| Research Abstract |
We have studied various particle acceleration processes in space and astrophysical extreme environments based on the newest theoretical and observational results toward the understanding of the long-lasting enigma about cosmic ray proton-electron ratio. As central topics, we have conducted researches on shock acceleration processes, and stochastic acceleration processes in turbulences, covering the earth’s bow shock, supernova remnant shocks, as well as relativistic shocks in gamma ray bursts. We have successfully contributed to the renewal of the understanding of acceleration processes for wide range of parameters.
