| Abstract | A 70 ks observation of the Seyfert 2 galaxy NGC 5252, to be performed both by XMM-Newton and Chandra, is requested. X-ray observation of Seyfert galaxies havehighlighted that 40% of these objects show extended emission probably due to anoutflowing gas. We choose NGC 5252 to test this scenario. for its remarkableoptical ionization cones. Goal of this proposal is to disentangle the followingissues: 1)to firmly demonstrate that the diffuse emission is due to an AGNdriven outflow; 2)to understand if the outflowing gas is confined by gravity;3)to study the past history of the AGN activity; 4)to observe the shadow of thedusty torus. Even if only one of the above mentioned point is achieved, thiswould represent a significant step in the comprehension of AGN. |

| 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. |
