| Abstract | Understanding the physical conditions under which quiescent nuclear BH areactivated during galaxies encounters is one of the most debated questions in thelast decades. Very few simultaneously active dual AGN have been detected up tonow in mergers, and most of them serendipitously. X-rays have proven to be thebest tool to detect hidden AGN and the WISE MIR color-color plots provide a gooddiagnostics tool for selecting the AGN candidates. Here, we propose tocharacterize the nuclear sources and unveil dual AGN in the best candidates of asample of IR bright galaxy mergers, which were never observed in X-rays. |

| 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. |
