合并致密双星产生的引力波

Gravitational waves from merging compact binaries

Scott A. Hughes

摘要:

近年来,由于高灵敏度引力波探测器的发展,我们对合并致密双星及其产生的引力波的理解有了很大的提高。数值相对论的突破性进展使我们能够模拟两个黑洞的合并,而无需近似或简化。在我们对二进制的分析理解方面也取得了显著的进展。我们回顾这些发展,检查合并二进制使用黑洞微扰理论,后牛顿展开,并直接数值积分的场方程。我们总结了这些方法和他们教我们的引力波从紧凑的双星。我们将这些结果放在引力波产生系统的背景下,分析引力波发射对其源的影响,以及我们可以从直接引力波测量中了解到什么。

英文摘要:

Largely motivated by the development of highly sensitive gravitational-wave detectors, our understanding of merging compact binaries and the gravitational waves they generate has improved dramatically in recent years. Breakthroughs in numerical relativity now allow us to model the coalescence of two black holes with no approximations or simplifications. There has also been outstanding progress in our analytical understanding of binaries. We review these developments, examining merging binaries using black hole perturbation theory, post-Newtonian expansions, and direct numerical integration of the field equations. We summarize these approaches and what they have taught us about gravitational waves from compact binaries. We place these results in the context of gravitational-wave generating systems, analyzing the impact gravitational wave emission has on their sources, as well as what we can learn about them from direct gravitational-wave measurements.
