Constructing a Galaxy Cluster Catalog in IllustrisTNG300 Using the Mulguisin Algorithm Open
We present a new simulated galaxy cluster catalog based on the IllustrisTNG simulation. We use the Mulguisin (MGS) algorithm to identify galaxy overdensities. Our cluster identification differs from the previous friends-of-friends (FoF) cl…
