Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stephanie O’Neil, Josh Borrow, Mark Vogelsberger, Benedikt Diemer, | Summary: We explore how the splashback radius ($R_{rm sp}$) of galaxy clusters, measured using the number density of the subhalo population, changes based on various selection criteria using the IllustrisTNG cosmological galaxy formation simulation. We identify $R_{rm sp}$ […]
