Radio observations of extreme ULXs: revealing the most powerful ULX radio nebula ever or the jet of an intermediate-mass black hole?
M. Mezcua, T. P. Roberts, A. D. Sutton +1
The most extreme ultraluminous X-ray sources (ULXs), with erg s, are amongst the best candidates for hosting intermediate-mass black holes…
The ultraluminous state revisited: fractional variability and spectral shape as diagnostics of super-Eddington accretion
Andrew D. Sutton, Timothy P. Roberts, Matthew J. Middleton
Although we are nearing a consensus that most ULXs are stellar-mass black holes in a super-Eddington state, little is yet established of the physics of this accretion mode. Here, w…
A bright ultraluminous X-ray source in NGC 5907
Andrew D. Sutton, Timothy P. Roberts, Jeanette C. Gladstone +4
We present a multi-mission X-ray analysis of a bright (peak observed 0.3-10 keV luminosity of ~ 6x10^{40} erg s^{-1}), but relatively highly absorbed ULX in the edge-on spiral gala…
