| Abstract | During its all-sky survey, eROSITA has uncovered a large population oftransients associated with the nuclei of otherwise quiescent galaxies. XMMfollow-up observations have proven vital to monitor their lightcurve andspectral evolution and probe their nature. These follow-up campaigns highlighteda diverse origin of the events, ranging from sources showing the characteristicsof canonical Tidal Disruption Events (TDEs) to others exhibiting significantre-brightening episodes requiring alternative interpretations (e.g., partialTDEs). Here, we ask for XMM ToO observations of 8 new nuclear transients detecedby eROSITA. We will probe the diversity of the spectral and temporal evolution,enabling an improved understanding of the X-ray evolution of TDEs, and their imposters. |

| 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. |
