|Title||The X-ray Absorber of the X-ray Transint BAL NLS1 WPVS 007|
|Author||Dr Dirk Grupe|
|Description||We propose to obtain a well-exposed X-ray spectrum of the X-ray transient Narrow-Line Seyfert 1 galaxy (NLS1)-transient Broad Absorption-line AGN WPVS 007 with XMM-Newton simultaneously with our approved HST-Chandra observations. The goal is to establish a tight connection between the UV broad absorption line troughs found in FUSE observations and the strong partial covering absorber feature found by Swift. WPVSvirgul007 showed a dramatic transformation into a BAL-QSO between a 1996 HST observation and a 2003 FUSE observation; the recent Swift X-ray detections suggest that the absorber has started to disappear. Therefore it is crucial for our HST COS UV spectroscopy to know what the status of the X-ray absorber is.|

|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.
