"Investigating galaxy evolution using globular cluster systems"

Abstract. The SLUGGS (SAGES Legacy Unifying Globulars and Galaxies Survey) team use globular clusters to probe much further into the outskirts of early type galaxies than is achievable with stellar light. Globular clusters are almost uniformly old and robust to galaxy interactions, allowing us to investigate the assembly history of early type galaxies. My data have unearthed evidence of a very unusual globular cluster subpopulation around a deceptively normal elliptical galaxy. This galaxy, NGC 4365, also shows evidence of tidal interaction with another strange galaxy, NGC 4342. I will talk briefly about what the SLUGG Survey entails and then highlight some of the interesting and puzzling results that I've discovered during my PhD.
