Journal ArticleDOI
Annual Parallax Measurements of an Infrared Dark Cloud, MSXDC G034.43+00.24 with VERA
Tomoharu Kurayama,Akiharu Nakagawa,Satoko Sawada-Satoh,Katsuhisa Sato,Mareki Honma,Kazuyoshi Sunada,Tomoya Hirota,Hiroshi Imai +7 more
TL;DR: In this paper, the authors measured the annual parallax of the H2O maser source associated with an infrared dark cloud MSXDC G034.43+00.24 from the observations with VERA (VLBI Exploration of Radio Astrometry).
Journal ArticleDOI
The Dense Plasma Torus around the Nucleus of an Active Galaxy NGC1052
TL;DR: In this paper, a subparsec-scale dense plasma torus around an active galactic nucleus is revealed, and the coexistence of torus-like and spherical distributions of the plasma suggests a transition from radial accretion to rotational accretion around the nucleus.
