Outline of Final Research Achievements

We pursued researches to obtain the best performance from the cutting edge X-ray spectrometer, SXS, and to prepare for its observations. Although the SXS observation was stopped in about a month by malfunction of the ASTRO-H spacecraft, the SXS instrument performed perfectly in orbit. We obtained a scientific result which suggests systematic errors introduced by the macroscopic motion of hot gas is not large in mass determination of cluster of galaxies, which is important for the study of dark energy using clusters We also performed X-ray searches of dark matter. We obtained most stringent constraint on the mixing angle of steel neutrinos in 1 to 20 keV mass range using the Galactic halo observations of Suzaku X-ray astronomy satellite.
