Query: Coupling between the accreting corona and the relativistic jet in the
  micro quasar GRS 1915+105   GRS 1915+105 was the first stellar-mass black-hole in our Galaxy to display a
superluminal radio jet, similar to those observed in active galactic nuclei
with a supermassive black hole at the centre. It has been proposed that the
radio emission in GRS 1915+105 is fed by instabilities in the accretion disc by
which the inner parts of the accretion flow is ejected in the jet. Here we show
that there is a significant correlation between: (i) the radio flux, coming
from the jet, and the flux of the iron emission line, coming from the disc and,
(ii) the temperature of the corona that produces the high-energy part of the
X-ray spectrum via inverse Compton scattering and the amplitude of a
high-frequency variability component coming from the innermost part of the
accretion flow. At the same time, the radio flux and the flux of the iron line
are strongly anti-correlated with the temperature of the X-ray corona and the
amplitude of the high-frequency variability component. These correlations
persist over ~10 years, despite the highly variable X-ray and radio properties
of the source in that period. Our findings provide, for the first time,
incontrovertible evidence that the energy that powers this black-hole system
can be directed either to the X-ray corona or the jet. When this energy is used
to power the corona, raising its temperature, there is less energy left to fuel
the jet and the radio flux drops, and vice versa. These facts, plus the
modelling of the variability in this source show conclusively that in GRS
1915+105 the X-ray corona morphs into the jet.
