Constraining Neutrino Cosmologies with Nonlinear Reconstruction

Constraining Neutrino Cosmologies with Nonlinear Reconstruction

Nonlinear gravitational evolution induces strong nonlinearities in the observed cosmological density fields, leading to positive off-diagonal correlations in the power spectrum covariance. This has caused the information saturation in the power spectrum, e.g., the neutrino mass constraints from the...
