The evolution of black hole binaries
The past decade has seen an incredible increase in the amount of available X-ray data of black-hole binaries, thanks to the RossiXTE satellite. At the same time, the development of solid multi- wavelength programs has led to the discovery of relativistic jets from these systems and their complex relation to the accretion properties. Although the phenomenology appears at first sight to be intractable, delving into the trove of available data and using appropriate tools, it is possible to reach basic conclusions about the spectral/timing behaviour during the outburst of transient systems. I will describe the unified picture that we have reached for transient systems and how it can be connected to the properties of jet ejection. This paradigm can be applied also to persistent systems such as Cygnus X-1 and even to Active Galactic Nuclei.
