Abstract

Magnetic reconnection in strongly magnetized astrophysical plasma environments is believed to be the primary process for fast energy release and particle energization. Currently there is strong interest in relativistic magnetic reconnection, in that it may provide a new explanation for high-energy particle acceleration and radiation in strongly magnetized astrophysical systems. We review recent advances in particle acceleration and reconnection physics in the magnetically-dominated regime. More discussion is focused on the physics of particle acceleration, power-law formation as well as the reconnection rate problem. In addition, we provide an outlook for studying reconnection acceleration mechanisms and kinetic physics in the next step.

磁主导相对论区磁重联过程中粒子加速和重联物理学的最新进展

在强磁化的天体物理等离子体环境中，磁重联被认为是快速能量释放和粒子能量化的主要过程。目前，人们对相对论性磁重联有着浓厚的兴趣，因为它可能为强磁化天体物理系统中的高能粒子加速和辐射提供新的解释。我们回顾了磁主导下粒子加速和重联物理的最新进展。更多的讨论集中在粒子加速的物理，幂律的形成以及重连率问题。此外，对下一步重连加速机理和动力学物理的研究进行了展望。
