X線観測を中心に、飛翔体を用いた太陽物理学の研究を行なっています。 「ひので」、「ようこう」、SDOなどの衛星に搭載されたX線望遠鏡やEUV望遠鏡をはじめとする、飛翔体観測機器のデータを用いて、太陽フレアで発生するプラズマ粒子の爆発的な加熱と加速や、それらの惑星間空間への影響など、コロナ中のプラズマ活動現象の理解をめざします。 また、「ようこう」の硬X線望遠鏡HXTや「ひので」のX線望遠鏡XRTなど、新しい観測を可能とする装置開発を手がけており、現在は、将来の太陽高エネルギープラズマの研究に向けた、高空間分解能・低散乱性能を持つX線斜入射ミラーや、光子計測型の高速X線ピクセル検出器などの開発研究、および将来の飛翔体ミッションの検討を進めています。 I have been engaged in solar physics research with space and sub-orbital observations chiefly in X-ray wavelengths. By use of data from instruments such as X-ray or EUV telescopes aboard Hinode, Yohkoh, and SDO, I aim to understand plasma activities in the solar corona, including explosive heating and acceleration of coronal plasmas during flares and their interplanetary consequences. Meanwhile, I have participated in the development of instruments which make possible new observations of the solar corona; e.g., Hard X-ray Telescope (HXT) aboard Yohkoh and X-Ray Telescope (XRT) aboard Hinode. Currently, I am working on research and development of grazing-incidence X-ray mirrors (Wolter mirrors) of high spatial resolution/low scattering performance as well as photon-counting-type high-speed X-ray pixel detectors, together with studies on future space solar X-ray missions.

We have developed an advanced UV spectropolarimeter called Chromospheric LAyer SpectroPolarimeter (CLASP2), aimed at achieving very high accuracy measurements (<0.1% at 3 sigma) of the linear (Q/I and U/I) and circular (V/I) polarizations of the M...
