Abstract for Proposal 096065

SWIFT-XRT + XMM ToO follow-up of a new eROSITA QPE candidate

To date, only 8 bona-fide QPE sources are publicly known, of which only 4 were found through systematic X-ray searches allowing a calculation of their intrinsic volumetric rates. eROSITA archival data, despite the halt of operations, are still being screened to provide further candidates. We request followup on a further QPE candidate from eROSITA, which was recently re-prioritized based on its recent counterpart identification with a galaxy. Deep XMM data are needed for characterization of both eruptions and quiescence, although we conservatively request ~21ks of Swift-XRT time to trigger, in case eruptions are observed, a full XMM-Newton orbit with P_trigger~60%%.
