Web-Halo Model (WHM): Accurate non-linear matter power spectrum predictions without free parameters
Samuel Brieden, Florian Beutler, Marcos Pellejero-Ibañez
We present a parameter-free variant of the halo model that significantly improves the precision of matter clustering predictions, particularly in the challenging 1-halo to 2-halo t…
Covariance matrices for variance-suppressed simulations
Tony Zhang, Chia-Hsun Chuang, Risa H. Wechsler +9
Cosmological -body simulations provide numerical predictions of the structure of the Universe against which to compare data from ongoing and future surveys, but the growing volu…
Priors on Lagrangian bias parameters from galaxy formation modelling
Matteo Zennaro, Raul E. Angulo, Sergio Contreras +2
We study the relations among the parameters of the hybrid Lagrangian bias expansion model, fitting biased auto and cross power spectra up to $k_{\rm max} = 0.7 \, h \, \mathrm{Mpc}…
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…
The BACCO Simulation Project: Exploiting the full power of large-scale structure for cosmology
Raul E. Angulo, Matteo Zennaro, Sergio Contreras +3
We present the BACCO project, a simulation framework specially designed to provide highly-accurate predictions for the distribution of mass, galaxies, and gas as a function of cosm…
Cosmological parameter estimation via iterative emulation of likelihoods
Marcos Pellejero-Ibañez, Raul E. Angulo, Giovanni Aricó +3
The interpretation of cosmological observables requires the use of increasingly sophisticated theoretical models. Since these models are becoming computationally very expensive and…
