A general theory of linear cosmological perturbations: bimetric theories
Macarena Lagos, Pedro G. Ferreira
We implement the method developed in [1] to construct the most general parametrised action for linear cosmological perturbations of bimetric theories of gravity. Specifically, we c…

A general theory of linear cosmological perturbations: scalar-tensor and vector-tensor theories
Macarena Lagos, Tessa Baker, Pedro G. Ferreira +1
We present a method for parametrizing linear cosmological perturbations of theories of gravity, around homogeneous and isotropic backgrounds. The method is sufficiently general and…
