We use a series of cosmological N-body simulations for a flat A cold dark matter (ACDM) cosmology to investigate the structural properties of dark matter haloes, at redshift zero, in the mass range 3 x 10 9 h -1 ≤ M vir ≤ 3 x 10 13 h -1 M ⊙ . These properties include the concentration parameter, c, the spin parameter, λ, and the mean axis ratio, q. For the concentration-mass relation we find c oc M -0.11 vir agreement with the model proposed by Bullock et al., but inconsistent with the… 
Dark-matter-dominated cluster-scale halos act as an important cosmological probe and provide a key testing ground for structure formation theory. Focusing on their mass profiles, we have carried out
Concentration, spin and shape of dark matter haloes as a function of the cosmological model: WMAP1, WMAP3 and WMAP5 results
We investigate the effects of changes in the cosmological parameters between the Wilkinson Microwave Anisotropy Probe (WMAP) 1st, 3rd and 5th year results on the structure of dark matter haloes. We
The redshift dependence of the structure of massive Λ cold dark matter haloes
We use two very large cosmological simulations to study how the density profiles of relaxedCDM dark halos depend on redshift and on halo mass. We confirm that these profiles deviate slightly but
Are mergers responsible for universal halo properties
N-body simulations of cold dark matter (CDM) have shown that, in this hierarchical structure formation model, dark matter halo properties, such as the density profile, the phase-space density
A mass-dependent density profile for dark matter haloes including the influence of galaxy formation
ABSTRACT We introduce a mass dependent density profile to describe the distribution of dark matterwithin galaxies, which takes into account the stellar-to-halo mass dependence of the responseof dark
The mass–concentration–redshift relation of cold and warm dark matter haloes
We use a suite of cosmological simulations to study the mass–concentration–redshift relation, c(M, z), of dark matter haloes. Our simulations include standard Λ-cold dark matter (CDM) models, and
The accretion history of dark matter haloes - III. A physical model for the concentration-mass relation
We present a semi-analytic, physically motivated model for dark matter halo concentration as a function of halo mass and redshift. The semi-analytic model is intimately based on hierarchical
The inner structure of haloes in cold+warm dark matter models
We analyze the properties of dark matter halos in the cold-plus-warm dark matter cosmologies (CWDM). We study their dependence on the fraction and velocity dispersion of the warm particle, keeping
The evolution of dark matter halo properties in clusters, filaments, sheets and voids
We use a series of high-resolution N-body simulations of the concordance cosmology to investigate the redshift evolution since z = 1 of the properties and alignment with the large-scale structure
Understanding the halo-mass and galaxy-mass cross-correlation functions
We use the Millennium Simulation (MS) to measure the cross-correlation between halo centres and mass (or equivalently the average density profiles of dark haloes) in a Lambda cold dark matter (ACDM)


The shape of dark matter haloes : dependence on mass, redshift, radius and formation
Using six high-resolution dissipationless simulations with a varying box size in a flat Lambda cold dark matter (ACDM) universe, we study the mass and redshift dependence of dark matter halo shapes
Profiles of dark haloes: evolution, scatter and environment
We study dark-matter halo density profiles in a high-resolution N-body simulation of aCDM cosmology. Our statistical sample contains �5000 haloes in the range 10 11 10 14 h −1 M⊙ and the resolution
The Power Spectrum Dependence of Dark Matter Halo Concentrations
High-resolution N-body simulations are used to examine the power spectrum dependence of the concentration of galaxy-sized dark matter halos. It is found that dark halo concentrations depend on the
Mass and redshift dependence of dark halo structure
Using a combination of N-body simulations with different resolutions, we study in detail how the concentrations of cold dark matter halos depend on halo mass at different redshifts. We confirm that
We study properties of dark matter halos at high redshifts z ¼ 2-10 for a vast range of masses with the emphasis on dwarf halos with masses of 10 7 -10 9 h � 1 M� . We find that the density profiles
Assembly bias in the clustering of dark matter haloes
We use a very large simulation of structure growth in a Λ cold dark matter (ΛCDM) universe – the Millennium Simulation – to study assembly bias, the fact that the large-scale clustering of haloes of

A series of high-resolution ΛCDM cosmological N-body simulations are used to study the properties of galaxy-size dark halos as a function of global environment. We analyze halos in three types of

Statistics of Physical Properties of Dark Matter Clusters
We have identified over 2000 well-resolved cluster halos, and also their associated bound subhalos, from the output of a 10243 particle cosmological N-body simulation (of box size 320 h-1 Mpc and
