 "The GRB rate, GRB hosts, GRB/SN spatial distribution: a unifying proposal to address these three puzzles"
+"Neutrino Cosmology"
+The new full sky galaxy surveys (EUCLID/SKA) will provide an unprecedented measurement of the non-linear modes of the power spectrum of galaxies and the underlying dark matter. This will open the possibility to explore neutrino properties. In particular a detection of its mass is secure and also the possibility of detecting the hierarchy, thus helping elucidate the origin of mass in neutrinos. In this talk I will show how this can be done and will present recent results on limits on the hierarchy, total mass of neutrinos and their number opt species by using astronomical observations.
