| Description | Motivated by the detection of a relativistic outflow of highly ionized gas in a previous XMM-Newton observation of the lensed quasar APM08279+5255, we propose four 90ks observations of this object to improve our understanding of the significance of such outflows in regulating black hole growth and in influencing structure formation. The large lensing magnification of about 100 makes APM08279+5255 the only quasar for which we can presently constrain the properties of the outflow just before the peak of the number density of luminous quasars. Our main scientific goals are: (a) verify the present interpretations of 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 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. |
