Examples of torque profiles as a function of radial distance (in Schwarzschild radii) for BHs embedded in a SG disk. Each plot corresponds to a different combination of torque prescription (top: G24; bottom: B16), disk viscosity parameter α (left: α = 0.01; right: α = 0.1) and SMBH mass (log M_•/M_⊙ = 5.0, 6.3, 7.7, 9.0, represented in different colors). Solid and dashed lines indicate positive and negative net torques, respectively, while shaded regions denote uncertainty in the torque determined by computing it over a range of migrator masses between 5 M_⊙ and 50 M_⊙. Vertical dotted lines mark the locations of migration traps.
