The Galactic Bulge represents the oldest massive component of the Galaxy but its formation mechanism remains an extremely debated subject. A detailed characterization of the Bulge Globular Clusters is one of the most promising ways to shed light on this topic. Having ages of 12-13 Gyr, they are direct witnesses of the bulge formation epoch, but they could also be fossil remnants of primordial sub-structures that merged to generate our spheroid (as suggested for Terzan 5 and Liller 1).
With the final aim of providing the accurate characterization of the stellar populations in each of the investigated Bulge Globular Clusters, my Phd project is based on a high-resolution, multi-wavelength (NIR and OPT) and multi-epoch photometric analysis of these stellar systems by exploiting the superb capabilities of GSAOI-GEMS at GEMINI, HST and JWST.
