论文摘要

最近的观察结果表明,CMB和类星体偶极子之间的张力为$4.9σ$。这种张力挑战了宇宙原则。我们建议,如果我们生活在Gigaparsec量表上,则可以调和CMB和Quasar偶性张力。这是因为我们不太可能生活在空白的中心。从中心偏移10 \%以内的A将在其偶极性各向异性中对类星体和CMB的影响不同。当我们考虑一个大而厚的空隙时,我们的设置也可以缓解哈勃张力。

Recent observations indicate a $4.9σ$ tension between the 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.
