ULX behaviour: the ultraluminous state, winds & interesting anomalies
T. P. Roberts, M. J. Middleton, A. D. Sutton +3
Recent evidence - in particular the hard X-ray spectra obtained by NuSTAR, and the large amplitude hard X-ray variability observed when ultraluminous X-ray sources (ULXs) show soft…
X-ray spectral residuals in NGC 5408 X-1: diffuse emission from star formation, or the signature of a super-Eddington wind?
Andrew D. Sutton, Timothy P. Roberts, Matthew J. Middleton
If ultraluminous X-ray sources (ULXs) are powered by accretion onto stellar remnant black holes, then many must be accreting at super-Eddington rates. It is predicted that such hig…
Diagnosing the accretion flow in ultraluminous X-ray sources using soft X-ray atomic features
Matthew J. Middleton, Dominic J. Walton, Andrew Fabian +5
The lack of unambiguous detections of atomic features in the X-ray spectra of ultraluminous X-ray sources (ULXs) has proven a hindrance in diagnosing the nature of the accretion fl…
The hyperluminous X-ray source candidate in IC 4320: another HLX bites the dust
Andrew D Sutton, Timothy P. Roberts, Jeanette C. Gladstone +1
The known members of the class of hyperluminous X-ray sources (HLXs) are few in number, yet they are of great interest as they are regarded as the likeliest intermediate-mass black…
The powerful jet of an off-nuclear intermediate-mass black hole in the spiral galaxy NGC 2276
M. Mezcua, T. P. Roberts, A. P. Lobanov +1
Jet ejection by accreting black holes is a mass invariant mechanism unifying stellar and supermassive black holes (SMBHs) that should also apply for intermediate-mass black holes (…
