Gravitational lensing of gravitational waves

Abstract: Gravitational lensing has now become an unavoidable tool in astrophysics. Like lensing of electromagnetic waves, matter distribution between the gravitational wave (GW) source and the detector can act as a gravitational lens and produce multiple GW images. Lensing of GW signals leads to the amplification of the signal and increases the signal to noise ratio. Unlike EM waves, the wavelength of the gravitational waves is comparable to the Schwarschild radius of the lens which leads to some interesting effects such as interference and diffraction. In this talk I will discuss such possible effects of lensing of gravitational waves that could be observed with current and next generation gravitational wave detectors.
