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…
Jet-Disc coupling in the accreting black hole XTEJ1118+480
Julien Malzac, Andrea Merloni, Andrew C. Fabian
We interpret the rapid correlated UV/optical/ X-ray variability of XTEJ1118+480 as a signature of the coupling between the X-ray corona and a jet emitting synchrotron radiation in…
Full radiative coupling in two-phase models for accreting black holes
Julien Malzac, Anne-Marie Dumont, Martine Mouchet
The emission from galactic black holes and Seyfert galaxies is generally understood in term of two-phase models (Haardt and Maraschi 1991, 1993). Such models postulate that a hot p…
Jet-disc coupling through a common energy reservoir in the black hole XTE J1118+480
Julien Malzac, Andrea Merloni, Andrew C. Fabian
We interpret the rapid correlated UV/optical/ X-ray variability of XTE J1118+480 as a signature of the coupling between the X-ray corona and a jet emitting synchrotron radiation in…
