Geometric obstruction to resolving the Hubble tension: orthogonality of scale and shape in distance measurements
Zhihuan Zhou, Zhuang Miao, Sheng Bi +2
We identify a geometric obstruction to resolving the Hubble tension by combining early-time sound-horizon reduction with late-time smooth dark energy. Within CDM, the BAO--SN m…

Redshift-dependent Distance Duality Violation in Resolving Multidimensional Cosmic Tensions
Zhihuan Zhou, Zhuang Miao, Rong Zhang +3
In this work, we investigate whether violations of the distance-duality relation (DDR) can resolve the multidimensional cosmic tensions characterized by the and discrep…

What Prevents Resolving the Hubble Tension through Late-Time Expansion Modifications?
Zhihuan Zhou, Zhuang Miao, Sheng Bi +2
We demonstrate that Type Ia supernovae (SNe Ia) observations impose the critical constraint for resolving the Hubble tension through late-time expansion modifications. Applying the…
