Photon frequency conversion induced by gravitational radiation - art. no. 124003

We consider the propagation of gravitational radiation in a magnetized mult icomponent plasma. It is shown that large density perturbations can be gene rated, even for small deviations from flat space, provided the cyclotron fr equency is much larger than the plasma frequency. Furthermore, the induced density gradients can generate frequency conversion of electromagnetic radi ation, which may give rise to an indirect observational effect of the gravi tational waves.
