Direct Estimate of the Post-Newtonian Parameter and Cosmic Curvature from Galaxy-scale Strong Gravitational Lensing
Jun-Jie Wei, Yun Chen, Shuo Cao +1
Einstein's theory of general relativity (GR) has been precisely tested on solar system scales, but extragalactic tests are still poorly performed. In this work, we use a newly comp…
Investigating the dynamical models of cosmology with recent observations and upcoming gravitational-wave data
Jie Zheng, Yun Chen, Tengpeng Xu +1
We explore and compare the capabilities of the recent observations of standard cosmological probes and the future observations of gravitational-wave (GW) standard sirens on constra…
Comparing the scalar-field dark energy models with recent observations
Tengpeng Xu, Yun Chen, Lixin Xu +1
We investigate the general properties of a class of scalar-field dark energy models (i.e., CDM models) which behave like cosmological trackers at early times. Particularly, we c…
Baryon acoustic oscillation, Hubble parameter, and angular size measurement constraints on the Hubble constant, dark energy dynamics, and spatial curvature
Joseph Ryan, Yun Chen, Bharat Ratra
In this paper we use all available baryon acoustic oscillation, Hubble parameter, and quasar angular size data to constrain six dark energy cosmological models, both spatially flat…
Assessing the effect of lens mass model in cosmological application with updated galaxy-scale strong gravitational lensing sample
Yun Chen, Ran Li, Yiping Shu +1
By comparing the dynamical and lensing masses of early-type lens galaxies, one can constrain both the cosmological parameters and the density profiles of galaxies. We explore the c…
Ultra-compact structure in intermediate-luminosity radio quasars: building a sample of standard cosmological rulers and improving the dark energy constraints up to
Shuo Cao, Xiaogang Zheng, Marek Biesiada +3
In this paper, we present a new compiled milliarcsecond compact radio data set of 120 intermediate-luminosity quasars in the redshift range . These quasars show negl…
