Gravitational waves in f(Q) gravity

The evolution of gravitational waves (GWs) in f(Q) gravity, whose foundation is the non-metricity (NM) scalar Q, has been examined in this study. We discuss and study the dynamics of the background evolution of GWs in a flat FRW universe. Two distinct f(Q) toy models are considered for the work. The perturbed equations controlling the evolution of GWs in terms of redshift z have been derived in the FRW Universe backdrop using the field equations. We then explored the properties of GWs within the paradigm of f(Q) gravity and obtained some intriguing conclusions.
