Gravitational waves (GWs) provide a new tool to probe the nature of dark energy (DE) and the fundamental properties of gravity. We review the different ways in which GWs can be used to test theories of gravity and cosmology, emphasizing models for late-time cosmic acceleration. Lagrangian-based grav...
