Ellipticity vs. specific angular momentum λ_Re of the NSCs in the 6 Fornax cluster galaxies (filled squares, uncertainties are smaller than the symbols) are compared with GCs in the Milky Way (Kamann et al. 2018, open circles represent GCs for which the kinematics data do not reach the half-light radius and λ_Re is measured within the available maximum extent). The coloured symbols represent the values derived from the two simulated NSCs, described in Sect. 5; the dotted line connects measurements with the same viewing angle. The dashed line denotes the separation line between slow- and fast-rotating galaxies (Emsellem et al. 2011).
