Redshift-binned constraints on the Hubble constant under CDM, CPL, and Padé cosmography
Zhi-Yuan Mo, Kang Jiao, Tong-Jie Zhang
Motivated by recent claims of a possible redshift dependence in late-Universe determinations of the Hubble constant (H_0), we test the robustness of this behavior using multiple co…

Probing the Hubble Tension with an Infinite-Future Condition on the Hubble Parameter
Yuan-Bo Xie, Cheqiu Lyu, Zhiyuan Mo +2
We study the impact of imposing an infinite-future condition on Gaussian-process (GP) reconstructions of from 37 cosmic-chronometer measurements. Implementing the asymptotic…
