Abstract
Globular clusters in cosmological simulations and in lensed fields: from their birth to the present epoch. Following up on a state-of-the-art, existing set of high-resolution cosmological simulations, we aim to design a new model of a Milky-Way halo with unprecedented features. The new simulations will have sub-parsec resolution down to redshift z~2 and will be among the first in a fully cosmological framework including the feedback of individual stars. At later epochs, the evolution of the system will be followed by means of a cosmological, pure N-body simulation, which will be enough for a realistic description of the dynamical evolution of its sub-systems, in particular the globular clusters. We will compare the structural properties of the simulated clusters (i.e. magnitudes, density and sizes) with a wealth of multiwavelength observational data of the ancestors of present-day GCs in lensed fields. We will create lensed mock images of the simulated objects, a process that will be key for a reliable comparison between our high-level, proprietary data and simulations. We will study the chemical abundance pattern and the kinematical properties of the simulated clusters and compare them with local GCs.
