Narrowband channel maps of [O III]λ5007 emission in 4C+19.71, constructed along wavelength slices from the blue to red side of the emission line, similar to Figure 7. The slices span a total velocity range of ∼1430 km s⁻¹. The ionized gas morphology is initially compact and concentrated near the radio core, but becomes increasingly extended in subsequent velocity slices, revealing a faint, bent bridge of emission connecting the central region to the northern radio lobe across ∼30 kpc. The northern lobe is located near the edge of the NIRSpec IFU field of view. The kinematically varying nebular structure and the evolving [O III] emission morphology across velocity channels suggest disturbed, complex, multicomponent ionized gas that extends preferentially along the radio axis.
