Resolving the Hubble tension at late times with Dark Energy
read the original abstract
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.

Unifying Early and Late Dark Energy: Dynamical Requirements and Obstructions
Any unified early and late dark energy scenario with a single tracking scalar field requires a potential with three distinct slopes arranged in a steep-steeper-shallow hierarchy.

Alleviating the Hubble tension with the $\Lambda_{\omega_s}$CDM model
Λ_{ω_s}CDM adds a subdominant early barotropic fluid with fitted ω_s ≈ 0.294 and Ω_s ≈ 1.62×10^{-5}, producing H0 = 71.51 km/s/Mpc from MCMC fits to Planck 2018, DESI DR2, and Pantheon+SH0ES data.
