Observational constraints on a modified-gravity model with an exponential function of the curvature using the expansion history, the RSD, and the Pantheon+SH0ES data

Mario A. Acero, A. Oliveros

Considering a well-motivated $f (R)$ modified-gravity model, in which an exponential function of the curvature is included, in this paper we implement a statistical data analysis to…

Cosmological dynamics and observational constraints on a viable $f (Q)$ non-metric gravity model

A. Oliveros, Mario A. Acero

Inspired by an exponential $f (R)$ gravity model studied in the literature, in this work we introduce a new and viable $f (Q)$ gravity model, which can be represented as a perturbati…

A viable $f (R)$ gravity model without oscillations in the effective dark energy

A. Oliveros

In this study, we propose a reparameterization of a specific viable $f (R)$ gravity model to represent it as a perturbation of the $Λ$ CDM model. The $f (R)$ gravity model under consi…
