论文摘要
我们讨论在磁磁层的磁化对等离子体中运行的连贯的游离电子激光器（FEL）。该模型解释了快速无线电爆发/磁铁的无线电发射的许多显着特征：无线电和高能量爆发的时间巧合，等离子体动能转化为相干辐射的高效率，存在可变的，窄带发射的特征，频率下降，线性极高的极度降低。该模型依赖于磁铁特异性的漂移$ e^\ pm $等离子体成分（由于消防不稳定性的发展而产生摇摆的磁场），并且存在重新连接生成的粒子梁，而温和的lorentz因子为$γ_b\ sim $ sim $ $ $ $ lorentz。
We discuss coherent free electron laser (FEL) operating during explosive reconnection events in magnetized pair plasma of magnetar magnetospheres. The model explains many salient features of Fast Radio Bursts/magnetars' radio emission: temporal coincidence of radio and high energy bursts, high efficiency of conversion of plasma kinetic energy into coherent radiation, presence of variable, narrow-band emission features drifting down in frequency, high degree of linear polarization. The model relies on magnetar-specific drifting $e^\pm$ plasma components (which generate wiggler field due to the development of the firehose instability) and the presence of reconnection-generated particle beam with mild Lorentz factor of $γ_b \sim$ few hundred.
