| Abstract | We propose to observe for a full XMM-Newton orbit (~120 ks) the lensed quasarB 1152+199 (z = 1.019). The flux magnification will make it possible to study in detail the central regions of this quasar, where two previous Chandra snapshots (of 16 and 8 ks) suggest the presence of a broad iron line from the accretion disc and possible absorption. Such features, almost ubiquitous in the local Universe, are still elusive at moderate/high redshift due to the low data quality usually available, in spite of their important implications in terms of supermassive black hole accretion history, cosmic X-ray background, and feedback. The new spectrum will allow the detection of any emission and/or absorption line down to an equivalent width of about 100 eV. |

| 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. |
