Model Description
Nambu-Goto (infinitely thin, idealised) cosmic strings generically form cusps-portions of the string which fold back onto themselves and move at the speed of light. The cusps decay to form a beam of coherent radiation, where the emission can ostensibly be of any energy and frequency range. As such, cusp decay has been considered as an FRB origin. The event rate, timescale, and flux are shown to be consistent with FRB data.
