A Multi-Mission Catalogue of Ultraluminous X-ray Source Candidates
D. J. Walton, A. D. A. Mackenzie, H. Gully +4
We present a new, multi-mission catalogue of ultraluminous X-ray source (ULX) candidates, based on recent data releases from each of the XMM-Newton, Swift and Chandra observatories…
The chameleon on the branches: spectral state transition and dips in NGC 247 ULX-1
A. D'Aì, C. Pinto, M. Del Santo +14
Soft Ultra-Luminous X-ray (ULXs) sources are a subclass of the ULXs that can switch from a supersoft spectral state, where most of the luminosity is emitted below 1 keV, to a soft…
Broadband X-ray spectral variability of the pulsing ULX NGC 1313 X-2
A. Robba, C. Pinto, D. J. Walton +12
It is thought that ultraluminous X-ray sources (ULXs) are mainly powered by super-Eddington accreting neutron stars or black holes as shown by recent discovery of X-ray pulsations…
Quasi-periodic dipping in the ultraluminous X-ray source, NGC 247 ULX-1
W. N. Alston, C. Pinto, D. Barret +15
Most ultraluminous X-ray sources (ULXs) are believed to be stellar mass black holes or neutron stars accreting beyond the Eddington limit. Determining the nature of the compact obj…
Long-term pulse period evolution of the ultra-luminous X-ray pulsar NGC 7793 P13
F. Fuerst, D. J. Walton, M. Heida +14
Ultra-luminous X-ray pulsars (ULXPs) provide a unique opportunity to study super-Eddington accretion. We present the results of a monitoring campaign of ULXP NGC 7793 P13. Over our…
XMM-Newton campaign on the ultraluminous X-ray source NGC 247 ULX-1: outflows
C. Pinto, R. Soria, D. Walton +13
Most ULXs are believed to be powered by super-Eddington accreting neutron stars and, perhaps, black holes. Above the Eddington rate the disc is expected to thicken and to launch po…
