Description
While static axis-symmetric solutions of gravitating cosmic strings have been found numerically, dynamical solutions are much harder propositions and little has been done in this aspect. We developed a solver for local U(1) together with Einstein field equations. Using the solutions of strings with perturbations from Vachaspati and Garfinkle, we find initial data for our string and construct dynamical solutions of gravitating cosmic string in numerical relativity. This will allow us to investigate various physical scenarios like the collision of wave-trains.
