Estimates of cluster masses in screened modified gravity
Max Gronke, A. Hammami, David F. Mota +1
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 nove…
Probing modified gravity via the mass-temperature relation of galaxy clusters
Amir Hammami, David F. Mota
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…
Cosmological simulations with hydrodynamics of screened scalar-tensor gravity with non-universal coupling
Amir Hammami, David F. Mota
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…
Hydrodynamic Effects in the Symmetron and -gravity Models
Amir Hammami, Claudio Llinares, David F. Mota +1
In this paper we present the first results from implementing two scalar-tensor modified gravity theories, the symmetron and the Hu-Sawicki -gravity model, into a hydrodynamic…
Gauge Issues in Extended Gravity and f(R) Cosmology
Iain A. Brown, Amir Hammami
We consider issues related to the conformal mapping between the Einstein and Jordan frames in f(R) cosmology. We consider the impact of the conformal transformation on the gauge of…
