Figure 5From: Observing supermassive black holes in virtual realityUsed tracer-particle trajectory and it’s corresponing velocity. Left panel: the trajectory of the tracer particle that is used to initialise the camera trajectory. Right panel: the velocity profile of the tracer particle. The velocity peaks when the particle is closest to the black hole, where the angular velocity is high. The time shown on the x-axis is the time range of the frames used for Scene 3Back to article page
