论文摘要
我们考虑了带有U（1）电荷的黑洞的两体动力捕获，这不仅可以与电荷或磁性电荷相对应，而且还具有其他物理解释，例如暗或隐藏电荷。在低速和弱场状态下，我们研究了来自双曲线轨道中U（1）电荷的点质量的引力和电磁辐射，并且我们开发了一种形式主义，以从两体动力学捕获中得出带电的黑洞的合并速率。我们将形式主义应用于可能的不同情况下，找到电荷与质量比对合并率的影响，并发现效果取决于模型。
We consider the two-body dynamical capture of black holes carrying U(1) charge which can not only correspond to electric or magnetic charge but also have other physical interpretations such as dark or hidden charge. In the low-velocity and weak-field regime, we study gravitational and electromagnetic radiations from point masses with U(1) charges in a hyperbolic orbit, and we develop a formalism to derive the merger rate of charged black holes from the two-body dynamical capture. We apply the formalism to find the effects of the charge-to-mass ratio on the merger rate for possible different cases and discover that the effects depend on the models.
