Emission of gravitational waves by superconducting cosmic strings

We study the gravitational radiation emission efficiency $\Gamma$ of superconducting cosmic strings. demonstrate, by using a solvable model transonic strings, that presence current leads to suppression cusps, kinks and different types loops. also show that, when is present, spectrum loops with cusps exponentially suppressed as harmonic mode increases, thus being significantly from power law currentless Furthermore, we establish phenomenological relationship between value on conjecture this relation should be valid for an arbitrary type current-carrying string. use result potential impact stochastic wave background generated strings additional degrees freedom both amplitude shape may affected.
