Gravity seminar : Otto Hannuksela, The Chinese University of Hong Kong — Gravitational-wave lensing

Gravitational waves, similar to light, can be lensed by massive celestial bodies, encoding lensing signatures within their precisely modelled waveforms. Recent forecasts by several independent groups have predicted gravitational-wave lensing to become an observable reality as the current gravitational-wave detectors are upgraded. This anticipation has spurred a global effort to develop methodologies to capture the various gravitational wave signatures produced by gravitational lensing. It has furthermore expedited the development of a rich science case. In this talk, I will introduce select recent works on gravitational-wave lensing.
