Variability and the size-luminosity relation of the intermediate mass AGN in NGC 4395
Hojin Cho, Jong-Hak Woo, Edmund Hodges-Kluck +31
We present the variability study of the lowest-luminosity Seyfert 1 galaxy NGC 4395 based on the photometric monitoring campaigns in 2017 and 2018. Using 22 ground-based and space…
Impact of Galaxy Mergers on the Colours of Cluster Galaxies
Sree Oh, Keunho Kim, Joon Hyeop Lee +9
We examine the ultraviolet and optical colours of 906 cluster galaxies from the KASI-Yonsei Deep Imaging Survey of Clusters (KYDISC). Galaxies have been divided into two categories…
Formation of Blue-cored Dwarf Early-type Galaxies in a Cluster Environment: a Kinematical Perspective
Jiwon Chung, Soo-Chang Rey, Eon-Chang Sung +3
The presence of blue cores in some dwarf early-type galaxies (dEs) in galaxy clusters suggests the scenario of late-type galaxy infall and subsequent transformation into red, quies…
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…
KYDISC: Galaxy Morphology, Quenching, and Mergers in the Cluster Environment
Sree Oh, Keunho Kim, Joon Hyeop Lee +8
We present the KASI-Yonsei Deep Imaging Survey of Clusters (KYDISC) targeting 14 clusters at 0.015 < z < 0.144 using the Inamori Magellan Areal Camera and Spectrograph on the 6.5-m…
RR Lyrae Variable Stars in the Crater II Dwarf Galaxy
Seok-Joo Joo, Jaemann Kyeong, Soung-Chul Yang +10
We report the detection of RR Lyrae variable stars in Crater II, a recently discovered large and diffuse satellite dwarf galaxy of the Milky Way (MW). Based on B, V time-series pho…
