Hubble tension and matter inhomogeneities: a theoretical perspective

Abstract

We have studied how local density perturbations could reconcile the Hubble tension. We reproduced a local void through a perturbed FLRW metric with a potential $\Phi$ which depends on both time and space. This method allowed us to obtain a perturbed luminosity distance, which is compared with both local and cosmological data. However, when constraining local cosmological parameters with previous results, we found that neither $\Lambda$CDM nor $\Lambda (\omega )$CDM cannot solve the Hubble tension.
