Fast Radio Bursts and the Axion Quark Nugget Dark Matter Model
  We explore the possibility that the Fast Radio Bursts (FRBs) are powered by
magnetic reconnection in magnetars, triggered by Axion Quark Nugget (AQN) dark
matter. In this model, the magnetic reconnection is ignited by the shock wave
which develops when the nuggets' Mach number $M \gg 1$. These shock waves
generate very strong and very short impulses expressed in terms of pressure
$\Delta p/p\sim M^2$ and temperature $\Delta T/T\sim M^2$ in the vicinity of
(would be) magnetic reconnection area. We find that the proposed mechanism
produces a coherent emission which is consistent with current data, in
particular the FRB energy requirements, the observed energy distribution, the
frequency range and the burst duration. Our model allows us to propose
additional tests which future data will be able to challenge.
