Spitzer spectroscopy has revealed that ≃80% of submm galaxies (SMGs) are starburst (SB)-dominated in the mid-infrared. Here we focus on the remaining ≃20% that show signs of harboring powerful active galactic nuclei (AGNs). We have obtained Spitzer-InfraRed Spectrograph spectroscopy of a sample of eight SMGs that are candidates for harboring powerful AGNs on the basis of IRAC color selection (S_(8 μm)/S_(4.5 μm) > 2, i.e., likely power-law mid-infrared spectral energy distributions). SMGs with… Expand
