| Abstract: |
Strong gravitational lensing by galaxies provides us with a powerful laboratory for testing dark matter models. Various particle models for dark matter give rise to different small-scale distributions of mass in the lens galaxy, which can be differentiated using sufficiently sensitive observations of the lensed images. In my talk, I will discuss the current status of the field, including the most recent results on warm dark matter (WDM), ultra-light dark matter (ULDM), and self-interacting dark matter (SIDM). |
