Mid-IR spectral modelling of the nuclear regions of NGC 5506 (top panel) and NGC 5728 (bottom panel). The JWST/MRS rest-frame spectra and model fits correspond to the black and red solid lines. We show the continuum (brown solid lines) and the fitted PAH features (orange solid lines). Note that NGC 7172 does not show nuclear PAH emission and, thus, it is not included in this plot.
