Amplitude of the BH velocity components as a function of time. The figure graphs the velocity dispersion for each parallel and orthogonal component (denoted as σ∥ or ⊥ in the legend) and the (first-order integrated) streaming velocity (v∥, black solid line). The period of a circular orbit at radius R = 1kpc (1.5kpc) is ≃61 Myr (95 Myr).
