IMF spatial gradient (upper panel), the correlation between Γb and the stellar age (middle panel), and the correlation between Γb and the total stellar density (bottom panel). All panels suggest that the IMF slope is only bottom-heavy for the in situ stars, which formed at very high redshift in the first phase of the two-phase formation scenario.
