Probing Kerr spacetime via interferometric signatures of higher-order images
Fabiano Feleppa, Fabio Aratore, Valerio Bozza +1
Higher-order images produced by photons that orbit close to the unstable photon region of a black hole encode information about the spacetime geometry and leave characteristic sign…
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.…
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…
Decoding a black hole metric from the interferometric pattern of the relativistic images of a compact source
F. Aratore, V. Bozza
Photons emitted by light sources in the neighbourhood of a black hole can wind several times around it before fleeing towards the observer. For spherically symmetric black holes, t…
Relativistic iron lines in accretion disks: the contribution of higher order images in the strong deflection limit
G. F. Aldi, V. Bozza
The shapes of relativistic iron lines observed in spectra of candidate black holes carry the signatures of the strong gravitational fields in which the accretion disks lie. These l…
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,…
