Abstract
Imaging of NGC 7469 in the J, H, & K bands shows that the starburst 'ring' is a tight inner spiral with arms that extend 4″ NW and SE from the nucleus, as well as distinct infrared hotspots associated with the radio continuum sources. Imaging in the 3.28 µm dust emission feature shows extended PAH emission that is roughly aligned with published 12.5 µm continuum emission (PA~75°), consistent with small dust grains heated by vigorous star formation in the inner spiral.
