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.

Jun 14, 2017The solar corona is full of dynamic phenomena, e.g., solar flares, micro flares in active regions, jets in coronal holes and in the polar regions, X-ray bright points in quiet regions, etc. They are accompanied by interesting physical processes, namely, magnetic reconnection, particle acceleration, shocks, waves, flows, evaporation, heating, cooling, and so on. The understandings of these phenomena and processes have been progressing step-by-step with the evolution of the observation technology in EUV and X-rays from the space. But, there are fundamental questions remain unanswered, or haven't even addressed so far. Our scientific objective is to understand underlying physics of dynamic phenomena in the solar corona, covering some of the long-standing questions in solar physics such as particle acceleration in flares and coronal heating. In order to achieve these science objectives, we identify the imaging spectroscopy (the observations with spatial, temporal and energy resolutions) in the soft X-ray range (from ~0.5 keV to ~10 keV) is a powerful approach for the detection and analysis of energetic events.
