Description
Massive spin-2 fields naturally arise in various extensions of General Relativity, including massive bigravity and Kaluza-Klein models. This presentation explores the observational signatures of these hidden gravitons that can work as dark matter. In particular, we pay attention to the phenomenology associated with the propagation of gravitational waves. Within a phenomenological framework, we model the interaction between massless and massive tensor modes, leading to an oscillation phenomenon.
