Torsion cosmology in the light of DESI, supernovae and CMB observational constraints
Tonghua Liu, Xiaolei Li, Tengpeng Xu +2
In this work, we investigate a torsion-based cosmological model within the Einstei-Cartan framework, constrained by the latest combined datasets including DESI DR2 BAO, PantheonPlu…
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…
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,…
Testing the speed of light over cosmological distances: the combination of strongly lensed and unlensed supernova Ia
Shuo Cao, Jingzhao Qi, Marek Biesiada +3
Probing the speed of light is as an important test of General Relativity but the measurements of using objects in the distant universe have been almost completely unexplored. I…
What is parameterized diagnostics telling us in light of recent observations?
Jing-Zhao Qi, Shuo Cao, Marek Biesiada +4
In this paper, we propose a new parametrization of diagnostics and show how the most recent and significantly improved observations concerning the and SN Ia measurem…
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…
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…
