Spatial Correlations of PAH, UV, H$\alpha$ Emission and IMF - PAH Variations in the Star-Forming Complexes of NGC 628
In NGC 628 SFCs, PAH luminosities track UV/Hα, and PAH band ratios increase toward top-heavy, bluer complexes, with flatter spur trends and shell-vs-shear IMF differences near the phantom void.
