| Description | We propose to observe seven very luminous 3CR quasars, which together with an already observed one, form 4 pairs of sources, each composed by a type 1 and a type 2 object, with similar redshift and radio luminosity. These objects are expected to be the most luminous quasars observed in the X-rays (2-10 keV intrinsic luminosity L>10^45 er-). With these observations we will be able to test whether the unified model of AGNs still holds at these luminosities in a well defined, homogeneous and representative sample of objects. We will measure the absorption properties of these objects, checking whether Compton thick sources are common among type 2 quasars. |

| 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. |
