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…

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…

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…
