HXMT identification of a non-thermal X-ray burst from SGR J1935+2154 and with FRB 200428
Fast radio bursts (FRBs) are short pulses observed in the radio band from cosmological distances1. One class of models invokes soft gamma-ray repeaters (SGRs), or magnetars, as the sources of FRBs2. Some radio pu...
