The WISE All-Sky Survey unveiled a population of extremely red, dust-enshroudedgalaxies, the so-called W1W2-dropout galaxies. Growing evidence indicates thatthey represent a very rare population of high-z hyper-luminous (virgul10^(14) Lsun),heavily obscured QSOs.We propose here to obtain the first X-ray observations oftwo exceptional W1W2-dropout QSOs at zvirgul3 that, thanks to their opticalbroad-line classification, challenges this scenario. The clear view toward thecentral engine indeed offers the unique opportunity to accurately measure theX-ray luminosity of these extreme objects undergoing the transition from buriedto optically bright QSOs. Probing the nuclear properties of W1W2-dropout quasarscan clearly benefit our understanding of the AGN-galaxy co-evolution process.

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.
