A look into the inside of haloes: a characterization of the halo shape as a function of overdensity in the<i>Planck</i>cosmology

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 different distances from the halo centre (characterized by different overdensity thresholds), both in three and in two dimensions. We …
