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

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
