Fast Radio Bursts from the Decay of Cosmic String Cusps
  We explore the possibility that Fast Radio Bursts are due to the annihilation
of cusps on cosmic string loops. We compute the energy released in the
annihilation events in the radio region, the expected event rate, and the time
scale of the bursts. We find that the energy and event rates are sufficiently
high and the time scale is sufficiently small to explain the current data. We
predict how the event rate will change as the resolution of telescopes
improves. Since the burst rate depends on the string tension, future data will
allow the determination of the tension.
