Chameleonic Generalized Brans--Dicke model and late-time acceleration

TL;DR

This paper explores a Chameleonic Generalized Brans--Dicke cosmological model, analyzing its ability to produce bouncing solutions and phantom crossing, and tests its viability against observational data like CRD and distance modulus.

Contribution

It introduces a novel Chameleonic Generalized Brans--Dicke model and evaluates its late-time acceleration features through theoretical analysis and observational tests.

Findings

The model exhibits bouncing solutions.

Phantom crossing is achieved in the model.

The model is consistent with CRD and distance modulus observations.

Abstract

In this paper we consider Chameleonic Generalized Brans--Dicke Cosmology in the framework of FRW universes. The bouncing solution and phantom crossing is investigated for the model. Two independent cosmological tests: Cosmological Redshift Drift (CRD) and distance modulus are applied to test the model with the observation.
