YZiCS: Preprocessing of dark halos in the hydrodynamic zoom-in simulation of clusters

San Han, Rory Smith, Hoseung Choi +4

To understand the galaxy population in clusters today, we should also consider the impact of previous environments prior to cluster infall, namely preprocessing. We use YZiCS, a hy…

On the origin of gas-poor galaxies in galaxy clusters using cosmological hydrodynamic simulations

Seoyoung L. Jung, Hoseung Choi, O. Ivy Wong +3

The environmental effect is commonly used to explain the excess of gas-poor galaxies in galaxy clusters. Meanwhile, the presence of gas-poor galaxies at cluster outskirts, where ga…
