Plasma lensing interpretation of FRB 20201124A bursts at the end of September 2021
Xuechun Chen, Bin Hu, Pei Wang +3
When the radio photons propagate through a non-uniform electron density volume, the plasma lensing effect can induce an extreme magnification to the observed flux at certain freque…

Theoretical Analysis of Random Scattering Induced by Microlensing
Wenwen Zheng, Hou-Zun Chen, Xuechun Chen +1
Theoretical investigations into the deflection angle caused by microlenses offer a direct path to uncovering principles of the cosmological microlensing effect. This work specifica…

Simulation Of The Microlensing Effect Near The Critical Curve Of The Galaxy Cluster
Xuliu Yang, Xuechun Chen, Wenwen Zheng +1
In the smooth mass distribution model, the critical curve represents a line with magnification divergence on the image plane in a strong gravitational lensing system. Considering t…
