The role of the reflection fraction in constraining black hole spin
T. Dauser, J. Garcia, M. L. Parker +2
In many active galaxies, the X-ray reflection features from the innermost regions of the accretion disc are relativistically distorted. This distortion allows us to measure paramet…
The NuSTAR spectrum of Mrk 335: Extreme relativistic effects within 2 gravitational radii of the event horizon?
M. L. Parker, D. R. Wilkins, A. C. Fabian +18
We present 3-50 keV NuSTAR observations of the AGN Mrk 335 in a very low flux state. The spectrum is dominated by very strong features at the energies of the iron line at 5-7 keV a…
Formation of phase lags at the cyclotron energies in the pulse profiles of magnetized, accreting neutron stars
G. Schönherr, F. -W. Schwarm, S. Falkner +13
Context: Accretion-powered X-ray pulsars show highly energy-dependent and complex pulse-profile morphologies. Significant deviations from the average pulse profile can appear, in p…
