论文摘要
在这项工作中，我们研究了带有磁性单孔的黑洞和浸入BI统一磁场中的Schwarzschild黑洞的阴影。通过使用向后的射线追踪方法获得黑洞图像，由天体球照明。对于磁性带电的BI黑洞，我们发现阴影半径随着非线性电磁效应的增加而增加。对于浸入BI均匀磁场的Schwarzschild黑洞，光子倾向于向对称的轴移动，从而沿赤道平面产生伸展的阴影。
In this work, we study the shadow of Born-Infeld (BI) black holes with magnetic monopoles and Schwarzschild black holes immersed in the BI uniform magnetic field. Illuminated by a celestial sphere, black hole images are obtained by using the backward ray-tracing method. For magnetically charged BI black holes, we find that the shadow radius increases with the increase of nonlinear electromagnetics effects. For Schwarzschild black holes immersed in the BI uniform magnetic field, photons tend to move towards the axis of symmetric, resulting in stretched shadows along the equatorial plane.
