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…
Euclid preparation. Constraining parameterised models of modifications of gravity with the spectroscopic and photometric primary probes
Euclid Collaboration, I. S. Albuquerque, N. Frusciante +285
The Euclid mission has the potential to understand the fundamental physical nature of late-time cosmic acceleration and, as such, of deviations from the standard cosmological model…
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…
