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…
