| Research Abstract |
We are involved in building a 1.2 Giga pixel CCD camera (Hyper Suprime Cam) to be mounted on the prime focus of the Subaru telescope. With this wide-field camera, we plan to conduct extensive wide-filed deep survey to investigate weak lensing. This data will be used to develop 3-D mass mapping of the universe. It, in turn, will be used to study Dark Energy. This year, the camera was mounted on the Subaru telescope at Hawaii and successfully commissioned. A large imaging survey with 300 nights at Subaru has been approved.
