Luminal Propagation of Gravitational Waves in Scalar-tensor Theories: The Case for Torsion
José Barrientos, Fabrizio Cordonier-Tello, Cristóbal Corral +4
Scalar-tensor gravity theories with a nonminimal Gauss-Bonnet coupling typically lead to an anomalous propagation speed for gravitational waves, and have therefore been tightly con…
Wave Operators, Torsion, and Weitzenböck Identities
José Barrientos, Fernando Izaurieta, Eduardo Rodríguez +1
We offer a mathematical toolkit for the study of waves propagating on a background manifold with nonvanishing torsion. Examples include electromagnetic and gravitational waves on a…
Linear and Second-order Geometry Perturbations on Spacetimes with Torsion
Fernando Izaurieta, Eduardo Rodríguez, Omar Valdivia
In order to study gravitational waves in any realistic astrophysical scenario, one must consider geometry perturbations up to second order. Here, we present a general technique for…
