A flexible subhalo abundance matching model for galaxy clustering in redshift space
Sergio Contreras, Raul Angulo, Matteo Zennaro
We develop an extension of subhalo abundance matching (SHAM) capable of accurately reproducing the real and redshift-space clustering of galaxies in a state-of-the-art hydrodynamic…
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…
A flexible modelling of galaxy assembly bias
Sergio Contreras, Raul Angulo, Matteo Zennaro
We use the {\sc Illustris TNG300} magneto-hydrodynamic simulation, the {\sc SAGE} semi-analytical model, and the subhalo abundance matching technique (SHAM) to examine the diversit…
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…
