Cosmic Dynamics in $F(R,\phi)$ Gravity

TL;DR

This paper explores cosmological models within $F(R, heta)$ gravity, demonstrating bouncing universe scenarios and phantom crossing, while validating the model against observational tests like CRD and supernova data.

Contribution

It introduces specific $F(R, heta)$ gravity models that exhibit bouncing behavior and phantom crossing, validated by observational tests.

Findings

Bouncing behavior can occur in $F(R, heta)$ gravity models.

The EoS parameter can cross the phantom divide.

Model parameters satisfy CRD and supernova distance tests.

Abstract

In this paper we consider FRW cosmology in $F(R,\phi)$ gravity. It is shown that in particular cases the bouncing behavior may appears in the model whereas the equation of state (EoS) parameter may crosses the phantom divider. For the dynamical universe, quantitatively we also find parameters in the model which satisfies two independent tests:the model independent Cosmological Redshift Drift (CRD) test and the type Ia supernova luminosity distances.
