Left panel: cut through the density of PDM around a Pal 5-like Plummer progenitor at 14 kpc from the Galactic center. The Plummer profile has parameters M = 15 000 M_⊙, Plummer radius = 15 pc, being similar to the King model of our simulation. The Galactic center is at (Z,Y) = (−14,0) kpc on this plot. Right panel: corresponding effective potential of the GC, together with the surface density of the simulated GC particles when the simulated cluster is at the same position as the Plummer model. The lopsidedness is slightly more pronounced in the particles of the simulation than in the isopotentials of the analogous Plummer model.
