Discovery of a soft X-ray lag in the Ultraluminous X-ray Source NGC 1313 X-1
E. Kara, C. Pinto, D. J. Walton +14
Ultraluminous X-ray Sources (ULXs) provide a unique opportunities to probe the geometry and energetics of super-Eddington accretion. The radiative processes involved in super-Eddin…
An ionised accretion disc wind in Hercules X-1
P. Kosec, A. C. Fabian, C. Pinto +3
Hercules X-1 is one of the best studied highly magnetised neutron star X-ray binaries with a wealth of archival data. We present the discovery of an ionised wind in its X-ray spect…
The Unusual Broadband X-ray Spectral Variability of NGC 1313 X-1 seen with XMMNewton, Chandra and NuSTAR
D. J. Walton, C. Pinto, M. Nowak +19
We present results from the major coordinated X-ray observing program on the ULX NGC 1313 X-1 performed in 2017, combining -, and , focusing on the e…
XMM-Newton Campaign On Ultraluminous X-ray Source NGC 1313 X-1: Wind vs. State Variability
C. Pinto, D. J. Walton, E. Kara +12
Most ultraluminous X-ray sources (ULXs) are thought to be powered by neutron stars and black holes accreting beyond the Eddington limit. If the compact object is a black hole or a…
NICER Discovers Spectral Lines During Photospheric Radius Expansion Bursts from 4U 1820-30: Evidence for Burst-driven Winds
T. E. Strohmayer, D. Altamirano, Z. Arzoumanian +14
We report the discovery with the Neutron Star Interior Composition Explorer (NICER) of narrow emission and absorption lines during photospheric radius expansion (PRE) X-ray bursts…
Thermal stability of winds driven by radiation pressure in super-Eddington accretion disks
Ciro Pinto, Missagh Mehdipour, Dom J. Walton +7
Ultraluminous X-ray sources (ULXs) are mainly powered by accretion in neutron stars or stellar-mass black holes. Accreting at rates exceeding the Eddington limit by factors of a fe…
