Constraints on dark energy dynamics and spatial curvature from Hubble
  parameter and baryon acoustic oscillation data
  We use all available baryon acoustic oscillation distance measurements and
Hubble parameter data to constrain the cosmological constant $\Lambda$,
dynamical dark energy, and spatial curvature in simple cosmological models. We
find that the consensus spatially flat $\Lambda$CDM model provides a reasonable
fit to the data, but depending on the Hubble constant prior and cosmological
model, it can be a little more than 1$\sigma$ away from the best-fit model,
which can favor mild dark energy dynamics or non-flat spatial hypersurfaces.
