|Title||XMM and HST Target of Opportunity Observations of Tidal Disruption Events|
|Author||Prof Andrew Levan|
|Description||Tidal disruption events (TDEs), where a star is disrupted while passing close to a black hole, enable a view of accretion onto supermassive objects from quiescence to super-Eddington rates, on a timescale of a few years. Here we propose to characterise the spectral and temporal properties two TDEs found in AO15. As part of a comprehensive multiwavelength campaign we will use XMM-Newton and HST to map either side of the expected hot black-body peak; search for evidence of non-thermal components; track the cooling of the event and study the long and short timescale variability of the sources. In doing so we will create exquisite, panchromatic pictures of these extreme 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.
