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…
The assembly bias of emission line galaxies
Esteban Jimenez, Nelson Padilla, Sergio Contreras +3
The next generation of spectroscopic surveys will target emission-line galaxies (ELGs) to produce constraints on cosmological parameters. We study the large scale structure traced…
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…
Dissecting and Modelling Galaxy Assembly Bias
Xiaoju Xu, Idit Zehavi, Sergio Contreras
Understanding the galaxy-halo connection is fundamental for contemporary models of galaxy clustering. The extent to which the haloes' assembly history and environment impact galaxy…
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…
