On the reliability of merger-trees and the mass growth histories of dark matter haloes
N. Hiotelis, A. Del Popolo
We have used merger trees realizations to study the formation of dark matter haloes. The construction of merger-trees is based on three different pictures about the formation of st…
Extended Press-Schechter theory and the density profiles of dark matter haloes
Nicos Hiotelis
An inside-out model for the formation of haloes in a hierarchical clustering scenario is studied. The method combines the picture of the spherical infall model and a modification o…
Density profiles in a spherical infall model with non-radial motions
Nicos Hiotelis
A generalized version of the Spherical Infall Model (SIM) is used to study the effect of angular momentum on the final density profile of a spherical structure. The numerical metho…
The velocity field of collapsing spherical structures. Limitations of the spherical infall model in mass estimation
Nicos Hiotelis
We assume that the amplitude of the caustics in redshift space is a sum of two components: the first one can be predicted by the spherical infall model with no random motion, and t…
