Shigehiro Nagataki

The very existence of the universe itself is a mystery, and when we contemplate it, we cannot help but feel a sense of mystery. When we are confronted with the many mysterious phenomena and mysterious celestial bodies in the universe, we cannot help but feel that we have come into contact with something far beyond human knowledge. However, we do not regard them as mysteries or beyond human knowledge but try to understand them by the wisdom of humankind, which we call astrophysics. We use physics, super-computers, and observational instruments to understand these mysterious phenomena in astrophysics. Of course, the universe is rich even in undiscovered and unknown phenomena. We are interested in even these undiscovered phenomena, studying their possible existence and observability.

I am an astrophysicist. I received my degrees from the University of Tokyo and have studied the universe at the University of Tokyo, Kyoto University, and RIKEN. I have become an external professor at OIST since Dec. 2022. I would be happy to share the mysteries of the universe and the truth behind the mysteries with everyone at OIST.
