The Dependence of the Mass Assembly History of Cold Dark Matter Halos on Environment
C. Maulbetsch, V. Avila-Reese, P. Colin +3
We show by means of a high-resolution N-body simulation how the mass assembly histories of galaxy-size cold dark matter (CDM) halos depend on environment. Halos in high density env…
Microlensing in the double quasar SBS1520+530
E. R. Gaynullina, R. W. Schmidt, T. Akhunov +7
We present the results of a monitoring campaign of the double quasar SBS1520+530 at Maidanak observatory from April 2003 to August 2004. We obtained light curves in V and R filters…
Dwarf Dark Matter Halos
P. Colin, A. Klypin, O. Valenzuela +1
We study properties of dark matter halos at high redshifts z=2-10 for a vast range of masses with the emphasis on dwarf halos with masses 10^7-10^9 Msun/h. We find that the density…
Galaxies in N-body simulations: overcoming the overmerging problem
Anatoly Klypin, Stefan Gottloeber, Andrey Kravtsov +1
We present analysis of the evolution of dark matter halos in dense environments of groups and clusters in dissipationless cosmological simulations. The premature destruction of hal…
