We conclude that the number of GCs around DF44 is as expected for regular dwarf galaxies of similar stellar mass and DF44 is not extraordinary in this respect.

The kinematics of local thick discs do not support an accretion origin

no code implementations29 Jan 2019 Sébastien Comerón, Heikki Salo, Johan H. Knapen, Reynier F. Peletier

Literature numerical studies of dynamical friction allow us to estimate that at the current cosmic time about one in six mergers for which the stars of the accreted galaxy ended in a thick disc were retrograde.
