The promising future of a robust cosmological neutrino mass measurement
  We forecast the sensitivity of thirty-five different combinations of future
Cosmic Microwave Background and Large Scale Structure data sets to cosmological
parameters and to the total neutrino mass. We work under conservative
assumptions accounting for uncertainties in the modelling of systematics. In
particular, for galaxy redshift surveys, we remove the information coming from
non-linear scales. We use Bayesian parameter extraction from mock likelihoods
to avoid Fisher matrix uncertainties. Our grid of results allows for a direct
comparison between the sensitivity of different data sets. We find that future
surveys will measure the neutrino mass with high significance and will not be
substantially affected by potential parameter degeneracies between neutrino
masses, the density of relativistic relics, and a possible time-varying
equation of state of Dark Energy.
