... Programme . ... Abstract: Globular clusters can probe the formation history of galaxies by providing evidence for the chemical evolution and major episodes of star formation in their host galaxies, by examining their kinematic signatures, as well as their structural parameters. ... The giant elliptical NGC 5128 (Centaurus A), at a mere 4 Mpc away, gives us the only opportunity to study in extensive detail the globular cluster system of a recent merger galaxy. ...

... Research . ... I aim to understand the variety of processes that have driven galaxy formation and mass assembly across cosmological history via the resolved (star-by-star) study of nearby systems - in particular the Milky Way and Andromeda (especially their stellar halos and globular cluster populations), the Magellanic Clouds, and the myriad of smaller dwarfs that inhabit the "Local Group".б? . ... Globular clusters are fascinating objects in their own right. ...

Large statistical samples of young stars across star-forming regions are needed to trigger a breakthrough in our understanding, but most optical studies are based on a wide variety of spectrographs and analysis methods, which introduces large biases. ... Because our approach does not rely on spectroscopy, it can easily be applied to homogeneously study the large number of clusters for which Gaia will yield membership lists....

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4ґ5 Gyr than in the sparse ones. ...
