2D histograms of the simulated Gaia–Sausage–Enceladus (GSE) stellar distribution in N21 in three projections, adopting an asinh stretch that is normalized to include 98% of the sample. All following figures with 2D histograms adopt the same color scheme. The top and bottom panels show the stellar distribution at lookback time t _lb = 5 Gyr and present day, respectively. These panels show that the tilt in the stellar distribution of the simulated GSE persists over 5 Gyr.
