Ghost images in Bardeen and ABG spacetimes
Original language description
We present our study of bending of null geodesics in the regular spacetimes, particularly in Bardeen and Ayon-Beato-Garcia (ABG) no-horizon spacetimes. We show that thanks to “flatness” of these spacetimes in the central region there exist interesting optical phenomena related to photons with small impact parameters traveling through such gravitational field . There exist a critical impact parameter which gives maximal deflection of light in the Bardeen and ABG no-horizon spacetimes. We discuss “ghost” direct and indirect images of Keplerian discs which are generated by photons with small impact parameters and to the classical scattering cross section in such regular but strongly curved spacetimes.
