Interferometric signature of higher-order images in a parametrized framework
Fabiano Feleppa, Fabio Aratore, Valerio Bozza
This paper investigates gravitational lensing in the strong deflection limit, focusing particularly on higher-order images produced near compact objects such as black holes and the…
Gravitational lensing by extremal rotating black holes in the strong deflection limit
Fabiano Feleppa, Valerio Bozza, Welmoed Marit de Graaf
In the strong deflection regime, light rays passing close to an astrophysical black hole may remain trapped near unstable photon orbits for a long time before escaping to infinity.…
Strong deflection limit analysis of black hole lensing in inhomogeneous plasma
Fabiano Feleppa, Valerio Bozza, Oleg Yu. Tsupko
This paper investigates gravitational lensing effects in the presence of plasma in the strong deflection limit, which corresponds to light rays circling around a compact object and…
Strong deflection of massive particles in spherically symmetric spacetimes
Fabiano Feleppa, Valerio Bozza, Oleg Yu. Tsupko
Near a gravitating compact object, massive particles traveling along timelike geodesics are gravitationally deflected similarly to light. In this paper, we study the deflection ang…
