Evolution of sub-horizon cold dark matter perturbations

Christian G. Boehmer, Gabriela Caldera-Cabral

We investigate the evolution of sub-horizon cold dark matter perturbation in the dark energy dominated era of the Universe. By generalising the Meszaros equation to be valid for an…

Theoretical Priors On Modified Growth Parametrisations

Yong-Seon Song, Lukas Hollenstein, Gabriela Caldera-Cabral +1

Next generation surveys will observe the large-scale structure of the Universe with unprecedented accuracy. This will enable us to test the relationships between matter over-densit…

Quintessence with quadratic coupling to dark matter

Christian G. Boehmer, Gabriela Caldera-Cabral, Nyein Chan +2

We introduce a new form of coupling between dark energy and dark matter that is quadratic in their energy densities. Then we investigate the background dynamics when dark energy is…

The Growth of Structure in Interacting Dark Energy Models

Gabriela Caldera-Cabral, Roy Maartens, Bjoern Malte Schaefer

If dark energy interacts with dark matter, there is a change in the background evolution of the universe, since the dark matter density no longer evolves as a^{-3}. In addition, th…

Dynamics of interacting dark energy

Gabriela Caldera-Cabral, Roy Maartens, L. Arturo Urena-Lopez

Dark energy and dark matter are only indirectly measured via their gravitational effects. It is possible that there is an exchange of energy within the dark sector, and this offers…

Constraints on the decay of dark matter to dark energy from weak lensing bispectrum tomography

Bjoern Malte Schaefer, Gabriela Alejandra Caldera-Cabral, Roy Maartens

We consider a phenomenological model for a coupling between the dark matter and dark energy fluids and investigate the sensitivity of a weak lensing measurement for constraining th…
