- W3190202479 abstract "One of the most favorable extensions of General Relativity is the [Formula: see text] gravity. [Formula: see text] gravity in Palatini formalism can be a realistic alternative to the dark energy problem. In this work, we study a recently introduced dark energy [Formula: see text] gravity model along with two other models in cosmological perspectives under the Palatini formalism. First, we study the cosmic expansion history of these models with the help of the important cosmographic parameters, such as the Hubble parameter, luminosity distance, effective equation of state, etc. This study shows that the new model behaves similarly with the other two models as well as with the [Formula: see text]CDM model in some respects in the early or very early phases of the universe. It could predict the present accelerated expansion of the universe somewhat differently from the other models with a peculiar future history of the universe. Within a constrained range of parameters all models show a good agreement with the Union2.1 luminosity distance data. However, the new model shows a quite satisfactory agreement in the whole range of its allowed parameters than that of the other two models. We also obtain cosmological constraints on these models from the observed Hubble data. Further, models have been tested by using [Formula: see text] test and statefinder diagnostics. These diagnostics especially the statefinder diagnostic shows that the evolutionary differences between these models are distinct. The evolutionary trajectories of the new model are completely different from the other two models we have considered." @default.
