| Abstract |
To understand the galaxy evolution, it is essential to understand the evolution of dust in galaxies. Up to now, dust evolution has been studied with various dust evolution models, but most of them are based on the assumption of a typical size of grains. However, since grain size distribution of galaxies varies by various processes (dust destruction by SN shocks, metal accretion onto surface of grains and etc.) [Yamasawa et al. (2011), Hirashita et al. (2011)], grain size distribution is a very important ingredient to understand the dust evolution. In this talk, we would introduce the dust evolution model with grain size distribution and report our first results. |
