Time evolution of the stellar density map of the GLMC disc seen face-on. The panels have a constant time difference of 31 Myr, and the total time evolution is 220 Myr (from t = −0.10 Gyr to t = 0.12 Gyr). All maps are shown in the GLMC in-plane (x′,y′) Cartesian coordinate system. A video version of this figure is available online.
