标题： Modelling of Nonthermal Microwave Emission From Twisted Magnetic Loops

摘要： 利用最近开发的 GX 模拟工具对由扭曲磁环中的非热电子产生的微波回旋同步辐射无线电发射进行了建模。 我们考虑了各向同性和各向异性投掷角分布。 这项工作的主要目的是了解磁场扭曲拓扑对产生的无线电发射图的影响。 我们发现，扭曲磁环内的非热电子会产生具有特殊极化分布的回旋同步辐射无线电发射。 极化符号反转线相对于环轴倾斜。 考虑到非热电子的各向异性投掷角分布，在较不扭曲的环中，无线电发射源更为紧凑。 显示英文摘要

摘要： Microwave gyrosynchrotron radio emission generated by nonthermal electrons in twisted magnetic loops is modelled using the recently developed simulation tool GX Simulator. We consider isotropic and anisotropic pitch-angle distributions. The main scope of the work is to understand impact of the magnetic field twisted topology on resulted radio emission maps. We have found that nonthermal electrons inside twisted magnetic loops produce gyrosynchrotron radio emission with peculiar polarization distribution. The polarization sign inversion line is inclined relatively to the axis of the loop. Radio emission source is more compact in the case of less twisted loop, considering anisotropic pitch-angle distribution of nonthermal electrons.
