Fast radio bursts (FRBs) are short (millisecond) pulses originating from enigmatic sources at extragalactic distances so far lacking a detection in other energy bands. Magnetized neutron stars (magnetars) have been considered as the powering FRBs, but connection is controversial because of differing energetics and lack X-ray detections with similar characteristics two classes.
