Reconciling cosmic dipolar tensions with a gigaparsec void

Recent observations indicate a $4.9\ensuremath{\sigma}$ tension between the cosmic microwave background (CMB) and quasar dipoles. This tension challenges the cosmological principle. We propose that if we live in a gigaparsec-scale void, the CMB and quasar dipolar tension can be reconciled. This is because we are unlikely to live at the center of the void, and a within 10% offset from the center will impact the quasars and CMB differently in their dipolar anisotropies. As we consider a large and thick void, our setup can also ease the Hubble tension.

Abstract

Recent observations indicate a $4.9\ensuremath{\sigma}$ tension between the cosmic microwave background (CMB) and quasar dipoles. This tension challenges the cosmological principle. We propose that if we live in a gigaparsec-scale void, the CMB and quasar dipolar tension can be reconciled. This is because we are unlikely to live at the center of the void, and a within 10% offset from the center will impact the quasars and CMB differently in their dipolar anisotropies. As we consider a large and thick void, our setup can also ease the Hubble tension.
