Description
Axions, or in general axion-like particles, are popular dark matter candidates. They could form Bose-Einstein condensate in our universe. In this talk, I will discuss two different types of condensates: axion stars and black-hole superradiantaxion clouds. These condensates could emit radio-frequency photons as well as gravitational waves. The unique signatures of these signals will also be discussed.
