An 8.56 keV absorption line in the hyperluminous X-ray source in NGC 4045: ultra-fast outflow or cyclotron line?
Murray Brightman, Peter Kosec, Felix Fürst +5
We report on the discovery of an absorption line at keV detected with a significance of in the NuSTAR and XMM-Newton spectra of a newly discovered…
Reconstruction of the NuSTAR point spread function using single-laser metrology
Hannah P. Earnshaw, Kristin K. Madsen, Karl Forster +4
This paper describes a method by which the metrology system of the Nuclear Spectroscopic Telescope Array (NuSTAR) X-ray space observatory, which uses two lasers to characterize the…
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…
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…
