Abstract Energetic AGN outflows that absorb X-ray and UV radiation are common, yet theirproperties remain poorly understood. We propose to complete the X-rayspectroscopic coverage of a well-defined sample of 13 PG AGN that appear to bestrongly absorbed by their outflows. We will determine their X-ray absorptionand continuum properties, providing the first general conclusions about (1) theorigin of soft X-ray weakness in AGN, (2) the X-ray/UV absorption connectionranging from associated UV absorbers to BALs, (3) the column density, ionizationparameter, and covering fraction of the X-ray absorbing material, and (4) therelation of the X-ray absorption properties to other key AGN properties. Oursample has the best supporting multiwavelength data available.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
