Radiative non-Abelian cosmic strings with negative cosmological constant

We investigated the SU(2) Einstein-Yang-Mills system with a cosmological constant on a time-dependent non-diagonal cylindrical symmetric spacetime. Only for suitable negative Λ and specific initial values, we find numerically regular wave-like solutions dressed with both electric and magnetic charges. The cosmic string feature is maintained by the finite angle deficit the solutions possess. In general the solution will develop a cosmological horizon; however, it resolves for increasing negative values of the cosmological constant and increasing time. Further, the features of the dyon depend on the angular momentum flux
