- Simulation Astronomy, Physical Processes in Interstellar Matter, and Star Formation
Brief Introduction of Research
- I am studying physical processes in interstellar matter, especially star formation process using magnetohydrodynamics (MHD) and/or hydrodynamics (HD) simulations. Topics I am interested in are: non-linear structure-formation process seen in such as the evolution of interstellar matter and gravitational contraction from molecular clouds to stars. I am also interested in the development of high-resolution MHD/HD simulation schemes. Recently, I am extending my research to the observational visualization, in which the observational expectations of computer-made result of MHD/HD simulations are calculated and mock observations are made for the optical and radio telescopes of NAOJ, such as Subaru and ALMA.
