We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J1946+274 is aExpand
Multiple cyclotron line-forming regions in GX 301−2
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 described by typicalExpand
Cyclotron resonant scattering feature simulations. II. Description of the CRSF simulation process
Context. Cyclotron resonant scattering features (CRSFs) are formed by scattering of X-ray photons off quantized plasma electrons in the strong magnetic field (of the order 10^(12) G) close to theExpand
Evidence for different accretion regimes in GRO J1008-57
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 evolution of theExpand
The TANAMI Multiwavelength Program: Dynamic spectral energy distributions of southern blazars⋆
We thank the referee for helpful comments. We thank S. Cutini for her useful comments. We thank S. Markoff for helpful discussions. We thank J. Perkins, L. Baldini, and S. Digel for carefully readingExpand
SIXTE: a generic X-ray instrument simulation toolkit
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 instrumentation. The packageExpand
Cyclotron resonant scattering feature simulations I. Thermally averaged cyclotron scattering cross sections, mean free photon-path tables, and electron momentum sampling
Context. Electron cyclotron resonant scattering features (CRSFs) are observed as absorption-like lines in the spectra of X-ray pulsars. A significant fraction of the computing time for Monte CarloExpand
Formation of phase lags at the cyclotron energies in the pulse profiles of magnetized, accreting neutron stars
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 particular close toExpand
Suzaku observations of the 2013 outburst of KS 1947+300
We report on the timing and spectral analysis of two Suzaku observations with different flux levels of the high-mass X-ray binary KS 1947+300 during its 2013 outburst. In agreement with simultaneousExpand
A multi-model approach to X-ray pulsars - Connecting spectral and timing models to pin down the intrinsic emission characteristics of magnetized, accreting neutron stars
The emission characteristics of X-ray pulsars are governed by magnetospheric accretion within the Alfven radius, leading to a direct coupling of accretion column properties and interactions at theExpand
