Star Cluster Formation and Evolution in the Context of the Quiescent versus Violent Star Formation Paradigm

Star clusters are ubiquitous in most galaxies in the nearby Universe, such that star cluster formation is one of the major modes of star formation. In fact, clusters act as robust tracers of the violent star-formation activity in their host galaxies over cosmological time-scales. However, the first few x 107 yr of a cluster population's lifetime are as yet poorly understood. Therefore, if we could obtain robust constraints on the initial conditions for cluster formation and on the importance of their environmental characteristics, this would facilitate a major leap forward in our understanding of the process of star formation itself, and shed light on the main drivers of cluster disruption. Here we propose to bring together astrophysicists with observational, theoretical and numerical modelling expertise in order to tackle these far-reaching issues comprehensively and robustly. We propose to use a combination of ground-based and Hubble Space Telescope observations, which are largely in hand and ready for further analysis. We will do so using a modularised approach, utilising existing observations, and systematically working through the theoretical and numerical problems in tasks that can feasibly and realistically be worked out during three one-week visits to ISSI over the course of a year, with follow-up tasks set for the intervening periods.
