|Title||Lifting The Shroud Around Broad Absorption Line Quasars with XMM|
|Author||Dr Smita Mathur|
|Description||We propose 40ksec observations of three X-ray detected BALQSOs for precision spectroscopy with EPIC PN. We also propose for exploratory 5ksec observations of 4 other BALQSOs. We will be able to: (1) determine column density and spectral shape accurately, (2) determine the partial covering factor and redshift of the absorber, (3) test if BALQSOs are normal quasars viewed along absorbed line-of-sight, (4) test if polarization or IR brightness is a good predictor of 2-10 keV brightness of BALQSOs. If instead BALQSOs are found to be intrinsically underluminous in X-rays, it would alter their photoionization modeling and would change the X-ray luminosity function of AGN.|

|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.
