Cosmic rays are high-energy particles that come from outer space, but where they come from is one of the greatest questions in astrophysics. The International Center for Hadron Astrophysics, or ICEHAP, was established in 2012 with two divisions, Neutrino Astronomy and Plasma Astrophysics. ICEHAP’s goal is to gain a clearer understanding of the sources of high-energy cosmic ray hadrons (such as protons and neutrons) and the mechanisms behind particle acceleration, through collaboration with researchers searching for cosmic neutrinos and researchers conducting theoretical simulations of the phenomena associated with the activity observed around astronomical objects. In 2020, ICEHAP was reorganized as an independent university center, and it is now one of Chiba University’s flagship research facilities, promoting research and education.
