Self-introduction

I am working on a visual analysis framework for three-dimensional integral field spectroscopy data in the fields of astrophysics and astronomy. I have created some programs since I was a junior high school student.

My hobby is taking astrophotographs. I go out to take photos under the starry sky near Kanto Plain when I have time. The photographs are sometimes applied and posted in astronomy magazines such as “Monthly Hoshi Navi” and “Monthly Astronomy Guide” in Japan.

Example astrophotographs
