Quasi Periodic Eruptions as EMRIs counterparts

Quasi Periodic Eruptions (QPEs) are a puzzling X-ray phenomena recently discovered in a number of sources with similar properties. In this talk, I am going to present a theoretical model that is able to reproduce their phenomenology in at least 4 sources. The QPEs arise from impacts between an Extreme Mass Ratio Inspiral (EMRI) object and a rigidly precessing TDE-like accretion disc. Since there seems to be a hint of correlation between some of the sources properties and TDEs host galaxy properties, modelling QPEs might eventually improve our understanding of the TDE demographics.
