Dominic W. Pesce,Dominic W. Pesce,J. A. Braatz,Mark J. Reid,Adam G. Riess,Adam G. Riess,Daniel Scolnic,James J. Condon,F. Gao,F. Gao,Christian Henkel,Christian Henkel,C. M. V. Impellizzeri,C. Y. Kuo,C. Y. Kuo,K. Y. Lo +15 more
TL;DR: In this article, an improved approach for fitting maser data and obtained better distance estimates for four galaxies previously published by the Megamaser Cosmology Project: UGC 3789, NGC 6264 and NGC 6323, with a confidence level varying from 95% to 99% for different treatments of the peculiar velocities.

TL;DR: In this article, the scaling relations between macroscopic galaxy properties and supermassive black hole (BH) mass were investigated using new precision measurements of black hole masses from water megamaser disks.

The Megamaser Cosmology Project. VIII. A Geometric Distance to NGC 5765b
F. Gao,F. Gao,James A. Braatz,Mark J. Reid,K. Y. Lo,James J. Condon,Christian Henkel,Christian Henkel,Cheng-Yu Kuo,C. M. V. Impellizzeri,Dominic W. Pesce,W. Zhao +11 more
TL;DR: In this paper, a new geometric distance measurement to the megamaser galaxy NGC 5765b is presented, based on a series of very long baseline interferometry observations, which confirm the water masers trace a thin, sub-parsec Keplerian disk around the nucleus, implying an enclosed mass of 4.55 ± 0.40×10(7) M(⊙).

TL;DR: In this paper, the authors presented VLBI maps of nuclear water masers toward five galaxies and fit Keplerian rotation curves to estimate their supermassive black hole (SMBH) masses.
