| Outline of Final Research Achievements |
The research program supported by this KAKENHI (C) grant was carried out successfully and has bore fruit in the form of a series of papers in refereed journals as well as two graduate students at Kyoto University being granted their Ph.D degrees in the year of 2022 and 2024 respectively. The grant has also been used to help supervise research projects by several domestic and overseas graduate students who have succeeded to obtain their Ph.D degrees during the KAKENHI (C) period as well. One could say this funding has contributed to both science of supernovae and supernova remnants (SNRs) as well as graduate school education for budding astrophysicists and researchers in tech companies. In terms of research, we have produced a consistent series of published results on topics such as hydro evolution of SNRs in various circumstellar environments, broadband emission modeling, cosmic ray and neutrino physics, astrophysical plasma and also development of next generation X-ray telescopes.

| Academic Significance and Societal Importance of the Research Achievements |
The research realized by this generous grant has shed light on multiple aspects of the theory of stellar evolution of massive stars, supernova explosion mechanisms, particle acceleration and so on as well as providing constraints on the development of future X-ray space telescopes.
