Research Abstract

Relativistic particles generated in the course of relativistic magnetic reconnection is subject to the synchrotron radiation loss, because the strong magnetic field is needed to confine the relativistic hot plasma in the plasma sheet. The nonlinear dynamics and its particle acceleration is investigated by means of a relativistic electro-magnetic, particle-in-cell code, in which the synchrotron radiation effect is implemented. As a result, we found that fast magnetic reconnection can occur by the feedback effect of the reduction of gas pressure due to the radiation loss. In addition to the above isolated reconnection system, we also studied the complex system with multiple magnetic islands, and found that the efficiency of particle acceleration is dramatically improved.
