Gravitational Slip in the Parameterized Post-Newtonian Cosmology
Theodore Anton, Timothy Clifton, Daniel B. Thomas
A key signature of general relativity is that the two scalar potentials and , when expressed in the longitudinal gauge, are equal in the absence of fluids with anisotropic…
A New Paradigm for Testing Gravity: Theory-Independent Constraints Using Data From All Astrophysical and Cosmological Scales
Daniel B Thomas, Theodore Anton, Timothy Clifton
Testing General Relativity (GR) is a key science goal of much of modern physics, and usually results in constraints that are either theory or context specific. We present an holist…
Assessing cosmological evidence for non-minimal coupling
William J. Wolf, Carlos GarcÃa-GarcÃa, Theodore Anton +1
The recent observational evidence of deviations from the -Cold Dark Matter (CDM) model points towards the presence of evolving dark energy. The simplest possibility consist…
Constraining Post-Newtonian Parameters with the Cosmic Microwave Background
Daniel B. Thomas, Theodore Anton, Timothy Clifton +1
The Parameterised Post-Newtonian (PPN) approach is the default framework for performing precision tests of gravity in nearby astrophysical systems. In recent works we have extended…
