Query: Quasar X-ray and UV flux, baryon acoustic oscillation, and Hubble
  parameter measurement constraints on cosmological model parameters   We use the Risaliti & Lusso (2015) compilation of 808 X-ray and UV flux
measurements of quasars (QSOs) in the redshift range $0.061 \leq z \leq 6.28$,
alone and in conjuction with baryon acoustic oscillation (BAO) and Hubble
parameter [$H(z)$] measurements, to constrain cosmological parameters in six
cosmological models. The QSO data constraints are significantly weaker than,
but consistent with, those from the $H(z)$ + BAO data. A joint analysis of the
QSO + $H(z)$ + BAO data is consistent with the current standard model,
spatially-flat $\Lambda$CDM, but mildly favors closed spatial hypersurfaces and
dynamical dark energy.
