  Propagation and dynamics of electromagnetic vortex solitons have been studied
in the electron positron ion plasmas of super-Eddington active galactic nuclei
(AGN). Existence and stability of such structures is demonstrated for highly
transparent AGN plasma media. Possible implications of dynamical features and
corresponding observational signatures are discussed.
