A Multi-Wavelength Picture of the Surprisingly Short 2024/25 Outburst from EXO 0748-676
Amy H. Knight, Lauren Rhodes, Noel Castro Segura +11
After sixteen years in quiescence, EXO 0748-676 unexpectedly returned to outburst in March 2024. However, in stark contrast to its previous outburst (1985 - 2008), EXO 0748-676 ret…
A Broadband X-ray Analysis and Optical Counterpart Search of IC5052 ULX
Nabil Brice, Dominic J. Walton, Felix Fürst +10
We present broadband X-ray spectral and timing analysis of the Ultra-luminous X-ray source (ULX) in IC5052 using simultaneous XMM-Newton and NuSTAR observations from 2022, suppleme…
Significant or Not? The Impact of Randomisation During Data Reduction on Confirming a New Pulsating Ultraluminous X-ray Source Candidate in Centaurus A
Amy H. Knight, Timothy P. Roberts, Callum Potter +2
We report the discovery of a new candidate pulsating ultraluminous X-ray source (PULX) in NGC 5128 (Centaurus A). The candidate, 4XMM J132542.2-425943, is a transient source, ident…
Type I X-ray Burst Emission Reflected into the Eclipses of EXO 0748-676
Amy H. Knight, Jakob van den Eijnden, Adam Ingram +8
The neutron star X-ray binary, EXO 0748--676, was observed regularly by the Rossi X-ray Timing Explorer (RXTE) and XMM-Newton during its first detected outburst (1985 - 2008). Thes…
Long term optical variations in Swift J1858.6-0814: evidence for ablation and comparisons to radio properties
L. Rhodes, D. M. Russell, P. Saikia +5
We present optical monitoring of the neutron star low-mass X-ray binary Swift J1858.6-0814 during its 2018-2020 outburst and subsequent quiescence. We find that there was strong op…
Simultaneous Optical and X-ray Detection of a Thermonuclear Burst in the 2024 Outburst of EXO 0748-676
Amy H. Knight, Lauren Rhodes, Douglas J. K. Buisson +5
The neutron star low-mass X-ray binary, EXO 0748--676, recently returned to outburst after a 16 year-long quiescence. Since its return, there has been a global effort to cap…
The Link Between Neutron Star X-ray Binaries and Spider Pulsars
Amy H. Knight, Adam Ingram, Jakob van den Eijnden +3
The discovery of transitional millisecond pulsars (tMSPs) provided conclusive proof that neutron star (NS) low-mass X-ray binaries (LMXBs) comprise part of the evolutionary pathway…
X-ray Eclipse Mapping Constrains the Binary Inclination and Mass Ratio of Swift J1858.6-0814
Amy H. Knight, Adam Ingram, Matthew Middleton
X-ray eclipse mapping is a promising modelling technique, capable of constraining the mass and/or radius of neutron stars (NSs) or black holes (BHs) in eclipsing binaries and probi…
Eclipse Mapping of EXO 0748-676: Evidence for a Massive Neutron Star
Amy H. Knight, Adam Ingram, Matthew Middleton +1
Determining the maximum possible neutron star (NS) mass places limits on the equation of state (EoS) of ultra-dense matter. The mass of NSs in low mass X-ray binaries can be determ…
