Deposit of particle kinetic energy on the disk. Left panel: flux on the disk of particle kinetic energy per unit time per ring of infinitesimal width, dr, as a function of the distance, r, to the BH, for a = 0.8. The solid blue curve is the median profile, and the light blue shaded region is the 1σ variability. Vertical lines are the event horizon (solid) and the separatrix footpoint (dashed). Right panel: flux of particle kinetic energy per unit time near the separatrix footpoint compared to the rate of energy deposited onto the disk, Ė_BH−disk, per unit time via the coupling magnetic field lines.
