Description
We present a catalog of mid-infrared (MIR) spectra of 150 infrared (IR) luminous galaxies in the Spitzer extragalactic first look survey obtained with the IR spectrograph on board the Spitzer Space Telescope. The sample is selected to be brighter than ~0.9mJy at 24um and it has a redshift distribution in the range [0.3, 3.5], with a peak at z=1. It primarily comprises ultraluminous IR galaxies (ULIRGs) at z>~1 and luminous IR galaxies at z<1, as estimated from their monochromatic rest-frame 14um luminosities. The number of sources with spectra that are dominated by an active galactic nucleus (AGN) continuum is 49, while 39 sources have strong, star formation related features.
