| Outline of Final Research Achievements |
Our habitat, the Milky Way galaxy, is one of spiral galaxies in the Universe. In this project, in order to reveal the formation and evolution of the spiral galaxies via comparisons with latest observations, in particular, dynamical evolution and the ISM properties, we developed the N-body/hydrodynamic simulation code including the detailed ISM processes. As a result, we proposed the new diagnostics of spiral theories between the classical and our new models based on simulation results. Furthermore, we achieved the 100 million-scale simulation of the Milky Way-like barred spiral galaxy. This simulation result was visualized as a 3D movie and opened to the public from NAOJ/4D2U. This movie won the Grand Prix promoted by the Advanced Imaging Society.
