论文摘要
测试黑洞的充电特性是修改后的重力和黑洞天体物理学的一个引人入胜的话题。在第一个重力波瞬态目录（GWTC-1）中，已经正式报道了十个二进制黑洞合并事件，并且这些引力波信号显着增强了我们对黑洞的理解。在本文中，我们试图通过将电荷作为贝叶斯的小扰动来限制用参数化的后源框架来限制电荷的量。我们发现，我们工作中的当前限制与以前的工作中Fisher Information Matrix方法的结果一致。考虑到二进制黑洞Inspiral的领先订单充电效应，我们还开发了波形模型。
Testing black hole's charged property is a fascinating topic in modified gravity and black hole astrophysics. In the first Gravitational-Wave Transient Catalog (GWTC-1), ten binary black hole merger events have been formally reported, and these gravitational wave signals have significantly enhanced our understanding of the black hole. In this paper, we try to constrain the amount of electric charge with the parameterized post-Einsteinian framework by treating the electric charge as a small perturbation in a Bayesian way. We find that the current limits in our work are consistent with the result of Fisher information matrix method in previous works. We also develop a waveform model considering a leading order charge effect for binary black hole inspiral.
