Hierarchical Gaussian-process reconstruction of late-time expansion with DESI BAO and compressed Planck priors
Yu-Hao Mu, Zhihuan Zhou, Enkun Li
We reconstruct the late-time expansion history with a hierarchical Gaussian process (GP) that co-samples the kernel hyperparameters together with $(\Hzero,\Om,\Ok,ω_b h^2…
Geometric obstruction to resolving the Hubble tension: orthogonality of scale and shape in distance measurements
Zhihuan Zhou, Zhuang Miao, Sheng Bi +2
We identify a geometric obstruction to resolving the Hubble tension by combining early-time sound-horizon reduction with late-time smooth dark energy. Within CDM, the BAO--SN ma…
Cosmological Constraints on Thermal Friction of Axion Dark Matter
Gang Liu, Yuhao Mu, Zhihuan Zhou +1
In this paper, we investigate the process in which axion dark matter undergoes thermal friction, resulting in energy injection into dark radiation, with the aim of mitigating the H…
Kinetically Coupled Scalar Fields Model and Cosmological Tensions
Gang Liu, Zhihuan Zhou, Yuhao Mu +1
In this paper, we investigate the kinetically coupled early dark energy (EDE) and scalar field dark matter to address cosmological tensions. The EDE model presents an intriguing th…
A Measurement of Hubble Constant Using Cosmographic Approach from Fast Radio Bursts and SNe Ia
Jiaze Gao, Zhihuan Zhou, Minghui Du +3
The Hubble constant is a crucial parameter in cosmology. However, different cosmic observations have resulted in varying posterior results for , leading to what is k…
Alleviating Cosmological Tensions with a Coupled Scalar Fields Model
Gang Liu, Zhihuan Zhou, Yuhao Mu +1
In this paper, we investigate the interaction between early dark energy (EDE) and scalar field dark matter, proposing a coupled scalar fields model to address the Hubble tension an…
