Quijote-png: Simulations of primordial non-gaussianity and the information content of the matter field power spectrum and bispectrum
Coulton, William R; Villaescusa-Navarro, Francisco; Karagiannis, Dionysios (IOP Publishing, 2023)Primordial non-Gaussianity (PNG) is one of the most powerful probes of the early universe, and measurements of the large-scale structure of the universe have the potential to transform our understanding of this area. ... -
Quijote-png: The information content of the halo power spectrum and bispectrum
Coulton, William R; Villaescusa-Navarro, Francisco; Karagiannis, Dionysios (IOP Publishing, 2023)We investigate how much can be learnt about four types of primordial non-Gaussianity (PNG) from small-scale measurements of the halo field. Using the QUIJOTE-PNG simulations, we quantify the information content accessible ...
