Project Title

Chemodynamical Simulation of Milky Way Galaxy

Brief Description for General Publications

Using my self-consistent 3D hydrodynamical code (Kobayashi 2004), I will simulate the formation and evolution of galaxies across Cosmic time, from the observed initial condition of the Universe. Including detailed physical processes such as star formation, supernovae, and chemical enrichment, I will predict the time/redshift evolution of the spatial distribution of elements. In 2011, I performed simulations of a Milky Way-type Galaxy with 7 million particles, which shows a better agreement with observations but there is some inconsistencies. In 2012, I will increase the resolution with 100 million particles. From the comparison with the observed chemical abundances in our Milky Way Galaxy, I will predict the formation and evolutionary histories of the Milky Way Galaxy. In 2012, a new multi-object spectrograph will be available on the Anglo-Australian Telescope, which will observe the detailed elemental abundance of million stars. Before that, I will provide a theoretical prediction that can be compared with such detailed observations.
