Gravitational Wave as Probes for Self-Interacting Dark Matter

There are many results from observations that support the existence of dark matter, including observations of galaxy rotation curves and gravitational lensing, which robustly support the existence of dark matter. Although there are many research efforts on direct and indirect searches for dark matter. However, the precise characteristics of dark matter, such as its mass and interaction strength with other particles, are still challenging questions. The Cold Dark Matter model has been very successful in large-scale structures, but it could not explain the problem in small-scale structures. Our study focuses on the alternative of self-interacting dark matter that has recently received more attention. Our candidate for self-interacting dark matter in the beyond-standard model could impact the formation of neutron stars and their gravitational wave emission. The gravitational wave could probe the properties of the self-interacting dark matter, especially its mass and coupling. In this talk we present our study on the impact of the self-interacting scalar dark matter on the gravitational wave signals emitted by neutron star binaries.
