论文摘要
我们表明,重力波天文学有可能告知我们黑洞的量子方面。根据Bekenstein的量化,我们发现黑洞区域离散化可以从一对合并的黑洞中赋予重力波信号的可观察到的烙印,从而影响其在灵感中的吸收特性,并在合并后其后期放松。与以前的结果相反,我们发现天体物理学无处不在的黑洞旋转提高了我们探测量子效应的能力。我们的分析表明,重力波回声和抑制潮汐加热是新物理学的迹象,可以从中测量黑洞面积的基本量子,并且可以在未来的检测器中触及。我们的结果还强调了从特定的量子重力建议中得出预测的必要性。
We show that gravitational-wave astronomy has the potential to inform us on quantum aspects of black holes. Based on Bekenstein's quantization, we find that black hole area discretization could impart observable imprints to the gravitational-wave signal from a pair of merging black holes, affecting their absorption properties during inspiral and their late-time relaxation after merger. In contrast with previous results, we find that black hole rotation, ubiquitous in astrophysics, improves our ability to probe quantum effects. Our analysis shows that gravitational-wave echoes and suppressed tidal heating are signs of new physics from which the fundamental quantum of black hole area can be measured, and which are within reach of future detectors. Our results also highlight the need to derive predictions from specific quantum gravity proposals.
