Probing modified gravity theories with multiple measurements of high-redshift quasars
Yujie Lian, Shuo Cao, Marek Biesiada +3
In this paper, we quantify the ability of multiple measurements of high-redshift quasars (QSOs) to constrain several theories of modified gravity, including the Dvali-Gabadadze-Por…

Investigating the relationship between cosmic curvature and dark energy models with the latest supernova sample
Chao Gao, Yun Chen, Jie Zheng
We investigate the relationship between the cosmic curvature and the model of dark energy (hereafter DE) with the recent Type Ia supernovae (hereafter SNe Ia) data, i.e., the Panth…
