摘要两个黑洞的合并是自然界最不寻常的事件之一。这些空洞由纯重力组成，形成一个单独的空洞，释放出强烈的引力辐射。目前，地面探测器正在从双星演化过程中形成的空洞中寻找这样的爆发，实际上，检测到的第一个引力波事件很可能是黑洞的合并。空间LISA探测器的设计目的是在星系中心合并质量黑洞的过程中搜索这样的爆发，这些事件将在几分钟内释放出数千太阳质量的纯引力波能量。为了帮助引力波天文学家进行搜索，并能够理解他们所看到的细节，数值相对主义者正在对这些事件进行超级计算机模拟。我在这里回顾了这些模拟的最新技术状况，我们迄今从这些模拟中学到了什么，以及在我们对这些事件的预期波形进行全面预测之前仍然存在哪些挑战。
AbstractThe merger of two black holes is one of the most extraordinary events in the natural world. Made of pure gravity, the holes combine to form a single hole, emitting a strong burst of gravitational radiation. Ground-based detectors are currently searching for such bursts from holes formed in the evolution of binary stars, and indeed the very first gravitational wave event detected may well be a black-hole merger. The space-based LISA detector is being designed to search for such bursts from merging massive black holes in the centers of galaxies, events that would emit many thousands of solar masses of pure gravitational wave energy over a period of only a few minutes. To assist gravitational wave astronomers in their searches, and to be in a position to understand the details of what they see, numerical relativists are performing supercomputer simulations of these events. I review here the state of the art of these simulations, what we have learned from them so far, and what challenges remain before we have a full prediction of the waveforms to be expected from these events.
