| contents | We investigate the gravitational lensing properties and the formation of relativistic images associated with black holes modeled by the Reissner-Nordström and Kerr space-time geometries. In particular, we perform numerical computations of the deflection angles, image angular positions, magnification factors (including demagnification), and time delays between distinct images, and we systematically quantify the dependence of these observables on the electric charge and spin parameters of the black hole. |
