We propose XMM-Newton observations of 3 sub-millimeter bright galaxies (SMGs)spanning z=2.1-3.6. These SMGs are gravitationally lensed by massive foregroundgalaxies, and each has an apparent luminosity >e14 Lsun, showing no sign for AGNin extensive multi-wavelength analysis. The combination of the sensitivity ofXMM- Newton and the lensing magnification, as well as the intrinsic brightnessof the SMGs, will enable us to study them individually. We will measure thecollective X- ray emission from X-ray binaries and hence its ratio to the starformation rate for the first time and to potentially detect extremely obscuredAGN over the rest-frame 2-35 keV range. This study will represent a key step inour multi- wavelength campaign to understand the working of such extreme galaxies.

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.
