Reassessing the Statistical Necessity of Stellar Velocity Anisotropy in Strong-Lensing Cosmology with Lens-by-Lens Photometric Constraints
Jian Hu, Yi Liu, Jian-Ping Hu +1
The stellar orbital anisotropy parameter () is a persistent systematic uncertainty in galaxy-scale strong gravitational lensing (SGL) cosmology. Typically fixed to iso…

A model-independent test of the cosmic distance-duality relation using galaxy clusters and Type Ia supernovae matched pairs
Jian Hu, Yi Liu, Jian-Ping Hu +1
The cosmic distance-duality relation (CDDR), expressed as , is a fundamental relation in cosmology connecting luminosity distance () and angular diame…

Testing cosmic anisotropy with Pade approximation and Pantheon+ sample
Jianping Hu, Jian Hu, Xuandong Jia +2
Cosmography can be used to constrain the kinematics of universe in a model-independent way. In this work, we attempted to combine the Pad approximations with the lat…
