This assumes that the observed PAH features are excited predominantly by SF. With current ground-based telescopes and the upcoming JWST, much smaller spatial scales can be probed and we aim at testing this assumption in the range of few tens to few hundreds of pc. For that, we spatially map the emitted 11.3{\\mu}m PAH surface flux as a function of distance from 0.4-4 arcsec from the centre","authors_text":"A. Alonso-Herrero, A. Smette, D. Asmus, J. J.
