Variable precession of the neutron star in Her X-1
R. Staubert, D. Klochkov, K. Postnov +3
We present evidence for an identical behavior of the precession of the accretion disk and that of the neutron star (NS) in Her X-1, based on investigating the well established 35 d…
Continuous monitoring of pulse period variations in Her X-1 using Swift/BAT
D. Klochkov, R. Staubert, K. Postnov +2
Context: Monitoring of pulse period variations in accreting binary pulsars is an important tool to study the interaction between the magnetosphere of the neutron star and the accre…
Updating the orbital ephemeris of Her X-1; rate of decay and eccentricity of the orbit
R. Staubert, D. Klochkov, J. Wilms
We present an update of the orbital ephemeris of the binary X-ray pulsar Her X-1 and determine an improved value for the rate of orbital decay. In addition, we report the first mea…
Episodic Random Accretion and the Cosmological Evolution of Supermassive Black Hole Spins
J. -M. Wang, C. Hu, Y. -R. Li +7
The growth of supermassive black holes (BHs) located at the centers of their host galaxies comes mainly from accretion of gas, but how to fuel them remains an outstanding unsolved…
Highly structured wind in Vela X-1
I. Kreykenbohm, J. Wilms, P. Kretschmar +6
We present an in-depth analysis of the spectral and temporal behavior of a long almost uninterrupted INTEGRAL observation of Vela X-1 in Nov/Dec 2003. In addition to an already hig…
INTEGRAL observation of hard X-ray variability of the TeV binary LS5039 / RX J1826.2-1450
A. D. Hoffmann, D. Klochkov, A. Santangelo +4
LS 5039/RX J1826.2-1450 is one of the few High Mass X-ray binary systems from which radio and high energy TeV emission has been observed. Moreover, variability of the TeV emission…
