The nature of the dark matter particle and what underlying particle physics model it relates to remain unknown. I will describe multi-pronged, astronomical investigations of both WIMP and non-WIMP dark matter candidates using radio, X-ray, and gamma-ray data. These studies include tests of the potential dark matter origin of galactic gamma-ray signals in our Galaxy and M31 as well as new investigations of the origin of the 3.5 keV line in clusters of galaxies. I will also discuss the possibility of constraining dark matter self-interaction with dark matter halo shape.
