Redshift-Dependent Intrinsic Dispersion in the Quasar UV/X-ray Luminosity Relation
Jiaze Gao, Jianping Hu, Yun Chen +2
Accurate modeling of the intrinsic dispersion in the quasar UV/X-ray luminosity relation is essential for reliable cosmological inference. We investigate its redshift dependence us…
Cosmological application of the lens-redshift probability distribution with improved galaxy-scale gravitational lensing sample
Hui Li, Yun Chen
We conduct the cosmological analysis by using the lens-redshift distribution test with updated galaxy-scale strong lensing sample, where the considered scenarios involve three typi…
Diagnosing the cosmic coincidence problem and its evolution with recent observations
Jie Zheng, Yun Chen, Tengpeng Xu +1
In the framework of a phenomenological cosmological model with the assumption of ( and are the energy densities of dark energy and matter,…
Probing modified gravity theories with multiple measurements of high-redshift quasars
Yujie Lian, Shuo Cao, Marek Biesiada +3
In this paper, we quantify the ability of multiple measurements of high-redshift quasars (QSOs) to constrain several theories of modified gravity, including the Dvali-Gabadadze-Por…
Investigating the relationship between cosmic curvature and dark energy models with the latest supernova sample
Chao Gao, Yun Chen, Jie Zheng
We investigate the relationship between the cosmic curvature and the model of dark energy (hereafter DE) with the recent Type Ia supernovae (hereafter SNe Ia) data, i.e., the Panth…
Determining the Hubble constant from Hubble parameter measurements
Yun Chen, Suresh Kumar, Bharat Ratra
We use 28 Hubble parameter, , measurements at intermediate redshifts to determine the present-day Hubble constant in four cosmological models. We…
