Abstract
The goal of cosmology is to characterize the Universe’s contents, distributions and motion. Why the Universe’s expansion rate is accelerating can be explained by Λ, a added factor to the Einstein field formula. The ΛCDM model is the most simple and widely used model, but it has some theatrical issues. Therefore, cosmologists are searching for its alternative. The barotropic fluid model, the canonical scalar field model and the non-canonical scalar field model are among them. In this study We provide a comparative examining dark energy models using Bayesian model selection. To do this, we utilize observational data of supernova type Ia, Hubble parameter and Baryon acoustic oscillation measurements.
