Poster Title: Intermediate Age Populations of Globular Clusters in Early-type Galaxies
Abstract: Combined optical and near- infrared photometry is a very powerful tool to detect globular cluster populations which differ in age by several Gyr. We use observed and simulated color- color diagrams for globular cluster systems in early-type galaxies to reveal major star formation episodes which go hand in hand with cluster formation. The relative age of the sub-populations will give evidence for the formation and evolution of the host galaxies. Hereby a possible effect of the environment will be investigated.
