Quinstant Dark Energy Predictions for Structure Formation
arXiv:0906.3713 · doi:10.1007/s10509-009-0062-2
Abstract
We explore the predictions of a class of dark energy models, quinstant dark energy, concerning the structure formation in the Universe, both in the linear and non-linear regimes. Quinstant dark energy is considered to be formed by quintessence and a negative cosmological constant. We conclude that these models give good predictions for structure formation in the linear regime, but fail to do so in the non-linear one, for redshifts larger than one.
