Practical solutions for perturbed f(R) gravity
Alireza Hojjati, Levon Pogosian, Alessandra Silvestri +1
We examine the accuracy of the quasi-static approximation and a parametric form commonly employed for evolving linear perturbations in f(R) gravity theories and placing cosmologica…

Degeneracies in parametrized modified gravity models
Alireza Hojjati
We study degeneracies between parameters in some of the widely used parametrized modified gravity models. We investigate how different observables from a future photometric weak le…
