Halo evolution in a cosmological environment
TL;DR: In this paper, the authors studied the formation and evolution of the dark matter halos in a LCDM model and showed that the mass evolution of isolated virialized objects determined from the simulation is in good agreement with predictions of the extended Press-Schechter models.
Journal ArticleDOI
The evolution of groups and clusters
TL;DR: In this paper, the formation and evolution of clusters and groups in a ΛCDM cosmological model is studied. But the model is not suitable for high-resolution N-body simulations.
High-Resolution Simulations of Clusters of Galaxies
Daisuke Nagai,Andrey V. Kravtsov +1 more
TL;DR: Using very high-resolution Adaptive Mesh Refinement (AMR) gasdynamics simulations of clusters forming in the CDM universes, the authors investigated structural evolution of the intracluster gas and the role of dynamical (e.g., mergers) and physical processes operating during cluster evolution.

Supersonic Motions of Galaxies in Clusters
Andreas Faltenbacher,Andreas Faltenbacher,Andrey V. Kravtsov,Daisuke Nagai,Stefan Gottloeber +4 more
TL;DR: In this article, the authors studied the motions of galaxies in galaxy clusters formed in the concordance LCDM cosmology and found that galaxies, on average, move supersonically with the average Mach number of ~1.4, approximately independent of the cluster-centric radius.

Cold Dark Matter Substructure and Galactic Disks II: Dynamical Effects of Hierarchical Satellite Accretion
Stelios Kazantzidis,Andrew R. Zentner,Andrey V. Kravtsov,James S. Bullock,Victor P. Debattista +4 more
TL;DR: In this paper, a dissipationless N-body simulation was performed to elucidate the dynamical response of thin disks to bombardment by cold dark matter (CDM) substructure.
