Cosmology in the Hoyle Narlikar gravity

Abstract: In this paper, we study the late time cosmic acceleration of the Quintessence model within the framework of Hoyle Narlikar Gravity, consisting of a creation field. Using the Hubble tension as a function of the density parameter for matter, the density parameter for radiation, and the density parameter for dark energy in the covariant formulation, we find the gravitational field equations in the spatially flat, homogeneous, and isotropic spacetime to examine the dynamical mechanism that leads to cosmic acceleration in the late-time universe. We analyze the observational constraints on the late-time density parameters using various recent observational datasets, including the Hubble datasets, Pantheon+, and joint compilation, Pantheon++BAO. Consequently, it is explicitly demonstrated that late-time cosmic acceleration can be consistent with recent observational data in Hoyle Narlikar Gravity with non-minimal matter interaction. In contrast with other modified theories of gravity, it is observed that the creation field theory with non-minimal matter interaction renders more compact constraints on the Hubble tension together with density parameters, and extensively explains the accelerating expansion of the universe, which makes it a more plausible option compared to the {\Lambda}CDM model. Furthermore, the w dw phase analysis confirms alternating thawing and freezing behaviour of the model, with all trajectories ultimately converging toward the {\Lambda}CDM point, thereby confirming the model stability and the observational consistency.
