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…
Calibrating the effective magnitudes of type Ia supernovae with a model-independent method
Jian Hu, Jian-Ping Hu, Zhongmu Li +2
This research explores the correlation between the absolute magnitude and the redshift of Type Ia supernovae (SNe Ia) with a model-independent approach. The Pantheon sample of SNe…
Exploring the possible evolution of the mass density power-law index of strong gravitational lenses with a model-independent method
Jian Hu
In this work, we adopt a cosmological model-independent approach for the first time to test the question of whether the mass density power-law index() of the strong gravitationa…
A Distance-Deviation Consistency and Model-Independent Method to Test the Cosmic Distance-Duality Relation
C. C. Zhou, J. Hu, M. C. LI +2
A distance-deviation consistency and model-independent method to test the cosmic distance duality relation (CDDR) is provided. The method is worth attention on two aspects: firstly…
The Properties of Hα Emission-Line Galaxies at z = 2.24
F. X. An, X. Z. Zheng, W. -H. Wang +9
Using deep narrow-band and -band imaging data obtained with CFHT/WIRCam, we identify a sample of 56 H emission-line galaxies (ELGs) at with the 5 dept…
