Effect of ultralight dark matter on compact binary mergers
The study modeled how ultra-light dark matter (ULDM) affects compact binary mergers by incorporating accretion and dynamical friction into orbital evolution. Findings show that when ULDM density exceeds $104 ext{ GeV/cm}^3$, merger statistics are significantly altered, leading to faster energy loss and a shift in the peak of merger probability towards higher redshifts, offering an observable signature for dark matter.
