Description
Ultralight dark matter exhibits two types of density fluctuations: coherent and stochastic. Since those fluctuations appear in the different frequency range, the existence of two modes of fluctuations offer a way to probe a wide range of mass of ultralight dark matter, even within a single detector setup. In this talk, I will discuss a few ways to probe ultralight dark matter around the solar system with gravity wave detectors. I will show that current and future gravity wave detectors are capable of probing a few hundred to thousands times local dark matter density near the solar system, which provides one of the best ways to test dark matter at this small scale.
