论文摘要
我们分析了在充电黑洞时分析黑洞二进制合并事件范围的形成和演变。我们发现，电荷的存在会影响合并的特性，可用于研究各种修饰的重力理论的有效性以及对候选暗物质的几项建议。此外，它可以为涉及黑洞的天体物理现象的各个方面提供洞察力，例如重力波参数测定中的变性。我们在分析和数值上进行分析，以$ d = 4 $尺寸，极高的质量比（EMR）限制并比较结果。鉴于LISA干涉仪即将进行的观察，EMR极限中的分析结果的发展至关重要。然后，我们使用我们的分析来描述合并期间的时间表的时间如何演变，并研究事件视野区域和合并持续时间的增长。此外，我们提供了一个在任意维度上有效的数值解决方案$ d \ geq 4 $，这在ADS/CFT通信或检查可能的一般相对性扩展的情况下可能会引起人们的关注。
We analyse the formation and evolution of the event horizon of a black hole binary merger when the black holes are charged. We find that the presence of charge influences the properties of the merger and can be useful for investigating the validity of various theories of modified gravity and several proposals for dark matter candidates. It can moreover give insights into various aspects of astrophysical phenomena involving black holes, such as degeneracies in the gravitational wave parameter determination. We perform our analysis both analytically and numerically, in $D=4$ dimensions, in the Extreme Mass Ratio (EMR) limit and compare the results. The development of analytical results in the EMR limit is of uttermost importance in view of the upcoming observations of the LISA interferometer. We then use our analysis to describe how the horizon evolves in time during the merger and to investigate the growth in the area of the event horizon and the duration of the merger. We moreover provide a numerical solution valid in arbitrary dimensions $D \geq 4$ which could be of interest in the context of the AdS/CFT correspondence or for examining possible extensions of general relativity.
