| Description | We propose a new XMM-Newton monitoring of the X-ray obscured AGN in NGCvirgul4507, with the aim of testing a scenario where the variable X-ray absorption is due to the broad emission line clouds. The identification of these two components is suggested by our previous monitoring of a few other sources (NGC 1365, NGC 4151, UGC 4203), where rapid X-ray absorption variability, suggestive of an extremely compact X-ray absorber, has been found ..by chance. The new campaign we propose is for the first time based on a precise prediction, rather than on a blind search, and will therefore provide a strong test of the general validity of this new scheme for the structure of the AGN circumnuclear medium. |

| 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. |
