Present day distribution of simulated GSE stars evolved in a tilted, light disk potential (top panels) and a tilted, growing disk potential (bottom panels) in three projections. In the latter case, the disk grows up to six times heavier than its initial mass. Despite the addition of this massive disk to the potential, the tilt of GSE persists over 5 Gyr.
