论文摘要
在这项工作中，我们得出了两个编码在几何光学近似下弯曲时空中移动电子的同步辐射的极化方向和光度的公式。作为一种应用，我们进一步研究了带有垂直和均匀磁场的Schwarzschild黑洞时空中电子源的同步辐射的极化图像。特别是，通过关注赤道平面上电子的圆形轨道，我们显示了来自这些轨道的同步辐射的偏振图像，这些轨道具有不同的观察角，并讨论了有关角度的极化方向的变化。
In this work, we derive two formulas encoding the polarization direction and luminosity of synchrotron radiations from the moving electrons in curved spacetime under the geometric optics approximation. As an application, we further study the polarized images of synchrotron radiations from electron sources in Schwarzschild black hole spacetime with a vertical and uniform magnetic field. In particular, by focusing on the circular orbits of electrons on the equatorial plane, we show the polarized images of the synchrotron radiations from these orbits for different observational angles and discuss the variations of the polarization directions concerning the angles.
