Duchaniya, Jackson Levi Said, B Mishra This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-6817456/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract Scalar-tensor theories have shown great potential in inducing tailored modifications compared to cosmic evolution in the ΛCDM model. We reconsider quintessence models in this work in the context of three driving potentials. We center the action of these models in the late Universe which leaves early ΛCDM cosmology unchanged. The effects show the potential of producing a faster expanding cosmology with a high Hubble constant. The models are constrained using the cosmic chronometer data, Pantheon plus, and transversal baryonic acoustic oscillation data. Full Text Additional Declarations No competing interests reported.
