No Strong Evidence for Plasma Lensing in FRB 20240114A

Jiarui Niu, Xiaohui Liu, Nan Xu +33

FRB 20240114A is an extremely active repeating fast radio burst for which plasma lensing has been proposed to explain its burst-rate variations, spectral evolution, and apparently…

The magnetar model's energy crisis for a prolific repeating fast radio burst source

Jun-Shuo Zhang, Tian-Cong Wang, Pei Wang +61

Fast radio bursts (FRBs) are widely considered to originate from magnetars that power the explosion through releasing magnetic energy. Active repeating FRBs have been seen to produ…
