Resolving the Hubble tension at late times with Dark Energy

Within the standard cosmological model, the presence of Dark Energy (DE) is the only structural difference between the early and late times Universe. While its presence is in full display at late times, it is irrelevant at early times, especially when all other physical ingredients of the standard model are contributing to the formation of CMB anisotropies. This makes DE a natural candidate to try to solve cosmological tensions between measurements from these two different epochs. We will analyze how DE presence affects relevant cosmological observables and how it could change them. This will allow us to discuss how late-time measurements constrain DE models that aim to resolve the Hubble constant tension and the achievable performances of these models.
