Modulation of a Chirp Gravitational Wave from a Compact Binary due to Gravitational Lensing
arXiv:astro-ph/0505116 · doi:10.1103/PhysRevD.71.101301
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.
