Description
I will give a brief summary on the origin of elements using Galactic chemical evolution with Pop II and Pop I stars. Then I will discuss the Pop III nucleosynthesis using extremely metal-poor stars in the Milky Way. Namely, I will present our new analysis with machine learning to find “the first stars were not alone”. Finally, I will discuss the first chemical enrichment in the Universe, comparing our cosmological, chemodynamical simulations of galaxies to the observations such as with the James Webb Space Telescope.
