Optimizing Gaussian Process Kernels Using Nested Sampling and ABC Rejection for H(z) Reconstruction

Jia-yan Jiang, Kang Jiao, Tong-Jie Zhang

Recent cosmological observations have achieved high-precision measurements of the Universe's expansion history, prompting the use of nonparametric methods such as Gaussian processe…

FLRW Kinematic-Induced Measurement of the Hubble Constant from Cosmic Chronometer and Redshift Drift Observations

Kang Jiao, Tong-Jie Zhang, Liang Gao +1

We present a geometric embedding method that exploits the exact kinematic relation z˙=H0​(1+z)−H(z) to transform redshift misalignment between Cosmic Chronometer (CC)…

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, Ωb​, within the framework of the ΛCDM model. Our analysis utilizes observational data on the effective optical…
