Time- and azimuth-averaged poloidal slices of rest-mass density with averaged conserved currents overlaid for the MAD a* = +0.94 model. In the top row, we plot (left to right) the mass ﹩{{\mathfrak{J}}}_{M}\equiv \sqrt{-g}\rho {u}^{\mu }﹩, angular momentum ﹩{{\mathfrak{J}}}_{L}\equiv \sqrt{-g}{T}_{\phi }^{\mu }﹩, and energy ﹩{{\mathfrak{J}}}_{E}\equiv -\sqrt{-g}{T}_{t}^{\mu }﹩ currents. The middle row shows from left to right the total angular momentum current, the electromagnetic contribution, and the fluid contribution, respectively. The bottom row is similar to the middle row except that we plot the energy current. The arrows in the flow lines indicate the direction of the conserved currents, and the color scale indicates the magnitude plotted on a log scale since it can vary by several decades on a poloidal slice. The general morphology of the currents is similar, namely, strong inflow in the disk that transitions to an outflow at higher latitudes.
