  • We present a set of predictions for weak lensing correlation functions in the context of modified gravity models, including a prescription for the impact of the non-linear power spectrum regime in these models. We consider the Dvali, Gabadadze & Porrati and f(R) models, together with dark energy models with the same expansion history. We use the requirement that gravity is close to general relativity on small scales to estimate the non-linear power for these models. We then calculate weak… CONTINUE READING
