Latent-Space Gaussian Processes for Dark-Energy Reconstruction from Observational \(H(z)\) Data
Jia-yan Jiang, Wei Hong, Tong-jie Zhang
Using the 37-point cosmic-chronometer subset of observational Hubble parameter (OHD) data, we develop a Bayesian Gaussian-process framework to reconstruct the normalized dark-energ…
Tightening Cosmological Constraints Within and Beyond CDM Using Gamma-Ray Bursts Calibrated with Type Ia Supernovae
Wei Hong, Luca Izzo, Massimo Della Valle +3
Context. Gamma-ray bursts (GRBs) reach redshifts beyond Type Ia supernovae (SNe Ia) and can extend distance measurements into the early Universe, but their use as distance indicato…
Exploring the Cosmological Model Degeneracy with a new evaluate factor G
Yuan-bo Xie, Yun-dong Wu, Wei Hong +1
In the context of fitting cosmological models, parameter degeneracy remains a central issue. This paper critically examines traditional methods for constraining parameters and focu…
Polarization Properties of the Electromagnetic Response to High-frequency Gravitational Wave
Jian-Kang Li, Wei Hong, Tong-Jie Zhang
Electromagnetic waves (EMWs) can be generated by gravitational waves (GWs) within a magnetic field via the Gertsenshtein effect. The conversion probability between GWs and EMWs can…
Cosmic Dynamics in Einstein-Cartan Theory: Analysing Hubble Tension through Curvature and Torsion field
Yun-Dong Wu, Wei Hong, Tong-Jie Zhang
The Hubble tension refers to the significant discrepancy in the Hubble constant obtained from two different measurement methods in cosmology. One method derives data from t…
A Stochastic Approach to Reconstructing the Speed of Light in Cosmology
Cheng-Yu Zhang, Wei Hong, Yu-Chen Wang +1
The Varying Speed of Light (VSL) model describes how the speed of light in a vacuum changes with cosmological redshift. Despite numerous models, there is little observational evide…
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…
