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…
INTEGRAL, XMM-Newton and Rossi-XTE Observations of the State Transition of the X-ray Transient and Black Hole Candidate XTE J1720-318
Marion Cadolle Bel, Andrea Goldwurm, Jerome Rodriguez +14
We report the results of extensive high-energy observations of the X-ray transient and black hole candidate XTE J1720-318 performed with INTEGRAL, XMM-Newton and RXTE. The source,…
Contribution of point sources to the soft gamma-ray Galactic emission
Regis Terrier, Francois Lebrun, Guillaume Belanger +6
The nature of the soft gamma-ray (20-200 keV) Galactic emission has been a matter of debate for a long time. Previous experiments have tried to separate the point source contributi…
Al(26) Studies with INTEGRAL's Spectrometer SPI
R. Diehl, K. Kretschmer, G. Lichti +13
Al(26) radioactivity traces recent nucleosynthesis throughout the Galaxy, and is known to be produced in massive stars and novae. The map from its decay gamma-ray line suggests mas…
SPI science prospects
Jurgen Knodlseder, Jean-Pierre Roques
With the launch of ESA's INTEGRAL satellite in october 2002, a gamma-ray observatory will become available to the scientific community that combines imaging and spectroscopic capac…
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…
