| Outline of Final Research Achievements |
The purpose of this research is to constrain cosmological parameters such as the amount of dark matter in the universe from the massive datasets of the wide-field Subaru Hyper Suprime-Cam survey that is ongoing since 2014. The main results we have obtained are as follows. (1) We obtained the three-dimensional map of dark matter distribution in the universe from precise measurements of gravitational lensing effects from the Subaru HSC data. By comparing the gravitational lensing effects of Subaru HSC data with the theoretical predictions for the standard cosmological model, we measured the cosmological parameters such as the amount of dark matter. The cosmological model preferred by the Subaru HSC data shows some discrepancy with the model from the cosmic microwave background, and we anticipate a further development in coming years.
