Professor, Faculty of Science (High-energy astrophysics)

GUNJI Shuichi

In the universe, phenomena exist that far exceed our imagination. For instance, gamma-ray bursts release the energy equivalent of what the sun emits over its lifetime in just a few seconds. Black holes possess gravitational fields so strong that not even light can escape. Magnetars have magnetic fields a quadrillion times stronger than Earth's. These celestial bodies emit high-energy electromagnetic waves (like X-rays and gamma rays), and even from a distance, we can capture these waves to study their properties. We are collaborating with domestic and international research groups to investigate these high-energy celestial bodies using cutting-edge equipment. Currently, we're analyzing data from the IXPE satellite, which can measure the polarization of X-rays, while concurrently participating in the development of a next-generation small satellite capable of quickly detecting gamma-ray bursts at the edge of the universe.
