K-DRIFT: Unveiling New Imagery of the Hidden Universe
Jongwan Ko, Woowon Byun, Kwang-Il Seon +31
Low-surface-brightness (LSB) structures play a crucial role in understanding galaxy evolution by providing significant insights into galaxy interactions, the histories of mass asse…
Discovery of a large-scale H I plume in the NGC 7194 Group
Mina Pak, Junhyun Baek, Joon Hyeop Lee +5
We present the discovery of a new H I structure in the NGC 7194 group from the observations using the Karl G. Jansky Very Large Array. NGC 7194 group is a nearby (z ~ 0.027) small…
Performance Assessment of the KASI-Deep Rolling Imaging Fast-optics Telescope pathfinder
Woowon Byun, Jongwan Ko, Yunjong Kim +14
In a CDM universe, most galaxies evolve by mergers and accretions, leaving faint and/or diffuse structures, such as tidal streams and stellar halos. Although these structures ar…
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…
HI properties and star formation history of a fly-by pair of blue compact dwarf galaxies
Jinhyub Kim, Aeree Chung, O. Ivy Wong +3
A fly-by interaction has been suggested to be one of the major explanations for enhanced star formation in blue compact dwarf (BCD) galaxies, yet no direct evidence for this scenar…
Large-scale filamentary structures around the Virgo cluster revisited
Suk Kim, Soo-Chang Rey, Martin Bureau +9
We revisit the filamentary structures of galaxies around the Virgo cluster, exploiting a larger dataset based on the HyperLeda database than previous studies. In particular, this i…
Local Volume TiNy Titans: Gaseous Dwarf-Dwarf Interactions in the Local Universe
Sarah Pearson, Gurtina Besla, Mary E. Putman +8
In this paper, we introduce the Local Volume TiNy Titans sample (LV-TNT), which is a part of a larger body of work on interacting dwarf galaxies: TNT (Stierwalt et al. 2015). This…
The Extended Virgo Cluster Catalog
Suk Kim, Soo-Chang Rey, Helmut Jerjen +7
We present a new catalog of galaxies in the wider region of the Virgo cluster, based on the Sloan Digital Sky Survey (SDSS) Data Release 7. The Extended Virgo Cluster Catalog (EVCC…
The properties of early-type galaxies in the Ursa Major cluster
Mina Pak, Soo-Chang Rey, Thorsten Lisker +5
Using SDSS-DR7 and NASA/IPAC Extragalactic Database spectroscopic data, we identify 166 galaxies as members of the Ursa Major cluster with Mr < -13.5 mag. We morphological classify…
