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.
