Effective null geodesics and black hole images in Kruglov nonlinear electrodynamics
In Kruglov nonlinear electrodynamics, small positive values of the parameter q produce stable photon orbits outside the event horizon and modify black hole shadows and relativistic images even when the spacetime metric stays close to Reissner-Nordström.
