A systematic assessment of the short-term X-ray behaviour of the Cas analogues
Robbie Webbe, Yaël Nazé, N. A. Webb
Context. Overall, Cas analogues represent a class of OBe stars displaying bright and hard X-ray emission. This emission was recently determined to be the result of accretion on…
Long-term investigation of gamma Cas analogs
Yael Naze, Gregor Rauw, Robbie Webbe +2
The subcategory of gamma Cas analogs gathers Be stars with bright and hard X-ray emission. Long-term variations are expected in such objects for two reasons: their Be disk builds a…
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…
The Effects of Instrumental Deadtime on NICER Timing Products
Robbie Webbe, A. J. Young
The X-ray Timing Instrument as part of the Neutron Star Interior Composition Explorer has the potential to examine the time-domain properties of compact objects in regimes not expl…
Searching for Quasi-Periodic Eruptions using Machine Learning
Robbie Webbe, A. J. Young
Quasi-Periodic Eruptions (QPEs) are 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…
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…
