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…
Overlapping of photon rings in black hole imaging
Oleg Yu. Tsupko, Fabio Aratore, Volker Perlick
In this paper, we investigate the overlapping of photon rings - higher-order images of a black hole's luminous environment, concentrated near the shadow boundary and expected to be…
Light deflection in axially symmetric stationary spacetimes filled with a moving medium
Christian Pfeifer, Barbora BezdÄková, Oleg Yu. Tsupko
The deflection of light rays near gravitating objects can be influenced not only by gravity itself but also by the surrounding medium. Analytical studies of such effects are possib…
