Observational Tests for Distinguishing Classes of Cosmological Models
Asta Heinesen, Timothy Clifton
We investigate observational tests that can be used to distinguish between broad classes of cosmological models. This is achieved using curvature-consistency tests of the Friedmann…
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 s…
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…
A Radical Solution to the Hubble Tension Problem
Timothy Clifton, Neil Hyatt
The Hubble tension has proven to be stubbornly persistent, despite widespread efforts to relax it. As a possible resolution of this problem we propose a radical alternative to the…
