Abstract PHANGS–JWST mid-infrared (MIR) imaging of nearby spiral galaxies has revealed ubiquitous filaments dust emission in intricate detail. We present a pilot study to systematically map the filament network (DFN) at multiple scales between 25 and 400 pc NGC 628. MIRI images 7.7, 10, 11.3, 21 μ m 628 are used generate maps emission, while PHANGS–HST B -band yields attenuation features. quantify correspondence traced by MIR thermal continuum/polycyclic aromatic hydrocarbon (PAH) detected...
