Electromagnetic Timing Priors in Gravitational Wave Forecasts for Ultralight Dark Matter

Ultralight dark matter (ULDM) can induce a slow frequency modulation of nearly monochromatic millihertz gravitational waves (GWs). Existing forecasts infer the carrier phase evolution from the GW data, leaving the modulation partially degenerate with the binary frequency derivatives. We incorporate the electromagneti...
