Multi-axion like description of the dark sector in light of the Hubble and σ₈ tensions

Local methods of direct determination of the Hubble constant and $\sigma_8$ seem to conflict with the predictions made from the cosmic microwave background and $\Lambda$CDM. We propose a proof-of-concept model that models portions of the dark sector as several coupled axion-like fields, resulting in both early and late time departures from $\Lambda$CDM. We determine that the model successfully eliminates both the Hubble and $\sigma_8$ tensions, while remaining consistent with both the DESI survey and the BAO sound horizon.
