The BACCO Simulation Project: A baryonification emulator with Neural Networks
Giovanni Aricò, Raul E. Angulo, Sergio Contreras +3
We present a neural-network emulator for baryonic effects in the non-linear matter power spectrum. We calibrate this emulator using more than 50,000 measurements in a 15-dimensiona…
Simultaneous modelling of matter power spectrum and bispectrum in the presence of baryons
Giovanni Aricò, Raul E. Angulo, Carlos Hernández-Monteagudo +2
We demonstrate that baryonification algorithms, which displace particles in gravity-only simulations according to physically-motivated prescriptions, can simultaneously capture the…
Modelling the large scale structure of the Universe as a function of cosmology and baryonic physics
Giovanni Aricò, Raul E. Angulo, Carlos Hernández-Monteagudo +4
We present and test a framework that models the three-dimensional distribution of mass in the Universe as a function of cosmological and astrophysical parameters. Our approach comb…
How to add massive neutrinos to your CDM simulation -- extending cosmology rescaling algorithms
Matteo Zennaro, Raúl E. Angulo, Giovanni Aricò +2
Providing accurate predictions for the spatial distribution of matter and luminous tracers in the presence of massive neutrinos is an important task, given the imminent arrival of…
