I am especially interested in Cosmic Rays, some of which can reach 1020 eV.
They will tell us fundamental physics we don’t know yet.

Presentation on ground calibration processes of Xtend/XRISM at the IACHEC 2023
I gave a presentation on the on-ground calibration processes of Xtend for XRISM at IACHEC 2023 held in Germany on 23-27 April 2023. Exchanging ideas of experiments, analysis techniques, and future missions, is important and fun. These people are behind-the-scenes supporters of the X-ray astrophysics.
