论文摘要
电子在冲击波散射和向外加速时加速,然后从平面冲击的下游流中移动到射流的发射区域。当前的工作考虑了冲击阵线中电子的加速度。假设在冲击区域和下游区域之间的界面处有适当的边界条件,则在这项工作中提出了下游流中的新粒子分布,以重现Bl lac对象的宽带光谱能量分布。我们发现(1)我们可以在四种情况下获得冲击波下游的粒子分布; (2)具有较高能量的电子($γ>γ_{0} $)主导发射光谱; (3)我们模型中假定的明显重要的物理参数可以合理地重现高同步的BL LAC对象Markarian 421(MRK 421)的多波长光谱。
Electrons are accelerated at the shock wave diffuse and advect outward, and subsequently drift away into the emitting region of the jet that is located in the downstream flow from the plane shock. The current work considers the acceleration of the electrons in the shock front. Assuming a proper boundary condition at the interface between the shock and the downstream zones, a novel particle distribution in the downstream flow is proposed in this work to reproduce the broadband spectral energy distribution of BL Lac objects. We find that (1) we can obtain the particle distribution downstream of the shock wave in four cases; (2) electrons with higher energy ($γ>γ_{0}$) dominate the emission spectrum; (3) the distinctly important physical parameters assumed in our model can reasonably reproduce the multi-wavelength spectrum of the high-synchrotron-peaked BL Lac object Markarian 421 (Mrk 421).
