Influence radius in the postmerger galaxy at the stalling time, ﹩r^{\prime }_{h}﹩, as function of Q, for initial Dehnen density profiles with ﹩\gamma =0.5﹩, 1.0, and 1.5 (top to bottom), as derived by Merritt (2006) in N‐body simulations (crosses), and by the approximate analytical expression, eq. (A5) (solid lines).
