Self-Interacting Dark Matter-Induced Dynamical Friction and Its Imprint on EMRI Gravitational Waves

Extreme-mass-ratio inspirals (EMRIs) provide a promising probe of the dark matter environment surrounding massive black holes through their long-duration gravitational-wave signals. In this work, we investigate the influence of self-interacting dark matter (SIDM) on EMRI dynamics and gravitational-wave phase evolution....
