The IRS provides Spitzer with high-sensitivity low and medium resolution spectroscopy over the range of 5.5 to 37 um. The IRS is working very well, and it has greatly extended the sensitivity of mid-infrared spectroscopy. Typical results will be presented to demonstrate the capabilities of the IRS. One of these will be the IRS spectrum of SBS 0335-052, a blue compact dwarf galaxy (BCD) with one of the lowest known metallicities, ˜0.025 solar. The IRS spectrum clearly detects the silicate absorption features and puts strong upper limits on PAH emission bands. The high signal-to-noise low-resolution spectrum (R ˜90) will be compared to spectra of the prototypical starburst nucleus NGC 7714 and the prototypical Seyfert 1 nucleus NGC 4151. SBS 0335-052 is quite unlike normal starburst galaxies, which show strong PAH bands, low-ionization emission lines, and a continuum peak near 100 um. Model fits to the observed spectrum will be presented. The IRS was a collaborative venture between Cornell University and Ball Aerospace Corporation funded by NASA through the Jet Propulsion Laboratory and the Ames Research Center. This work is based (in part) on observations made with the Spitzer SpaceTelescope, which is operated by the Jet Propulsion Laboratory, California Institute of Technology under NASA contract 1407. Support for this work was provided by NASA through Contract Number 1257184 issued by JPL/Caltech.
