The matter density PDF for modified gravity and dark energy with Large Deviations Theory
TL;DR: In this paper , the authors present an analytical description of the probability distribution function (PDF) of the smoothed three-dimensional matter density field for modified gravity and dark energy, which is applicable to general extensions of the standard Lambda$CDM cosmology.
Journal ArticleDOI
OUP accepted manuscript
TL;DR: In this article , a simulated likelihood analysis of the galaxy clustering and weak lensing data from the Roman Space Telescope High Latitude Survey combined with CMB lensing from the Simons Observatory is undertaken, marginalizing over important astrophysical effects and calibration uncertainties.

Towards an accurate model of the redshift-space clustering of haloes in the quasi-linear regime
TL;DR: In this article, a detailed study of halo clustering and velocity statistics in 67.5 ǫh−3 Gpc3 of N-body simulations is presented, which reveals a complex dependence of redshift-space clustering on halo bias.
Journal ArticleDOI
N-body simulations for f(R) gravity using a self-adaptive particle-mesh code.
TL;DR: In this article, the authors performed high-resolution N-body simulations for f(R) gravity based on a self-adaptive particlemesh code MLAPM, where the Chameleon mechanism that recovers General Relativity on small scales is fully taken into account by self-consistently solving the non-linear equation for the scalar field.
Journal ArticleDOI
Convolution Lagrangian perturbation theory for biased tracers
TL;DR: In this paper, a non-perturbative resummation of Lagrangian perturbation theory is presented, which allows accurate predictions of the real and redshift-space correlation funct ions of the mass field and dark matter halos.
Journal ArticleDOI
Power Spectrum Correlations Induced by Nonlinear Clustering
TL;DR: In this article, the power-spectrum covariance matrix in nonlinear perturbation theory (weakly nonlinear regime), in the hierarchical model, and from numerical simulations in real and redshift space is calculated for galaxy and weak-lensing surveys.

Towards an accurate model of the redshift space clustering of halos in the quasilinear regime
Beth Reid,Martin White +1 more
TL;DR: In this paper, the authors use perturbation theory to predict the real-space pairwise halo velocity statistics and show that their model is accurate at the 2 per cent level only on scales s > 40 Mpc/h.
