An artist's impression of a relativistic jet propagating away from a black hole at close to the speed of light. Such jets are formed by the inner regions of the accretion flow: matter flowing inwards towards the black hole, via processes which are not yet fully understood. The accretion flow emits primarily in X-rays, the relativistic jet in the radio band: by combing observations in each band we can try and understand how such jets form and how much energy they carry away from the black hole.

Abstract:

Relativistic jets powered by stellar mass black holes in X-ray binaries appear to come in two types: steady outflows associated with hard X-ray states and large scale discrete ejections associated with transient outbursts. We show that the broadband radio spectrum of a `quiescent' stellar mass black hole closely resembles that of canonical hard state sources emitting at four orders of magnitude higher X-ray levels, suggesting that a relativistic outflow is being formed down to at least a few 10^(-6) times the Eddington X-ray luminosity. We further report on the discovery of a low surface brightness radio nebula around the stellar black hole in Cyg X-1, and discuss how it can be used as an effective calorimeter for the jet kinetic power.
