Gravitational and Particle Radiation from Cosmic Strings
Anzhong Wang, Nilton O. Santos
Abstract
Gravitational and massless particle radiation of straight cosmic strings with finite thickness is studied analytically. It is found that the non-linear interaction of the radiation fields emitted by a cosmic string with the ones of the string always makes the spacetime singular at the symmetry axis. The singularity is not removable and is a scalar one.
