Impact of Galaxy Mergers on Stellar Population Profiles of Early-type Galaxies
Yongmin Yoon, Jongwan Ko, Jae-Woo Kim
We study the impact of galaxy mergers on stellar population profiles/gradients of early-type galaxies (ETGs) using ETGs at in the Stripe 82 region of the Sloan Digital Sk…
Performance Assessment of the KASI-Deep Rolling Imaging Fast-optics Telescope pathfinder
Woowon Byun, Jongwan Ko, Yunjong Kim +14
In a CDM universe, most galaxies evolve by mergers and accretions, leaving faint and/or diffuse structures, such as tidal streams and stellar halos. Although these structures ar…
The First Fall is the Hardest: The Importance of Peculiar Galaxy Dynamics at Infall Time for Tidal Stripping Acting at the Centers of Groups and Clusters
Rory Smith, Paula Calderon-Castillo, Jihye Shin +2
Using dark matter only N-body cosmological simulations, we measure the pericentre distance of dark matter halos on their first infall into group and cluster halos. We find that the…
Tracing Recent Star Formation of Red Early-type Galaxies out to 1
Jongwan Ko, Ho Seong Hwang, Myungshin Im +3
We study the mid-infrared (IR) excess emission of early-type galaxies (ETGs) on the red-sequence at 1 using a spectroscopic sample of galaxies in the fields of Great Observat…
Measurable Relationship Between Bright Galaxies and Their Faint Companions in WHL J085910.0+294957, a Galaxy Cluster at z = 0.30: Vestiges of Infallen Groups?
Joon Hyeop Lee, Hye-Ran Lee, Minjin Kim +8
The properties of satellite galaxies are closely related to their host galaxies in galaxy groups. In cluster environments, on the other hand, the interaction between close neighbor…
