Neutrinos

In order to prepare a new mission, forecasts are a must. This work builds on a previously made programm called TotallySAF designed to produce forecasts for Euclid on a certain number of classic cosmological parameters, through Fisher matrixes. The novelty of this work resides in the addition of a new free cosmological parameter, the neutrino density, directly related to the neutrino mass....
