摘要：Ultralight scalars and vectors are popular dark matter candidates.They could extract energy and angular momentum from a Kerr black hole (BH) if the wave length is comparable to the size of BH horizon, forming a sizeable condensate around the host BH. The growth of the condensate, together with its gravitational wave radiation, provides a model-independent strategy to search for these new particles. In this talk, I will introduce the evolution of the BH-condensate system and its gravitational wave emission. The effect of accretion will also be discussed.
