JWST observations find constant ~1% PAH abundance in the M82 superwind to 5 kpc, consistent with shielding in surface layers of cool clouds and possible replenishment.

Aliphatic side chains on PAHs shift certain infrared band intensity ratios, especially in small molecules, which can mislead ionization-state estimates, though the main diagnostic grid still applies with possible calibration.
Rest-frame 6-8um MIRI luminosity provides broken power-law SFR calibrations with 0.2-0.3 dex scatter and UV+IR composites at 0.15 dex, supporting robust use above log M* ~9 up to z~3.
