论文摘要
使用本征函数扩展来解决传输方程，并在蒙特卡洛模拟的互补中互补，我们表明，即使在下游等离子体中未能产生较大的振幅湍流时，超级层次的冲击也可能是有效的粒子加速器。这一发现与普遍认为的信念相矛盾，即垂直于休克正常的均匀下游磁场通过一阶费米工艺抑制加速度。在超级层次的极限中，我们发现这些冲击的固定幂律粒子谱S = 4.17，接近预测的严格平行冲击。
Using an eigenfunction expansion to solve the transport equation, complemented by Monte-Carlo simulations, we show that ultrarelativistic shocks can be effective particle accelerators even when they fail to produce large amplitude turbulence in the downstream plasma. This finding contradicts the widely held belief that a uniform downstream magnetic field perpendicular to the shock normal inhibits acceleration by the first order Fermi process. In the ultrarelativistic limit, we find a stationary power-law particle spectrum of index s=4.17 for these shocks, close to that predicted for a strictly parallel shock.
