| Abstract | A dedicated monitoring campaign with XMM, Swift, NICER, Chandra and eROSITA overthe past 4+ years has unveiled a surprising second outburst from the tidaldisruption event (TDE) AT2018fyk. This dramatic X-ray and UV re-brightening hasbeen interpreted as the signature of a repeating partial TDE. We are requestinga 30 ks XMM exposure of AT2018fyk during the upcoming accretion shut off phase,which is estimated to occur during mid-late 2023. Our main goal is to track theX-ray spectral evolution during this second outburst and compare it with theprevious flare. While we currently continue to track AT2018fyk with NICER andSwift through GO and DDT programs, only XMM has large enough effective area andsensitivity to facilitate a high signal-to-noise spectrum in the next low-flux state. |

| 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. |
