A general theory of linear cosmological perturbations: stability conditions, the quasistatic limit and dynamics
Macarena Lagos, Emilio Bellini, Johannes Noller +2
We analyse cosmological perturbations around a homogeneous and isotropic background for scalar-tensor, vector-tensor and bimetric theories of gravity. Building on previous results,…
Strong constraints on cosmological gravity from GW170817 and GRB 170817A
Tessa Baker, Emilio Bellini, Pedro G. Ferreira +3
The detection of an electromagnetic counterpart (GRB 170817A) to the gravitational wave signal (GW170817) from the merger of two neutron stars opens a completely new arena for test…
A comparison of Einstein-Boltzmann solvers for testing General Relativity
E. Bellini, A. Barreira, N. Frusciante +24
We compare Einstein-Boltzmann solvers that include modifications to General Relativity and find that, for a wide range of models and parameters, they agree to a high level of preci…
