Power of Weak Lensing in Constraining Modified Matter and Gravity Theories
Camera, Stefano (CENTRA, Istituto Superior Técnico, Lisboa)

I present how weak gravitational lensing effects can be used to test and constrain alternative cosmological models. Specifically, I show the promising results obtained by applying the cosmic shear statistics to three alternative cosmologies. These models, which well represent the landscape of modified matter and gravity theories, are: 1) a model of unified DM and DE; 2) a phenomenological extension of the DGP brane-world; and 3) two viable modified-action f(R) Lagrangians.
