Model-independent Constraints on Cosmic Curvature and Opacity
Guo-Jian Wang, Jun-Jie Wei, Zheng-Xiang Li +2
In this paper, we propose to estimate the spatial curvature of the universe and the cosmic opacity in a model-independent way with expansion rate measurements, , and type Ia…
Strongly lensed repeating Fast Radio Bursts as precision probes of the universe
Zhengxiang Li, He Gao, Xu-Heng Ding +2
Fast Radio bursts (FRBs), bright transients with millisecond durations at GHz and typical redshifts probably , are likely to be gravitationally lensed by intervening g…
Test of the FLRW metric and curvature with strong lens time delays
Kai Liao, Zhengxiang Li, Guo-Jian Wang +1
We present a new model-independent strategy for testing the Friedmann-Lema\^ıtre-Robertson-Walker metric and constraining cosmic curvature, based on future time delay measurements…
Evolutions and Calibrations of Long Gamma-Ray Bursts Luminosity Correlations Revisited
Guo-Jian Wang, Hai Yu, Zheng-Xiang Li +2
Luminosity correlations of long Gamma-ray bursts (GRB) are extensively proposed as an effective complementarity to trace the Hubble diagram of Universe at high redshifts, which is…
