Scaling solutions as Early Dark Energy resolutions to the Hubble tension

The Hubble tension is one of the most important open challenges in cosmology, presenting a significant difference in the inferred values of the Hubble constant from observations at both high and low redshifts. One possible solution involves so-called Early Dark Energy (EDE), which introduces an extra burst of energy around matter-radiation equality that fades away faster than radiation. In this talk, I'll show how certain scalar field models that present scaling regimes can help create the Early Dark Energy spike we are looking for. Then, I'll expand this result to include more general models involving both Quintessence and K-essence, evaluating their potential in addressing the Hubble tension.
