Query: On the role of fast magnetic reconnection in accreting black hole
  sources   We attempt to explain the observed radio and gamma-ray emission produced in
the surrounds of black holes by employing a magnetically-dominated accretion
flow (MDAF) model and fast magnetic reconnection triggered by turbulence. In
earlier work, standard disk model was used and we refine the model by focussing
on the sub-Eddington regime to address the fundamental plane of black hole
activity. The results do not change substantially with regard to previous work
ensuring that the details of the accretion physics are not relevant in the
magnetic reconnection process occurring in the corona. Rather our work puts
fast magnetic reconnection events as a powerful mechanism operating in the core
region, near the jet base of black hole sources on more solid ground. For
microquasars and low-luminosity active galactic nuclei (LLAGNs) the observed
correlation between radio emission and mass of the sources can be explained by
this process. The corresponding gamma-ray emission also seems to be produced in
the same core region. On the other hand, the emission from blazars and
gamma-ray bursts (GRBs) cannot be correlated to core emission based on fast
reconnection.
