Groups of Dwarf Galaxies in the Local Universe
Sanjaya Paudel, Cristiano G. Sabiu, Suk-Jin Yoon +3
We present a systematic search for dwarf-galaxy groups in the local Universe (), identifying 28 systems containing at least four spectroscopically confirmed members selecte…
K-DRIFT Science Theme: Galaxies in the Faint Universe
Woowon Byun, Yongmin Yoon, Jongwan Ko +17
Low-surface-brightness (LSB) structures serve as evidence of the intricate mass assembly of galaxies, and dedicatedly studying them promises to give us profound insights into the e…
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…
Different Origins of Nucleated and Non-nucleated Dwarf Elliptical Galaxies: Identified by the Deep-learning
Sanjaya Paudel, Cristiano G. Sabiu, Suk-Jin Yoon +4
Dwarf elliptical galaxies (dEs) are the dominant population in galaxy clusters and serve as ideal probes for studying the environmental impact on galactic evolution. A substantial…
An isolated early-type dwarf galaxy that ran away from the group environment
Sanjaya Paudel, Cristiano G. Sabiu, Suk-Jin Yoon +2
Understanding the quenching mechanisms in dwarf galaxies is crucial for constraining models of galaxy formation and evolution. In this vein, isolated dwarf galaxies offer valuable…
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…
