A Naked Dwarf: Molecular Gas in the Completely Stripped HI Tail of VCC 1249
Bumhyun Lee, Aeree Chung, Paolo Serra +12
We present the first observational hints of the severe removal of both molecular and HI gas from the dwarf galaxy VCC 1249. This extreme stripping event is thought to be driven by…
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…
KMTNet Synoptic Survey of Southern Sky III: The First Data Release
Seo-Won Chang, Myungshin Im, Mankeun Jeong +13
We present the first public data release (DR1) of the KMTNet Synoptic Survey of Southern Sky (KS4). This deep, wide-field imaging survey covers a southern footprint of -85$^{\circ}…
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…
AllBRICQS: The Discovery of Luminous Quasars in the Northern Hemisphere
Yunyi Choi, Yuming Fu, Myungshin Im +16
We present the second catalog of bright quasars from the All-sky BRIght, Complete Quasar Survey (AllBRICQS), focusing on spectroscopically observed quasars in the Northern Hemisphe…
New Field OB and OBe Binaries of the SMC Wing: Observational Properties and Population Modeling
Irene Vargas-Salazar, M. S. Oey, Jan J. Eldridge +9
We present a radial velocity (RV) survey of the field OB and OBe stars of the SMC Wing. We use multi-epoch observations of 55 targets obtained with the Magellan IMACS and M2FS mult…
