N2 - The process of jet formation in accreting black holes, and the
conditions under which it occurs is currently hotly debated, with
competing models predicting the jet power to be governed by black hole
spin, the magnetic field strength, the location of the jet base, the
mass accretion rate and/or the properties of the inner accretion flow.
We present new results that show empirical correlations between the
accretion flow properties and the spectral energy distribution of the
jets launched from accreting black holes. The X-ray power law is
directly related to the particle energy distribution in the hot
accretion flow. We find that the photon index of this power law
correlates with the characteristic break frequency in the jet spectrum
emitted near the jet base, and the jet luminosity up to the break
frequency. The observed correlations can be explained by the energy
distribution of electrons in the hot accretion flow being subsequently
channeled into the jet. These correlations represent a new
inflow--outflow connection in accreting black holes, and demonstrate
that the spectral properties of the jet rely most critically on the
conditions in the inner accretion flow, rather than other parameters
such as the black hole mass or spin.
