Figure 7

Movie snapshots from Scene 1. The simulation time (in units of \(r_{\mathrm { g}}/c\)) is shown in the upper-left corner of all panels. From top to bottom: Scene 1 begins at frame 1600, where accretion onto the black hole has not yet begun, which can be seen as the faint, stationary equilibrium accretion torus configuration in the centre of the image. By frame 2300 accretion has begun (see also Fig. 8) and the dim jet (upper half of image) and dimmer counter jet (lower half of image) propagate outwards through the ambient medium. At frame 3000 the jet has propagated further outwards, and angular momentum transport has shifted torus material outward, as can be seen by the increased angular size of the inner accretion flow. The black hole shadow is not visible since the accretion rate has yet to reach a quasi-stationary state
