I have attended the conference Supernova Remnants III: An Odyssey in Space after Stellar death held at Crete, Greece, in this June. I gave a poster presentation about our recent paper on decelerating X-ray knots and rims of RCW 103. I remember attending the “Supernova Remnants II” held at the same place in 2019. IContinue reading “Supernova remnant conference at Crete”

I had a presentation and a lot of discussion at the 16th IACHEC meeting at Parador de La Granja (Spain). Cross-calibration of X-ray missions are of increasing importance with the emergence of new instruments including XRISM and fast-evolving Chinese missions.

The CCD camera Xtend on XRISM observed SN1006. Thanks to its large field of view of 38×38 arcmin, entire emission of SN1006 was covered with one pointing. The image is really amazing. (Image credit: JAXA)

I gave a presentation on XRISM/Xtend’s in-orbit performance at the XRISM workshop held in Geneva in Feb 12–14. Many young scientists were there, hoping to produce wonderful scientific results with XRISM.

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!
