Red Type-1 Quasars after Cosmic Noon and Impact on -related Quasar Statistics
Yongjung Kim, Dohyeong Kim, Myungshin Im +1
Over the past decades, nearly a million quasars have been explored to shed light on the evolution of supermassive black holes and galaxies. The ultraviolet-to-optical spectra of ty…
Multi-Object Spectroscopy of Galaxy Clusters at in Ultra Deep Survey Field with Different Star-formation Properties and Large-scale Environments
Seong-Kook Lee, Myungshin Im, Bomi Park +3
While galaxy clusters are dominated by quiescent galaxies at local, they show a wide range in quiescent galaxy fraction (QF) at higher redshifts. Here, we present the discovery of…
The Robotic MAAO 0.7m Telescope System: Performance and Standard Photometric System
Gu Lim, Dohyeong Kim, Seonghun Lim +8
We introduce a 0.7m telescope system at the Miryang Arirang Astronomical Observatory (MAAO), a public observatory in Miryang, Korea. System integration and a scheduling program ena…
Estimators of Bolometric Luminosity and Black Hole Mass with Mid-infrared Continuum Luminosities for Dust-obscured Quasars: Prevalence of Dust-obscured SDSS Quasars
Dohyeong Kim, Myungshin Im, Minjin Kim +4
We present bolometric luminosity () and black hole (BH) mass () estimators based on mid-infrared (MIR) continuum luminosity (hereafter, ) that…
The Early Light Curve of a Type Ia Supernova 2021hpr in NGC 3147: Progenitor Constraints with the Companion Interaction Model
Gu Lim, Myungshin Im, Gregory S. H. Paek +19
The progenitor system of Type Ia supernovae (SNe Ia) is expected to be a close binary system of a carbon/oxygen white dwarf (WD) and a non-degenerate star or another WD. Here, we p…
A Mid-infrared Flare in the Seyfert Galaxy NGC 3786: A Changing-look Event Triggered by an Obscured Tidal Disruption Event?
Suyeon Son, Minjin Kim, Luis C. Ho +2
We report an exceptional mid-infrared flare in the Seyfert 1.8 NGC 3786. In the multi-epoch data from the Wide-field Infrared Survey Explorer, the nuclear mid-infrared brightness o…
