Images & spectra from the XRISM’s first light observations have been published! Excellent spectral performance of Resolve and large field-of-view imaging capability of Xtend have been verified. Now we are preparing for huge tasks for scientific publications. For details, visit the JAXA’s official webpage.

Resolve and Xtend onboard XRISM have been turned on and are now almost ready for observations. Recent post from the XRISM X (Twitter) account.

Our paper on the discovery of global shock deceleration and reflection in the supernova remnant RCW 103 has been accepted for publication in ApJ. (arxiv link)We found that X-ray rims and knots largely changed their speeds and directions of motion in this 20 years, although the age of the remnant is thought to be greaterContinue reading “Very recent shock reflection in the supernova remnant RCW 103 ?”

The X-ray astronomical satellite XRISM has been launched from the Tanegashima Space Center, Japan at 8:42 AM, Sep 7, 2023. The launch was successful without any problems, and the initial operation is going on. Hope to see wonderful data…! Image credit: MHI

I have moved from Konan University to ISAS (Institute of Space and Astronautical Science) of JAXA (Japan Aerospace Exploration Agency), which is located in Fuchinobe, Kanagawa. ISAS is the headquarter of space missions including the XRISM X-ray satellite.

I gave a talk at APRIM2023 about systematic trends and variety of particle acceleration processes in supernova remnants (almost the same as that for ICRC 2023). I am glad that I can give a presentation in my hometown!

I gave a presentation at the ICRC2023, which was held at Nagoya University. The talk was about systematic trends and variety of particle acceleration processes in supernova remnants. The proceeding is available here.

I was awarded the XRISM outstanding contribution award for young researchers for my contribution to the CCD team (Xtend). My primary contribution is the management/verification of operation procedures. After the launch, I will manage the detector calibration as well in collaboration with other X-ray satellites in the world.

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.

I have attended a XRISM spacecraft test after it was shipped to the Tanegashima island, where the launch site is located. We confirmed the performance of Xtend. This will be the final detailed test before the launch.
