PIXEL2026@Miyazaki
We held the conference “PIXEL2026” at Miyazaki Kanko hotel. Around 150 people came to Miyazaki. The conference was about detectors used in high-energy particle physics and astrophysics. As an excursion, we went to the “Obi” old castle town and “Udo” shrine. One of the highlights will be organizers trying to act as tour (bus) guides!
TeVPA in Tendo, Japan
I gave a presentation on an ongoing study of diffuse X-rays around microquasars at the conference “TeVPA” held in Tendo, Japan. We had a lot of discussion on how we keep updating our multi-wavelength work on microquasars. The welcome reception held at the Hiroshige museum was great as well. We were allowed to walk around…

It was a great experience. I was asked to give a talk about our XRISM observation of the supernova remnant Sgr…
