We use cosmological hydrodynamical simulations to study the effect of screened modified gravity models on the mass estimates of galaxy clusters. In particular, we focus on two novel aspects: (i) we study modified gravity models in which baryons and dark matter are coupled with different strengths to the scalar field, and; (ii) we put the simulation results into the greater context of a general screened-modified gravity parametrization. We have compared the mass of clusters inferred via lensing… Expand

Probing modified gravity via the mass-temperature relation of galaxy clusters
We propose that the mass-temperature relation of galaxy clusters is a prime candidate for testing gravity theories beyond Einstein's general relativity, for modified gravity models with universalExpand
A general framework to test gravity using galaxy clusters I : modelling the dynamical mass of haloes in f(R) gravity.

Stellar kinematics from the symmetron fifth force in the Milky Way disk
It has been shown that the presence of non-minimally coupled scalar fields giving rise to a fifth force can noticeably alter dynamics on galactic scales. Such a fifth force must be screened in theExpand

Cosmological simulations with hydrodynamics of screened scalar-tensor gravity with non-universal coupling
In this paper we study the effects of letting the dark matter and the gas in the Universe couple to the scalar field of the symmetron model, a modified gravity theory, with varying coupling strength.Expand
Cluster density profiles as a test of modified gravity

Modified gravity models require a screening mechanism to be able to evade the stringent constraints from local gravity experiments and, at the same time, give rise to observable astrophysical andExpand
