Research Areas
Computational Astrophysics Laboratory promotes EUSO (Extreme Universe Space Observatory) mission that observes giant-air showers by ultra-high-Energy cosmic-ray from the orbit. EUSO is a super wide-field (ア30 degrees) telescope with a diameter of 2.5 meters and installed to International Space Station. Active researches are done in the fields of the development of super-high speed special purpose comuters and the large scale simulations of biomolecules and formation process of supermassive blackholes, computational materials science, science of earth and planets, and education with computers.
