Sparks from Superconducting Cosmic Strings

Cosmic strings would be part of networks created during phase transitions in the early universe. These networks could even be composed of cosmic superstrings. The cusp or kink of a superconducting cosmic string is expected to produce a burst of electromagnetic radiation. Such a burst or ``spark'' would be relativistically beamed as a low frequency electromagnetic pulse. Results of a numerical simulation estimating the event rate of such ``sparks'' detectable with current radio telescopes will be presented.
