用先进的引力波探测器网络进行源定位

Source localization with an advanced gravitational wave detector network

Stephen Fairhurst

摘要:

我们推导出一个表达式的准确性与源可以使用网络的引力波探测器本地化。结果是通过三角测量,使用定时精度在每个检测器,并适用于任何数量的检测器的网络。我们使用这个结果来研究先进的引力波探测器网络的能力,以准确地定位信号从紧凑的二元聚结。我们证明,额外的探测器可以显着提高定位结果,并说明我们的研究结果与网络组成的先进的LIGO,先进的处女座和LCGT。此外,我们还评估了将一个先进的LIGO探测器搬迁到澳大利亚的好处。

英文摘要:

We derive an expression for the accuracy with which sources can be localized using a network of gravitational wave detectors. The result is obtained via triangulation, using timing accuracies at each detector and is applicable to a network with any number of detectors. We use this result to investigate the ability of advanced gravitational wave detector networks to accurately localize signals from compact binary coalescences. We demonstrate that additional detectors can significantly improve localization results and illustrate our findings with networks comprised of the advanced LIGO, advanced Virgo and LCGT. In addition, we evaluate the benefits of relocating one of the advanced LIGO detectors to Australia.
