Abstract

Elemental abundance ratios of stars and DLAs retain the information of (1) the formation and evolutionary histories of galaxies and (2) the properties of the first stars. For extremely metal-poor stars and DLAs, the elemental abundance patterns can be explained by the first enrichment from core-collapse supernovae. I am simulating chemodynamical evolution of galaxies using my hydrodynamical code that includes star formation and chemical enrichment from core-collapse and Type Ia supernovae and AGB stars. This successfully reproduces various observations such as the elemental abundance ratios in the Galactic bulge, disk, and thick disk, radial gradients, and mass-metallicity relations of galaxies. I will also show some new results with AGN feedback.
