Cosmology-independent Photon Mass Limits from Localized Fast Radio Bursts by using Artificial Neural Networks
Jing-Yu Ran, Bao Wang, Jun-Jie Wei
A hypothetical photon mass, , can produce a frequency-dependent vacuum dispersion of light, which leads to an additional time delay between photons with different frequencies…

Extragalactic Test of General Relativity from Strong Gravitational Lensing by using Artificial Neural Networks
Jing-Yu Ran, Jun-Jie Wei
This study aims to test the validity of general relativity (GR) on kiloparsec scales by employing a newly compiled galaxy-scale strong gravitational lensing (SGL) sample. We utiliz…
