We use a combination of three large N-body simulations to investigate the dependence of dark matter halo concentrations on halo mass and redshift in the Wilkinson Microwave Anisotropy Probe year 5…
The EAGLE project: Simulating the evolution and assembly of galaxies and their environments
- J. Schaye, R. Crain, J. Trayford
- Physics
- 25 July 2014
We introduce the Virgo Consortium's EAGLE project, a suite of hydrodynamical simulations that follow the formation of galaxies and black holes in representative volumes. We discuss the limitations of…
A Survey of z > 5.7 Quasars in the Sloan Digital Sky Survey. II. Discovery of Three Additional Quasars at z > 6
- X. Fan, M. Strauss, D. York
- Physics
- 8 January 2003
We present the discovery of three new quasars at z > 6 in ∼ 1300 deg2 of Sloan Digital Sky Survey imaging data, J114816.64+525150.3 (z = 6.43), J104845.05+463718.3 (z = 6.23), and J163033.90+401209.6…
The thermal history of the intergalactic medium
- J. Schaye, T. Theuns, M. Rauch, G. Efstathiou, W. Sargent
- Physics
- 20 December 1999
At redshifts z≳2, most of the baryons reside in the smooth intergalactic medium which is responsible for the low column density Lyα forest. This photoheated gas follows a tight temperature–density…
Model-independent Insights into the Nature of the Lyα Forest and the Distribution of Matter in the Universe
- J. Schaye
- Physics
- 17 April 2001
Straightforward physical arguments are used to derive the properties of Lyα forest absorbers. It is shown that many aspects of the current physical picture of the forest, in particular the fact that…
Metallicity of the Intergalactic Medium Using Pixel Statistics. II. The Distribution of Metals as Traced by C IV
- J. Schaye, A. Aguirre, Tae-Sun Kim, T. Theuns, M. Rauch, W. Sargent
- Physics
- 23 June 2003
We measure the distribution of carbon in the intergalactic medium as a function of redshift z and overdensity δ. Using a hydrodynamical simulation to link the H I absorption to the density and…
Simulating galactic outflows with kinetic supernova feedback
- C. D. Vecchia, J. Schaye
- Physics
- 18 January 2008
Feedback from star formation is thought to play a key role in the formation and evolution of galaxies, but its implementation in cosmological simulations is currently hampered by a lack of numerical…
Cosmological simulations of the growth of supermassive black holes and feedback from active galactic nuclei: method and tests
We present a method that self-consistently tracks the growth of supermassive black holes (BHs) and the feedback from active galactic nuclei (AGN) in cosmological, hydrodynamical simulations. Our…
Simulating galactic outflows with thermal supernova feedback
- C. D. Vecchia, J. Schaye
- Physics
- 26 March 2012
Cosmological simulations make use of sub-grid recipes for the implementation of galactic winds driven by massive stars because direct injection of supernova energy in thermal form leads to strong…
The EAGLE simulations of galaxy formation: calibration of subgrid physics and model variations
- R. Crain, J. Schaye, J. Trayford
- Physics
- 6 January 2015
We present results from thirteen cosmological simulations that explore the parameter space of the "Evolution and Assembly of GaLaxies and their Environments" (EAGLE) simulation project. Four of the…
