Spatial distribution of some of the stellar clumps visible in the E − L_z space for the 2 × (1:10) merger. All stellar particles are included in this plot. Top panel: distribution in the E − L_z space, with isodensity contours indicated by colored lines. Four clumps have been identified by eye, they are indicated by the symbols #1, #2, #3 and #4. From the second to the last row: projection on the x − y plane (left column) and on the x − z plane (right column) of stars belonging to each of these clumps, in order of decreasing energy, that is from #1 (second row), to #4 (last row). Their distribution is shown by black contours and is superimposed to the whole distribution of stars.
