Outline of Final Research Achievements

The microcalorimeter SXS (Soft X-ray Spectrometer) onboard Hitomi demonstrated the energy resolution of 4.9 eV (FWHM at 5.9 keV) in orbit. In the initial phase, Hitomi observed the Perseus cluster with more than 300 ks, and made new limitations on the hot plasma in the cluster of galaxies. In this year, those scientific results are given in PASJ special issue, and the hardware papers are published in JATIS special issue. In particular, the in-orbit performance of the digital pulse processing system are summarized as Ishisaki et al. in the JATIS special issue.
The XARM (X-ray Astronomy Recovery Mission) to recover the science of Hitomi is under progress. The XARM has a microcalorimeter instrument named Resolve, and an X-ray CCD instrument named Xtend. Ishisaki has become an instrument PI of Resolve in Japan, and the Resolve team in Japan made investigations on design changes from Hitomi SXS in collaboration with the Resolve team at NASA.
