Formation of Dark Matter Halos
J. R. Primack, J. S. Bullock, A. A. Klypin +1
This article concerns the formation and structure of dark matter halos, including (1) their radial density profiles, (2) their abundance, and (3) their merger rates. The last topic…
Halo evolution in a cosmological environment
S. Gottloeber, A. A. Klypin, A. V. Kravtsov
We study the formation and evolution of the dark matter halos in a LCDM model. The dynamics of 16.8 million DM particles is followed numerically in a box of 60 Mpc/h with the dynam…
Evolution of isolated halos and halos inside of groups and clusters in a LCDM model
Stefan Gottloeber, Anatoly Klypin, Andrey Kravtsov
A significant fraction of mass in the universe is believed to be in the form of dark matter (DM). Due to gravitational instability, the DM collapses hierarchically into DM halos. I…
Evolution of halo-halo clustering and bias in a LCDM model
Andrey Kravtsov, Anatoly Klypin, Pedro Colin +1
We study the evolution of the halo-halo correlation function and bias in a LCDM model using very high-resolution N-body simulations. The high force and mass resolution allows dark…
