Modelling Time-varying Dark Energy with Constraints from Latest Observations
Qing-Jun Zhang, Yue-Liang Wu
We introduce a set of two-parameter models for the dark energy equation of state (EOS) to investigate time-varying dark energy. The models are classified into two types acco…
Time-Varying Dark Energy Constraints From the Latest SN Ia, BAO and SGL
Qing-Jun Zhang, Yue-Liang Wu
Based on the latest SNe Ia data provided by Hicken et al. (2009) with using MLCS17 light curve fitter, together with the Baryon Acoustic Oscillation(BAO) and strong gravitational l…
Dark Energy and Hubble Constant From the Latest SNe Ia, BAO and SGL
Qing-Jun Zhang, Yue-Liang Wu
Based on the latest MLCS17 SNe Ia data provided by Hicken et al. (2009), together with the Baryon Acoustic Oscillation (BAO) and strong gravitational lenses (SGL), we investigate t…
Constraining Dark Energy From Splitting Angle Statistic of Strong Gravitational Lenses
Qing-Jun Zhang, Ling-Mei Cheng, Yue-Liang Wu
Utilizing the CLASS statistical sample, we investigate the constraint of the splitting angle statistic of strong gravitational lenses(SGL) on the equation-of-state parameter $w=p/ρ…
