We consider the motion of a test particle around a Schwarzschild black hole. The particle's trajectory will deviate from a geodesic due to emission of gravitational radiation. The equation of motion of the test particle, under these circumstances, has been recently derived. The gravitational radiation reaction force is expressed as an integral over the particle's worldline, involving a tensorial retarded Green's function. We report results on the calculation of this Green's function. It appears that in the frequency domain, there are three contributions to the Green's function, namely, from the branch cut, from the quasi-normal modes and the high frequency arcs.
