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…
Wobbling galaxy spin axes in dense environments
Jaehyun Lee, Suk Kim, Hyunjin Jeong +7
The orientation of galaxy spin vectors within the large scale structure has been considered an important test of our understanding of structure formation. We investigate the angula…
Early-type galaxy spin evolution in the Horizon-AGN simulation
Hoseung Choi, Sukyoung K. Yi, Yohan Dubois +3
Using the Horizon-AGN simulation data, we study the relative role of mergers and environmental effects in shaping the spin of early-type galaxies (ETGs) after . We foll…
