Interacting dark energy axions in light of the Hubble tension*

A current problem within the ΛCDM framework is the tension between late and early time measurements of the Hubble parameter today, H₀.  We entertain the possibility that dark energy modeled as multiple interacting axion-like-particle species can alleviate the current Hubble tension.  We then test these parameters against the milder tension between the CMB and large scale structure (LSS) observations of σ₈ to ensure that these models do not exacerbate the tension.  We find that there exist parameter spaces for models of two and three axion-like-particles which can potentially alleviate the Hubble tension as well as the σ₈ tension.
