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…
Parsec-scale jet properties of the gamma-ray quasar 3C 286
T. An, B. -Q. Lao, W. Zhao +4
The quasar 3C~286 is one of two compact steep spectrum sources detected by the {\it Fermi}/LAT. Here, we investigate the radio properties of the parsec(pc)-scale jet and its (possi…
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…
