Currently envisioned extensions of the Event Horizon Telescope to space will soon target black hole photon ring: a narrow ring-shaped imprint hole's strong gravity produced in its images by highly bent trajectories. In principle, shape ring encodes information about geometry underlying spacetime. practice, however, whether or not this can be extracted from depends on several factors, ranging astrophysical details emitting source (such as magnitude plasma fluctuations) specific configuration...

General relativity predicts that black hole images ought to display a bright, thin (and as-of-yet-unresolved) ring. This "photon ring" is produced by photons explore the strong gravity of hole, flowing along trajectories experience extreme light bending within few Schwarzschild radii horizon before escaping. The shape photon ring largely insensitive precise details emission from astronomical source surrounding and therefore provides direct probe Kerr geometry its parameters. Black Hole...
