Exploring hints for dark energy density evolution in light of recent data
Considering a quadratic parameterization of the dark energy density, we explore signatures of evolution using data from gas mass fraction in clusters, type Ia supernova, BAO and CMB. We find – excluding CMB data – a preference for an evolution of ρde(z) towards smaller values as the redshift increas...
