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…
First look at Vela X-1 with XRISM: A simultaneous campaign with XMM-Newton and NuSTAR
C. M. Diez, S. Dupourqué, M. Zhou +6
High-Mass X-ray Binaries (HMXBs) serve as useful laboratories for exploring the behaviour of accreted matter onto compact objects and for probing the complex wind environments of m…
The population of hyperluminous X-ray sources as seen by XMM-Newton
Roberta Amato, Erwan Quintin, Hugo Tranin +7
Ultraluminous and hyperluminous X-ray sources (ULXs and HLXs) are among the brightest astrophysical objects in the X-ray sky. While ULXs most likely host stellar-mass compact objec…
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…
STONKS: Quasi-real time XMM-Newton transient detection system
E. Quintin, N. A. Webb, I. Georgantopoulos +6
Over recent decades, astronomy has entered the era of massive data and real-time surveys. This is improving the study of transient objects - although they still contain some of the…
Tormund's return: Hints of quasi-periodic eruption features from a recent optical tidal disruption event
E. Quintin, N. A. Webb, S. Guillot +8
Quasi-periodic eruptions (QPEs) are repeating thermal X-ray bursts associated with accreting massive black holes, the precise underlying physical mechanisms of which are still uncl…
Tidal disruption events and quasi periodic eruptions
Natalie A. Webb, Didier Barret, Olivier Godet +4
Tidal disruption events (TDEs) occur when a star passes close to a massive black hole, so that the tidal forces of the black hole exceed the binding energy of a star and cause it t…
