我们使用Kastor-Traschen宇宙学多黑洞解计算碰撞黑洞的阴影，该解是描述具有正宇宙学常数的最大带电黑洞碰撞的精确解。我们发现，除了每个黑洞的阴影外，当黑洞彼此靠近时，还会出现眉毛状结构。这些特征可以作为探测器来发现处于合并过程最后阶段的多黑洞系统。
We compute the shadows of colliding black holes using the Kastor-Traschen cosmological multiblack hole solution that is an exact solution describing the collision of maximally charged black holes with a positive cosmological constant. We find that in addition to the shadow of each black hole, an eyebrowlike structure appears as the black holes come close to each other. These features can be used as probes to find the multiblack hole system at the final stage of its merger process.
