Description We propose to observe four hyper-luminous (L_IR > 10^14 Lsun), dust-reddened, type 1 quasars at z=2-3.5, recently discovered in the wide-area UKIDSS and WISE surveys. We will constrain their X-ray luminosity and, through available multiwavelength data, accurately model their SED disentangling the disk and corona contribution to such extreme bolometric luminosities.

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.
