The Metallicity Dependence of PAH Emission in Galaxies I: Insights from Deep Radial Spitzer Spectroscopy

Cory M. Whitcomb, J. -D. T. Smith, Karin Sandstrom +9

We use deep Spitzer mid-infrared spectroscopic maps of radial strips across three nearby galaxies with well-studied metallicity gradients (M101, NGC 628, and NGC 2403) to explore t…

The Impact of an AGN on PAH Emission in Galaxies: the Case of Ring Galaxy NGC 4138

G. P. Donnelly, J. D. T. Smith, B. T. Draine +5

We present a focused study of radially-resolved varying PAH emission in the low-luminosity AGN-host NGC 4138 using deep Spitzer/IRS spectral maps. Using new model PAH spectra, we i…
