JWST/MRS spatially resolved maps. From left to right panels: NGC 5506, NCG 5728, and NGC 7172. Top panels: Hardness of the radiation field maps traced by the [Ne III]/[Ne II] ratios. The colour-coded contours correspond to the average [Ne III]/[Ne II] ratios found in QSO (black line), Sy1 (blue line), Sy2 (red line), LINER (green line), and H II (magenta line) regions reported in Pereira-Santaella et al. (2010). Bottom panels: 11.3/6.2 PAH ratio maps. Dark green contours correspond to the 11.3 μm PAH emission. The first contour is at 3σ and the last contour at 1.5 × 10⁻¹⁵ erg s⁻¹ cm⁻². Colour-coded circles correspond to the nuclear PAH ratios. The central regions correspond to the 11.3/6.2 PAH ratios measured in the nuclear spectra. For NGC 7172, the black circle represent the non-detection of nuclear PAH for this source (see Sect. 5.1 for further details). North is up and east is to the left, and offsets are measured relative to the AGN.
