关于黑洞的面积量子化和回波

On Black Hole Area Quantization and Echoes

Andrew Coates, Sebastian H. Völkel, Kostas D. Kokkotas

摘要:

在这项工作中,我们认为,黑洞面积量子化的贝肯斯坦和Mukhanov不应该引起可测量的影响,在所谓的引力波回波在黑洞合并。我们概述了黑洞的量子谱应该在黑洞合并期间和之后被冲洗掉,因此在这种情况下不应该期望回声。光谱的极端加宽是由于衰荡期间的大粒子发射率。我们的研究结果质疑了最近文献中关于这一主题的关键假设。

英文摘要:

In this work we argue that black hole area quantization of Bekenstein and Mukhanov should not give rise to measurable effects in terms of so-called gravitational wave echoes during black hole mergers. We outline that the quantum spectrum of a black hole should be washed out during and after black hole mergers, and hence one should not expect echoes in this scenario. The extreme broadening of the spectrum is due to the large particle emission rate during ringdown. Our results question key assumptions being made in recent literature on this topic.
