|Title||In search of merging black holes|

|Description||Merging AGN pairs in interacting galaxies provide a rich laboratory for studying triggering of AGN activity and its evolution, starbursts, merging black holes, and the black-hole galaxy co-evolution. We propose to search for such AGN pairs in a carefully chosen sample of interacting galaxies. Our observing strategy is based on the analysis of successes and failures of previous such efforts. The hard X-ray response of XMM-Newton is important in unveiling these buried AGNs and disentangling the starburst component. We request exploratory observations of four targets and a long observation for precision spectroscopy of one target in which hard point sources were detected with Chandra. Thus the proposed program has a component of guaranteed scientific return and one of discovery space.|

|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.
