Long term variability of Cygnus X-1, III. Radio-X-ray correlations
T. Gleissner, J. Wilms, G. G. Pooley +7
Long time scale radio-X-ray correlations in black holes during the hard state have been found in many sources and there seems to emerge a universal underlying relationship which qu…
GX 301-2 as seen by Integral
I. Kreykenbohm, K. Pottschmidt, P. Kretschmar +9
We present observations of the High Mass X-ray Binary GX 301-2 taken during the Galactic Plane Scan (GPS) with Integral following our RXTE observations (Kreykenbohm et al. 2004). T…
INTEGRAL broadband spectroscopy of Vela X-1
P. Kretschmar, R. Staubert, I. Kreykenbohm +11
The wind-accreting X-ray binary pulsar and cyclotron line source Vela X-1 has been observed extensively during INTEGRAL Core Program observations of the Vela region in June-July an…
XMM-Newton Observations of the Be/X-ray transient A0538-66 in quiescence
P. Kretschmar, J. Wilms, R. Staubert +2
We present XMM-Newton observations of the recurrent Be/X-ray transient A0538-66, situated in the Large Magellanic Cloud, in the quiescent state. Despite a very low luminosity state…
Timing and Spectroscopy of Accreting X-ray Pulsars: the State of Cyclotron Line Studies
W. A. Heindl, R. E. Rothschild, W. Coburn +4
A great deal of emphasis on timing in the RXTE era has been on pushing toward higher and higher frequency phenomena, particularly kHz QPOs. However, the large areas of the RXTE poi…
On the deep minimum state in the Seyfert galaxy MCG-6-30-15
C. S. Reynolds, J. Wilms, M. C. Begelman +2
(abridged) We present a detailed spectral analysis of the first observation of the Seyfert 1 galaxy MCG-6-30-15 by the European Photon Imaging Camera on board the XMM-Newton observ…
