معرفی
Ryuichiro Akaho is a tenure-track Assistant Professor in the Faculty of Science and Engineering, School of Advanced Science and Engineering at Waseda University, Japan. He earned his B.S., M.S., and Ph.D. in physics from the same university and is internationally recognized for developing general-relativistic Boltzmann neutrino transport codes applied to core-collapse supernovae and neutron-star cooling.
Education:
- Ph.D. in Science, Waseda University, 2021–2024
- M.S. in Advanced Science and Engineering, Waseda University, 2019–2021
- B.S. in Advanced Science and Engineering (Physics), Waseda University, 2015–2019
Research Interests:
Akaho’s theoretical work centers on neutrino radiation hydrodynamics in extreme astrophysical environments. He investigates how neutrinos drive supernova explosions, how flavor oscillations modify neutrino spectra, and how fallback accretion affects late-time neutrino emission from protoneutron stars. His simulations incorporate full general relativity, multidimensional transport, and state-of-the-art nuclear physics inputs.
His recent studies reveal the universality of collisional flavor instabilities and quantify the detectability of supernova neutrinos by experiments such as Super-Kamiokande. These results bridge nuclear physics, high-energy astrophysics, and multimessenger astronomy.
Awards & Honors:
- Young Scientist Presentation Award, Asia Nuclear Physics Association, 2025
