Interactions of Galaxies in the Galaxy Cluster Environment
Changbom Park, Ho Seong Hwang
We study the dependence of galaxy properties on the clustercentric radius and the environment attributed to the nearest neighbor galaxy using the SDSS galaxies associated with the…
Washington CCD Photometry of the Globular Cluster System of the Giant Elliptical Galaxy M60 in Virgo
Myung Gyoon Lee, Hong Soo Park, Eunhyeuk Kim +3
We present a photometric study of the globular clusters in the giant elliptical galaxy M60 in the Virgo cluster, based on deep, relatively wide field Washington CT_1 CCD images. Th…
Galaxy Orbits for Galaxy Clusters in Sloan Digital Sky Survey and 2dF Galaxy Redshift Survey
Ho Seong Hwang, Myung Gyoon Lee
We present the results of a study for galaxy orbits in galaxy clusters using a spectroscopic sample of galaxies in Sloan Digital Sky Survey (SDSS) and 2dF Galaxy Redshift Survey (2…
Wide-Field Survey of Globular Clusters in M31. II. Kinematics of the Globular Cluster System
Myung Gyoon Lee, Ho Seong Hwang, Sang Chul Kim +4
We present a kinematic analysis of the globular cluster(GC) system in M31. Using the photometric and spectroscopic database of 504 GCs, we have investigated the kinematics of the M…
The Globular Cluster System of M60 (NGC 4649). II. Kinematics of the Globular Cluster System
Ho Seong Hwang, Myung Gyoon Lee, Hong Soo Park +7
We present a kinematic analysis of the globular cluster (GC) system in the giant elliptical galaxy (gE) M60 in the Virgo cluster. Using the photometric and spectroscopic database o…
The Globular Cluster System of M60 (NGC 4649). I. CFHT MOS Spectroscopy and Database
Myung Gyoon Lee, Ho Seong Hwang, Hong Soo Park +7
We present the measurement of radial velocities for globular clusters in M60, giant elliptical galaxy in the Virgo cluster. Target globular cluster candidates were selected using t…
Wide-Field Survey of Globular Clusters in M31. I. A Catalog of New Clusters
Sang Chul Kim, Myung Gyoon Lee, Doug Geisler +6
We present the result of a wide-field survey of globular clusters (GCs) in M31 covering a 3deg x 3deg field c. We have searched for GCs on CCD images taken with Washington CMT1 fil…
Detection of CFIRB with AKARI/FIS Deep Observations
Woong-Seob Jeong, Chris P. Pearson, Hyung Mok Lee +8
The Cosmic Far-Infrared Background (CFIRB) contains information about the number and distribution of contributing sources and thus gives us an important key to understand the evolu…
The Connection between Star-Forming Galaxies, AGN Host Galaxies and Early-Type Galaxies in the SDSS
Joon Hyeop Lee, Myung Gyoon Lee, Taehyun Kim +3
We present a study of the connection between star-forming galaxies, AGN host galaxies, and normal early-type galaxies in the Sloan Digital Sky Survey (SDSS). Using the SDSS DR5 and…
Searching for rotating galaxy clusters in SDSS and 2dFGRS
Ho Seong Hwang, Myung Gyoon Lee
We present a result of searching for galaxy clusters that show an indication of global rotation using a spectroscopic sample of galaxies in SDSS and 2dFGRS. We have determined the…
Ultraluminous and Hyperluminous Infrared Galaxies in the SDSS, 2dFGRS and 6dFGS
Ho Seong Hwang, Stephen Serjeant, Myung Gyoon Lee +2
We present a result of cross-correlating the Infrared Astronomical Satellite Faint Source Catalogue (IRAS FSC) with the spectroscopic catalogues of galaxies in the Fourth Data Rele…
The Nature of Blue Early-Type Galaxies in the Goods Fields
Joon Hyeop Lee, Myung Gyoon Lee, Ho Seong Hwang
We present a study of the nature of the blue early-type galaxies (BEGs) in the GOODS north and south fields using the GOODS HST/ACS archival data. Using visual inspection, we have…
