Abstract: We consider a quintessence field which transitions from a matter-like to a cosmological constant behavior between recombination and the present time. We aim at easing the tension in the measurement of the present Hubble rate, and we assess the ΛCDM model properly enlarged to include our quintessence field against cosmological observations. The model does not address the scope we proposed, so we comment on the explanations for this. This result allows us to exclude a class of quintessential models in view of the current tension over different measurements of the Hubble rate.
