Journal ArticleDOI
From dwarf spheroidals to cD galaxies: simulating the galaxy population in a ΛCDM cosmology
Qi Guo,Simon D. M. White,Michael Boylan-Kolchin,Gabriella De Lucia,Guinevere Kauffmann,Gerard Lemson,Cheng Li,Volker Springel,Simone M. Weinmann +8 more
TL;DR: In this paper, a semi-analytic galaxy formation model was proposed and applied to the stored halo/subhalo merger trees of the Millennium and Millennium-II simulations, allowing explicit testing of resolution effects on predicted galaxy properties.
Journal ArticleDOI
From dwarf spheroidals to cDs: Simulating the galaxy population in a LCDM cosmology
Qi Guo,Simon D. M. White,Michael Boylan-Kolchin,Gabriella De Lucia,Guinevere Kauffmann,Gerard Lemson,Cheng Li,Volker Springel,Simone M. Weinmann +8 more
TL;DR: In this article, the authors apply semi-analytic galaxy formation models simultaneously to the stored halo/subhalo merger trees of the Millennium and Millennium-II simulations, allowing explicit testing of resolution effects on predicted galaxy properties.
Journal ArticleDOI
Resolving cosmic structure formation with the Millennium-II simulation
TL;DR: The Millennium-II Simulation (MS-II) as mentioned in this paper is a very large N-body simulation of dark matter evolution in the concordance A cold dark matter (ACDM) cosmology.
Journal ArticleDOI
Galaxy formation in the Planck cosmology – I. Matching the observed evolution of star formation rates, colours and stellar masses
Bruno M. B. Henriques,Simon D. M. White,Peter A. Thomas,Raul E. Angulo,Qi Guo,Gerard Lemson,Volker Springel,Volker Springel,Roderik Overzier +8 more
TL;DR: In this paper, the Munich galaxy formation model was updated to the Planck first-year cosmology, while modifying the treatment of baryonic processes to reproduce recent data on the abundance and passive fractions of galaxies from z = 3 down to z = 0.
Journal ArticleDOI
The EAGLE simulations of galaxy formation: Public release of halo and galaxy catalogues
Stuart McAlpine,John C. Helly,Matthieu Schaller,James W. Trayford,Yan Qu,Michelle Furlong,Richard G. Bower,Robert A. Crain,Joop Schaye,Tom Theuns,C. Dalla Vecchia,C. Dalla Vecchia,Carlos S.

TL;DR: A relational database storing a large number of properties of haloes and galaxies and their merger trees, including stellar masses, star formation rates, metallicities, photometric measurements and mock gri images is made available for general use.
