引力波天文学有可能大大推进我们对宇宙的认识，从最强大的天体物理引擎到我们宇宙的初始阶段。引力波也携带着关于黑洞性质的信息。在这里，我们调查的引力波探测器的潜力，以测试由贝肯斯坦和Mukhanov的建议，黑洞视界的面积是量化的普朗克面积的单位。我们的研究结果表明，这种量子化可能对探测器接收到的经典引力波信号产生潜在的可观察影响。特别是，我们发现扭曲的引力波“回波”在合并后的波形描述的螺旋和合并的两个黑洞。这些回波具有特定的频率成分，这是黑洞视界面积量化的特征。
Gravitational-wave astronomy has the potential to substantially advance our knowledge of the cosmos, from the most powerful astrophysical engines to the initial stages of our universe. Gravitational waves also carry information about the nature of black holes. Here we investigate the potential of gravitational-wave detectors to test a proposal by Bekenstein and Mukhanov that the area of black hole horizons is quantized in units of the Planck area. Our results indicate that this quantization could have a potentially observable effect on the classical gravitational wave signals received by detectors. In particular, we find distorted gravitational-wave “echoes” in the post-merger waveform describing the inspiral and merger of two black holes. These echoes have a specific frequency content that is characteristic of black hole horizon area quantization.
