|Outline of Final Research Achievements
Multi-messenger astronomy that observes the universe using particles in addition to photons has finally begun with a full-fledged scale. During the grant period, there are (1) the first detection of gravitational waves (2) rapid growth in high energy neutrino events (3) progress in observations of positron, antiproton and helium cosmic rays. In these circumstances, I made various theoretical contributions. In particular, (a) proposal of an off-axis jet model of the gamma-ray burst associated with the gravitational wave GW170817 (b) limitations on neutrino interactions (c) development of our chemically-inhomogeneous model in which the cosmic-ray spectrum bends due to the spatial non-uniformity of the elements.
