Abstract | We propose to observe seven very luminous 3CR quasars, which together with analready observed one, form 4 pairs of sources, each composed by a type 1 and atype 2 object, with similar redshift and radio luminosity. These objects areexpected to be the most luminous quasars observed in the X-rays (2-10 keVintrinsic luminosity L>10^45 er/). With these observations we will be able totest whether the unified model of AGNs still holds at these luminosities in awell defined, homogeneous and representative sample of objects. We will measurethe absorption properties of these objects, checking whether Compton thicksources are common among type 2 quasars. |

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. |
