Emergent Cosmological Expansion in Scalar-Tensor Theories of Gravity
Chad Briddon, Timothy Clifton, Pierre Fleury
We consider the emergence of large-scale cosmological expansion in scalar-tensor theories of gravity. This is achieved by modelling sub-horizon regions of space-time as weak-field…
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…
Hubble Diagrams in Statistically Homogeneous, Anisotropic Universes
Theodore Anton, Timothy Clifton
We consider the form of Hubble diagrams that would be constructed by observers in universes that are homogeneous but anisotropic, when averaged over suitably large length-scales. T…
