Only obscured yet luminous active galactic nuclei are closely associated with galaxy mergers: Direct observational evidence from type 2 active galactic nuclei
Yongmin Yoon, Yongjung Kim, Dohyeong Kim +2
To establish a more comprehensive understanding of the connection between galaxy mergers and active galactic nuclei (AGNs), it is essential to disentangle the contributions of intr…
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…
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: 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 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…
Direct observational evidence that higher-luminosity type 1 active galactic nuclei are most commonly triggered by galaxy mergers
Yongmin Yoon, Yongjung Kim, Dohyeong Kim +2
We examine the connection between galaxy mergers and the triggering of active galactic nuclei (AGNs) using a sample of 614 type 1 AGNs at , along with a control sample of i…
