Abstract
There are two ways to study galaxy formation and evolution: one is to observe a large number of galaxies at a variety of redshifts, the other is to observe in detail just a few nearby galaxies. The precision achievable by the latter method enables the galactic history, including the formation and early evolution, to be studied. Globular clusters provide targets for the second method. We show how the chemical content of Milky Way globular clusters can be used to place them on a timeline charting the history of our Galaxy. The results suggest that different α-elements trace different processes of Milky Way chemical evolution.
