Abstract | Tidal disruption events (TDEs), where a star is disrupted while passing close toa black hole, enable a view of accretion onto supermassive objects fromquiescence to super-Eddington rates, on a timescale of a few years. Here wepropose to characterise the spectral and temporal properties two TDEs found inAO15. As part of a comprehensive multiwavelength campaign we will use XMM-Newtonand HST to map either side of the expected hot black-body peak; search forevidence of non-thermal components; track the cooling of the event and study thelong and short timescale variability of the sources. In doing so we will createexquisite, panchromatic pictures of these extreme events. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
