用地基探测器和脉冲星定时阵进行广义相对论的引力波检验

Gravitational Wave Tests of General Relativity with Ground-Based Detectors and Pulsar Timing Arrays

Nicolas Yunes, Xavier Siemens

摘要:

这篇评论的重点是测试爱因斯坦的广义相对论与引力波,可检测的地面干涉仪和脉冲星定时实验。爱因斯坦的理论在准线性、准静止状态下受到了很大的限制,在这种状态下,引力很弱,速度也很小。引力波将使我们能够探索一个互补的,但以前没有探索过的制度:非线性和动力学强场制度。例如,这样的状态适用于致密双星的合并,其中特征速度可以达到光速的50%,而致密度可以达到一半。本文从修正引力理论的理论基础和预测的引力波观测量开始。审查继续与探测器的简要说明,包括引力波干涉仪和脉冲星定时阵列,导致讨论的数据分析形式主义,适用于这种测试。最后讨论了对致密双星系统的引力波测试。

英文摘要:

This review is focused on tests of Einstein's theory of General Relativity with gravitational waves that are detectable by ground-based interferometers and pulsar timing experiments. Einstein's theory has been greatly constrained in the quasi-linear, quasi-stationary regime, where gravity is weak and velocities are small. Gravitational waves will allow us to probe a complimentary, yet previously unexplored regime: the non-linear and dynamical strong-field regime. Such a regime is, for example, applicable to compact binaries coalescing, where characteristic velocities can reach fifty percent the speed of light and compactnesses can reach a half. This review begins with the theoretical basis and the predicted gravitational wave observables of modified gravity theories. The review continues with a brief description of the detectors, including both gravitational wave interferometers and pulsar timing arrays, leading to a discussion of the data analysis formalism that is applicable for such tests. The review ends with a discussion of gravitational wave tests for compact binary systems.
