Description
Unusual patterns of variability in X-ray sources can hold clues to the identities of hard to classify sources, and can be indicators of rare and exotic astrophysical phenomena like magnetar outbursts and Quasi-Periodic Eruptions in AGN. The ability to adequately identify interesting sources through their time-domain variability can often be difficult with the large volumes of data being produced, and in the archives of large missions like XMM-Newton and Chandra. This problem will become ever more important with the anticipated launch of larger observatories like NewAthena in the next decade. Here I will present the preliminary results of an investigation into the use of classifiers for the identification of the rare phenomenon in AGN, Quasi-Periodic Eruptions and Quasi-Periodic Oscillations, and outline a route map for the development of an ensemble classifier aimed at providing robust predictions of sources solely through features extracted from their X-ray lightcurves.
