The Role of Pre-Processing in Tidal Feature Formation within Galaxy Clusters
Kyungwon Chun, Jihye Shin, Jongwan Ko +3
We investigate the formation of tidal features, such as tidal tails, streams, and shell-like structures, composed of stars stripped from satellites within galaxy clusters. For this…
Dynamical Evolution of Substructured Star Clusters at 3 kpc from the Galactic Center
So-Myoung Park, Jihye Shin, Sang-Hyun Chun +3
We investigate the evolution of initial fractal clusters at 3 kpc from the Galactic Center (GC) of the Milky Way and show how red supergiant clusters (RSGCs)-like objects, which ar…
Galaxy Quenching with Mass Growth History of Galaxy Groups and Clusters: The Importance of Post-Processing
So-Myoung Park, Kyungwon Chun, Jihye Shin +5
We investigate the fraction of quenched satellite galaxies in host galaxy groups and clusters using TNG300 in the IllustrisTNG cosmological magnetohydrodynamical simulations. Simul…
Making top-heavy IMFs from canonical IMFs near the Galactic Centre
So-Myoung Park, Simon P. Goodwin, Sungsoo S. Kim
We show that dynamical evolution in a strong (Galactic Centre-like) tidal field can create clusters that would appear to have very top-heavy IMFs. The tidal disruption of single st…
The early dynamical evolution of star clusters near the Galactic Centre
So-Myoung Park, Simon P. Goodwin, Sungsoo S. Kim
We examine the dynamical evolution of both Plummer sphere and substructured (fractal) star forming regions in Galactic Centre (GC) strong tidal fields to see what initial condition…
