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…
Statistical analysis with cosmic-expansion-rate measurements and two-point diagnostics
Xiaogang Zheng, Marek Biesiada, Xuheng Ding +3
Direct measurements of Hubble parameters are very useful for cosmological model parameters inference. Based on them, Sahni, Shafieloo and Starobinski introduced a two-point…
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…
The distance sum rule from strong lensing systems and quasars - test of cosmic curvature and beyond
Jing-Zhao Qi, Shuo Cao, Sixuan Zhang +3
Testing the distance-sum-rule in strong lensing systems provides an interesting method to determine the curvature parameter using more local objects. In this paper, we apply…
Strongly gravitational lensed SNe Ia as multi-messengers: Direct test of the Friedmann-Lema\^ıtre-Robertson-Walker metric
Jing-Zhao Qi, Shou Cao, Marek Biesiada +3
We present a new idea of testing the validity of the Friedman-Lema\^ıtre-Robertson-Walker metric, through the multiple measurements of galactic-scale strong gravitational lensing s…
