Outline of Final Research Achievements

We studied theoretically and observationally shock waves propagating into realistic upstream medium, which are seen in, for example, supernova remnants. We performed X-ray and gamma-ray observations, and gave theoretical interpretations for them. Galaxy clusters and gravitational wave events are also studied in the context of the cosmic-ray acceleration.
