Release of data from high-resolution cosmological N-body simulations
P. Colin, A. Klypin
We make available to the public 4 dark matter simulations that cover 4 CDM cosmological models and were run with the AP^3M code (Couchamn 1991). These simulations are described in…
Spatial and Velocity Biases
Anatoly Klypin, Andrey V. Kravtsov, Pedro Colin
We give a summary of our recent studies of spatial and velocity biases of galaxy-size halos in cosmological models. Recent progress in numerical techniques made it possible to simu…
The evolution of groups and clusters
S. Gottloeber, A. Klypin, A. V. Kravtsov +1
Using high resolution N-body simulations we have studied the formation and evolution of clusters and groups in a LCDM cosmological model. Groups of galaxies have been formed alread…
Merging Rate of Dark Matter Halos: Evolution and Dependence on Environment
Stefan Gottloeber, Anatoly Klypin, Andrey V. Kravtsov
We discuss the impact of the cosmological environment on the evolution of dark matter halos using a high-resolution simulation within a spatially flat LCDM cosmology.
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_…
Velocity bias in a LCDM model
Pedro Colin, Anatoly Klypin, Andrey V. Kravtsov
We use N-body simulations to study the velocity bias of dark matter halos, the difference in the velocity fields of dark matter and halos, in a flat low- density LCDM model. The hi…
Density profiles of dark matter haloes: diversity and dependence on environment
V. Avila-Reese, C. Firmani, A. Klypin +1
(Abridged) We study the outer density profiles of dark matter haloes predicted by a generalized secondary infall model and observed in a N-body cosmological simulation of a ΛCDM mo…
Quantifying the evolution of higher-order clustering
Jens Schmalzing, Stefan Gottloeber, Anatoly A. Klypin +1
We use a high-resolution dissipationless simulation to study the evolution of the dark matter and halo distributions in a spatially flat cosmological model dominated by a cosmologi…
The Santa Barbara cluster comparison project: a comparison of cosmological hydrodynamics solutions
C. S. Frenk, S. D. M. White, P. Bode +22
We have simulated the formation of an X-ray cluster in a cold dark matter universe using 12 different codes. The codes span the range of numerical techniques and implementations cu…
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…
