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

Abstract (from CDS):

We use updated Hubble parameter and baryon acoustic oscillation data, as well as other lower redshift Type Ia supernova, Mg II reverberation-measured quasar, quasar angular size, H II starburst galaxy, and Amati-correlated gamma-ray burst data, to jointly constrain cosmological parameters in six cosmological models. The joint analysis provides model-independent determinations of the Hubble constant, H0 = 69.7 ±1.2 km s–1 Mpc–1 and the current non-relativistic matter density parameter, Ωm0 = 0.295 ± 0.017. These error bars are factors of 2.2 and 2.3 larger than the corresponding error bars in the flat ΛCDM model from Planck TT,TE,EE+lowE + lensing cosmic microwave background anisotropy data. Based on the deviance information criterion (DIC), the flat ΛCDM model is most favoured but mild dark energy dynamics and a little spatial curvature are not ruled out.
