摘要 (Abstract): 

Gravitational wave (GW) observations offer a powerful tool for testing the fundamental Lorentz and parity symmetries of gravity. Any violation of these symmetries could manifest as deviations in GW propagations.In this talk, l will explore how current and future GW detections can be used to constrain Lorentz- and parity-violating effects in gravity. l will begin by introducing a systematic parameterization framework to describe potential deviations in GW propagation from general relativity in a cosmological background. Using this framework, we can construct modified GW waveforms, incorporating the effects of Lorentz and parity violations as predicted by various alternative gravity theories. Finally, l will present the latest results from our analysis of these modified wave forms using current GW data and discuss the prospects for placing even stronger constraints from future GW detections.
