|Title||BROAD ABSORPTION LINE QUASARS|
|Author||Prof RICHARD GRIFFITHS|
|Description||GT - The targeted objects are selected from a list of BAL QSOs which are known to be weak in soft x-rays but which are good candidates for having strong emission at higher energies. The main aims of the program are to: (i) determine their x-ray properties up to 10 keV in order to show whether they are absorbed or altogether weak and (ii) to determine whether they are suitable for follow-up XMM observations. Mass-ejecting BAL QSOs comprise 10% of the total QSO population and these observations will put important constraints on the underlying mechanisms.|

|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.
