Title
On the Track of Universality in Cosmic Structures
Abstract
Our cosmic neighbourhood is richly structured by galaxies, clusters, and larger objects which are mainly composed of dark matter. Gravitationally bound objects dominated by dark matter exhibit density profiles which are self-similar over many orders of magnitude in mass. Why is this so? I will use kinetic field theory to address this question, and show that cosmic structures develop universal correlations for wide classes of initial conditions.
