A look to the inside of haloes: a characterisation of the halo shape as a function of overdensity in the Planck cosmology
Giulia Despali, Carlo Giocoli, Mario Bonamigo +2
In this paper we study the triaxial properties of dark matter haloes of a wide range of masses extracted from a set of cosmological N-body simulations. We measure the shape at diff…
The universality of the virial halo mass function and models for non-universality of other halo definitions
Giulia Despali, Carlo Giocoli, Raul E. Angulo +4
The abundance of galaxy clusters can constrain both the geometry and growth of structure in our Universe. However, this probe could be significantly complicated by recent claims of…
Cosmology through arc statistics I: sensitivity to and
Michele Boldrin, Carlo Giocoli, Massimo Meneghetti +3
The next generation of large sky photometric surveys will finally be able to use arc statistics as a cosmological probe. Here we present the first of a series of papers on this top…
Some like it triaxial: the universality of dark matter halo shapes and their evolution along the cosmic time
Giulia Despali, Carlo Giocoli, Giuseppe Tormen
We present a detailed analysis of dark matter halo shapes, studying how the distributions of ellipticity, prolateness and axial ratios evolve as a function of time and mass. With t…
Ellipsoidal halo finders and implications for models of triaxial halo formation
Giulia Despali, Giuseppe Tormen, Ravi K. Sheth
We describe an algorithm for identifying ellipsoidal haloes in numerical simulations, and quantify how the resulting estimates of halo mass and shape differ with respect to spheric…
Formation times, mass growth histories and concentrations of dark matter haloes
Carlo Giocoli, Giuseppe Tormen, Ravi K. Sheth
We develop a simple model for estimating the mass growth histories of dark matter halos. The model is based on a fit to the formation time distribution, where formation is defined…
