Photon Ring Autocorrelations

Hadar, Shahar, Johnson, Michael D., Lupsasca, Alexandru et al.

Understand

In the presence of a black hole, light sources connect to observers along multiple paths.

As a result, observed brightness fluctuations must be correlated across different times and positions in black hole images.
Photons that execute multiple orbits around the black hole appear near a critical curve in the observer sky, giving rise to the photon ring.
In this paper, a novel observable is proposed: the two-point correlation function of intensity fluctuations on the photon ring.
