Abstract

We present the results of IRS low-resolution spectroscopy of 51 Seyfert galaxies, part of a large Spitzer observing program to determine the mid-to-far infrared spectral energy distributions of a well-defined sample of 87 nearby, 12 mu m-selected Seyferts. We find that the spectra clearly divide into groups based on their continuum shapes and spectral features. The infrared spectral types appear to be related to the Seyfert types. Some features are clearly related to a starburst contribution to the IR spectrum, while the observed power-law continuum shapes, attributed to the AGN, may be dust or non-thermal emission. Principal component analysis results suggest that the relative contribution of starburst emission is the dominant cause of variance in the spectra. We find that the Sy 2's show on average stronger starburst contributions than the Sy 1's.
