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…
Ultra-compact structure in radio quasars as a cosmological probe: a revised study of the interaction between cosmic dark sectors
Xiaogang Zheng, Marek Biesiada, Shuo Cao +2
A new compilation of angular-size/redshift data for compact radio quasars from very-long-baseline interferometry (VLBI) surveys motivates us to revisit the interaction betwee…
Precision cosmology from future lensed gravitational wave and electromagnetic signals
Kai Liao, Xi-Long Fan, Xu-Heng Ding +2
The standard siren approach of gravitational wave cosmology appeals to the direct luminosity distance estimation through the waveform signals from inspiralling double compact binar…
Test of parametrized post-Newtonian gravity with galaxy-scale strong lensing systems
Shuo Cao, Xiaolei Li, Marek Biesiada +3
Based on a mass-selected sample of galaxy-scale strong gravitational lenses from the SLACS, BELLS, LSD and SL2S surveys and using a well-motivated fiducial set of lens-galaxy param…
