Optical caustics of Kerr spacetime: the full structure
V. Bozza
We present an exhaustive numerical investigation of the optical caustics in gravitational lensing by a spinning black hole for an observer at infinity. Besides the primary caustic,…

Strong deflection limit of black hole gravitational lensing with arbitrary source distances
V. Bozza, G. Scarpetta
The gravitational field of supermassive black holes is able to strongly bend light rays emitted by nearby sources. When the deflection angle exceeds , gravitational lensing can…
