Refractive lensing of scintillating FRBs by sub-parsec cloudlets in the multi-phase CGM

Dylan L. Jow, Xiaohan Wu, Ue-Li Pen

We consider the refractive lensing effects of ionized cool ($T\sim 10^4\mathrm{K}$) gas cloudlets in the circumgalactic medium (CGM) of galaxies. In particular, we discuss the comb…
