Cosmological analysis of a DGP stable model with $H(z)$ observations a revision

TL;DR

This study tests a DGP stable cosmological model against $H(z)$ and BAO data, finding it incompatible with observations of late cosmic acceleration, thus challenging its viability.

Contribution

It provides an observational analysis of the DGP stable model using $H(z)$ and BAO data, highlighting its inconsistency with late-time cosmic acceleration observations.

Findings

Observations do not favor the DGP stable model.

Tension exists between $\Lambda$ and $r_c$ constraints.

The model cannot adequately explain late cosmic acceleration.

Abstract

In this paper, we will present a Dvali-Gabadadze-Porrati stable model in order to perform an observational test using $H(z)$ data and radial BAO scale in the galaxy distribution. In this vein, we study the tension between constraints on the cosmological constant $\Lambda$ and the crossover scale $r_c$, which is associated with the DGP model. Our results show that observations do not favor the DGP stable model as a possible candidate to fit the observations of the late cosmic acceleration.
