Abstract |
Black holes represent the ideal laboratory to observe the deflection of light rays. We focus our attention on the photons that perform large deflection angles, winding several times around the black hole before reaching the observer. Here, we show the analytical resolution of the geodesic equations in the context of the strong deflection limit, in order to obtain the photons path in presence of a rotating black hole. Subsequently, we shall point out how the strongly deflected photons can affect the observables in some astrophysical applications. |
