Observational Data and Cosmological Models

Abstract

In this work, we confront ten cosmological models with observational data. The possible interaction between dark energy and dust matter is allowed in some of these models. Also, we consider the possibility of (effective) equation-of-state parameter (EoS) crossing -1. We find that the best models have an oscillating feature for both and EoS, with the EoS crossing -1 around redshift .
