Testing General Relativity on cosmological scales and through screening mechanisms
If you have a question about this talk, please contact Camille Bonvin.
Future cosmological surveys, combining galaxy counts and weak lensing measurements, will map the evolution of matter perturbations and gravitational potentials from the matter dominated epoch until today. These measurements will enable us to test the relationships between matter overdensities, local curvature, and the Newtonian potential on cosmological scales. These relationships can be modified in alternative theories of gravity and by exotic forms of dark energy. I will discuss theoretical issues involved in finding an optimal framework to study deviations from GR on cosmological scales with focus on model-independend approaches. I will conclude with analysis of the Chameleon screening mechanisms around spheroidal sources and in dynamical configurations.
