Gravitational lensing of gravitational wave

Junya Kume

The effect of gravitational lensing on the propagation of gravitational wave (GW) have been extensively studied recently. Since the sensitivity of the GW detector improved and many GW events are now observed, we can have the opportunity to observe "lensed" GW.
In this seminar, I review the basic formulae of the gravitational lensing and explain what is the main difference between the lensing of light and that of GW. Then I briefly explain how this phenomena can affect observational result of GW from compact binary coalescence.
