Observational constraint on axion dark matter in a realistic halo profile with gravitational waves
Takuya Tsutsui, Atsushi Nishizawa
Axions are considered as a candidate of dark matter. The axions form coherent clouds which delay and amplify gravitational waves (GWs) at a resonant frequency. That is, the coheren…
