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…
Measuring the Nonlinear Biasing Function from a Galaxy Redshift Survey
Yair Sigad, Enzo Branchini, Avishai Dekel
We present a simple method for evaluating the nonlinear biasing function of galaxies from a redshift survey. The nonlinear biasing is characterized by the conditional mean of the g…
Profiles of dark haloes: evolution, scatter, and environment
James S. Bullock, Tsafrir S. Kolatt, Yair Sigad +5
We study dark-matter halo density profiles in a high-resolution N-body simulation of an LCDM cosmology. Our statistical sample contains ~5000 haloes in the range 10^{11}-10^{14} M_…
Young galaxies: what turns them on?
Tsafrir S. Kolatt, James S. Bullock, Rachel S. Somerville +8
Lyman break galaxies (LBGs) at exhibit number densities and clustering similar to local galaxies; however, their star formation rates (SFRs) are much higher. We ex…
