The constraining power of the Marked Power Spectrum: an analytical study
Marco Marinucci, Gabriel Jung, Michele Liguori +8
The marked power spectrum - a two-point correlation function of a transformed density field - has emerged as a promising tool for extracting cosmological information from the large…
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 typ…
Constraining Primordial Non-Gaussianity from Large Scale Structure with the Wavelet Scattering Transform
Matteo Peron, Gabriel Jung, Michele Liguori +1
We investigate the Wavelet Scattering Transform (WST) as a tool for the study of Primordial non-Gaussianity (PNG) in Large Scale Structure (LSS), and compare its performance with t…
Quijote-PNG: Optimizing the summary statistics to measure Primordial non-Gaussianity
Gabriel Jung, Andrea Ravenni, Michele Liguori +4
We apply a suite of different estimators to the Quijote-PNG halo catalogues to find the best approach to constrain Primordial non-Gaussianity (PNG) at non-linear cosmological scale…
