Images of a thick disk surrounding a nonrotating (a = 0) black hole. The top row shows the simulated ray-traced image and the bottom row consists of the upper row images blurred to the EHT resolution (about 20 μas). The dashed blue circle shown in the lower row images has a diameter of 40 μas, consistent with the estimated diameter of the ring feature in the M87* image, reported by the EHT. This diameter translates to 11.05M in mass units of distance. The blue arrow shows the projected direction of the jet. The disk inner radius is 6M for the left panel (corresponding to the ISCO) and 2M for the two other panels (corresponding to the event horizon). The azimuthal velocity below ISCO is paramterized by v^φ = 1 (purely azimuthal velocity) for the middle panel and v^φ = 0 (purely radial plunge) for the right panel. The inner electron number density is equal to 5  ×  10⁵ cm⁻³ when r_in = 2M and 5.5  ×  10⁴ cm⁻³ when r_in = 6M (see text for details on how these numbers are chosen).
