|Title||A late time look at the relativistic tidal disruption event Swift 2058+0516|
|Author||Dr Andrew Levan|
|Description||In March and May this year, our collaboration discovered two examples of an apparently new class of high energy transient. Named Swift 1644+57 and Swift 2058+0516, they are exceptionally X-ray bright events, accompanied by emission across the electromagnetic spectrum. A working model is that these are the tidal disruption of a star by the central black hole in a distant galaxy, although alternative models remain plausible. Here we seek long term observations of Swift 2058+0516. Using XMM-Newton we will measure both the lightcurve and spectrum at late times while the source is too faint for the Swift-XRT. In doing so we will determine late time properties of the object (e.g. disc vs jet) and compare the lightcurve to the expectations for tidal disruption events.|

|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.
