Outline of Final Research Achievements

We published several papers for X-ray studies of SNRs with spectrometers during the research period. We also developed the soft X-ray imager (SXI) onboard ASTRO-H (Hitomi), which was successfully launched on February 2016. Although Hitomi was lost by an accident of the attitude control system, we had observed several celestial sources before its lost and confirmed the in-orbit performance of the instruments.
