|Title||Compact binary mergers: SGRBs, r-process kilonovae & gravitational-wave sources|
|Author||Prof Nial Tanvir|
|Description||Merging compact binaries are widely thought to produce short-GRBs and are also the most promising targets for the new gravitational wave detectors. Recently we found evidence for an r-process kilonova accompanying a SGRB, which both confirms the compact binary model, and provides an alternative, unbeamed EM signal of GW events. It also opens a route to estimating the yield of such events and hence their contribution to global heavy element production. Understanding the range of KN behaviour requires deep, multiwavelength followup of future events. X-ray observations are key to quantifying the contributions of relativistic jet emission and later time engine activity (accretion or magnetar spin-down), and distinguishing mergers from unrelated interlopers amongst GW counterpart candidates.|

|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.
