Outline of Final Research Achievements

We apply weak lensing analysis on the imaging data obtained with Subaru / Hyper Suprime-Cam (HSC), to reveal the matter distribution in the universe.
By evaluating the derived matter distribution, we examined the validity of the image analysis technique and made improvements. We also check the validity of the map with the independently obtained 3D galaxy distribution. As a result, we presented the downsizing evolution picture of star-forming galaxy established from other independent studies.
