Title XMM Spectroscopy of the X-ray Detected Broad Absorption Line QSO CSO 755

Author Prof William Brandt
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.
