Halo mass function and scale-dependent bias from N-body simulations with non-Gaussian initial conditions
Annalisa Pillepich, Cristiano Porciani, Oliver Hahn
We perform a series of high-resolution N-body simulations of cosmological structure formation starting from Gaussian and non-Gaussian initial conditions. We adopt the best-fitting…
The Aspen--Amsterdam Void Finder Comparison Project
Joerg M. Colberg, Frazer Pearce, Caroline Foster +16
Despite a history that dates back at least a quarter of a century studies of voids in the large--scale structure of the Universe are bedevilled by a major problem: there exist a la…
Tidal Effects and the Environment Dependence of Halo Assembly
Oliver Hahn, Cristiano Porciani, Avishai Dekel +1
We explore a possible origin for the puzzling anti-correlation between the formation epoch of galactic dark-matter haloes and their environment density. This correlation has been r…
The Evolution of Dark Matter Halo Properties in Clusters, Filaments, Sheets and Voids
Oliver Hahn, C. Marcella Carollo, Cristiano Porciani +1
We use a series of N-body simulations of the LCDM cosmology to investigate the redshift evolution since z=1 of the properties and alignment with the large-scale structure of haloes…
Properties of Dark Matter Haloes in Clusters, Filaments, Sheets and Voids
Oliver Hahn, Cristiano Porciani, C. Marcella Carollo +1
Using a series of high-resolution N-body simulations of the concordance cosmology we investigate how the formation histories, shapes and angular momenta of dark-matter haloes depen…
