STONKS first results: Long-term transients in the XMM-Newton Galactic plane survey
Robbie Webbe, E. Quintin, N. A. Webb +5
The study of astronomical transients at high energies provides insights into some of the most extreme physical events in the universe; however, carrying out their detection and fas…
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…
Discovering periodic and repeating nuclear transients in the XMM-Newton archives
Natalie A. Webb, Vincent Foustoul, Robbie Webbe +3
The regions around massive black holes can show X-ray variability on timescales from seconds to decades. Observing many black holes over different timescales can enhance our chance…
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…
Variability In A Low-Mass AGN: Oscillation Or Eruption?
Robbie Webbe, A. J. Young
Following the discovery of a new class of X-ray variability seen in four galaxies, dubbed Quasi-Periodic Eruptions (QPEs), we reconsider the variability seen in the low-mass AGN 2X…
