Time evolution of the simulated merging process. Left and middle columns: Projections of the simulated GC positions on the x − y and x − z planes for different times (increasing from top to bottom, same as Fig. 1) of the single-accretion simulation with Φ_orb = 60° (MWsat_n1_Φ60, see Tab. 2 for the initial parameters). The in situ clusters are represented by grey circles and the accreted clusters by magenta circles. In the background, the surface density of the totality of the stars of the simulation is also shown. Right column: Distributions of accreted GCs and field stars of the same satellite in the E − L_z space for different times (increasing from top to bottom) of the single-accretion simulation with Φ_orb = 60°.
