Description
Splashback radius is a physically motivated boundary of halos, formed at the first apocenters of orbiting matter. Due to its strong correlation to the recent mass accretion history, especially that over the last one dynamical time, the splashback radius could be used to study the cosmic evolution, as well as astrophysics within halos. In this talk, I will briefly summarize the recent progress on theories and observations of splashback radius, then present the (preliminary) result from the galaxy clusters detected by the eROSITA X-ray survey.
