Place:	Seminar Room A
Abstract:	Space science observations require the most advanced technology. Through the developments of a series of X-ray satellites, including the Hitomi satellite, we have established cutting edge technologies to make highly sensitive hard X-ray and gamma-ray detectors to study non-thermal phenomena in the universe. Recently, it has turned out that these technologies meet the long-standing demands from other fields such as (1) finding hot spots in the Fukushima, (2) imaging of muon X-rays from muonic atoms, and (3) in-vivo 3D imaging of small animals to study Cancer Stem Cells. New requirements from these applications further advance the performance of the detectors and enable us to design future hard X-ray and gamma-ray missions with much higher sensitivities than present ones. In this seminar, I will introduce recent progress of hard X-ray and gamma-ray imaging in space and on the ground. Also, I will discuss scientific topics which have triggered us to develop new hard X-ray and Gamma-ray astronomy missions for the future.
