Zadorozhna L. Electrodynamical and gravitational detection of cosmic strings

The observed characteristics cosmic strings's gravitational and electromagnetic action are derived. The analytical relations of magnification are derived for some configurations of loops, their critical curves are derived and considered. The detecting possibility of loops is estimated. It is established relativistic motion and interaction between superconducting cosmic string and cosmic plasma and it is developed a model of production the relativistic bow shock round string loop, calculated the expected nonthermal radiation fluxes of electrons accelerated by bow shock wave. The influence of relativistic effects on the emission of nearcusp superconducting cosmic string loop's regions is investigated.
