Needle in a Poissonian haystack -- An X-ray astronomer's guide to QPE fishing

E. Quintin, N. Khan, N. A. Webb +4

After six years of studies following the discovery of GSN069, a link is starting to appear between the elusive Quasi-Periodic Eruptions (QPEs) and other types of nuclear transients…

4XMM J175136.8-275858: A New Magnetar Candidate?

Robbie Webbe, Norman Khan, N. A. Webb +1

Magnetars are very rare astrophysical objects, with 31 known to date. They are best understood as highly magnetised neutron stars, but a greater number need to be found to co…

The EXOD search for faint transients in XMM-Newton observations. Part II

Norman Khan, Erwan Quintin, Natalie A. Webb +7

The XMM-Newton observatory has accumulated a vast archive of over 17,000 X-ray observations over the last 25 years. However, the standard data processing pipelines may fail to dete…

Long-Term X-Ray/UV Variability in ULXs

Norman Khan, Matthew. J. Middleton

The focus of NASA's Swift telescope has been transients and target-of-opportunity observing, resulting in many observations of ultraluminous X-ray sources (ULXs) over the last ~20…

Thermally driven winds in ULXs

Matthew Middleton, Nick Higginbottom, Christian Knigge +2

The presence of radiatively driven outflows is well established in ultraluminous X-ray sources (ULXs). These outflows are optically thick and can reprocess a significant fraction o…

Predicting the self-lensing population in optical surveys

Grzegorz Wiktorowicz, Matthew Middleton, Norman Khan +3

The vast majority of binaries containing a compact object and a regular star spend most of their time in a quiescent state where no strong interactions occur between components. De…
