A geometric distance to the galaxy NGC4258 from orbital motions in a nuclear gas disk
J. R. Herrnstein,J. R. Herrnstein,James M. Moran,Lincoln J. Greenhill,Philip J. Diamond,Makoto Inoue,Naomasa Nakai,Makoto Miyoshi,Carsten Henkel,Adam G. Riess +9 more
TL;DR: In this article, a geometric distance to the galaxy NGC4258 was derived from the direct measurement of orbital motions in a disk of gas surrounding the nucleus of this galaxy, which is the most precise absolute extragalactic distance yet measured.
Journal ArticleDOI
A 4% Geometric Distance to the Galaxy NGC4258 from Orbital Motions in a Nuclear Gas Disk
J. R. Herrnstein,James M. Moran,L. J. Greenhill,Philip J. Diamond,Makoto Inoue,Naomasa Nakai,Makoto Miyoshi,Carsten Henkel,Adam G. Riess +8 more
TL;DR: The water maser in the mildly active nucleus in the nearby galaxy NGC4258 traces a thin, nearly edge-on, subparsec-scale Keplerian disk.
Journal ArticleDOI
Water Maser Motions in W3(OH) and a Determination of Its Distance
K. Hachisuka,K. Hachisuka,Andreas Brunthaler,Andreas Brunthaler,Karl M. Menten,Mark J. Reid,Hiroshi Imai,Yoshiaki Hagiwara,Makoto Miyoshi,Shinji Horiuchi,Tetsuo Sasao +10 more
TL;DR: In this article, phase-referencing VLBA observations of H2O masers near the star-forming region W3(OH) to measure their parallax and absolute proper motions are reported.
Journal ArticleDOI
Discovery of a Subparsec Jet 4000 Radii Away from the Central Schwarzschild Engine of NGC 4258
J. R. Herrnstein,James M. Moran,Lincoln J. Greenhill,Philip J. Diamond,Makoto Miyoshi,Naomasa Nakai,Makoto Inoue +6 more
TL;DR: In this paper, the VLBI detection of compact continuum emission associated with the maser disk in NGC 4258 is reported, and the strongest emission is located about 0.5 mas (0.015 pc) north of the dynamical center of the disk.
Journal ArticleDOI
The origin of large peculiar motions of star-forming regions and spiral structures of our Galaxy
Junichi Baba,Yoshiharu Asaki,Junichiro Makino,Makoto Miyoshi,Takayuki R. Saitoh,Keiichi Wada +5 more
TL;DR: In this article, a high-resolution, self-consistent N-body+hydrodynamical simulation was used to explore how the spiral arms are formed and maintained, and how star-forming regions move.
