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…
Constraints on Baryon Density from the Effective Optical Depth of High-Redshift Quasars
Wen-Fei Liu, Yuan-Bo Xie, Zhi-E Liu +4
We present constraints on the baryonic matter density parameter, , within the framework of the CDM model. Our analysis utilizes observational data on the effective optical…
A Non-parametric Reconstruction of the Hubble Parameter Based on Radial Basis Function Neural Networks
Jian-Chen Zhang, Yu Hu, Kang Jiao +5
Accurately measuring the Hubble parameter is vital for understanding the expansion history and properties of the universe. In this paper, we propose a new method that supplements t…
Likelihood-free Cosmological Constraints with Artificial Neural Networks: An Application on Hubble Parameters and SNe Ia
Yu-Chen Wang, Yuan-Bo Xie, Tong-Jie Zhang +3
The errors of cosmological data generated from complex processes, such as the observational Hubble parameter data (OHD) and the Type Ia supernova (SN Ia) data, cannot be accurately…
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…
