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…

JWST Spectroscopic View of a Rapidly Growing Dust-obscured Quasar at : Effect of Dust Extinction Correction on Black Hole Mass and Eddington Ratio Estimation

Dohyeong Kim, Myungshin Im

In the merger-driven galaxy evolution scenario, the central supermassive black holes (SMBHs) in dust obscured galaxies grow rapidly. Interestingly, a recent work \citep{suh24} on a…
