Cosmology of vector dark energy models

Awarded: NOK 33,999

The aim of the visit will be to study several observational consequences of dark energy models based on vector fields. In particular, we shall consider the recently proposed model in which such a vector field is nothing but the electromagnetic field. We s hall study the evolution of the cosmological perturbations for this model and the implications for the anisotropies of the CMB and structure formation. We shall also study the possibility that these vector fields could drive an inflationary era and their consequences for CMB anisotropies and, in particular, whether these models could account for the observed anomalies of the CMB such as the axis of evil or the lack of power for low multipoles.
