Extragalactic test of General Relativity with time-delay gravitational lenses
Wuzheng Guo, Shuo Cao, Qiumin Wang +4
Strong gravitational lensing, a key prediction of General Relativity (GR), offers a unique environment for examining alternative modified gravity theories. In this Letter, we emplo…

New tests of cosmic distance duality relation with DESI 2024 BAO observations
Qiumin Wang, Shuo Cao, Jianyong Jiang +5
In this paper, we test the cosmic distance duality relation (CDDR), as required by the Etherington reciprocity theorem, which connects the angular diameter distance and the luminos…

Newest measurements of Hubble constant from DESI 2024 BAO observations
Wuzheng Guo, Qiumin Wang, Shuo Cao +6
In this Letter, we use the latest results from the Dark Energy Spectroscopic Instrument (DESI) survey to measure the Hubble constant. Baryon acoustic oscillation (BAO) observations…
