The sources are selected on the basis of bright 24um fluxes (F24um>0.4mJy) and of stellar dominated near-infrared spectral energy distributions in order to favor z∼2 starburst galaxies. The average 1.2mm flux for the whole sample is 1.5±0.2mJy. Our analysis focuses on 29 sources in the Lockman Hole field where the average 1.2mm flux (1.9±0.3mJy) is higher than in other fields (1.1±0.2mJy). The analysis of the multiwavelength spectral energy distributions indicates that these sources are starburst galaxies with far-infrared luminosities from 1012 to 1013.3L, and stellar masses of ∼0.2-6x1011M. Compared to submillimeter selected galaxies (SMGs), the SWIRE-MAMBO sources are among those with the largest 24um/1.2mm flux ratios. The origin of such large ratios is investigated by comparing the average mid-infrared spectra and the stacked far-infrared spectral energy distributions of the SWIRE-MAMBO sources and of SMGs. Description: Observations were spread over the pool observing sessions at the Institut de Radioastronomie Millimetrique (IRAM) 30m telescope in fall/winter 2005/2006, using the 117 element version of the Max Planck Millimeter Bolometer (MAMBO) array operating at a wavelength of 1.2mm (250GHz).
