Multiple Populations of the Large Magellanic Cloud Globular Cluster NGC 2257: No Major Environmental Effect on the Formation of Multiple Populations of the Old Globular Clusters in Large Magellanic Cloud
Jae-Woo Lee, Tae-Hyeong Kim, Hak-Sub Kim +3
How the environment of the host galaxy affects the formation of multiple populations (MPs) in globular clusters (GCs) is one of the outstanding questions in the near-field cosmolog…
Similar image retrieval using Autoencoder. I. Automatic morphology classification of galaxies
Eunsuk Seo, Suk Kim, Youngdae Lee +4
We present the construction of an image similarity retrieval engine for the morphological classification of galaxies using the Convolutional AutoEncoder (CAE). The CAE is trained o…
Nonlinear Color-Metallicity Relations of Globular Clusters. XI. Nonlinearity Effect Revealed by NGC 5128 (Centaurus A) and NGC 4594 (Sombrero) Galaxies
Hak-Sub Kim, Suk-Jin Yoon, Sang-Yoon Lee +1
Metallicity distributions (MDs) of globular clusters (GCs) provide crucial clues for the assembly and star formation history of their host galaxies. GC colors, when GCs are old, ha…
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…
Narrowband Ca Photometry for Dwarf Spheroidal Galaxies. I. Chemostructural Study on Draco, Sextans, and Canes Venatici I
Sang-Il Han, Hak-Sub Kim, Suk-Jin Yoon +4
A few dozen dwarf satellite galaxies of the Milky Way have been discovered, which are often viewed as the remaining building blocks of our Galaxy. The follow-up spectroscopy showed…
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…
