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…
Spectroscopic Constraints on the Mid-Infrared Attenuation Curve: I -- Attenuation Model using PAH Emission
Thomas S. -Y. Lai, J. D. T. Smith, Els Peeters +4
We introduce a novel model to spectroscopically constrain the mid-infrared (MIR) extinction/attenuation curve from 3--17 um, using Polycyclic Aromatic Hydrocarbon (PAH) emission dr…
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…
