dc.description.abstract | We use 28 measurements of the Hubble parameter, H(z), at intermediate redshifts 0.07 <= z <= 2.3 to determine the present-day Hubble constant H-0 in four cosmological models. We measure H-0 = 68.3(-2.6)(+2.7), 68.4(-3.3)(+2.9), 65.0(-6.6)(+6.5) and 67.9(-2.4)(+2.4) km s(-1) Mpc(-1) (1 sigma errors) in the Lambda CDM (spatially flat and non-flat), omega CDM, and phi CDM models, respectively. These measured H-0 values are more consistent with the lower values determined from recent data on the cosmic microwave background and baryon acoustic oscillations, as well as with the value found from a median statistical analysis of Huchra's compilation of H-0 measurements, but include the higher local measurements of H-0 within the 2 sigma confidence limits. | |
