Description
The strong gravitational fields around black holes may be the best (and only) way to probe the nature of dark matter, if it is ultralight. Gravitational waves provide us with the cleanest channels into those regions.
In my talk, I will discuss what current LVK observations can tell us about the presence of ultralight bosons around black hole binaries. I'll also argue that future gravitational-wave observations have the potential to detect and measure the mass of an ultralight dark matter particle to high precision.
