Radiation mechanism of Fast Radio Bursts
University of Texas at Austin
Fast radio bursts (FRBs) are millisecond duration transient events of unknown physical origin. At least a few FRBs are located at distances of several billion light years, and CHIME has established that there are many FRBs that repeat. Using very general arguments I will show that the radio emission is coherent, the magnetic field strength associated with the source of these events is 10e14 Gauss or more, and the electric field is of order 10e11 esu. I will describe recent works that magnetic field distortion and reconfiguration is responsible for the strong electric field and the coherent radiation produced in these enigmatic events. I will also address polarization properties of the well known repeater.
