NuSTAR reveals the hidden nature of SS433
M. J. Middleton, D. J. Walton, W. Alston +25
SS433 is the only Galactic binary system known to persistently accrete at highly super-critical (or hyper-critical) rates, similar to those in tidal disruption events, and likely n…
Multiple cyclotron line-forming regions in GX 301-2
F. Fuerst, S. Falkner, D. Marcu-Cheatham +6
We present two observations of the high-mass X-ray binary GX 301-2 with NuSTAR, taken at different orbital phases and different luminosities. We find that the continuum is well des…
A tale of two periods: determination of the orbital ephemeris of the super-Eddington pulsar NGC 7793 P13
F. Fuerst, D. J. Walton, M. Heida +10
We present a timing analysis of multiple XMM-Newton and NuSTAR observations of the ultra-luminous pulsar NGC 7793 P13 spread over its 65d variability period. We use the measured pu…
The Hard State of the Highly Absorbed High Inclination Black Hole Binary Candidate Swift J1658.2-4242 Observed by NuSTAR and Swift
Yanjun Xu, Fiona A. Harrison, Jamie A. Kennea +9
We present a spectral and timing analysis of the newly reported Galactic X-ray transient Swift J1658.2-4242 observed by NuSTAR and Swift. The broad-band X-ray continuum is typical…
Evidence for Pulsar-like Emission Components in the Broadband ULX Sample
D. J. Walton, F. Fuerst, M. Heida +7
We present broadband X-ray analyses of a sample of bright ultraluminous X-ray sources with the goal of investigating the spectral similarity of this population to the known ULX pul…
