摘要:

数值相对论的最新进展使我们能够模拟二元黑洞合并问题的非微扰合并阶段。基于这些结果,我们提出了一个唯象的波形,它可以模拟黑洞合并的inspiral,合并和衰荡阶段。我们还构建了一个模板银行使用这个家庭的波形,并讨论其实施中的搜索签名的引力波产生的黑洞合并的地面干涉仪的数据。这个模板库可能使我们能够将目前的螺旋搜索扩展到更高质量的二元黑洞系统,即,这些系统的总质量大于约80个太阳质量,从而扩大了目前这一代地基探测器的探测范围。

英文摘要:

Recent progress in numerical relativity has enabled us to model the non-perturbative merger phase of the binary black-hole coalescence problem. Based on these results, we propose a phenomenological family of waveforms which can model the inspiral, merger, and ring-down stages of black hole coalescence. We also construct a template bank using this family of waveforms and discuss its implementation in the search for signatures of gravitational waves produced by black-hole coalescences in the data of ground-based interferometers. This template bank might enable us to extend the present inspiral searches to higher-mass binary black-hole systems, i.e., systems with total mass greater than about 80 solar masses, thereby increasing the reach of the current generation of ground-based detectors.
