Relating the Structure of Dark Matter Halos to Their Assembly and Environment

We use a large N -body simulation to study the relation of the structural properties of dark matter halos to their assembly history and environment. The complexity of individual halo assembly histories can be well described by a small number of principal components (PCs), which, compared to formatio...
