Compact elliptical galaxies in different local environments: a mixture of galaxies with different origins?
Suk Kim, Hyunjin Jeong, Soo-Chang Rey +4
We present the stellar populations of 138 compact elliptical galaxies (cEs) in the redshift range of using the Sloan Digital Sky Survey (SDSS) DR12. Our cEs are divided…
RR Lyrae Stars in the Field of Sagittarius II
Seok-Joo Joo, Jaemann Kyeong, Soung-Chul Yang +10
We present the detection of RR Lyrae variable stars in the field of the Sagittarius II (Sgr II) ultra-faint dwarf (UFD) galaxy. Using B, V time-series photometry obtained with the…
A Possible Relic Star Cluster in the Sextans Dwarf Galaxy
Hak-Sub Kim, Sang-Il Han, Seok-Joo Joo +2
We report a possible discovery of a relic star cluster in the Sextans dwarf spheroidal galaxy. Using the \textit{hk} index (()()) as a photometric metallicity…
Wobbling galaxy spin axes in dense environments
Jaehyun Lee, Suk Kim, Hyunjin Jeong +7
The orientation of galaxy spin vectors within the large scale structure has been considered an important test of our understanding of structure formation. We investigate the angula…
Assembling the Milky Way bulge from globular clusters: Evidence from the double red clump
Young-Wook Lee, Seungsoo Hong, Dongwook Lim +4
The two red clumps (RCs) observed in the color-magnitude diagram of the Milky Way bulge is widely accepted as evidence for an X-shaped structure originated from the bar instability…
Discovery of the kinematic alignment of early-type galaxies in the Virgo cluster
Suk Kim, Hyunjin Jeong, Jaehyun Lee +4
Using the kinematic position angles (PA_kin), an accurate indicator for the spin axis of a galaxy, obtained from the ATLAS3D integral-field-unit (IFU) spectroscopic data, we discov…
