Varstrometry for Off-nucleus and Dual sub-Kpc AGN (VODKA): How Well-centered Are Low-z AGN?
Yue Shen, Hsiang-Chih Hwang, Nadia Zakamska +1
Off-nucleus active galactic nuclei (AGN) can be signposts of inspiraling supermassive black holes (SMBHs) on galactic scales, or accreting SMBHs recoiling after the coalescence of…
Lifetime of short-period binaries measured from their Galactic kinematics
Hsiang-Chih Hwang, Nadia Zakamska
As a significant fraction of stars are in multiple systems, binaries play a crucial role in stellar evolution. Among short-period (<1 day) binary characteristics, age remains one o…
Varstrometry for Off-nucleus and Dual sub-Kpc AGN (VODKA): Methodology and Initial Results with Gaia DR2
Hsiang-Chih Hwang, Yue Shen, Nadia Zakamska +1
Gaia's milli-arcsec (mas) astrometric precision allows systematic identification of optically-selected sub-kpc dual active galactic nuclei (AGN), off-nucleus AGN, and small-scale l…
A Pseudodisk Threaded with a Toroidal and Pinched Poloidal Magnetic Field Morphology in the HH 211 Protostellar System
Chin-Fei Lee, Woojin Kwon, Kai-Syun Jhan +6
The HH 211 protostellar system is currently the youngest Class 0 system found with a rotating disk. We have mapped it at ~ 50 au (0.16") resolution, studying its magnetic field mor…
Characterizing the local relation between star formation rate and gas-phase metallicity in MaNGA spiral galaxies
Laura Sánchez-Menguiano, Jorge Sánchez Almeida, Casiana Muñoz-Tuñón +4
The role of gas accretion in galaxy evolution is still a matter of debate. The presence of inflows of metal-poor gas that trigger star formation bursts of low metallicity has been…
