Using lower-redshift, non-CMB, data to constrain the Hubble constant and other cosmological parameters

We use updated Hubble parameter and baryon acoustic oscillation data, as well other lower-redshift Type Ia supernova, Mg II reverberation-measured quasar, quasar angular size, H starburst galaxy, Amati-correlated gamma-ray burst to jointly constrain cosmological parameters in six models. The joint analysis provides model-independent determinations of the constant, $H_0=69.7\pm1.2$ $\rm{km \ s^{-1} Mpc^{-1}}$, current non-relativistic matter density parameter, $\Omega_{m0}=0.295\pm0.017$. These error bars are factors 2.2 2.3 larger than corresponding flat $\Lambda$CDM model from Planck TT,TE,EE+lowE+lensing cosmic microwave background anisotropy data. Based on deviance information criterion (DIC), is most favored but mild dark energy dynamics a little spatial curvature not ruled out.
