Tidal Stripping and Post-Merger Relaxation of Dark Matter Halos: Causes and Consequences of Mass Loss

Christoph T. Lee, Joel R. Primack, Peter Behroozi +3

We study the properties of distinct dark matter halos (i.e., those that are not subhalos) that have a final virial mass $M_{\mathrm{vir}}$ at $z=0$ less than their peak mass ($M_…
