Density profiles of LCDM clusters
Argyro Tasitsiomi, Andrey V. Kravtsov, Stefan Gottloeber +1
We analyze the mass accretion histories (MAHs) and density profiles of cluster- size halos with virial masses of 0.6-2.5x10^14/h Msun in a flat LCDM cosmology. In agreement with pr…
The Dark Side of the Halo Occupation Distribution
Andrey V. Kravtsov, Andreas A. Berlind, Risa H. Wechsler +4
We analyze the halo occupation distribution (HOD), the probability for a halo of mass M to host a number of subhalos N, and two-point correlation function of galaxy-size dark matte…
Formation of globular clusters in hierarchical cosmology
Andrey V. Kravtsov, Oleg Y. Gnedin
We study the formation of globular clusters (GCs) in a Milky Way-size galaxy using a high-resolution cosmological simulation. The clusters in our model form in the dense cores of s…
Lensing Optical Depth for Substructure and Isolated Dark Matter Halos
Jacqueline Chen, Andrey V. Kravtsov, Charles R. Keeton
Multiply-imaged quasar lenses can be used to constrain the substructure mass fraction in galaxy-sized dark matter halos via anomalous flux ratios in lensed images. The flux ratios,…
