| Research Abstract |
Based on a three dimensional galacto chemodynamics simulation, we explore the formation and evolution of galaxies. We have suggested that Lyman alpha emitters can be identified with primordial galaxies catched in a supernova-dominated phase. After the early epoch, the simulated galaxy is dominated by stellar continuum radiation and transforms the Lyman break galaxies. Furthermore, we explore the evolution of the submillimetre brightness using the three dimensional radiative transfer in this model galaxy. We finally discuss physical relationship among these galaxies.
