Photon trajectories in the Kerr-like wormhole space-time with a = 0.998, λ = 0.9 for an observer at θ0 = 80°. Each trajectory is uniquely determined by its initial coordinates (α, β) on the observer’s celestial plane. The trajectories contains rays that are deflected around the object as well as rays that approach (and may traverse) the throat, demonstrating the nontrivial light propagation in the wormhole geometry. The resulting trajectories are shown in 3D Cartesian coordinates in units of GM/c2.
