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…
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 Black Hole - Bulge Mass Relation in Megamaser Host Galaxies
Ronald Läsker, Jenny E. Greene, Anil Seth +4
We present HST images for nine megamaser disk galaxies with the primary goal of studying photometric BH-galaxy scaling relations. The megamaser disks provide the highest-precision…
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…
The Megamaser Cosmology Project. VII. Investigating disk physics using spectral monitoring observations
Dominic W. Pesce, James A. Braatz, James J. Condon +5
We use single-dish radio spectra of known 22 GHz HO megamasers, primarily gathered from the large dataset observed by the Megamaser Cosmology Project, to identify Keplerian acc…
