Abstract:
Using N-body cosmological simulation, we present a detail study of redshift evolution
and the impact of box size on the properties of dark matter halos. Our focus is to review
their structural parameters in ΛCDM model. We aim to study the effects of angular
momentum in dark matter halos using tidal torque theory. Using arguments based on
the spherical collapse model, we analyze the behaviour of the scalelength of density
profiles of dark matter. We predicted the mass distribution of dark matter halos using
the Tinker et al. mass function. We also investigated the redshift dependence of halo
mass, concentration, viral energy ratios, offset of density peaks and spin parameter. We
utilized different computational packages for analysis and found our statistical results
in agreement with the findings of previous studies.
