Cosmological zoom-in simulations find that grain-grain shattering in diffuse ISM gas drives rising PAH mass fraction with time, naturally producing the observed PAH-metallicity relation and inverse qPAH-molecular gas trends.

JWST observations of z~1.1 galaxies produce PAH ratio maps showing larger and more neutral PAHs at larger radii, opposite local trends, linked to UV hardness via photo-destruction.
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.
