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 sky behind our galaxy as seen by IBIS on INTEGRAL
L. Bassani, A. Malizia, J. B. Stephen +16
During the Core Programme, INTEGRAL has surveyed a large portion of the sky (around 9000 square degrees); although INTEGRAL is not optimized for extra-galactic studies its observat…
Integral/IBIS Observations of persistent black hole spectral states during the Core Program
P. Laurent, P. Goldoni, A. Goldwurm +1
The Imager on Board the Integral Satellite (IBIS) is one of the two main telescopes of Integral, the ESA soft gamma-ray mission to be launched in 2002. The Integral Core Program wi…
INTEGRAL observations of Galaxy Clusters
P. Goldoni, A. Goldwurm, P. Laurent +3
Cluster of galaxies are the largest concentrations of visible mass in the Universe and therefore a fundamental topic of cosmology and astrophysics. Recent radio, EUV, and X-ray obs…
Observation of a Black-Hole X-ray Nova in Outburst with INTEGRAL
P. Goldoni, A. Goldwurm, P. Laurent +2
We simulate the observation of a bright Nova Musca-like X-ray nova during outburst with INTEGRAL, the next ESA gamma-ray space observatory. We will show how performances of the INT…
Hard X-Rays from the Galactic Nucleus: Present and Future Observations
A. Goldwurm, P. Goldoni, P. Laurent +2
In spite of increasing evidences of the presence of a massive Black Hole at the Galactic Center, its radio counterpart, Sgr A*, shows little activity at high energies, and recent m…
