Abstract
While the canonical cosmological model to explain the recent acceleration of the universe relies on a cosmological constant and most dynamical dark energy model alternatives are based on scalar fields, further alternatives are possible. One of these involves vector fields: under certain conditions, they can lead to accelerating universes while preserving homogeneity and isotropy. In this work we report on updated observational constraints on three different but related models, previously proposed in the literature.
