The excursion set model a step beyond: Environmental dependence
Nicos Hiotelis
In terms of the excursion set model, we used Monte Carlo methods in order to study the non-Markovian stochastic evolution of the smoothed overdensity at scale . For a Gaussi…
Mass functions from the excursion set model
Nicos Hiotelis, Antonino Del Popolo
Aims. We aim to study the stochastic evolution of the smoothed overdensity at scale of the form , where is a kernel and $\mathrm…
Merger rates of dark matter haloes: a comparison between EPS and N-body results
Nicos Hiotelis
We calculate merger rates of dark matter haloes using the Extended Press-Schechter approximation (EPS) for the Spherical Collapse (SC) and the Ellipsoidal Collapse (EC) models. Mer…
Merger rates of dark matter haloes from merger trees in the extended Press-Schechter theory
Nicos Hiotelis
We construct merger trees based on the extended Press-Schechter theory (EPS) in order to study the merger rates of dark matter haloes over a range of present day mass ($10^{10}M_{\…
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…
