Observation of the growth of a magnetic vortex in the transition layer of a mildly relativistic oblique plasma shock
摘要：
二维粒子模拟模拟了两个电子-离子等离子体云沿准平行磁场的碰撞。碰撞速度为0.9c，密度比为10。在稠密云的前部形成电流片，其中电子和磁场与离子达到能量均分。由螺线管和环形磁场组成的结构在该薄片中生长。它类似于无力球斑的环面横截面，可以提供伽马射线暴（GRB）喷流中快速发射所需的相干磁场。
英文摘要：
A 2D particle simulation models the collision of two electron-ion plasma clouds along a quasi-parallel magnetic field. The collision speed is 0.9c and the density ratio 10. A current sheet forms at the front of the dense cloud, in which the electrons and the magnetic field reach energy equipartition with the ions. A structure composed of a solenoidal and a toroidal magnetic field grows in this sheet. It resembles that in the cross-section of the torus of a force-free spheromak, which may provide the coherent magnetic fields in gamma-ray burst (GRB) jets needed for their prompt emissions.
