Research Themes
Development of high-resolution soft X-ray spectrometer onboard XRISM satellite
JAXA's XRISM is an Japan-US international X-ray astronomy satellite, and will be launched in 2023. The Resolve instrument is a high-resolution spectrometer utilizing an X-ray microcalorimeter array, under close US-Japan international collaboration. It has an energy resolution 20 time better than semiconductor detectors. I am now developing the Resolve with NASA, JAXA, and other university/institute groups. With the Resolve, we will observe merging of galaxy clusters and reveal their evolution.
