Double-peaked Pulse Profile of FRB 200428: Synchrotron Maser from Magnetized Shocks Encountering a Density Jump

no code implementations28 Oct 2020 Di Xiao, Zi-Gao Dai

Very recently a fast radio burst (FRB) 200428 associated with a strong X-ray burst from the Galactic magnetar SGR 1935+2154 has been detected, which is direct evidence supporting the magnetar progenitor models of FRBs.

Repeating Fast Radio Bursts from Pulsar-Asteroid Belt Collisions: Frequency Drifting and Polarization

no code implementations27 Oct 2020 Ze-Nan Liu, Wei-Yang Wang, Yuan-Pei Yang, Zi-Gao Dai

Following the model of \citet{dai 2016} who proposed that repeating FRBs may originate from a slowly-rotating, old-aged pulsar colliding with an asteroid belt around a stellar-mass object, we focus on the prediction of time--frequency drifting and polarization.
