Journal ArticleDOI
Density profiles of dark matter haloes: diversity and dependence on environment
Vladimir Avila-Reese,Vladimir Avila-Reese,C. Firmani,C. Firmani,Anatoly Klypin,Andrey V. Kravtsov +5 more
TL;DR: In this article, the outer density profiles of dark matter haloes predicted by a generalized secondary infall model and observed in a dissipationless cosmological simulation of a low-density flat cold dark matter model with the Cosmological constant were studied.
Journal ArticleDOI
The fossil phase in the life of a galaxy group
Alexander M. von Benda-Beckmann,Elena D'Onghia,Stefan Gottlöber,Matthias Hoeft,A. Khalatyan,Anatoly Klypin,Volker Müller +6 more
TL;DR: In this paper, the authors investigate the origin and evolution of fossil groups in a concordance ACDM cosmological simulation, and study the physical mechanisms that lead to the formation of the large gap in magnitude between the brightest and the second most bright group member.
Journal ArticleDOI
The coma cluster after lunch: Has a galaxcy group passed through the cluster core?
TL;DR: In this article, a new Hydro/N-body simulation of the merger between a galaxy group and a rich cluster that reproduces many of the observed X-ray and optical properties of Coma/NGC 4839 is presented.
Journal ArticleDOI
The emptiness of voids: yet another overabundance problem for the Λ cold dark matter model
Anton V. Tikhonov,Anatoly Klypin +1 more
TL;DR: In this paper, the luminosity function, the peculiar velocities and the sizes of voids in the Local Volume (LV) in observational samples of galaxies which contain galaxies down to M B = −10 and −12 within the distance 4-8 Mpc.
Journal ArticleDOI
Cold dark matter variant cosmological models — I. Simulations and preliminary comparisons
Michael A. K. Gross,Michael A. K. Gross,Rachel S. Somerville,Rachel S. Somerville,Joel R. Primack,Jon A. Holtzman,Anatoly Klypin +6 more
TL;DR: In this article, two matched sets of five dissipationless simulations each, including four presently favored minimal modifications to the standard cold dark matter (CDM) scenario, were presented.
