论文摘要
最近从2017年Blazar TXS 〜0506+056的高能中微子以及整个电磁频谱中的对应物中观察到的高能中微子，为研究了这类物体以及遍历的介质开辟了新的可能性。传播效应，例如众所周知，诸如胶外背景光对非常高的能量伽马射线成分的衰减是众所周知的，并且通常在拟合物体的光谱能量分布时考虑到。然而，其他效果（例如白术磁场的影响）经常被忽略。在这项工作中，我们介绍了这些领域的影响以及对确定该蓝azar固有伽玛射线频谱的影响的全面研究。
The recent observation of high-energy neutrinos from the 2017 flare of the blazar TXS~0506+056, together with counterparts across the whole electromagnetic spectrum, opens up new possibilities for investigating the properties of this class of objects as well as the traversed medium. Propagation effects such as the attenuation of the very-high-energy gamma-ray component by the extragalactic background light are well known, and usually taken into account when fitting spectral energy distributions of objects. Other effects such as those of intergalactic magnetic fields are, however, often neglected. In this work, we present a comprehensive study of the influence of these fields and the extragalactic background light on the determination of the intrinsic gamma-ray spectrum of this blazar.
