超新星遗迹与银河磁场的联系：轴对称样品准平行和准垂直cosmic ray加速度的分析
The connection between supernova remnants and the Galactic magnetic field: An analysis of quasi-parallel and quasi-perpendicular cosmic ray acceleration for the axisymmetric sample
摘要：
超新星遗迹中宇宙射线的加速机制是该领域的一个悬而未决的问题。我们使用准垂直和准平行宇宙射线电子（CRE）加速的情况下，32个轴对称信噪比的样本模型。轴对称样本被定义为包括具有双侧、双边形态的SNR，以及具有单侧形态的SNR，其中一个分支比另一个更亮。使用坐标变换技术，我们插入一个泡沫状的模型SNR到银河系磁场的模型。由于SNR的无线电发射主要由同步辐射控制，并且由于这种发射取决于磁场和CRE分布，因此我们能够模拟SNR发射并将其与数据进行比较。我们发现，准垂直的CRE加速度的情况下是更符合数据比准平行的CRE加速度的情况下，与G327.6+14.6（SN 1006）是一个显着的例外。我们建议，SN1006可能是一种情况下，准平行和准垂直加速度同时在一个单一的SNR中发挥作用。
英文摘要：
The mechanism for acceleration of cosmic rays in supernova remnants (SNRs) is an outstanding question in the field. We model a sample of 32 axisymmetric SNRs using the quasi-perpendicular and quasi-parallel cosmic-ray-electron (CRE) acceleration cases. The axisymmetric sample is defined to include SNRs with a double-sided, bilateral morphology, and also those with a one-sided morphology where one limb is much brighter than the other. Using a coordinate transformation technique, we insert a bubble-like model SNR into a model of the Galactic magnetic field. Since radio emission of SNRs is dominated by synchrotron emission and since this emission depends on the magnetic field and CRE distribution, we are able to simulate the SNRs emission and compare this to data. We find that the quasi-perpendicular CRE acceleration case is much more consistent with the data than the quasi-parallel CRE acceleration case, with G327.6+14.6 (SN1006) being a notable exception. We propose that SN1006 may be a case where both quasi-parallel and quasi-perpendicular acceleration are simultaneously at play in a single SNR.
