摘要：

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 ?CDM nor ?(& omega;)CDM cannot solve the Hubble tension.& COPY; 2023 Elsevier Inc.
