Outline of Final Research Achievements

We have developed a medium-band filter, IB945, to be equipped to the new prime-focus camera of the Subaru Telescope, Hyper Suprime-Cam (HSC). This filter is to be used to efficiently sample star-forming galaxies at redshift z=6.6 which is the completion epoch of the Cosmic Reionization. We have also performed a large and high-resolution N-body simulation of the structure formation in the Universe in order to realize a large numerical simulation of the Cosmic Reionization by using the K-computer. For a radiative transfer simulation based on the N-body result, we have also modeled the ionizing photon emissivity depending on the dark-matter halo mass obtained in the N-body simulation. In addition, we have studied the galaxy formation and evolution and the intergalactic medium in the distant Universe.
