Journal ArticleDOI
Toward a new geometric distance to the active galaxy ngc 4258. iii. final results and the hubble constant
Elizabeth Humphreys,Elizabeth Humphreys,Mark J. Reid,James M. Moran,Lincoln J. Greenhill,A. L. Argon +5 more
TL;DR: In this paper, a new geometric maser distance estimate to the active galaxy NGC 4258 is reported, which includes both disk warping and confocal elliptical maser orbits with differential precession.
Journal ArticleDOI
Proper motions and distances of H2O maser sources. I. The outflow in Orion-KL.
Journal ArticleDOI
Precise black hole masses from megamaser disks: black hole-bulge relations at low mass
Jenny E. Greene,Chien Y. Peng,Minjin Kim,Cheng-Yu Kuo,James A. Braatz,C. M.Violette Impellizzeri,James J. Condon,K. Y. Lo,Christian Henkel,Mark J. Reid +9 more
TL;DR: In this paper, the authors used the dynamics of H2O megamasers in circumnuclear disks to derive the Keplerian rotation of molecular disks starting at radii of a few tenths of a pc from the central BH.
Journal ArticleDOI
The megamaser cosmology project. III. Accurate masses of seven supermassive black holes in active galaxies with circumnuclear megamaser disks

TL;DR: In this paper, the authors used the very long baseline interferometry images and kinematics of water maser emission in six active galaxies: NGC 1194, NGC 2273 and NGC 2960, plus a seventh previously published, to determine accurate enclosed masses within the central ~0.3 pc of these galaxies, smaller than the radius of the sphere of influence of the central mass in all cases.
Journal ArticleDOI
Evidence for Warped Disks of Young Stars in the Galactic Center

TL;DR: It is shown that half of the W-R/O stars are compatible with being members of a clockwise rotating system, which is compatible with a coherent structure such as stellar filaments, streams, small clusters or possibly a disk in a dissolving state.
