Description | Various observational evidences suggest that the obscuration of AGNs increases in the presence of non-axisimmetric potentials, due to the capability of the latter to drive gas into the nuclear region. In particular, Seyfert 2s hosted in barred galaxies are generally Compton thick. We propose to extend this study to tightly interacting/merging Seyfert 2 galaxies by observing a sample of this class of objects with XMM. We expect interacting/merging Seyfert 2s to be on average obscured by a much larger column of gas than isolated, dynamically relaxed Seyfert 2s. Since galaxy interactions are more frequent at higher redshift, this study would have important implications on the origin of the (hard) X-ray background. |

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. |
