Non-Gaussianities may impact neutrino constraints
This paper proposes an extension to the standard cosmological model called Super-LambdaCDM, which includes extra parameters to model primordial non-Gaussianities. The authors find hints these new parameters deviate from zero, indicating non-Gaussianities. They show this impacts neutrino constraints, relaxing limits on neutrino mass by a factor of two. Locking the new parameters to zero may bias neutrino constraints.
