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…

Scalar perturbations in deflationary cosmological models
S. Capozziello, G. Lambiase, G. Scarpetta
We consider scalar perturbations of energy--density for a class of cosmological models where an early phase of accelerated expansion evolves, without any fine--tuning for graceful…
