Cosmological simulations of scale-dependent primordial non-Gaussianity
Marco Baldi, Emanuele Fondi, Dionysios Karagiannis +9
We present the results of a set of cosmological N-body simulations with standard CDM cosmology but characterized by a scale-dependent primordial non-Gaussianity of the local ty…
