|Title||A multi-wavelength assessment of the role of galaxy mergers in AGN triggering.|
|Author||Prof Sara Ellison|
|Description||n order to understand the hotly debated role of galaxy mergers in the triggering of nuclear activity it is necessary to obtain a complete multi-wavelength census of AGN, regardless of their dominance over the host galaxy, dust obscuration and line of sight absorption. Our team has previously assessed the optical, mid-IR and radio AGN properties of a sample of virgul100 post-merger galaxies - but the complete picture now requires the X-ray classifications to complete the AGN census. Specifically, the observations proposed here we allow us to compute the fraction of X-ray AGN, which can be compared to the fraction inferred from optical, radio and mid-IR diagnostics and also infer the Compton thick fraction, compared to a sample of control galaxies in the public S82X sample.|

|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.
