|Title||Early Phase Coverage of X-ray Flares Associated with Tidal Disruption Events|
|Author||Dr Wenfei Yu|
|Description||X-ray spectral lines are expected at the beginning of the X-ray flares associated with tidal disruption events (TDE), providing great opportunity to probe the spin of dormant supermassive black holes (SMBHs) as well as detect Bardeen-Petterson (BP) effect. Little is known about the early phase of TDEs observationally. Coverage of the early phase will shed light on accretion physics under extreme conditions inaccessible in other systems. We propose an intensive coverage of the early phase of bright TDE X-ray flares with joint XMM and Swift observations. The observations would lead to the first detection of BP disks expected around spinning SMBHs and the first application of reverberation mapping of the innermost accretion flow around a previously quiescent SMBH.|

|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.
