Description
Many universal yet simple laws have been discovered describing the distributions of subhalos, including their initial and final mass functions and spatial distributions. Validating the fidelity of these laws against numerical effects and extending them to different cosmologies require physical understanding of their origins. In this talk, I will introduce an extremely simple idea to unify the understanding of these universal laws, assuming that subhalo progenitors are accreted unbiasedly from the surrounding environment. I will also introduce the extension of subhalo distribution laws to different cosmologies, different dark matter species and different levels of subhalos, and respond to recent challenges on artificial disruptions of subhalos according to our physical understanding of subhalo evolution.
