Chameleon fields may modify gravity on cluster scales while recovering general relativity
locally. This article reviews signatures of chameleon modifications in the nonlinear …

We forecast the main cosmological parameter constraints achievable with the CORE space
mission which is dedicated to mapping the polarisation of the Cosmic Microwave …

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 …

We forecast the main cosmological parameter constraints achievable with the CORE space
mission which is dedicated to mapping the polarisation of the Cosmic Microwave …

The recent measurements of cosmic microwave background (CMB) temperature and
polarization anisotropies made by the Planck satellite have provided impressive …

In order to explain cosmic acceleration without invoking``dark''physics, we consider f (R)
modified gravity models, which replace the standard Einstein-Hilbert action in General …

We use measurements from the Planck satellite mission and galaxy redshift surveys over the
last decade to test three of the basic assumptions of the standard model of cosmology …

We analyse modelling techniques for the large-scale structure formed in scalar-tensor
theories of constant Brans-Dicke parameter which match the concordance model …

The integrated Sachs-Wolfe (ISW) effect predicts additional anisotropies in the cosmic
microwave background (CMB) due to time variation of the gravitational potential when the …

We constrain f (R) and chameleon-type modified gravity in the framework of the Berstchinger-
Zukin parametrization using the recently released Planck data, including both the cosmic …
