The giant outburst of 4U 0115+634 in 2011 with Suzaku and RXTE
Matthias Bissinger né Kühnel, Ingo Kreykenbohm, Carlo Ferrigno +19
We present an analysis of X-ray spectra of the high mass X-ray binary 4U 0115+634 as observed with Suzaku and RXTE in 2011 July, during the fading phase of a giant X-ray outburst.…
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…
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…
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…
The NuSTAR X-ray Spectrum of Hercules X-1: A Radiation-Dominated Radiative Shock
Michael T. Wolff, Peter A. Becker, Amy M. Gottlieb +7
We report new spectral modeling of the accreting X-ray pulsar Hercules X- 1. Our radiation-dominated radiative shock model is an implementation of the analytic work of Becker & Wol…
Simultaneous fits in ISIS on the example of GRO J1008-57
Matthias Kühnel, Sebastian Müller, Ingo Kreykenbohm +9
Parallel computing and steadily increasing computation speed have led to a new tool for analyzing multiple datasets and datatypes: fitting several datasets simultaneously. With thi…
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…
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…
No anti-correlation between cyclotron line energy and X-ray flux in 4U 0115+634
Sebastian Müller, Carlo Ferrigno, Matthias Kühnel +18
We report on an outburst of the high mass X-ray binary 4U 0115+63 with a pulse period of 3.6s in 2008 March/April as observed with RXTE and INTEGRAL. During the outburst the neutro…
Understanding the Last Mile - Physics of the Accretion Column
Peter Kretschmar, Peter A. Becker, Dipankar Bhattacharya +17
Accreting X-ray pulsars are among the best observed objects of X-ray astronomy with a rich data set of observational phenomena in the spectral and timing domain. While the general…
A Suzaku View of Cyclotron Line Sources and Candidates
K. Pottschmidt, S. Suchy, E. Rivers +20
Seventeen accreting neutron star pulsars, mostly high mass X-ray binaries with half of them Be-type transients, are known to exhibit Cyclotron Resonance Scattering Features (CRSFs)…
