Testing coupled dark energy models with their cosmological background evolution
Carsten van de Bruck, Jurgen Mifsud, Jack Morrice
We consider a cosmology in which dark matter and a quintessence scalar field responsible for the acceleration of the Universe are allowed to interact. Allowing for both conformal a…
Vacuum Cherenkov radiation and bremsstrahlung from disformal couplings
Carsten van de Bruck, Clare Burrage, Jack Morrice
The simplest way to modify gravity is to extend the gravitational sector to include an additional scalar degree of freedom. The most general metric that can be built in such a theo…
Disformal couplings and the dark sector of the universe
C. van de Bruck, J. Morrice
Interactions between dark matter and dark energy, allowing both conformal and and disformal couplings, are studied in detail. We discuss the background evolution, anisotropies in t…
Constraints on Disformal Couplings from the Properties of the Cosmic Microwave Background Radiation
Carsten van de Bruck, Jack Morrice, Susan Vu
Certain modified gravity theories predict the existence of an additional, non-conformally coupled scalar field. A disformal coupling of the field to the Cosmic Microwave Background…
