The gravitational wave and radio signals of ultralight dark matter

Abstract

We study the new approaches to explore the ultralight (axion) dark matter by gravitational wave experiments and radio telescope based on the superradiance process around Kerr black hole and the resonant conversion process in the magnetosphere of neutron star or the Sun.
