By Samuel Grunblatt and others
The vast majority of Milky Way stellar halo stars were likely accreted from a small number (\lesssim3) of relatively large dwarf galaxy accretion events. However, the timing of these events is poorly constrained, relying predominantly on indirect dynamical mixing arguments or imprecise age measurements of stars associated with debris structures....
