Title News from Wide-Field High Spatial Resolution Studies of Extragalactic Globular Clusters
Abstract

The past decades have greatly advanced our understanding of globular cluster systems through the study of nearby galaxies and galaxy clusters. In most cases, either wide-field observations with ground-based telescopes or single-pointing observations with the Hubble Space Telescope (HST) were used. I will report on recent results from our wide-field observing campaign covering a large area around NGC 1399 using the Advanced Camera for Surveys (ACS) onboard HST. The high spatial resolution of HST/ACS, in combination with rich spectroscopic and X-ray observations, give us a unique new perspective on how globular clusters have formed and evolved in one of the richest globular cluster systems in the nearby Universe.
