| Abstract | High luminosity quasars are unique laboratories to test our understanding ofX-ray coronae in AGN. We propose joint XMM-Newton and NuSTAR observations of aluminous, optically-selected, non-jetted quasar at z=0.821. Our main goal is tomeasure the high-energy cutoff in its X-ray spectrum, hence constraining, in theframework of Comptonization models, its coronal temperature and optical depth. This will allow us to test whether the same physical conditions hold in quasarsat luminosities and masses 100 times higher than those probed in so far in thenearby Universe, exploring the unknown X-ray properties of the quasar populationat intermediate redshifts (z = 0.1-1), constituting half the age of theUniverse. |

| 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. |
