| Outline of Final Research Achievements |
This research program carried out preparation studies for the wide-area Subaru Hyper Suprime-Cam galaxy survey that enables us to explore precision cosmology. The main achievements are: (1) We established the concrete foundation and platform needed for the international HSC collaboration that consists of researchers from Japan, Princeton University and Taiwan. (2) Under a strong leadership of this research program PI (M. Takada), we built up the survey design of HSC galaxy survey based on the discussion and preparation studies we had in the collaboration. The proposed HSC survey was approved by the Subaru community and the Subaru 300 nights are granted for the HSC survey. (3) We developed a novel cosmological method of combining imaging and spectroscopic galaxy surveys for the same region of the sky to constrain cosmological parameters.
