Description
In this work we reflect on the departure from the standard growth of structures induced by two seemingly different, yet comparable extensions to the standard cosmological model: modified gravity and massive neutrinos. Can current Cosmic Microwave Background anisotropy and lensing data tell the difference between a phenomenological modification in the growth of the large-scale structure, introduced at the linear level of the perturbation equations in General Relativity, and the suppression in structure formation caused by non-vanishing neutrino mass?
