Testing General Relativity with Gravitational Waves: An Overview

Understand

The detections of gravitational-wave (GW) signals from compact binary coalescence by ground-based detectors have opened up the era of GW astronomy.

• These observations provide opportunities to test Einstein's general theory of relativity at the strong-field regime.
• Here we give a brief overview of the various GW-based tests of General Relativity (GR) performed by the LIGO-Virgo collaboration on the detected GW events to date.
• After providing details for the tests performed in four categories, we discuss the prospects for each test in the context of future GW detectors.
