Mock galaxy redshift catalogues from simulations: implications for Pan-STARRS1
Yan-Chuan Cai, Raul E. Angulo, Carlton M. Baugh +3
We describe a method for constructing mock galaxy catalogues which are well suited for use in conjunction with large photometric surveys. We use the semi-analytic galaxy formation…
Towards accurate modelling of the ISW effect, the non-linear contribution
Yan-Chuan Cai, Shaun Cole, Adrian Jenkins +1
In a universe with a cosmological constant, the large-scale gravitational potential varies in time and this is, in principle, observable. Using an N-body simulation of a CDM uni…
The Colours of Satellite Galaxies in Groups and Clusters
Andreea S. Font, Richard G. Bower, Ian G. McCarthy +6
Current models of galaxy formation predict satellite galaxies in groups and clusters that are redder than observed. We investigate the effect on the colours of satellite galaxies p…
The redshift dependence of the structure of massive LCDM halos
Liang Gao, Julio F. Navarro, Shaun Cole +5
(Abridged) We use two very large cosmological simulations to study how the density profiles of relaxed LCDM dark halos depend on redshift and on halo mass. We confirm that these pr…
The statistical properties of LCDM halo formation
Shaun Cole, John Helly, Carlos S. Frenk +1
We present a comparison of the statistical properties of dark matter halo merger trees extracted from the Millennium Simulation with Extended Press-Schechter (EPS) formalism and th…
Constraints on sigma_8 from galaxy clustering in N-body simulations and semi-analytic models
Geraint Harker, Shaun Cole, Adrian Jenkins
We generate mock galaxy catalogues for a grid of different cosmologies, using rescaled N-body simulations in tandem with a semi-analytic model run using consistent parameters. Beca…
Generating Dark Matter Halo Merger Trees
Hannah Parkinson, Shaun Cole, John Helly
We present a new Monte-Carlo algorithm to generate merger trees describing the formation history of dark matter halos. The algorithm is a modification of the algorithm of Cole et a…
The statistics of LCDM Halo Concentrations
Angelo F. Neto, Liang Gao, Philip Bett +6
We use the Millennium Simulation (MS) to study the statistics of LCDM halo concentrations at z = 0. Our results confirm that the average halo concentration declines monotonically w…
Measuring the Baryon Acoustic Oscillation scale using the SDSS and 2dFGRS
Will J. Percival, Shaun Cole, Daniel J. Eisenstein +4
We introduce a method to constrain general cosmological models using Baryon Acoustic Oscillation (BAO) distance measurements from galaxy samples covering different redshift ranges,…
The Galaxy Power Spectrum: 2dFGRS-SDSS tension?
Shaun Cole, Ariel G. Sanchez, Stephen Wilkins
Published galaxy power spectra from the 2dFGRS and SDSS are not in good agreement. We revisit this issue by analyzing both the 2dFGRS and SDSS DR5 catalogues using essentially iden…
Satellite Systems around Galaxies in Hydrodynamic Simulations
Noam I Libeskind, Shaun Cole, Carlos S Frenk +2
We investigate the properties of satellite galaxies formed in N-body/SPH simulations of galaxy formation in the CDM cosmology. The simulations include the main physical effects…
The Effect of Gravitational Recoil on Black Holes Forming in a Hierarchical Universe
N. I. Libeskind, S. Cole, C. S. Frenk +1
Galactic bulges are known to harbour central black holes whose mass is tightly correlated with the stellar mass and velocity dispersion of the bulge. In a hierarchical universe, me…
The broken hierarchy of galaxy formation
R. G. Bower, A. J. Benson, R. Malbon +5
Recent observations of the distant Universe suggest that much of the stellar mass of bright galaxies was already in place at . This presents a challenge for models of galaxy f…
Galaxy Groups in the 2dFGRS: the number density of groups
V. R. Eke, C. M. Baugh, S. Cole +2
The abundance of galaxy clusters as a function of mass is determined using the 2dFGRS Percolation-Inferred Galaxy Group (2PIGG) catalogue. This is used to estimate the amplitude of…
A marked correlation function analysis of halo formation times in the Millennium Simulation
Geraint Harker, Shaun Cole, John Helly +2
We study the environmental dependence of the formation epoch of dark matter haloes in the Millennium Simulation: a ten billion particle N-body simulation of standard LambdaCDM cosm…
The 2dF Galaxy Redshift Survey: correlation with the ROSAT-ESO Flux Limited X-ray (REFLEX) galaxy cluster survey
Matt Hilton, Chris Collins, Roberto De Propris +25
The ROSAT-ESO Flux Limited X-ray (REFLEX) galaxy cluster survey and the 2dF Galaxy Redshift Survey (2dFGRS) respectively comprise the largest, homogeneous X-ray selected cluster ca…
Cosmological parameters from CMB measurements and the final 2dFGRS power spectrum
Ariel G. Sanchez, C. M. Baugh, W. J. Percival +5
We derive constraints on cosmological parameters using the power spectrum of galaxy clustering measured from the final two-degree field galaxy redshift survey (2dFGRS) and a compil…
Simulating the joint evolution of quasars, galaxies and their large-scale distribution
Volker Springel, Simon D. M. White, Adrian Jenkins +14
The cold dark matter model has become the leading theoretical paradigm for the formation of structure in the Universe. Together with the theory of cosmic inflation, this model make…
The metal enrichment of elliptical galaxies in hierarchical galaxy formation models
Masahiro Nagashima, Cedric G. Lacey, Takashi Okamoto +3
We investigate the metal enrichment of elliptical galaxies in the framework of hierarchical models of galaxy formation. The semi-analytical model we use in this Letter, which has b…
The Distribution of Satellite Galaxies: The Great Pancake
Noam I Libeskind, Carlos S Frenk, Shaun Cole +4
The 11 known satellite galaxies within 250 kpc of the Milky Way lie close to a great circle on the sky. We use high resolution N-body simulations of galactic dark matter halos to t…
