For events as violent as the core-collapse of stars and merger of black
holes, one of the largest portions of energy released is through
gravitational radiation. This leads to a number o important issues. For
instance, does there exist any mechanism by which some of the GW energy may
be transferred to photons and other particles? If such a mechanism
exists, how relevant is it for energetic events like gamma ray bursts
(GRBs). Here we consider the propagation of light from an isolated source
that emits gravitational waves .The eikonal approach is employed to
determine the transfer of energy from the gravitational to electromagnetic
radiation. It is found that, a significant upshift of photon energy can
occur according to a power-law buildup over the radial distance. This
somewhat surprising effect may be responsible for some of the unexplained
high energy phenomena in the cosmos involving gamma rays or other forms of
astro-particles.
