|Description||Theorists first surmised that massive black holes (MBHs) will inevitably tidally disrupt and consume stars in their vicinity, and that the resulting flare of radiation could be used as a signpost for a dormant MBH lurking otherwise undetectable in the center of a galaxy. In the last decade, major progress has been made in the discovery of candidates using surveys across the electromagnetic spectrum, from the X-rays to the optical. We propose for TOO XMM-Newton X-ray imaging of TDE candidates from the Pan- STARRS1 Medium Deep Survey in order to characterize the prompt X-ray properties of optically-selected candidates for the first time.|

|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.
