Baryon acoustic oscillation, Hubble parameter, and angular size measurement constraints on the Hubble constant, dark energy dynamics, and spatial curvature

In this paper, we use all available baryon acoustic oscillation, Hubble parameter, and quasar angular size data to constrain six dark energy cosmological models, both spatially flat and non flat, Depending on the model and data combination considered, these data mildly favour closed spatial hypersurfaces (by as much as 1.7 sigma) and dark energy dynamics (up to a little over 2 sigma) over a cosmological constant Lambda. The data also favour, at 1,8 sigma to 3,4 sigma, depending on the model and data combination, a lower Hubble constant than what is measured from the local expansion rate.
