Constraining on the non-standard cosmological models combining the observations of high-redshift quasars and BAO
Ziqiang Liu, Tonghua Liu, Xinyi Zhong +2
In this work, we studied four types of cosmological models with different mechanisms driving the accelerated expansion of the universe, include Braneworld models, Chaplygin Gas mod…
Distinguishing CDM from evolving dark energy with the future gravitational-wave space-borne detector DECIGO
Yuting Liu, Shuo Cao, Xiaogang Zheng +3
The two point diagnostics was proposed as a litmus test of CDM model and measurements of cosmic expansion rate have been extensively used to perform this…
Hubble diagram at higher redshifts: Model independent calibration of quasars
Xiaolei Li, Ryan E. Keeley, Arman Shafieloo +4
In this paper, we present a model-independent approach to calibrate the largest quasar sample. Calibrating quasar samples is essentially constraining the parameters of the linear r…
Multiple measurements of quasars acting as standard probes: model independent calibration and exploring the Dark Energy Equation of States
Xiaogang Zheng, Shuo Cao, Marek Biesiada +3
Recently, two classes of quasar samples were identified, which are promising as new cosmological probes extending to higher redshifts. The first sample uses the nonlinear relation…
Model-independent constraints on cosmic curvature: implication from the future gravitational wave observation DECIGO
Xiaogang Zheng, Shuo Cao, Yuting Liu +5
A model-independent test of the cosmic curvature parameter is very important in cosmology. In order to estimate cosmic curvature from cosmological probes like standard candle…
Multiple measurements of quasars acing as standard probes: exploring the cosmic distance duality relation at higher redshift
Xiaogang Zheng, Kai Liao, Marek Biesiada +3
General relativity reproduces main current cosmological observations, assuming the validity of cosmic distance duality relation (CDDR) at all scales and epochs. However, CDDR is po…
