|Title||A Quick, Hard Look at a Bright Tidal Disruption Candidate|
|Author||Dr Jon Miller|
|Description||Disruptions of stars by massive black holes in distant galaxies represent a rich discovery space. Not only can the predictions of such extreme encounters be tested, but disk and jet formation can be observed directly, and the strong gravitational environment near the black hole can be explored. Exploiting this rich potential requires a quick, sensitive observation, early in the evolution of an X-ray-bright flare. Two such flares have been detected within the last two years; in one, we recently discovered X-ray QPOs using XMM-Newton. We request a 98 ksec (70 ksec plus overheads) observation of a new X-ray-bright tidal disruption flare, within approximately 7 days of its discovery.|

|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.
