New classification method for the dynamical state of galaxy clusters with a Gaussian mixture model
Hyowon Kim, Marco Canducci, Rory Smith +5
Galaxy clusters are the largest gravitationally bound systems, and they continue their growth through mergers in a hierarchical ΛCDM Universe. Therefore, we can describe the merger…
K-DRIFT Science Theme: New Theoretical Framework Using the Galaxy Replacement Technique for LSB studies
Kyungwon Chun, Jihye Shin, Rory Smith +13
Low-surface-brightness (LSB) structures provide critical insights into the hierarchical formation of galaxies and galaxy clusters. The KASI Deep Rolling Imaging Fast Telescope (K-D…
Convolutional Neural Networks for classifying galaxy mergers: Can faint tidal features aid in classifying mergers?
Yeonkyung Lee, Hyunmi Song, Jihye Shin +3
Identifying mergers from observational data has been a crucial aspect of studying galaxy evolution and formation. Tidal features, typically fainter than 26 …
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…
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…
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…
Emergence of the Galaxy Morphology-Star Formation Activity-Clustercentric Radius Relations in Galaxy Clusters
Sungwook E. Hong, Changbom Park, Preetish K. Mishra +7
We investigate when and how the relations of galaxy morphology and star forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy cluste…
Understanding Stellar Mass-Metallicity and Size Relations in Simulated Ultra-Faint Dwarf Galaxies
Minsung Go, Myoungwon Jeon, Yumi Choi +7
Reproducing the physical characteristics of ultra-faint dwarf galaxies (UFDs) in cosmological simulations is challenging, particularly with respect to stellar metallicity and galax…
Tracing the Formation History of Intrahalo Light with Horizon Run 5
Hyungjin Joo, M. James Jee, Juhan Kim +8
We investigate the formation history of intrahalo light (IHL) using the high-resolution (~1 kpc), large-scale (~Gpc) cosmological hydrodynamical simulation, Horizon Run 5 (HR5). IH…
Testing Lyman Alpha Emitters and Lyman-Break Galaxies as Tracers of Large-Scale Structures at High Redshifts
Sang Hyeok Im, Ho Seong Hwang, Jaehong Park +21
We test whether Lyman alpha emitters (LAEs) and Lyman-break galaxies (LBGs) can be good tracers of high-z large-scale structures, using the Horizon Run 5 cosmological hydrodynamica…
Formation channels of the diffuse lights in the groups and clusters over time
Kyungwon Chun, Jihye Shin, Jongwan Ko +2
We explore the formation of the intragroup light (IGL) and intracluster light (ICL), representing diffuse lights within groups and clusters, since . For this, we perform mul…
New observational recipes for measuring dynamical state of galaxy clusters
Hyowon Kim, Rory Smith, Jongwan Ko +4
During cluster assembly, a cluster's virialization process leaves behind signatures that can provide information on its dynamical state. However, no clear consensus yet exists on t…
Spatial Distribution of Intracluster Light versus Dark Matter in Horizon Run 5
Jaewon Yoo, Changbom Park, Cristiano G. Sabiu +11
One intriguing approach for studying the dynamical evolution of galaxy clusters is to compare the spatial distributions among various components, such as dark matter, member galaxi…
Understanding the Formation and Evolution of Dark Galaxies in a Simulated Universe
Gain Lee, Ho Seong Hwang, Jaehyun Lee +2
We study the formation and evolution of dark galaxies using the IllustrisTNG cosmological hydrodynamical simulation. We first identify dark galaxies with stellar-to-total mass rati…
