Spatially resolved [O III]λ5007 emission-line maps for TN J1338. Left: [O III] moment 0 (integrated flux) map with green contours tracing the [O III] flux and the magenta contours displaying the radio continuum levels from the VLA 4.5 GHz image (L. Pentericci et al. 2000). A significant concentration of ionized gas is observed offset from the center, near the lobe. Middle: [O III] W80 map tracing the line width, revealing localized broadening exceeding 2000 km s−1 in the vicinity of the northern radio lobe. As discussed in N. Roy et al. (2024), these broad profiles indicate strong outflows and enhanced turbulence driven by jet-ambient medium interactions near the bow shock. Right: radial profile of W80 along the jet axis, showing a ∼3× increase in line widths near the radio lobe, consistent with large-scale, lobe-associated outflows. Bottom-left, middle, and right panels show the resolved map of gas mass, radial profiles of mass outflow rates, and kinetic energy outflow rates, respectively.
