Kavli Affiliate: Mark Vogelsberger | Summary:The spatial extent of the environment’s impact on galaxies marks a transitional region between cluster and field galaxies. We present a data-driven method to identify this region in galaxy clusters with masses $M_200rm ,mean>10^13 M_odot$ at $z = 0$. Using resolved galaxy samples from the largest simulation volume of IllustrisTNG […]
