| There is a discrepancy between the Hubble constant measured in the early universe and the late universe,which leads to the Hubble tension.It is 5 σ disagreement between the Hubble constant H0=67.4±0.5/km s-1 Mpc-1 obtained by Planck collaboration using the temperature anisotropy of cosmic microwave background in the context of the ACDM model,and the Hubble constant H0=73.30±1.04/km s-1 Mpc-1 obtained from the model-independent analysis of the data of the luminosity-distance relation of Type Ⅰa supernovae calibrated by Cepheids by SH0ES team.In order to eliminate the discrepancy,many researchers have used a variety of methods to estimate the Hubble constant and obtained different results.Some researchers have put forward new theoretical schemes to try to reconcile this contradiction,but they have not achieved the expected results.In this paper,the Hubble constant is constrained by fast radio bursts(FRB s).FRB s are a kind of bright transients on the extragalactic distance scale.It carries information from the depths of the universe and can be used as a probe to research the universe.Using the dispersion measure-redshift relation of 17 FRB s,we estimate the value of the Hubble constant,H0=66.34±1.84km s-1 Mpc-1,under ACDM,with a difference of 0.55σand 3.30σ compared with the latest value obtained by Planck collaboration and SH0ES team respectively.Four different cosmological models are analyzed in this paper,and the corresponding results are obtained. |
