重力与引力波的参数化一致性检验:现状与展望

Parameterized and Consistency Tests of Gravity with Gravitational Waves: Current and Future

Zack Carson, Kent Yagi

摘要:

引力波观测提供了独特的机会,以探测强和动态的制度,这是很难进入以前的重力。本文综述了用引力波检验广义相对论的两种理论不可知的方法,即(i)参数化波形检验和(ii)螺旋和合并振铃部分之间的一致性检验。对于每种方法,我们解释了形式主义,其次是现有事件的结果,最后我们讨论了升级探测器的未来前景,包括使用多波段引力波观测与地面和星载干涉仪的可能性。我们表明,这样的未来的观察有可能改善后,目前的界限理论超越广义相对论的许多数量级。最后,我们列出了几个有待解决的未决问题。

英文摘要:

Gravitational wave observations offer unique opportunities to probe gravity in the strong and dynamical regime, which was difficult to access previously. We here review two theory-agnostic ways to carry out tests of general relativity with gravitational waves, namely (i) parameterized waveform tests and (ii) consistency tests between the inspiral and merger-ringdown portions. For each method, we explain the formalism, followed by results from existing events, and finally we discuss future prospects with upgraded detectors, including the possibility of using multi-band gravitational-wave observations with ground-based and space-borne interferometers. We show that such future observations have the potential to improve upon current bounds on theories beyond general relativity by many orders of magnitude. We conclude by listing several open questions that remain to be addressed.
