A possible phase dependent absorption feature in the transient X-ray pulsar SAX J2103.5+4545
McKinley C. Brumback, Ryan C. Hickox, Felix S. Fürst +5
We present an X-ray spectral and timing analysis of two observations of the transient Be X-ray binary SAX J2103.5+4545 during its April 2016 outburst, which was characteri…
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…
Looking at A 0535+26 at low luminosities with NuSTAR
Ralf Ballhausen, Katja Pottschmidt, Felix Fürst +12
We report on two NuSTAR observations of the HMXB A 0535+26 taken toward the end of its normal 2015 outburst at very low keV luminosities of erg/s an…
A precessing Be disk as a possible model for occultation events in GX 304-1
Matthias Kühnel, Richard E. Rothschild, Atsuo T. Okazaki +14
We report on the RXTE detection of a sudden increase in the absorption column density, , during the 2011 May outburst of GX 304-1. The increased up to…
Identification of the Hard X-ray Source Dominating the E > 25 keV Emission of the Nearby Galaxy M31
M. Yukita, A. Ptak, A. E. Hornschemeier +15
We report the identification of a bright hard X-ray source dominating the M31 bulge above 25 keV from a simultaneous NuSTAR-Swift observation. We find that this source is the count…
Cyclotron resonant scattering feature simulations. II. Description of the CRSF simulation process
F. -W. Schwarm, R. Ballhausen, S. Falkner +12
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…
