用地面引力波探测器网络进行与模型无关的重力试验

Model-independent test of gravity with a network of ground-based gravitational-wave detectors

Kazuhiro Hayama, Atsushi Nishizawa

摘要:

利用先进的LIGO、先进的Virgo和KAGRA等干涉探测器组成的全球网络对引力波进行观测,将使探索时空结构的本质成为可能。除了爱因斯坦的广义相对论之外,到目前为止,还有几种引力理论通过了实验检验。引力波的观测提供了一个新的实验测试的替代理论的重力,因为引力波可能有最多六个独立的偏振模式,其属性和数量的模式依赖于引力理论。本文提出了一种从先进探测器网络的时间序列数据中重建独立偏振模式的方法。由于该方法不依赖于任何特定的模型,它给出了模型无关的测试替代理论的重力。

英文摘要:

The observation of gravitational waves with a global network of interferometric detectors such as advanced LIGO, advanced Virgo, and KAGRA will make it possible to probe into the nature of space-time structure. Besides Einstein's general theory of relativity, there are several theories of gravitation that passed experimental tests so far. The gravitational-wave observation provides a new experimental test of alternative theories of gravity because a gravitational wave may have at most six independent modes of polarization, of which properties and number of modes are dependent on theories of gravity. This paper proposes a method to reconstruct the independent modes of polarization in time-series data of an advanced detector network. Since the method does not rely on any specific model, it gives model-independent test of alternative theories of gravity.
