Stellar Populations (and application to globular clusters)

Star clusters are often considered the basic building blocks of today's large spiral and elliptical galaxies. Star clusters and their stellar populations play a significant role in the context of galaxy evolution, across space (from local to high redshift) and time (from currently forming to fossil remnants). We are now within reach of answering a number of fundamental questions that will have a significant impact on our understanding of key open issues in contemporary astrophysics, ranging from the formation, assembly and evolution of galaxies to the details of the star-formation process. Here, we will look at the details of the stellar popultions making up the old globular cluster systems, and consider the implications in a wider context.
