| Abstract | Motivated by the detection of a relativistic outflow of highly ionized gas in aprevious XMM-Newton observation of the lensed quasar APM08279+5255, we proposefour 90ks observations of this object to improve our understanding of thesignificance of such outflows in regulating black hole growth and in influencingstructure formation. The large lensing magnification of about 100 makesAPM08279+5255 the only quasar for which we can presently constrain theproperties of the outflow just before the peak of the number density of luminousquasars. Our main scientific goals are: (a) verify the present interpretationsof the Fe absorption lines, (b) monitor the time variability of the Fe lines,and (c) constrain the kinematic, ionization and absorbing properties of the quasar outflow in APM08279+5255. |

| 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. |
