A spectral-timing model for ULXs in the super-critical regime
Matthew Middleton, Lucy Heil, Fabio Pintore +2
Ultraluminous X-ray sources (ULXs) with luminosities lying between ~3x10^{39} - 2x10^{40} erg/s represent a contentious sample of objects as their brightness, together with a lack…
Discovery of a ~2 hr high frequency X-ray QPO and iron K alpha reverberation in the active galaxy MS 2254.9-3712
W. N. Alston, M. L. Parker, J. Markeviciute +5
We report the discovery of a Hz ( hr) X-ray quasi-periodic oscillation (QPO) in the active galaxy MS 2254.9-3712, using a ks XMM-Newton…
Detection of a QPO in 5 XMM-Newton observations of RE J1034+396
W. N. Alston, J. Markevičiūtė, E. Kara +2
The X-ray quasi-periodic oscillation (QPO) at Hz in RE J1034+396 has been robustly observed in the 0.2-10 keV band of one ks XMM-Newton observat…
The low or retrograde spin of the first extragalactic microquasar: implications for Blandford-Znajek powering of jets
Matthew Middleton, James Miller-Jones, Rob Fender
Transitions to high mass accretion rates in black hole X-ray binaries are associated with the ejection of powerful, relativistically-moving jets. The mechanism powering such events…
