The Magnified Waltz: Simulating Light Curves of Binary Stars Passing through Micro-Caustics in Strong Lensing Galaxy Clusters
Wenwen Zheng, Xiaoting Fu, Yang Chen +5
Individual stars located near the caustics of galaxy clusters can undergo extreme magnification when crossing micro-caustics, rendering them observable even at cosmological distanc…
Wave effect of gravitational waves intersected with a microlens field II: an adaptive hierarchical tree algorithm and population study
Xikai Shan, Guoliang Li, Xuechun Chen +3
The gravitational lensing wave effect generated by a microlensing field embedded in a lens galaxy is an inevitable phenomenon in strong lensed gravitational waves (SLGWs). This eff…
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…
