Images of a geometrically thick accretion disk with inner radius r_in = 2.91M in a Kerr spacetime with spin a = 0.8M (left column), or in a Lamy wormhole spacetime with spin a = 0.8M and charge b = M. The inner disk radius is at r_in = 2.91M for the left and right panels, and at r_in = 1.6M for the central panel. As in all figures, the bottom row corresponds to the top row images blurred to the EHT resolution of 20 μas, the dashed blue circle has a diameter of 40 μas (size of the ring feature reported by the EHT), and the blue arrow shows the projected direction of the approaching jet.
