Lenient heavy-seed models in BRAHMA simulations produce black hole merger rates above 100 per year and near-unity occupation fractions down to low-mass galaxies, while strict models yield only about 1 merger per year and occupation fractions below 10 percent for galaxies under 10^8 solar masses.

Black Hole Occupation Fraction: Dependence on Black Hole Mass Threshold, Environment, Resolution and Redshift
Black hole occupation fraction rises with stellar mass but its normalization, shape, and redshift trend depend strongly on BH mass threshold, central vs satellite galaxies, simulation box, resolution, and sampled population in the FEGA25 model.

Supermassive Black Hole Assembly from Heavy Seeds with Dynamical Friction in the BRAHMA Simulations: Implications for JWST, LISA, and the Local Universe
Lenient heavy-seed models in BRAHMA simulations produce black hole merger rates above 100 per year and near-unity occupation fractions down to low-mass galaxies, while strict models yield only about 1 merger per year and occupation fractions below 10 percent for galaxies under 10^8 solar masses.
