Constraining Quasar Feedback from Analysis of the Hydrostatic Equilibrium of the Molecular Gas in Their Host Galaxies

Qinyue Fei, Ran Wang, Juan Molina +4

We investigate the kinematics and dynamics of the molecular and ionized gas in the host galaxies of three Palomar-Green quasars at low redshifts, benefiting from the archival milli…

Massive Galaxy Mergers Have Distinctive Global HI Profiles

Pei Zuo, Luis C. Ho, Jing Wang +2

The global 21 cm HI emission-line profile of a galaxy encodes valuable information on the spatial distribution and kinematics of the neutral atomic gas. Galaxy interactions signifi…

The mass of Beta Pictoris c from Beta Pictoris b orbital motion

S. Lacour, J. J. Wang, L. Rodet +96

We aim to demonstrate that the presence and mass of an exoplanet can now be effectively derived from the astrometry of another exoplanet. We combined previous astrometry of Pic…

A geometric distance to the supermassive black Hole of NGC 3783

GRAVITY Collaboration, A. Amorim, M. Bauböck +45

The angular size of the broad line region (BLR) of the nearby active galactic nucleus (AGN) NGC 3783 has been spatially resolved by recent observations with VLTI/GRAVITY. A reverbe…
