Abstract : The gravitational bending of light was the first observational test that heralded the remarkable success of Einstein’s General Theory of Relativity. In the last few decades, gravitational lensing has emerged as a powerful tool for astronomy. Gravitational waves (GWs) are also expected to be lensed similarly to light. Over a hundred GW signals from coalescing compact binaries have been observed by LIGO and Virgo so far. In the next few years, thousands of such observations are expected. Some of these GWs will be lensed by intervening objects such as galaxies and compact objects. This talk will summarise the prospects of detecting lensing signatures in GWs and will discuss some of the potential new probes such observations will enable.
