  • In this paper we use all available baryon acoustic oscillation and Hubble parameter data to constrain six dark energy cosmological models, both spatially flat and non-flat. These data mildly favor (at 1.3-1.4$\sigma$) closed spatial hypersurfaces in the dynamical dark energy models, and favor dark energy dynamics (at $>1$-2$\sigma$, depending on the model) over a cosmological constant $\Lambda$. They also favor, at 2.2$\sigma$ to $3.5\sigma$, depending on the model, a lower Hubble constant than… CONTINUE READING
