Uncorrelated estimations of $H_0$ redshift evolution from DESI baryon acoustic oscillation observations

Understand

The Dark Energy Spectroscopic Instrument (DESI) collaboration recently released the first year data of baryon acoustic oscillations (BAOs).

• Based on the five different tracers, the cosmological constraint shows a hint of deviation from the standard $\Lambda$CDM model.
• In this letter, we combine the DESI BAOs with other cosmic probes to constrain the evolution of Hubble constant as a function of redshift in the flat $\Lambda$CDM model.
• The non-parametric method is used to estimate the value of Hubble constant at different redshift bins.
