天空中的量子黑洞

Quantum Black Holes in the Sky

Jahed Abedi, Niayesh Afshordi, Naritaka Oshita, Qingwen Wang

摘要:

黑洞可能是我们宇宙中最神秘的物体。从它们在合并时的引力波中被探测到,到它们在星系中心的快照,黑洞天体物理学在过去的4年里经历了观测的复兴。尽管如此,它们仍然是强引力和量子效应的活跃场所,难以捉摸的量子引力理论的新方面可能正在努力工作。在这篇评论文章中,我们提供了一个强大的动机,为什么“量子黑洞“可能是从根本上不同于爱因斯坦的广义相对论的经典同行的概述。然后,我们讨论了量子黑洞的观测特征,重点是引力波回波作为量子视界(或奇异的紧凑物体)的吸烟枪,这导致了显着的最近的兴奋和活动。我们回顾了引力波回波的理论基础,并批判性地研究了关于它们(不)存在的看似矛盾的观测声明。最后,我们讨论了未来的理论和观测景观解开“量子黑洞在天空中”。

英文摘要:

Black Holes are possibly the most enigmatic objects in our Universe. From their detection in gravitational waves upon their mergers, to their snapshot eating at the centres of galaxies, black hole astrophysics has undergone an observational renaissance in the past 4 years. Nevertheless, they remain active playgrounds for strong gravity and quantum effects, where novel aspects of the elusive theory of quantum gravity may be hard at work. In this review article, we provide an overview of the strong motivations for why "Quantum Black Holes" may be radically different from their classical counterparts in Einstein's General Relativity. We then discuss the observational signatures of quantum black holes, focusing on gravitational wave echoes as smoking guns for quantum horizons (or exotic compact objects), which have led to significant recent excitement and activity. We review the theoretical underpinning of gravitational wave echoes and critically examine the seemingly contradictory observational claims regarding their (non-)existence. Finally, we discuss the future theoretical and observational landscape for unraveling the "Quantum Black Holes in the Sky".
