论文摘要
所谓的C-Metric描述了加速黑洞。在这项工作中,我们通过使用无效的测量学分析了这种黑洞的因果结构。我们明确构建相关的彭罗斯图。首先,我们恢复了与亚加速黑洞有关的众所周知的结果。然后,我们将研究扩展到超级加速案例,其中出现了其他必要的奇异性。此外,我们考虑加速具有负质量的黑洞。我们表明它们等同于通过保形无穷大的黑洞指标描述的几何形状。我们将结果与Schwarzschild几何形状进行比较,以促进并突出新功能的兴趣。
Accelerating black holes are described by the so-called C-metric. In this work, we analyse the causal structure of such black holes by using null geodesics. We construct explicitly the relevant Penrose diagrams. First, we recover well-known results associated with the sub-accelerating black holes. Then, we extend the study to the super-accelerating case, in which an additional essential singularity appears. In addition, we consider accelerating black holes with negative masses. We show that they are equivalent to the geometry described by the black hole metric beyond conformal infinity. We compare our results with the Schwarzschild geometry to facilitate understanding and to highlight the interest of the new features.
