Determining H 0 with the Latest H ii Galaxy Measurements

Abstract

We use the latest H ii galaxy measurements to determine the value of H 0 by adopting a combination of model-dependent and model-independent methods. By constraining five cosmological models, we find that the obtained values of H 0 are more consistent with the recent local measurement by Riess et al. at the 1 σ confidence level. For the first time, we implement the model-independent Gaussian processes using the H ii galaxy measurements, and confirm the correctness of H 0 values obtained by the model-dependent method at the 1 σ confidence level.
