Study of Cosmic Ray p/e Ratio based on Shock Acceleration Theory

我们基于最新的理论和观测结果，研究了空间和天体物理极端环境中的各种粒子加速过程，以了解宇宙线质子电子比这个长期存在的谜团。作为中心课题，我们对冲击加速过程和湍流中的随机加速过程进行了研究，包括地球的弓形冲击、超新星残余冲击以及伽马射线暴中的相对论冲击。我们已经成功地为更新对大范围参数的加速过程的理解做出了贡献。

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.
