Test particle simulation of accretion disk at time t = 1 after recoil of the central black hole (see text). In the dimensionless
units of the model, the recoil has νkick = 65 and is inclined 45 degrees to the initial disk axis. This corresponds to 65% of the innermost
orbital velocity. The pre-kick Keplerian orbital period is Pb = 2.28 at the radius Rb = 23.6 where
νKep = νkick.
The orbital period at the
inner and outer boundaries of the initial disk are P = 0.63 and 7.0, respectively.
