A Splashback-like Feature of Central Galaxies in Galaxy Clusters
Yuanyuan Zhang, Susmita Adhikari, Louise O. V. Edwards +3
We investigate a splashback-like feature in the outer region of central galaxies (CGs) in clusters. This feature is detected as a "dip" in the radial slope of the CG surface bright…
