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…
A unified accretion-ejection paradigm for Black Hole X-ray Binaries
J. Ferreira, P. O. Petrucci, G. Henri +2
We present a new picture for the central regions of Black Hole X-ray Binaries. In our view, these central regions have a multi-flow configuration which consists in (1) an outer sta…
The High Energy Spectrum of NGC 4151
V. Beckmann, C. R. Shrader, N. Gehrels +5
We present the first INTEGRAL observations of the type 1.5 Seyfert galaxy NGC 4151. Combining several INTEGRAL observations performed during 2003, totaling about 400 ks of exposure…
