Radio Broadcasts from Superconducting Strings
  Superconducting cosmic strings can give transient electromagnetic signatures
that we argue are most evident at radio frequencies. We investigate the three
different kinds of radio bursts from cusps, kinks, and kink-kink collisions on
superconducting strings. We find that the event rate is dominated by kink
bursts in a range of parameters that are of observational interest, and can be
quite high (several a day at 1 Jy flux) for a canonical set of parameters. In
the absence of events, the search for radio transients can place stringent
constraints on superconducting cosmic strings.
