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 combines two different techniques: a rescaling algorithm that modifies the cosmology of gravity-only N-body simulations, and a baryonification algorithm which mimics the effects of astrophysical processes induced by baryons, such as star formation and AGN feedback. We show how this approach can accurately reproduce the… 
A hydrodynamical halo model for weak-lensing cross correlations
On the scale of galactic haloes, the distribution of matter in the cosmos is affected by energetic, non-gravitational processes, the so-called baryonic feedback. A lack of knowledge about the details
3 per cent-accurate predictions for the clustering of dark matter, haloes, and subhaloes, over a wide range of cosmologies and scales
Predicting the spatial distribution of objects as a function of cosmology is an essential ingredient for the exploitation of future galaxy surveys. In this paper we show that a specially-designed
Imprint of baryons and massive neutrinos on velocity statistics
We explore the impact of baryonic effects (namely stellar and AGN feedback) on the moments of pairwise velocity using the Illustris-TNG, EAGLE, cosmo-OWLS, and BAHAMAS suites of cosmological
The BACCO simulation project: exploiting the full power of large-scale structure for cosmology
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 cosmological
Joint galaxy–galaxy lensing and clustering constraints on galaxy formation
We compare predictions for galaxy-galaxy lensing profiles and clustering from the Henriques et al. (2015) public version of the Munich semi-analytical model of galaxy formation (SAM) and the
Cosmological parameter estimation via iterative emulation of likelihoods
This work proposes a new approach to parameter estimation based on an iterative Gaussian emulation of the target likelihood function, which requires a minimal number of likelihood evaluations and naturally accommodates for stochasticity in theoretical models.

We study the impact that uncertainties on assumed relations between galaxy bias parameters have on constraints of the local PNG $f_{\rm NL}$ parameter. We focus on the relation between the linear
Constraining the Baryonic Feedback with Cosmic Shear Using the DES Year-3 Small-Scale Measurements
The final round of the WTA Finals was played on Saturday with the top eight finishers securing a place in the quarter-finals for the first time since the tournament was revamped in 2009.
A Full $w$CDM Analysis of KiDS-1000 Weak Lensing Maps using Deep Learning
We present a full forward-modeled w CDM analysis of the KiDS-1000 weak lensing maps using graph-convolutional neural networks (GCNN). Utilizing the CosmoGrid , a novel massive simulation suite


Towards a realistic population of simulated galaxy groups and clusters
We present a new suite of large-volume cosmological hydrodynamical simulations called cosmo-OWLS. They form an extension to the OverWhelmingly Large Simulations (OWLS) project, and have been designed
The BAHAMAS project: Calibrated hydrodynamical simulations for large-scale structure cosmology
The evolution of the large-scale distribution of matter is sensitive to a variety of fundamental parameters that characterise the dark matter, dark energy, and other aspects of our cosmological
The impact of baryons on the matter power spectrum from the Horizon-AGN cosmological hydrodynamical simulation
Accurate cosmology from upcoming weak lensing surveys relies on knowledge of the total matter power spectrum at percent level at scales $k < 10$ $h$/Mpc, for which modelling the impact of baryonic
A new method to quantify the effects of baryons on the matter power spectrum
Future large-scale galaxy surveys have the potential to become leading probes for cosmology provided the influence of baryons on the total mass distribution is understood well enough. As
The clustering of baryonic matter. II: halo model and hydrodynamic simulations
We recently developed a generalization of the halo model in order to describe the spatial clustering properties of each mass component in the Universe, including hot gas and stars. In this work we

We use a suite of high-resolution N-body simulations and state-of-the-art perturbation theory to improve the code halofit, which predicts the nonlinear matter power spectrum. We restrict attention to
One simulation to fit them all - changing the background parameters of a cosmological N-body simulation
We demonstrate that the output of a cosmological N-body simulation can, to remarkable accuracy, be scaled to represent the growth of large-scale structure in a cosmology with parameters similar to
Baryons, neutrinos, feedback and weak gravitational lensing
The effect of baryonic feedback on the dark matter mass distribution is generally considered to be a nuisance to weak gravitational lensing. Measurements of cosmological parameters are affected as
The clustering of baryonic matter. I: a halo-model approach
In this paper I generalize the halo model for the clustering of dark matter in order to produce the power spectra of the two main baryonic matter components in the Universe: stars and hot gas. As a

Observational cosmology in the next decade will rely on probes of the distribution of matter in the redshift range between $0<z<3$ to elucidate the nature of dark matter and dark energy. In this
