The new method adopted to determine the turbulence acceleration timescale
follows [miniati2015] and [pinzke2017], in which the merger-induced turbulence
cascades into small scales (and thus accelerate electrons) through the
TTD (transit-time damping) mechanism by scattering mainly with the
relativistic particles (cosmic-ray protons and electrons).
