BH courtyard. Left panel: Temperature [log10(K)] and velocities (arrows, white to red) in a slice normal to the orbital plane and through BH (at x = 0, y = 0) and accretion cone. Visible are the cocoon (bow shock flow, green, on the left), the atmosphere (red and yellow, above and below the BH), the disk (dark blue), and the accretion cone (dark blue) with engulfing shock (green and yellow, on the right). Middle panel: Disk feeding region in orbital plane, density [log10(g/cm³)] and velocities (arrows, blue to white). The BH moves in the direction of the pink arrow. Right panel, top: Time-dependent mass flow to the BH (in 10⁻⁸ M_⊙/yr, time mean in blue), integrated over the accretion cone at 2 × 10¹¹ cm from the BH (black line in bottom right panel). Right panel, bottom: Density [log10(g/cm³] and velocities (same coloring as middle panel, same slicing plane as left panel). Lengths are in units of 10⁹ cm. Velocities are in the frame co-orbiting with the BH, projected onto the slice shown, in 10⁸ cm/s.
