

Trayford +24 more
TL;DR: The Virgo Consortium's EAGLE project as discussed by the authors is a suite of hydrodynamical simulations that follow the formation of galaxies and black holes in representative volumes, where thermal energy is injected into the gas, allowing winds to develop without predetermined speed or mass loading factors.
Journal ArticleDOI
Breaking the hierarchy of galaxy formation
Richard G. Bower,Andrew J. Benson,Rowena K. Malbon,John C. Helly,Carlos S. Frenk,Carlton M. Baugh,Shaun Cole,Cedric G. Lacey +7 more
TL;DR: In this paper, a new implementation of the Durham semi-analytic model of galaxy formation in which feedback due to active galactic nuclei (AGN) is assumed to quench cooling flows in massive halos is discussed.
