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…
Non-Gaussianity in multi-sound-speed disformally coupled inflation
Carsten van de Bruck, Tomi Koivisto, Chris Longden
Most, if not all, scalar-tensor theories are equivalent to General Relativity with a disformally coupled matter sector. In extra-dimensional theories such a coupling can be underst…
Reheating and preheating in the simplest extension of Starobinsky inflation
C. van de Bruck, P. Dunsby, L. E. Paduraru
The epochs of reheating and preheating are studied in a simple extension of the Starobinsky inflationary model, which consists of an --correction to the Einstein--Hilbert acti…
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…
Running of the Running and Entropy Perturbations During Inflation
Carsten van de Bruck, Chris Longden
In single field slow-roll inflation, one expects that the spectral index is first order in slow-roll parameters. Similarly, its running and the runni…
Generalized dark energy interactions with multiple fluids
Carsten van de Bruck, Jurgen Mifsud, José P. Mimoso +1
In the search for an explanation for the current acceleration of the Universe, scalar fields are the most simple and useful tools to build models of dark energy. This field, howeve…
