|Outline of Final Research Achievements
How the first stars in the Universe formed? Where and to what extent their survivors are remaining in the Milky Way? This research group has established the photometric search for such ancient stars and also explored the detailed theoretical investigations on the formation of the first stars and the related galaxy formation histories. In order to search for extremely metal-poor stars as the remnants of the first stars using the Hyper-Suprime Camera (HSC) attached on Subaru telescope, we have made a set of specially designed narrow-band filters. Also, high-resolution cosmological simulations have been carried out on the formation of the first stars, which have enabled us to establish the theoretical framework for the survival rate of such ancient stars in the present time.
