Cosmology and Neutrinos, of fixed and variable mass
Thanks to recent data about the Cosmic Microwave Background (CMB), Large Scale Structures (LSS) and also Type Ia Supernovæ (SNe), cosmology has become the most sensitive probe of some neutrino properties and a very sensitive probe of others, including non standard ones [1, 2, 3]. On the issue of v masses, cosmological observations play the dominant role nowadays: oscillation experiments test squared-mass differences, and other means of probing the absolute v mass are less sensitive. On the other hand, cosmology may have an even deeper connection with neutrinos, being at the very origin of their mass, according to the proposal of Mass Varying Neutrinos (MaVaNs) .
