Black Hole Binaries observed with INTEGRAL
Abstract
Galactic Black Hole Binaries show several and complex spectral behaviours and transitions. I will review INTEGRAL observation results, focussing on the high-energy emission of BHBs. In particular I will present INTEGRAL and Swift observations of the GRS 1915+105-like source IGR J17091-3624 and the peculiar outburst of the new black-hole candidate MAXI J1836-194. Finally, I will briefly report on the long-term behaviour and a spectral variability study of Cyg X-1 performed with INTEGRAL and the new model BELM, explaining the hard X-ray spectral shape and estimating the magnetic field in the electron plasma.
