自发洛伦兹破坏引起的颠簸黑洞

Bumpy black holes from spontaneous Lorentz violation

Sergei Dubovsky, Peter Tinyakov, Matias Zaldarriaga

摘要:

我们考虑洛伦兹破坏大质量引力理论中的黑洞。我们认为,在这些理论中,黑洞解不再是普遍的,并表现出大量的头发。如果它们存在的话,这些毛发将探测黑洞内部的奇点,为我们提供一个了解量子引力的窗口。未来的引力波观测站可以检验这些毛发的存在。我们一般认为,对于质量更大的黑洞,我们讨论的效应会更大。在最简单的模型中,毛发的强度由设置引力子质量的相同参数控制(张量模式)。然后,这个质量的上限来自于双星发射的引力辐射,这意味着星系中心的超大质量黑洞的几乎整个质量范围内的头发都可能被抑制。

英文摘要:

We consider black holes in Lorentz violating theories of massive gravity. We argue that in these theories black hole solutions are no longer universal and exhibit a large number of hairs. If they exist, these hairs probe the singularity inside the black hole providing a window into quantum gravity. The existence of these hairs can be tested by future gravitational wave observatories. We generically expect that the effects we discuss will be larger for the more massive black holes. In the simplest models the strength of the hairs is controlled by the same parameter that sets the mass of the graviton (tensor modes). Then the upper limit on this mass coming from the inferred gravitational radiation emitted by binary pulsars implies that hairs are likely to be suppressed for almost the entire mass range of the super-massive black holes in the centers of galaxies.
