We request a total of 123 ks of EPIC data to observe four local ULIRGs that arePriority A NuSTAR targets. The XMM data will help determine whether the X-rayweak nature of these sources is due to intrinsically weak or highly absorbedAGNs. With NuSTAR, we can reach to unprecedented sensitivities at above 10 keV.Contemporaneous XMM coverage is essential to place constraints on the columndensities and the intrinsic AGN luminosities of these highly absorbed, compositeobjects and to pinpoint the origin of the variability below 10 keV seen in thesesources. Our NuSTAR program will contextualize the AGN contribution to localULIRGs, which will bear on results obtained at other wavelengths on thecosmological significance of ULIRGs to galaxy evolution and black hole growth.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
