Abstract：Galaxy clusters are the largest gravitationally bound objects in the Universe and as such, they provide a host environment for testing both cosmology models and theories of galaxy evolution. In this talk, I will introduce the 300 galaxy cluster project, which includes over 300 galaxy clusters from a MultiDark simulation. These clusters regions (radius 15Mpc/h) are resimulated by different hydro-simulation codes. Further, we also have the cluster catalog in the same zoom-in regions from three different Semi-Analytical Models, which were run for the parent MultiDark simulation. I will also present some basic results from these catalogs.
