First Light for GRAVITY Wide: Large Separation Fringe Tracking for the Very Large Telescope Interferometer
GRAVITY+ Collaboration, :, R. Abuter +114
GRAVITY+ is the upgrade of GRAVITY and the Very Large Telescope Interferometer (VLTI) with wide-separation fringe tracking, new adaptive optics, and laser guide stars on all four 8…
The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits
GRAVITY Collaboration, R. Abuter, N. Aimar +62
The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…
Deep Images of the Galactic Center with GRAVITY
GRAVITY Collaboration, R. Abuter, N. Aimar +65
Stellar orbits at the Galactic Center provide a very clean probe of the gravitational potential of the supermassive black hole. They can be studied with unique precision, beyond th…
The Megamaser Cosmology Project. X. High Resolution Maps and Mass Constraint for SMBHs
W. Zhao, J. A. Braatz, J. J. Condon +8
We present high resolution (sub-mas) VLBI maps of nuclear H2O megamasers for seven galaxies. In UGC6093, the well-aligned systemic masers and high-velocity masers originate in an e…
On Estimating the Mass of Keplerian Accretion Disks in H2O Maser Galaxies
C. -Y. Kuo, M. J. Reid, J. A. Braatz +3
H2O maser disks with Keplerian rotation in active galactic nuclei offer a clean way to determine accurate black hole mass and the Hubble constant. An important assumption made in u…
The Megamaser Cosmology Project.IX. Black hole masses for three maser galaxies
F. Gao, J. A. Braatz, M. J. Reid +9
As part of the Megamaser Cosmology Project (MCP), we present VLBI maps of nuclear water masers toward five galaxies. The masers originate in sub-parsec circumnuclear disks. For thr…
Megamaser Disks Reveal a Broad Distribution of Black Hole Mass in Spiral Galaxies
Jenny E. Greene, Anil C. Seth, Minjin Kim +8
We use new precision measurements of black hole masses from water megamaser disks to investigate scaling relations between macroscopic galaxy properties and supermassive black hole…
The Megamaser Cosmology Project VIII. A Geometric Distance to NGC 5765b
F. Gao, J. A. Braatz, M. J. Reid +7
As part of the Megamaser Cosmology Project (MCP), here we present a new geometric distance measurement to the megamaser galaxy NGC 5765b. Through a series of VLBI observations, we…
