Temperature snapshots of the runs with BH spin a_* = 0.9. From left to right, the Bondi radius R_B (shown as gray dotted circles) increases, or equivalently, the asymptotic gas temperature T_∞ decreases. The horizontal bars in the left bottom corner of each panel show scales in gravitational units r_g, while the bars in the right bottom corner show scales in physical units (parsecs) assuming the M87 BH mass.
