| Popis: | Cosmic strings are topological defects, relicts of the early Universe, which can be formed during phase transitions of fields with spontaneous broken symmetry. It was shown that extragalactic fast radio bursts could be explained as radiation from superconducting cosmic strings. In our framework, FRB 121102 was investigated as first discovered repeating fast radio burst. For several groups of bursts events, it was obtained a parameter, which characterizes a possible radiation source – cosmic string loop, specifically, the energy scale of phase transition during which the string was formed |
