Equatorial photon trajectories launched from the AD material orbiting a clockwise-rotating BH with increasing dimensionless angular momentum, j (from left to right). We see the event horizon (central black disk), the ergosphere (gray annulus), the photon ring (inner cyan solid line circle), and the AD (outer thick yellow annulus) from r_inner = r_ISCO to r_outer = 2 r_ISCO. The photons were launched at angles measured from the outward radial direction at 80° (dot-dashed green), 90° (dotted red), 120° (solid blue), and 160° (dashed purple). We notice that as the BH spin increases, the photon trajectories that reach the observer at the bottom (green disk) get dragged along by the spacetime rotation.
