Deep cosmological surveys at infrared and submillimeter wavelengths have revealed a population of sources with very high star formation rates (SFR 2000 Msol/year) at z 2. These sources would form sim 10^{11} M_{odot} in only sim 5 imes10^7years! If these sources are really dominated by star formation with a such a high SFR, they are an enigma for the coevolution of the mass spheroid and SMBH since no traces of AGNs have been found in them, even though they are forming a large amount of their mass into stars. One possibility is that an AGN is contributing significantly to their IR emission. Another possibility is that they exhibit different MIR-FIR properties than local sources, which could lead to an overestimation of their estimated SFR. We propose to take high quality Spitzer IRS spectra to probe the MIR properties of these sources. We have selected targets from fields with very deep FIR data so we can understand the nature of the sources across the infrared regime.
