A stellar census in globular clusters with MUSE

Abstract:
Globular clusters (GCs) are now known to have some degree of chemical complexity indicating that they do not consist of a "single" stellar population. Instead, some stars have an atmospheric composition showing evidence of material processed by nuclear reactions. With the Guaranteed Time Observation survey on Globular Clusters performed with MUSE over a time-span of 8 years, we have obtained millions of stellar spectra in more than 30 different GCs. Even though the spectral resolution of MUSE is significantly lower than what is typically used in literature work, the sheer amount of data collected allowed us to gain significant insights on the topic of stellar chemistry and binarity in GCs. In this talk, I will present an overview of our past and current work on these topics.
