Ambiguous tests of general relativity on cosmological scales
Zuntz, J.; Baker, T.; Ferreira, P. G.; Skordis, C. (2012)There are a number of approaches to testing General Relativity (GR) on linear scales using parameterized frameworks for modifying cosmological perturbation theory. It is sometimes assumed that the details of any given ...

(2013)Euclid is a European Space Agency medium-class mission selected for launch in 2019 within the Cosmic Vision 2015 - 2025 program. The main goal of Euclid is to understand the origin of the accelerated expansion of the ...

A fast route to modified gravitational growth
Baker, T.; Ferreira, P.; Skordis, C. (2014)The growth rate of the large-scale structure of the Universe has been advocated as the observable par excellence for testing gravity on cosmological scales. By considering linear-order deviations from general relativity, ...

Linking tests of gravity on all scales: From the strong-field regime to cosmology
Baker, T.; Psaltis, D.; Skordis, C. (2015)The current effort to test general relativity (GR) employs multiple disparate formalisms for different observables, obscuring the relations between laboratory, astrophysical, and cosmological constraints. To remedy this ...

The parameterized post-Friedmann framework for theories of modified gravity: Concepts, formalism, and examples
Baker, T.; Ferreira, P. G.; Skordis, C. (2013)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 post-Friedmann framework (PPF), ...

Testing general relativity with cosmology: a synopsis of the parametrized post-Friedmann approach
Ferreira, P. G.; Baker, T.; Skordis, C. (2014)More than half a century after the Chapel Hill meeting of 1957, the landscape of general relativity has been transformed. In relativistic cosmology we are entering an era in which we can seriously consider testing some of ...
