Modelling stellar cluster populations
alongside their host galaxies in a cosmic environment

Stellar cluster populations in the Local Universe show a wide range in
properties, suggesting that these objects form via a unique physical
channel, and that their demographics are shaped by their formation
and evolution in an evolving cosmic environment. This scenario links
the current cluster formation sites in the disks of the the Antennae
galaxies to the old GC population that mostly populates the halo of the
Milky Way, implying that their evolution is tightly coupled to that of
their host galaxy. To understand the observed cluster populations, it
has become necessary the use of numerical simulations that can model the
co-formation and evolution of stellar clusters alongside their galactic
environments over a Hubble time. In this talk, I will explore different
numerical approximations that allow us to model the co-formation and
evolution of star clusters and their host galaxies. Lastly, I will show
that GC populations emerge self-consistently in this scenario after 10
Gyr of co-evolution with their host galaxy and I will briefly discuss how
cluster demographics can be used as diagnosis tools for baryonic models
in galaxy formation simulations.
