| contents | A simple and minimal extension of the standard cosmological $Λ$CDM model in which dark matter experiences an additional long-range scalar interaction is demonstrated to alleviate the long lasting Hubble-tension while letting primordial nucleosynthesis predictions unaffected and passing by construction all current local tests of general relativity. The theoretical formulation of this $Λβ$CDM model and its comparison to astrophysical observations are presented to prove its ability to fit existing data and potentially resolve the tension. |
