Testing and selecting cosmological models with ultra-compact radio quasars
Xiaolei Li, Shuo Cao, Xiaogang Zheng +3
In this paper, we place constraints on four alternative cosmological models under the assumption of the spatial flatness of the Universe: CPL, EDE, GCG and MPC. A new compilation o…
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…
New observational constraints on cosmology from radio quasars
Jing-Zhao Qi, Shuo Cao, Marek Biesiada +2
Using a new recently compiled milliarcsecond compact radio data set of 120 intermediate-luminosity quasars in the redshift range , whose statistical linear sizes sho…
Cosmological investigation of multi-frequency VLBI observations of ultra-compact structure in radio quasars
Shuo Cao, Marek Biesiada, Jingzhao Qi +5
In this paper, we use multi-frequency angular size measurements of 58 intermediate-luminosity quasars reaching the redshifts and demonstrate that they can be used as stan…
A new test of gravity with the cosmological standard rulers in radio quasars
Tengpeng Xu, Shuo Cao, Jingzhao Qi +3
As an important candidate gravity theory alternative to dark energy, a class of modified gravity, which introduces a perturbation of the Ricci scalar in the Einstein-Hil…
Milliarcsecond compact structure in radio quasars and the geometry of the universe
Shuo Cao, Jingzhao Qi, Marek Biesiada +4
In this paper, by using the recently compiled set of 120 intermediate-luminosity quasars (ILQSO) observed in a single-frequency VLBI survey, we propose an improved model-independen…
