摘要:

我们启动了一项关于黑洞引力辐射散射修正的引力波特征的普遍性研究。这类修正可能源于使黑洞与量子力学相容的量子动力学,或存在于其他偏离经典黑洞行为的模型中。我们提出将散射修正参数化,作为连接问题理论与观测层面的物理上有意义、与模型无关且实用的桥梁;该参数化方案可涵盖文献中的不同模型。随后我们描述了这些修正如何影响引力波信号,例如一个天体绕一个质量大得多的黑洞运动时产生的信号。特别是,它们通常会改变能量发射速率;这一效应可在旋近过程的多个轨道上累积利用,从而增强对小修正的灵敏度,这一点已在简单模型中被注意到。我们对未来引力波观测对这些修正的灵敏度给出了初步估计,并概述了进一步需要开展的工作,以便同时联系更基本的量子黑洞理论和现实的观测情境。

英文摘要:

We initiate a general investigation into gravitational wave signatures of modifications to scattering of gravitational radiation from black holes. Such modifications may be present due to the quantum dynamics that makes black holes consistent with quantum mechanics, or in other models for departures from classical black hole behavior. We propose a parameterization of the corrections to scattering as a physically meaningful, model-independent, and practical bridge between theoretical and observational aspects of the problem; this parameterization can incorporate different models in the literature. We then describe how these corrections influence the gravitational wave signal, e.g. of a body orbiting a much more massive black hole. In particular, they generically change the rate of energy emission; this effect can be leveraged over many orbits of inspiral to enhance the sensitivity to small corrections, as has been noticed in simple models. We provide preliminary estimates of the sensitivity of future gravitational wave observations to these corrections, and outline further work to be done to connect both to a more fundamental theory of quantum black holes, and to realistic observational situations.
