Modeling of the ionized gas outflow in M 87. Left panel: residual (after subtracting the HBH i25 model for the nuclear disk) [N II] velocity map. We emphasize the gradients in the blue- and redshifted velocities to the northeast and south. Middle and right panels: models of a filled conical outflow made with KinMSpy, with each cone shown separately. The cone half-opening angles are 45° (approaching; middle panel) and 30° (receding; right panel). Each cone has an extent of 3″ along its axis, and the radial outflow velocity within each cone is 400 km s⁻¹. The inclination of both cone axes to the LOS is 18°. The green line shows the projection of the cone axes on the plane of the sky; these project to PA 288°, the PA of the jet axis. The dotted orange lines delineate the projected shape of a disk perpendicular to the cone axes.
