The astrophysical stochastic background of gravitational waves and detection by advanced high optical power interferometers: an Australia-US collaboration

该计划的目的是使先进的LIGO能够探测到引力波频谱中最令人兴奋和研究最少的组成部分之一——天体物理引力波背景（AGB）。它将扩展澳大利亚和美国在先进LIGO方面的合作，包括AGB的建模、仿真和检测方法，以及LIGO和先进LIGO类型系统中光学噪声的研究。特别是，我们计划寻找异常噪声源，特别是那些在高光功率腔中产生的可能限制AGB检测的噪声源。

The proposed project is designed to enable one of the most exciting and least studied components of the gravitational wave spectrum, the Astrophysical Gravitational wave Background (AGB), to be detected by Advanced LIGO. It will extend the Australia-US collaboration in Advanced LIGO to include modeling, simulation and detection methods of the AGB and the study of the optical noise in LIGO and Advanced LIGO type systems. In particular we plan to search for anomalous noise sources and, especially those arising in high optical power cavities that could limit detection of the AGB.
