The Preferential Tidal Stripping of Dark Matter versus Stars in Galaxies
Rory Smith, Hoseung Choi, Jaehyun Lee +3
Using high resolution hydrodynamical cosmological simulations, we conduct a comprehensive study of how tidal stripping removes dark matter and stars from galaxies. We find that dar…
The SAMI galaxy survey: Galaxy Interactions and Kinematic Anomalies in Abell 119
Sree Oh, Sukyoung K. Yi, Luca Cortese +25
Galaxy mergers are important events that can determine the fate of a galaxy by changing its morphology, star-formation activity and mass growth. Merger systems have commonly been i…
Recent galaxy mergers and residual star formation of red sequence galaxies in galaxy clusters
Yun-Kyeong Sheen, Sukyoung K. Yi, Chang H. Ree +3
This study explored the GALEX ultraviolet (UV) properties of optical red sequence galaxies in 4 rich Abell clusters at z \leq 0.1. In particular, we tried to find a hint of merger-…
The Demographics of galactic bulges in the SDSS database
Keunho Kim, Sree Oh, Hyunjin Jeong +3
We present a new database of our two-dimensional bulge-disk decompositions for 14,233 galaxies drawn from SDSS DR12 in order to examine the properties of bulges residing in the loc…
Sussing Merger Trees: Stability and Convergence
Yang Wang, Frazer R. Pearce, Alexander Knebe +15
Merger trees are routinely used to follow the growth and merging history of dark matter haloes and subhaloes in simulations of cosmic structure formation. Srisawat et al. (2013) co…
Galaxy Luminosity Function of Dynamically Young Abell 119 Cluster: Probing the Cluster Assembly
Youngdae Lee, Soo-Chang Rey, Michael Hilker +2
We present the galaxy luminosity function (LF) of the Abell 119 cluster down to mag based on deep images in the -, -, and -bands taken by using MOSAIC II CCD…
