Exploring the role of extragalactic globular clusters in shaping galaxy formation: insights from VST/VEGAS, MUSE/LEWIS and future prospects.
Mirabile M., Cantiello M., Iodice E., Paolillo M.
One way to study galaxies is through their globular clusters (GCs) population. Since GCs host a relatively simple (namely single age and single metallicity) stellar population, they are undoubtedly among the simplest astronomical objects after stars. They are often exceedingly numerous (up to tens of thousands in some galaxies), very old (age $t \geq 10$ Gyr) and luminous (so they may be observed out to large distances). The old age makes the GC system a valuable fossil tracer of the formation of a galaxy. Hence, one possible pathway to understand the mechanisms involved in galaxy formation and evolution is through the analysis of their host GCs system. During my talk I will provide a summary of the main results from my master thesis obtained using data from the VST/VEGAS survey, and preliminary results about GC population in ultra diffuse galaxies obtained within the LEWIS project with MUSE@VLT.
