An Alternative Channel for High-mass Binary Black Holes-Dark Matter Accretion onto Black Holes

By a method of population synthesis we construct a model of dark matter (DM) accretion onto binary black holes (BHs) and investigate the merger rate of the binary BHs. We find that the merger rate can weakly increase (less than 10%). However, the DM accretion can efficiently enhance the masses of bi...
