标题： Spectral energy distribution, polarization, and synthetic radio maps of Cygnus X-1: a lepto-hadronic jet model

摘要： 在这项工作中，我们结合SED（能谱分布）、射电图以及偏振观测来理解天鹅座X-1中的辐射机制。 我们的辐射模型表明，MeV辐射起源于喷流，且所有超高能辐射均来自强子起源。 我们还生成了一个综合的射电图，这表明我们需要改进对磁场的描述，因为它导致了非常紧凑的辐射区域。 为了选择最合适的磁场几何结构，我们研究了X射线中的偏振现象，并发现非常简单的几何结构可以解释其他作者报告的高水平偏振现象。 显示英文摘要

摘要： In this work we combine SEDs, radio maps and polarization observations to understand the emission mechanisms in Cygnus X-1. Our radiative model indicates that the MeV emission originates in the jet and that all the very high-energy emission is from hadronic origin. We also performed a synthetic radio map that suggests that our description of the magnetic field should be improved, since it leads to a very compact emission region. In order to choose the most suitable magnetic field geometry, we investigated the polarization in X-rays and we found that very simple geometries can explain the high levels of polarization reported by other authors.
