VizieR Online Data Catalog: z=1-3 ULIRGs from the Spitzer SWIRE survey (Berta+, 2007)

We present Keck/LRIS optical spectroscopy of 35 z>=1.4 luminous IR galaxies in the Spitzer Wide-area Infra-Red Extragalactic survey (SWIRE) northern fields (Lockman Hole, ELAIS-N1, ELAIS-N2). The primary targets belong to the "IR-peak" class of galaxies, having the 1.6{mu}m (restframe) stellar feature detected in the IRAC Spitzer channels. The spectral energy distributions of the main targets are thoroughly analyzed, by means of spectro-photometric synthesis and multi-component fits (stars + starburst dust + AGN torus).

Observations were carried out in multi-object mode with the Low Resolution Imaging Spectrometer (LRIS) at the Cassegrain focus of the Keck-I telescope, during the nights of May 27th and 28th, 2006.
