Scattering of Strong Radio Waves by Particles in Strongly Magnetized Plasmas and Implications for Fast Radio Bursts
Yuanhong Qu, Pawan Kumar
Fast Radio Bursts (FRBs) are millisecond-duration radio transients that are widely believed to originate within magnetar magnetospheres. Large-amplitude radio waves associated with…

Polarization Angle Orthogonal Jumps in Fast Radio Bursts
Yuanhong Qu, Bing Zhang, Pawan Kumar
Recently, polarization angle (PA) orthogonal jumps over millisecond timescales were discovered from three bursts of a repeating fast radio burst source FRB 20201124A by the FAST te…

The Origins of Narrow Spectra of Fast Radio Bursts
Pawan Kumar, Yuanhong Qu, Bing Zhang
Observations find that some fast radio bursts (FRBs) have extremely narrow-band spectra, i.e., . We show that when the angular size of the emission region is larger t…
