| Description | The WISE All-Sky Survey unveiled a population of extremely red, dust-enshrouded galaxies, the so-called W1W2-dropout galaxies. Growing evidence indicates that they 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 of two exceptional W1W2-dropout QSOs at zvirgul3 that, thanks to their optical broad-line classification, challenges this scenario. The clear view toward the central engine indeed offers the unique opportunity to accurately measure the X-ray luminosity of these extreme objects undergoing the transition from buried to optically bright QSOs. Probing the nuclear properties of W1W2-dropout quasars can clearly benefit our understanding of the AGN-galaxy co-evolution process. |

| 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. |
