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 . Such a regime is, for example, applicable to compact binaries coalescing, where characteristic velocities can reach fifty percent the speed of light and gravitational fields are large and dynamical. 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.
本综述聚焦于利用地基干涉仪和脉冲星计时实验可探测到的引力波对爱因斯坦广义相对论进行的检验。爱因斯坦的理论在准线性、准静态区域受到了极大限制，在该区域中引力较弱且速度较小。引力波将使我们能够探索一个互补但此前未被探索的区域：非线性和动态区域。例如，这样的区域适用于致密双星合并，其中特征速度可达到光速的50%，引力场大且动态变化。本综述首先介绍修正引力理论的理论基础和预测的引力波可观测量。接着简要描述探测器，包括引力波干涉仪和脉冲星计时阵列，进而讨论适用于此类检验的数据分析形式。综述最后讨论致密双星系统的引力波检验。
