In this second part of a two-part paper, we discuss numerical simulations of a head-on merger of two nonspinning black holes. We resolve the fate of the original two apparent horizons by showing that after intersecting, their world tubes “turn around” and continue backwards in time. Using the method presented in the first paper [Phys. Rev. D 084083 (2021)] to locate these surfaces, we resolve several such world tubes evolving and connecting through various bifurcations and annihilations. This also draws a consistent picture of the full merger in terms of apparent horizons, or more generally, marginally outer trapped surfaces (MOTSs). The MOTS stability operator provides a natural mechanism to identify MOTSs which should be thought of as black hole boundaries. These are the two initial ones and the final remnant. All other MOTSs lie in the interior and are neither stable nor inner trapped.

双黑洞合并过程中视界的最终命运。二、视界消失

在这篇由两部分组成的论文的第二部分中，我们讨论了两个非自旋黑洞正面合并的数值模拟。我们通过展示在相交后，它们的世界管“转向”并继续向后继续，来解决最初的两个明显视界的命运。使用第一篇论文 [ Phys. 牧师 D084083 (2021)] 为了定位这些表面，我们解析了几个这样的世界管道，这些管道通过各种分叉和湮灭演化和连接。这也从明显的视界，或更一般地说，边缘外被困表面 (MOTS) 方面绘制了完全合并的一致图景。MOTS 稳定性算子提供了一种自然机制来识别应被视为黑洞边界的 MOTS。这是最初的两个和最后的残余。所有其他 MOTS 都位于内部，既不稳定也不被困在内部。
