Analysis
This paper investigates a late-time cosmological model within the Rastall theory, focusing on observational constraints on the Hubble parameter. It utilizes recent cosmological datasets (CMB, BAO, Supernovae) to analyze the transition from deceleration to acceleration in the universe's expansion. The study's significance lies in its exploration of a specific theoretical framework and its comparison with observational data, potentially providing insights into the universe's evolution and the validity of the Rastall theory.
Key Takeaways
- •Investigates late-time cosmology within the Rastall theory.
- •Uses CMB, BAO, and Supernovae data to constrain the Hubble parameter.
- •Demonstrates a redshift transition from deceleration to acceleration.
- •Provides an estimate for the current Hubble parameter: $H_0 = 66.945 \pm 1.094$.
