3D Genus Topology of Luminous Red Galaxies
J. Richard Gott, Yun-Young Choi, Changbom Park +1
We measure the 3D genus topology of large scale structure using Luminous Red Galaxies (LRGs) in the Sloan Digital Sky Survey and find it consistent with the Gaussian random phase i…
Alignments of Group Galaxies with Neighboring Groups
Yougang Wang, Changbom Park, Xiaohu Yang +2
Using a sample of galaxy groups found in the Sloan Digital Sky Survey Data Release 4, we measure the following four types of alignment signals: (1) the alignment between the distri…
Combined Effects of Galaxy Interactions and Large-Scale Environment on Galaxy Properties
Changbom Park, Yun-Young Choi
We inspect the coupled dependence of physical parameters of the SDSS galaxies on the small-scale (distance to and morphology of the nearest neighbor galaxy) and the large-scale (ba…
The nature of the SDSS galaxies in various classes based on morphology, colour and spectral features -- I. Optical properties
Joon Hyeop Lee, Myung Gyoon Lee, Changbom Park +1
We present a comprehensive study of the nature of the SDSS galaxies divided into various classes based on their morphology, colour, and spectral features. The SDSS galaxies are cla…
Galactic Satellite Systems: Radial Distribution and Environment Dependence of Galaxy Morphology
H. B. Ann, Changbom Park, Yun-Young Choi
We have studied the radial distribution of the early (E/S0) and late (S/Irr) types of satellites around bright host galaxies. We made a volume-limited sample of 4,986 satellites br…
A Subhalo-Galaxy Correspondence Model of Galaxy Formation
Juhan Kim, Changbom Park, Yun-Young Choi
We propose a model of allocating galaxies in cosmological N-body simulations. we identify each subhalo with a galaxy, and assign luminosity and morphological type assuming that the…
