MG-NECOLA: A Field-Level Emulator for Gravity and Massive Neutrino Cosmologies
J. Bayron Orjuela-Quintana, Mauricio Reyes, Elena Giusarma +3
Accurate modeling of non-linear gravitational dynamics is essential for constraining extensions to the standard cosmological model using large-scale structure observations. While h…
Field-Level Inference of Primordial Non-Gaussianity with the Quijote Simulation Suite
Adam Andrews, Jens Jasche, Guilhem Lavaux +10
Local primordial non-Gaussianity, parameterised as , will be stringently constrained using state-of-the-art methods applied to next-generation galaxy redshi…
: Accurate non-Gaussian initial conditions with arbitrary bispectrum for N-body simulations
Emanuele Fondi, Licia Verde, Marco Baldi +3
Primordial non-Gaussianity is predicted by various inflationary models, and N-body simulations are a crucial tool for studying its imprints on large-scale structure. In this work,…
A revisited Correction to the Halo Mass Function for local-type Primordial non-Gaussianity
Luca Fiorino, Sofia Contarini, Federico Marulli +4
We investigate the effect of primordial non-Gaussianities on halo number counts using N-body simulations with different values of . We show how current theore…
Probing massive neutrinos and modified gravity with redshift-space morphologies and anisotropies of large-scale structure
Wei Liu, Liang Wu, Francisco Villaescusa-Navarro +3
Strong degeneracy exists between some modified gravity (MG) models and massive neutrinos because the enhanced structure growth produced by modified gravity can be suppressed due to…
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…
