Mdyn/Mreal versus look-back time for simulated TDGs. Mdyn is the dynamical mass inferred from the mean rotation velocity of gas particles, while Mreal is the mass obtained by adding gas, stars, and DM particles within the TDG radius. The time t = 0 corresponds to the snapshot of the simulation that reproduces the present-day large-scale properties of the interacting system. Red dots are TDGs formed in the tidal tails of a standard disc-disc merger that resembles NGC 7252. Black crosses are TDGs formed in a collisional H I  ring that matches the properties of NGC 5291 (B07).
