QPEs are extreme soft X-ray bursts recurring on hours timescales associated tolow-z galactic nuclei. Until a few months ago, only two such sources were foundand currently the only way of systematically finding new QPEs is provided bySRG/eROSITA. In AO19 we were able to discover, in synergy with XMM-Newton, twonew QPEs. Thanks to this pilot study, we are now confident in finding 3-4 goodcandidates every year. We plan to use 1-1.5yrs of eROSITA data to triggerXMM-Newton during AO20, therefore we ask for 4 ToO observations to be performedon 4 different candidates, each with a length of 130 ks. By the end of AO20 thissynergy can double the number of the now 4 known QPEs, which will allow us tobetter understand and characterise these new and interesting phenomena.

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.
