Description
Scalar-tensor theories have shown great potential in inducing tailored modifications compared to cosmic evolution in the $\Lambda$CDM 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 $\Lambda$CDM 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,DESI and transversal baryonic acoustic oscillation data.
