| Description | 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 virgul50% 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. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
