论文摘要
加速与宇宙弦相连的超级质量黑洞可能会导致结构形成，如果它们的速度很小，则会被星系捕获。这意味着这些黑洞的加速度也很小。如此缓慢的加速器对这种超大型黑洞的阴影没有显着影响。我们还表明，为了缓慢加速黑洞，引力透镜效应中图像的角度位置不会显着变化。我们提出了一种通过重力镜头观察这些黑洞加速的方法。该方法基于这样的观察结果，即与图像相关的差异时间延迟相对于非加速黑洞的情况大不相同。
Accelerating supermassive black holes, connected to cosmic strings, could contribute to structure formation and get captured by galaxies if their velocities are small. This would mean that the acceleration of these black holes is small too. Such a slow acceleration has no significant effect on the shadow of such supermassive black holes. We also show that, for slowly accelerating black holes, the angular position of images in the gravitational lensing effects do not change significantly. We propose a method to observe the acceleration of these black holes through the gravitational lensing. The method is based on the observation that differential time delays associated with the images are substantially different with respect to the case of non-accelerating black holes.
