  We investigate the non-linear interaction of a strong Gravitational Wave with
the plasma during the collapse of a massive magnetized star to form a black
hole, or during the merging of neutron star binaries (central engine). We found
that under certain conditions this coupling may result in an efficient energy
space diffusion of particles. We suggest that the atmosphere created around the
central engine is filled with 3-D magnetic neutral sheets (magnetic nulls). We
demonstrate that the passage of strong pulses of Gravitational Waves through
the magnetic neutral sheets accelerates electrons to very high energies.
Superposition of many such short lived accelerators, embedded inside a
turbulent plasma, may be the source for the observed impulsive short lived
bursts. We conclude that in several astrophysical events, gravitational pulses
may accelerate the tail of the ambient plasma to very high energies and become
the driver for many types of astrophysical bursts.
