Modulation of a chirp gravitational wave from a compact binary due to gravitational lensing
Abstract
A possible wave effect in the gravitational lensing phenomenon is discussed. We consider the interference of two coherent gravitational waves of slightly different frequencies from a compact binary, due to the gravitational lensing by a galaxy halo. This system shows the modulation of the wave amplitude. The lensing probability of such the phenomenon is of order 10-5 for a high-z source, but it may be advantageous to the observation due to the magnification of the amplitude.
