| Description | The hyperluminous off-center X-ray source 3XMM J215022.4-055108 is the only known off-center tidal disruption event (TDE) harbouring one of the most solid intermediate mass black hole (IMBH) candidates. We request XMM-Newton to continue the long-term monitoring of this unique object in AO20 for 60 ks. The goals are (1) to test whether accreting massive black holes (BHs) exhibit similar spectral states as seen in accreting stellar-mass BHs and (2) to test whether its luminosity continues to follow the standard t^-5/3 decay for TDEs. |

| 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. |
