Description

Gravitational waves emitted from binary black hole mergers exhibit highly distinctive characteristics. When these waves undergo gravitational lensing, the resulting distortions in amplitude and phase can be identified. This phenomenon can thus be leveraged to probe small-scale dark matter structures that are still largely unexplored. In this talk, I will discuss recent advances in this field, including measurements of the small-scale matter power spectrum through lensing.
