YZiCS: On the Mass Segregation of Galaxies in Clusters
Seonwoo Kim, Emanuele Contini, Hoseung Choi +5
Mass segregation, a tendency of more massive galaxies being distributed closer to the cluster center, is naturally expected from dynamical friction, but its presence is still contr…
The role of mergers and interactions in driving the evolution of dwarf galaxies over cosmic time
G. Martin, R. A. Jackson, S. Kaviraj +9
Dwarf galaxies (M*<10^9 Msun) are key drivers of mass assembly in high mass galaxies, but relatively little is understood about the assembly of dwarf galaxies themselves. Using the…
YZiCS: Unveiling Quenching History of Cluster Galaxies Using Phase-space Analysis
Jinsu Rhee, Rory Smith, Hoseung Choi +4
We used the time since infall (TSI) of galaxies, obtained from the Yonsei Zoom-in Cluster Simulation, and the star formation rate (SFR) from the Sloan Digital Sky Survey (SDSS) Dat…
New Horizon: On the origin of the stellar disk and spheroid of field galaxies at
Min-Jung Park, Sukyoung K. Yi, Yohan Dubois +7
The origin of the disk and spheroid of galaxies has been a key open question in understanding their morphology. Using the high-resolution cosmological simulation, New Horizon, we e…
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…
