|Title||VIEWS OF QUASAR OUTFLOWS THROUGH NATURAL LENSES|
|Author||Dr GEORGE CHARTAS|
|Description||A recent XMM-Newton observation of BALQSO PG1115+080(z=1.72) has detected strong absorption lines in the Fe line region. A comparison between this and an earlier Chandra observation of PG1115+080 separated by 19virgulweeks resulted in a weak constraint on the variability of these absorption lines due to the low S-N of the Chandra spectrum.The proposed XMM-Newton observations will allow us to (a) monitor the variability of the Fe lines,(b) test the correctness of the present interpretation of these lines,and (c) constrain the kinematic,ionization and absorbing properties of the quasar outflow.These constraints will allow us to determine the contribution of outflows to the enrichment of the IGM,and provide insights of the connection between black hole and bulge growth in the host galaxy.|

|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.
