Gravitational waves, similar to light, can undergo gravitational lensing when they interact with intervening matter. Recent studies indicate that gravitational-wave lensing may be observed in the coming years as the current gravitational-wave detectors undergo upgrades. However, the methods to detect and employ gravitational-wave lensing are entirely different from light lensing. Indeed, we detect waves instead of particles, with laser interferometers instead of telescopes, and the source population is one of merging black holes. These distinguishing characteristics not only provide valuable insights into our understanding of the universe but also hold promising prospects for the exploration of new applications. Here I will discuss some of our recent work in the field.
