Primordial non-Gaussianity and non-Gaussian Covariance

  title={Primordial non-Gaussianity and non-Gaussian Covariance},
  author={Thomas Floss and Matteo Biagetti and Pieter Daniel Meerburg},
In the pursuit of primordial non-Gaussianities, we hope to access smaller scales across larger comoving volumes. At low redshift, the search for primordial non-Gaussianities is hindered by gravitational collapse, to which we often associate a scale kNL. Beyond these scales, it will be hard to reconstruct the modes sensitive to the primordial distribution. When forecasting future constraints on the amplitude of primordial non-Gaussianity, fNL, off-diagonal components are usually neglected in the…
