An observational test of the plasma lensing effect using QSOs with and without MgII absorption
Xinzhong Er, Yiping Shu, Chenxu Liu
Radio wave propagation can be perturbed by compact ionized gas clumps through plasma lensing, which induces frequency dependent magnification and may distort the observed number co…

The Impact of Orbital Anisotropy Assumptions in Lensing-Dynamics Modeling
Yan Liang, Dandan Xu, Anowar J. Shajib +2
We investigate potential systematic biases introduced by assumptions regarding stellar orbital anisotropy in joint lensing-dynamics modeling. Our study employs the massive early-ty…
