英文摘要We present a new parameterized Hubble function and employ observational data from Hubble, Pantheon, and Baryon Acoustic Oscillations to constrain model parameters. The proposed method is thoroughly validated against these datasets, demonstrating a robust fit to the observational data. The obtained best-fit values are H-0 = 67.5(-1.6)(+1.3) km s(-1)Mpc(-1), ohm(m0) = 0.2764 +/- 0.0094, and alpha = 0.33 +/- 0.22, consistent with the Planck 2018 results, highlighting the existence of Hubble tension.
