| 抄録: | In this letter we propose a reduction of the H₀ tension puzzle by means of a theory of minimally modified gravity which is dubbed VCDM. After confronting the theory with the data, a transition in the expansion history of the universe in the low-redshift z ≃ 0.3 is found. From the bestfit values the total fitness parameter is improved by Δx² = 33.41 , for the data set considered. We then infer the local Hubble expansion rate today within this theory by means of low redshift Pantheon data. The resulting local Hubble expansion rate today is H₀[loc] = 73.69 ± 1.4. Hence the tension is reduced within the VCDM theory. |
