X-ray emission from magnetized neutron star atmospheres at low mass accretion rates. I. Phase-averaged spectrum
E. Sokolova-Lapa, M. Gornostaev, J. Wilms +12
Recent observations of X-ray pulsars at low luminosities allow, for the first time, to compare theoretical models for the emission from highly magnetized neutron star atmospheres a…
SIXTE -- The Generic X-ray Instrument Simulation Toolkit
Thomas Dauser, Sebastian Falkner, Maximilian Lorenz +8
We give an overview of the SImulation of X-ray TElescopes (SIXTE) software package, a generic, mission-independent Monte Carlo simulation toolkit for X-ray astronomical instrumenta…
Spectral and Timing Analysis of the accretion-powered pulsar 4U 1626-67 observed with Suzaku and NuSTAR
Wataru B. Iwakiri, Katja Pottschmidt, Sebastian Falkner +13
We present an analysis of the spectral shape and pulse profile of the accretion-powered pulsar 4U 1626-67 observed with Suzaku and NuSTAR during a spin-up state. The pulsar, which…
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…
Evidence for different accretion regimes in GRO J1008-57
Matthias Kühnel, Felix Fürst, Katja Pottschmidt +6
We present a comprehensive spectral analysis of the BeXRB GRO J1008-57 over a luminosity range of three orders of magnitude using NuSTAR, Suzaku and RXTE data. We find significant…
The Goodness of Simultaneous Fits in ISIS
Matthias Kühnel, Sebastian Falkner, Christoph Grossberger +15
In a previous work, we introduced a tool for analyzing multiple datasets simultaneously, which has been implemented into ISIS. This tool was used to fit many spectra of X-ray binar…
