Modelling the emergence of cosmic anisotropy from non-linear structures
Theodore Anton, Timothy Clifton
Astronomical observations suggest that the Universe may be anisotropic on the largest scales. In order to model this situation, we develop a new approach to cosmology that allows f…
Scale-Dependent Gravitational Couplings in Parameterised Post-Newtonian Cosmology
Daniel B. Thomas, Timothy Clifton, Theodore Anton
Parameterised Post-Newtonian Cosmology (PPNC) is a theory-agnostic framework for testing gravity in cosmology, which connects gravitational physics on small and large scales in the…
The 4D Einstein-Gauss-Bonnet Theory of Gravity: A Review
Pedro G. S. Fernandes, Pedro Carrilho, Timothy Clifton +1
We review the topic of 4D Einstein-Gauss-Bonnet gravity, which has been the subject of considerable interest over the past two years. Our review begins with a general introduction…
The momentum constraint equation in Parameterised Post-Newtonian Cosmology
Theodore Anton, Timothy Clifton
We derive a theory-independent version of the momentum constraint equation for use in cosmology, as a part of the Parameterised Post-Newtonian Cosmology (PPNC) framework. Our equat…
Black Holes in the Scalar-Tensor Formulation of 4D Einstein-Gauss-Bonnet Gravity: Uniqueness of Solutions, and a New Candidate for Dark Matter
Pedro G. S. Fernandes, Pedro Carrilho, Timothy Clifton +1
In this work we study static black holes in the regularized 4D Einstein-Gauss-Bonnet theory of gravity; a shift-symmetric scalar-tensor theory that belongs to the Horndeski class.…
Multi-Scale Perturbation Theory II: Solutions and Leading-Order Bispectrum in the CDM Universe
Christopher S. Gallagher, Timothy Clifton, Chris Clarkson
Two-parameter perturbation theory (2PPT) is a framework designed to include the relativistic gravitational effects of small-scale nonlinear structures on the large-scale properties…
