Abstract: A superconducting cosmic string loop can carry such a large current ≈ 1020 A which causes a strong magnetic field around it. The motion of the loop yields an electric field which accelerates charged particles. A simple model for the acceleration mechanism is presented. It is shown that particles may get ultra-high-energies ∼ 1020 eV and their integral energy spectrum is proportional toe−1/2. The expected spectrum for reasonable parameters of the string is consistent with experiments. Constraints on the radius of the loop are also discussed.

Gravitational radiation from cosmic strings
TL;DR: The momentum radiation rate from loops is calculated and it is shown that cosmological loops formed with sufficiently small initial velocities are slowed down by dynamical friction and do not rocket away.

Cosmological effects of superconducting strings
TL;DR: In this article, it was shown that the luminosity in electromagnetic radiation of an oscillating current-carrying loop may substantially exceed that in gravitational radiation, leading to the possibility that such loops may heat their surroundings, generating large, dense spherical shells of gas.

Superconducting cosmic strings
TL;DR: In this article, the authors proposed a string model for two recently discovered radio sources, the ''thread'' in the galactic center and the source G357.7-0.1, and predict that the filaments in these sources should move at relativistic speeds.
