摘要：The long-term monitoring campaign of Cyg X-1 has provided the detection of the first simultaneous
radio/X-ray flare seen from that source. We investigate the physical characteristics of the
event in terms of emission from a homogeneous, expanding blob of pair-plasma, superimposed
on a baseline flux in both bands. We find that while the radio flare can be reconstructed under
various configurations of a cooling blob, continuous (re)acceleration of particles inside the jet is
necessary to sustain X-ray emission at the levels implied by the data, for the observed duration.
We present major results of the modelling and discuss implications for the role of microquasar
jets.
