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…
High Sensitivity Methodologies to Detect Radio Band Gravitational Waves
Wei Hong, Peng He, Tong-Jie Zhang +2
Gravitational waves (GWs) can resonate with magnetic fields through the Gertsenshtein-Zeldovich effect, producing electromagnetic signals at the same frequency. In pulsar magnetosp…
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…
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…
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…
