The coalescence of binary supermassive black holes (SMBH) in galaxy mergers isthought to constitute the strongest source of gravitational waves. Theorysuggests these waves carry momentum causing the merged black hole to experiencea velocity recoil or kick that displaces or indeed ejects it from the center ofits host galaxy. We request the fi rst XMM-Newton and HST imaging ofRXJ1756.4+5235, a source with an o ffset broad line point source that is offsetfrom the nucleus of a nearby galaxy to resolve whether the source is a potentialrecoiling black hole or a close dual 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.
