Galaxy Deconstruction: Clues from Globular Clusters
Abstract
The present-day globular cluster populations of galaxies reflect the cumulative effects of billions of years of galaxy evolution via such processes as mergers, tidal stripping, accretion, and in some cases the partial or even complete destruction of other galaxies. If large galaxies have grown by consuming their smaller neighbors, or by accreting material stripped from other galaxies, then their observed globular cluster systems are an amalgamation of the globular cluster systems of their progenitors. Careful analysis of the globular cluster populations of galaxies can thus allow astronomers to reconstruct their dynamical histories.
