Ghost Images in Bardeen and ABG spacetimes |
|
Abstract |
In this contribution 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 traveling through such gravitational field with small impact parameters. There exist a critical impact parameter which gives maximal deflection of light in Bardeen no-horizon spacetimes. We discuss "ghost" direct and indirect images of Keplerian discs which are generated by photons with small impact parameters. |
