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…

Spin-2 particles in gravitational fields
G. Papini
We give a solution of the wave equation for massless, or massive spin-2 particles propagating in a gravitational background. The solution is covariant, gauge-invariant and exact to…
