Searching for quasi-periodic eruptions using machine learning

Young, A. J.; Webbe, Robbie

Quasi-periodic eruption (QPE) is a rare phenomenon in which the X-ray emission from the nuclei of galaxies shows a series of large amplitude flares. Only a handful of QPEs have been observed but the possibility remains that there are as yet undetected sources in archival data. Given the volume of data available a manual search is not feasible, and…

An investigation into the effect of exposing XMM-Newton's Optical Monitor to the light of Jupiter

Sullivan, S; Page, M J; Breeveld, A A +2 more

After nearly 18 yr of successful and safe operations, on 2017 July 17 and 18, XMM-Newton's Optical Monitor (OM) observed Jupiter - an object 10 magnitudes brighter than safe brightness limits - in its visual (V) filter. The object was exposed 40 arcsec from the nominal European Photon Imaging Cameras pn boresight in the negative Y direction, creat…
