Journal ArticleDOI
The mass function dependence on the dynamical state of dark matter haloes
R. Seppi,Johan Comparat,Kirpal Nandra,Esra Bulbul,Francisco Prada,Anatoly Klypin,Anatoly Klypin,Andrea Merloni,Peter Predehl,J. Ider Chitham +9 more
TL;DR: In this article, a generalized mass function framework was proposed to account for the dynamical state of the dark matter haloes in the galaxy clusters, which is key toward precision cosmology using galaxy counts as a probe.

Halo Abundance Matching: accuracy and conditions for numerical convergence
TL;DR: In this article, the authors investigate the accuracy of one of the leading methods of connecting the simulated dark matter haloes with observed galaxies, the Halo Abundance Matching (HAM) technique.
Journal ArticleDOI
Profiles of dark haloes: evolution, scatter, and environment
James S. Bullock,James S. Bullock,Tsafrir S. Kolatt,Yair Sigad,Rachel S. Somerville,Rachel S. Somerville,Andrey V. Kravtsov,Andrey V. Kravtsov,Anatoly Klypin,Joel R. Primack,Avishai Dekel +10 more
TL;DR: In this paper, the authors studied dark-matter halo density profiles in a high-resolution N-body simulation of an LCDM cosmology, and they found that for a given halo mass, the redshift dependence of the median concentration is c_v ~ 1/(1+z), corresponding to a roughly constant r_s with redshift.
Journal ArticleDOI
Evolution of Clusters in Cold Plus Hot Dark Matter Models
Charles Walter,Anatoly Klypin +1 more
TL;DR: In this paper, the authors used N-body simulations to study evolution of galaxy clusters over the redshift interval 0 <= z <= 0.5 in cosmological models with a mixture of cold and hot dark matter (CHDM).
Journal ArticleDOI
The Anisotropic Distribution of Galactic Satellites
TL;DR: In this article, the authors present a study of the spatial distribution of subhalos in galactic dark matter halos using dissipationless cosmological simulations of the concordance LCDM model.
