A common explanation of the Hubble tension and anomalous cold spots in the CMB

Understand

The standard cosmological paradigm narrates a reassuring story of a universe currently dominated by an enigmatic dark energy component.

• Disquietingly, its universal explaining power has recently been challenged by, above all, the $\sim4\sigma$ tension in the values of the Hubble constant.
• Another, less studied anomaly is the repeated observation of integrated Sachs-Wolfe imprints $\sim5\times$ stronger than expected in the $\Lambda$CDM model from R>100 $Mpc/h$ super-structures.
• Here we show that the inhomogeneous AvERA model of emerging curvature is capable of telling a plausible albeit radically different story that explains both observational anomalies without dark energy.
