Ram Pressure Stripping and ISM disc Truncation : Prediction vs. Observation
Seona Lee, Yun-Kyeong Sheen, Hyein Yoon +2
Ram pressure stripping (RPS) is known to be a key environmental effect that can remove interstellar gas from galaxies in a cluster. The RPS process is commonly described as a compe…
KMTNet Nearby Galaxy Survey: Overview and a Survey Description
Woowon Byun, Yun-Kyeong Sheen, Kwang-Il Seon +8
Recently, there has been an increasing demand for deep imaging surveys to investigate the history of the mass assembly of galaxies in detail by examining the remnants of mergers an…
Simulating Jellyfish Galaxies: A Case Study for a Gas-Rich Dwarf Galaxy
Jaehyun Lee, Taysun Kimm, Jérémy Blaizot +5
We investigate the formation of jellyfish galaxies using radiation-hydrodynamic simulations of gas-rich dwarf galaxies with a multi-phase interstellar medium (ISM). We find that th…
Multi-phase gas properties of extremely strong intervening DLAs towards quasars
A. Ranjan, R. Srianand, P. Petitjean +6
We present the results of a spectroscopic analysis of extremely strong damped Lyman-α absorbers (ESDLAs, log N(Hi)>=21.7) observed with VLT-XShooter. ESDLAs probe gas from within t…
KMTNet Nearby Galaxy Survey III. Deficient H flux in the Extended Disks of Spiral Galaxies
Woowon Byun, Yun-Kyeong Sheen, Kwang-Il Seon +9
We perform a deep wide-field imaging survey of nearby galaxies using H and broadband filters to investigate the characteristics of star formation in galaxies. Motivated by the f…
Formation of S0s in extreme environments II: the star-formation histories of bulges, discs and lenses
Evelyn J. Johnston, Alfonso Aragón-Salamanca, Amelia Fraser-McKelvie +8
Different processes have been proposed to explain the formation of S0s, including mergers, disc instabilities and quenched spirals. These processes are expected to dominate in diff…
KMTNet Nearby Galaxy Survey II. Searching for Dwarf Galaxies in Deep and Wide-field Images of the NGC 1291 system
Woowon Byun, Yun-Kyeong Sheen, Hong Soo Park +11
We present newly discovered dwarf galaxy candidates in deep and wide-field images of NGC 1291 obtained with the Korea Microlensing Telescope Network. We identify 15 dwarf galaxy ca…
Formation of S0s in extreme environments I: clues from kinematics and stellar populations
Lodovico Coccato, Yara L. Jaffé, Arianna Cortesi +8
Despite numerous efforts, it is still unclear whether lenticular galaxies (S0s) evolve from spirals whose star formation was suppressed, or formed trough mergers or disk instabilit…
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…

KMTNet Nearby Galaxy Survey I. : Optimal strategy for low surface brightness imaging with KMTNet
Woowon Byun, Yun-Kyeong Sheen, Luis C. Ho +8
In hierarchical galaxy formation models, galaxies evolve through mergers and accretions. Tidally-disrupted debris from these processes can remain as diffuse, faint structures, whic…
