The cosmological dependence of halo and galaxy assembly bias

Sergio Contreras, Jonás Chaves-Montero, Matteo Zennaro +1

One of the main predictions of excursion set theory is that the clustering of dark matter haloes only depends on halo mass. However, it has been long established that the clusterin…

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…

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…

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…
