The causal connection between disc and power-law variability in hard state black hole X-ray binaries
P. Uttley, T. Wilkinson, P. Cassatella +4
We use the XMM-Newton EPIC-pn instrument in timing mode to extend spectral time-lag studies of hard state black hole X-ray binaries into the soft X-ray band. We show that variation…

Pulse-phase resolved spectroscopy of continuum and reflection in SAX J1808.4-3658
Tony Wilkinson, Alessandro Patruno, Anna Watts +1
We perform phase-resolved spectroscopy of the accreting millisecond pulsar, SAX J1808.4-3658, during the slow-decay phase of the 2002 outburst. Simple phenomenological fits to RXTE…

Accretion disc variability in the hard state of black hole X-ray binaries
Tony Wilkinson, Philip Uttley
XMM-Newton X-ray spectra of the hard state Black Hole X-Ray Binaries (BHXRBs) SWIFT J1753.5-0127 and GX 339-4 show evidence for accretion disc blackbody emission, in addition to ha…
