Southern radio lobe and hotspot S2 of NGC 7319. First row, from left to right: [Ne II]12.81 μm, [Ne III]15.56 μm, [Ne V]14.32 μm, and H₂ S(2) 12.28 μm MIRI MRS line maps. The contours on the first panel represent the 1.4 GHz emission for reference, as in Fig. 1. The dashed circle on the [Ne II] map is the S2 extraction aperture. The red hatched circles represent the PSF FWHM, ∼049–056. Second row: The first three panels are the same as the last-row panels of Fig 2. The fourth panel is the velocity dispersion of the [Ne III]15.56 μm emission line.
