Abstract:

The discovery of gravitational waves has opened a new window for exploring the universe. The talk will discuss the use of gravitational wave observations for probing dark matter. It will focus on two types of dark matter candidates, WIMPs and ultra-light dark matter. The former can form dark matter spikes around black holes, affecting the motion of compact astrophysical objects through dynamical friction effects, thereby altering the gravitational waveforms emitted by the system, potentially observable by space-based gravitational-wave Laser Interferometers, such as LISA, Taiji and Tianqin. Ultra-light dark matter can directly interact with detectors, influencing the instruments, and can also be probed through gravitational wave experiments.
