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…

Galileon Gravity in Light of ISW, CMB, BAO and $H_{0}$ data

Janina Renk, Miguel Zumalacárregui, Francesco Montanari +1

Cosmological models with Galileon gravity are an alternative to the standard $Λ CDM$ paradigm with testable predictions at the level of its self-accelerating solutions for the…

Response Approach to the Matter Power Spectrum Covariance

Alexandre Barreira, Fabian Schmidt

We present a calculation of the matter power spectrum covariance matrix $Cov (k_{1}, k_{2})$ that uses power spectrum responses to accurately describe the coupling betwee…
