Origin and Destiny of Dark Matter Halos: Cosmological Matter Exchange and Metal Enrichment
Tsafrir S. Kolatt, James S. Bullock, Avishai Dekel +4
[Abridged] We analyze the exchange of dark matter between halos, subhalos, and their environments in a high-resolution cosmological N-body simulation of a Lambda CDM cosmology. At…

Interaction rates of dark-matter halos and subhalos
Tsafrir S. Kolatt, James S. Bullock, Yair Sigad +4
[Abridged] The interaction rates of dark-matter halos and subhalos, are computed using high-resolution cosmological N-body simulations of the Lambda-CDM model. Although the number…

Velocity and Mass Functions of Galactic Halos: Evolution and Environmental Dependence
Yair Sigad, Tsafrir S. Kolatt, James S. Bullock +4
We study the distribution functions of mass and circular velocity for dark matter halos in N-body simulations of the CDM cosmology, addressing redshift and environmental depende…
