Cosmological-model-independent Determination of Hubble Constant from Fast Radio Bursts and Hubble Parameter Measurements

[摘要] We establish a cosmological-model-independent method to determine the Hubble constantH ₀ from the localized fast radio bursts (FRBs) and the Hubble parameter measurements from cosmic chronometers and obtain a first such determinationH ₀ = 71 ± 3 km s⁻¹ Mpc⁻¹, with an uncertainty of 4%, from the eighteen localized FRBs and nineteen Hubble parameter measurements in the redshift range 0 0 can be decreased to the level of that from the nearby SNe Ia when mock data from 500 localized FRBs with 50 Hubble parameter measurements in the redshift range of 0 0 in the very near future, which will help us to figure out the possible origin of the Hubble constant disagreement.
