K-DRIFT Science Theme: Galactic Cirrus Clouds and Circumgalactic Medium
Kwang-il Seon, Jaehyun Lee, Jongwan Ko +8
In this paper, we review the extended halo material and the circumgalactic medium (CGM), including both dust and gas, and discuss promising science cases that could be realized usi…
A New Collision Avoidance Fiber Assignment Algorithm for Robotic Fiber Positioners in Multi-Object Spectroscopy
Minseong Kwon, Ho Seong Hwang, Jong Chul Lee +22
We present a new fiber assignment algorithm for a robotic fiber positioner system in multi-object spectroscopy. Modern fiber positioner systems typically have overlapping patrol re…
K-DRIFT Science Theme: Illuminating the Next Era of Galaxy Cluster Science
Jaewon Yoo, Kyungwon Chun, Jongwan Ko +13
The KASI Deep Rolling Imaging Fast Telescope (K-DRIFT) is a pioneering instrument designed to explore low-surface-brightness (LSB) phenomena. This white paper presents a compelling…
On the Origin of Gas-stripping of Galaxies in Group Environments
Jinsu Rhee, Christophe Pichon, Yohan Dubois +12
We investigate how low-mass group environments () influence the gas content of their satellite galaxies with using…
The Role of Pre-Processing in Tidal Feature Formation within Galaxy Clusters
Kyungwon Chun, Jihye Shin, Jongwan Ko +3
We investigate the formation of tidal features, such as tidal tails, streams, and shell-like structures, composed of stars stripped from satellites within galaxy clusters. For this…
Tracing Dark Matter in the Central Regions of Galaxy Clusters Using Galaxies, Gas, and Intracluster Light in TNG300: Connections to Cluster Dynamical State
Jaewon Yoo, Jihye Shin, Ho Seong Hwang +4
Recent studies have highlighted the potential of intracluster light (ICL) as a dark matter tracer. Moreover, the ICL co-evolves with the brightest cluster galaxy (BCG) and the host…
