Galaxy cluster gas mass fraction versus redshift data and Hubble parameter versus redshift data are used to jointly constrain dark energy models. These constraints favor the Einstein cosmological constant limit of dark energy but do not strongly rule out slowly-evolving dark energy.

  1. Using SPTpol, Planck 2015, and non-CMB data to constrain tilted spatially-flat and untilted non-flat $\Lambda$CDM, XCDM, and $\phi$CDM dark energy inflation cosmologies

    astro-ph.CO 2019-08 conditional novelty 5.0 of 10

    Joint constraints from SPTpol, Planck 2015, and non-CMB data in six dark energy cosmologies find no strong data tension and continue to favor spatially closed universes over flat ones.

  2. Quasar X-ray and UV flux, baryon acoustic oscillation, and Hubble parameter measurement constraints on cosmological model parameters

    astro-ph.CO 2019-09 conditional novelty 4.0 of 10

    Quasar X-ray and UV flux data are weak but consistent with BAO and H(z) data, and the joint data mildly favor closed spatial geometry and dynamical dark energy over flat LambdaCDM.
