探测器网络对引力波源的三角测量

Triangulation of gravitational wave sources with a network of detectors

Stephen Fairhurst

摘要:

利用引力波和电磁观测进行多信使天文学将获得重大利益。为了对引力波信号进行电磁跟踪,有必要在天空中精确定位它们。由于引力波探测器本身不是指向仪器,定位主要通过探测器网络的三角测量来实现。我们调查所观察到的信号和本地化的后果的预期定时精度。此外,我们讨论了系统的不确定性的影响,在波形和校准的仪器上的定位源。我们提供了说明性的结果的定时和定位精度以及系统的影响合并二进制波形。

英文摘要:

There is significant benefit to be gained by pursuing multi-messenger astronomy with gravitational wave and electromagnetic observations. In order to undertake electromagnetic follow-ups of gravitational wave signals, it will be necessary to accurately localize them in the sky. Since gravitational wave detectors are not inherently pointing instruments, localization will occur primarily through triangulation with a network of detectors. We investigate the expected timing accuracy for observed signals and the consequences for localization. In addition, we discuss the effect of systematic uncertainties in the waveform and calibration of the instruments on the localization of sources. We provide illustrative results of timing and localization accuracy as well as systematic effects for coalescing binary waveforms.
