Scientific paper

We propose to observe a small group of four Ultraluminous Infrared Galaxies optically classified as starbursts, which according to our analysis based on Spitzer 5-8 micron spectra hide obscured active nuclei. These AGNs probably account for ~50% of the total source luminosity, which puts them among the few known QSO2s al low redshift (z<0.25). The XMM-Newton observations will test our prediction, possibly providing a direct evidence of these hidden nuclei. While it is well assessed that most of the luminosity of local ULIRGs is due to starbursts, our observations would further increase the fraction of these objects known to host an AGN.
