5 years of survey on the Crab Nebula with SPI/INTEGRAL
E. Jourdain, J. P. Roques
We present observations of the Crab Nebula above 20 keV by the SPI/INTEGRAL telescope during more than 5 years of operations. Our study demonstrates the stability of the instrument…
Hard X-ray emission of the microquasar GX 339-4 in the low/hard state
A. Joinet, E. Jourdain, J. Malzac +4
We present the analysis of the high energy emission of the Galactic black hole binary GX 339-4 in a low/hard state at the beginning of its 2004 outburst. The data from 273 ks of IN…
Bimodal spectral variability of Cygnus X-1 in an intermediate state
J. Malzac, P. O. Petrucci, E. Jourdain +11
We report the results of an observation of Cygnus X-1 with INTEGRAL, that we combine with simultaneous radio observations with the Ryle telescope. Both spectral and variability pro…
Integral observation of Cyg X-1 in an intermediate state
J. Malzac, P. O. Petrucci, E. Jourdain +11
We present preliminary results of an observation of Cygnus X-1 with INTEGRAL performed on June 7-11 2003. Both spectral and variability properties of the source indicate that Cygnu…
The European Photon Imaging Camera on XMM-Newton: The MOS Cameras
M. J. L. Turner, A. Abbey, M. Arnaud
The EPIC focal plane imaging spectrometers on XMM-Newton use CCDs to record the images and spectra of celestial X-ray sources focused by the three X-ray mirrors. There is one camer…
Long-Term Variability of the Hard X-ray Source GRS 1758-258: GRANAT/SIGMA Observations
S. I. Kuznetsov, M. R. Gilfanov, E. M. Churazov +13
The results of GRANAT/SIGMA hard X-ray observations of GRS 1758-258 in 1990-1998 are presented. The source lies at ~5\arcdeg from the Galactic Center and was within the SIGMA field…
