Description
Discrepancies between observations of galactic rotation curves and theoretical predictions suggest the existence of dark matter. Although numerous experiments have failed to detect weakly interacting massive particle (WIMP) dark matter, dark matter exhibits gravitational interactions with celestial bodies, and its high-density accumulation in strong gravitational systems such as black holes definitely leaves observable signatures. With the advancement of gravitational wave detection and black hole shadow imaging, detecting dark matter using these tools has become feasible. Scalar fields are important dark matter candidates. Theories indicate that they undergo high-density condensation near black holes under gravitational effects, making the study of their dynamical properties in the black hole background crucial. This report will introduce the impact of scalar dark matter on binary black hole mergers, calculate the corresponding gravitational wave signals, and analyze the influence of the intrinsic parameters of scalar fields on the dynamical properties of black holes, among other aspects.
