| Description | Broad Absorption Line (BAL) QSOs allow us to observe substantial gas outflows that are probably present in most QSOs, but the geometry of their nuclear regions remains poorly understood. X-ray studies of BALQSOs suggest large amounts of X-ray absorption, and there is evidence that the X-rays we do detect are often scattered by an ionized nuclear .mirror. We propose an XMM spectroscopicobservation of CSO 755, a BALQSO we detected with SAX, to determine the geometry of its nuclear region, the shape of its intrinsic X-ray continuum, and the properties of its X-ray absorbing gas. CSO 755 is at an optimal redshift for iron K line studies which should directly reveal the scattering .mirror. and any torus. We will obtain UV and optical spectra using the OM grism |

| 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. |
