Beyond CDM: Problems, solutions, and the road ahead
Philip Bull, Yashar Akrami, Julian Adamek +37
Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…
Weak lensing of large scale structure in the presence of screening
Nicolas Tessore, Hans A. Winther, R. Benton Metcalf +2
A number of alternatives to general relativity exhibit gravitational screening in the non-linear regime of structure formation. We describe a set of algorithms that can produce wea…
Modified Gravity N-body Code Comparison Project
Hans A. Winther, Fabian Schmidt, Alexandre Barreira +12
Self-consistent -body simulations of modified gravity models are a key ingredient to obtain rigorous constraints on deviations from General Relativity using large-scale st…
The Vainshtein mechanism beyond the quasi-static approximation
Hans A. Winther, Pedro G. Ferreira
Theories of modified gravity, in both the linear and fully non-linear regime, are often studied under the assumption that the evolution of the new (often scalar) degree of freedom…
Universal predictions of screened modified gravity on cluster scales
Max Gronke, David F. Mota, Hans A. Winther
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 as…
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…
Testing General Relativity with Present and Future Astrophysical Observations
Emanuele Berti, Enrico Barausse, Vitor Cardoso +50
One century after its formulation, Einstein's general relativity has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests pr…
