Dynamics of Non-Steady Spiral Arms in Disk Galaxies
Junichi Baba, Takayuki R. Saitoh, Keiichi Wada
In order to understand the physical mechanisms underlying non-steady stellar spiral arms in disk galaxies, we analyzed the growing and damping phases of their spiral arms using thr…

Radiation-driven Fountain and Origin of Torus around Active Galactic Nuclei
Keiichi Wada
We propose a plausible mechanism to explain the formation of the so-called "obscuring tori" around active galactic nuclei (AGNs) based on three-dimensional hydrodynamic simulations…

Analysis of H2O Masers in Sharpless 269 using VERA Archival data --- Effect of maser structures on astrometric accuracy
Makoto Miyoshi, Yoshiharu Asaki, Keiichi Wada +1
Astrometry using H2O maser sources in star forming regions is expected to be a powerful tool to study the structures and dynamics of our Galaxy. Honma et al. (2007) (hereafter H200…
