We study the growth of structures in modified gravity models where the Poisson equation and the relationship between the two Newtonian potentials are modified by explicit functions of space and time. This parameterisation applies to the $f(R)$ models and more generally to screened modified gravity models. We investigate the linear and weakly nonlinear regimes using the "standard" perturbative approach and a resummation technique, while we use the spherical dynamics to go beyond low-order… 

Impact on the power spectrum of Screening in Modified Gravity Scenarios

We study the effects of screened modified gravity of the $f(R)$, dilaton and symmetron types on structure formation, from the quasi-linear to the non-linear regime, using semi-analytical methods. For

Modelling the non-linear bispectrum in modified gravity

Future large-scale structure surveys will measure three-point correlations with high statistical significance. This will offer significant improvements on our understanding of gravity, provided we

Modelling the matter bispectrum at small scales in modified gravity

Future large-scale structure surveys will measure three-point statistics with high statistical significance. This will offer significant improvements on our understanding of gravity, provided we can

The evolution of the large-scale structure of the universe: beyond the linear regime

These lecture notes introduce analytical tools, methods and results describing the growth of cosmological structure beyond the linear regime. The presentation is focused on the single flow regime of

Lyman-α power spectrum as a probe of modified gravity

We investigate the impact of modified-gravity models on the Lyman-α power spectrum. Building a simple analytical modeling, based on a truncated Zeldovich approximation, we estimate the intergalactic

Visualization of cosmological density fluctuations with phase space analysis: case study: Brans–Dicke theory

Cosmological perturbation theory is a powerful tool to understanding the large-scale structure of the Universe. However, the set of field equations describes the general linear perturbations for the

Impact of a warm dark matter late-time velocity dispersion on large-scale structures

We investigate whether the late-time (at $z\leq 100$) velocity dispersion expected in Warm Dark Matter scenarios could have some effect on the cosmic web (i.e., outside of virialized halos). We

Cluster abundance in chameleon f(R) gravity I: toward an accurate halo mass function prediction

We refine the mass and environment dependent spherical collapse model of chameleon f(R) gravity by calibrating a phenomenological correction inspired by the parameterized post-Friedmann framework

The Parameterized Post-Friedmann Framework for Theories of Modified Gravity: Concepts, Formalism and Examples.

A unified framework for theories of modified gravity will be an essential tool for interpreting the forthcoming deluge of cosmological data. We present such a formalism, the Parameterized

Matter power spectrum from a Lagrangian-space regularization of perturbation theory

We present a new approach to computing the matter density power spectrum, from large linear scales to small highly nonlinear scales. Instead of explicitly computing a partial series of high-order

Quantum Field Theory and Critical Phenomena

Introduced as a quantum extension of Maxwell's classical theory, quantum electrodynamic (QED) has been the first example of a quantum field theory (QFT). Eventually, QFT has become the framework for

Large-scale structure in the Universe

A variety of observations constrain models of the origin of large-scale cosmic structures. Enough observational data have accumulated to constrain (and perhaps determine) the power spectrum of
