Title:

Galaxy simulations with resolved ISM: clustered star formation, globular
cluster formation and IMBH growth

Abstract:

We present recent highlights from the high-resolution simulation project
GRIFFIN which allows to model the galactic turbulent multi-phase
properties of the star forming interstellar medium (ISM). The models
include non-equilibrium heating and cooling processes for the cool/cold
ISM, the realization of individual stars in star forming regions, and
the wind, ionization and supernova feedback from massive stars. We show
with simulations of low metallicity galaxies, that the model reproduces
realistic cold cloud and star cluster properties and that the clustering
properties of massive stars have a strong impact on the formation of
galactic outflows. In starburst environments, the model provides a
self-consistent picture for the rapid hierarchical formation of globular
clusters. In galactic centers with intermediate mass black holes (IMBHs)
we highlight the difficulties to accurately follow accretion due to the
competition between star formation and feedback from an accreting IMBH.
We discuss limitations of the current models and promising ways forward
towards a comprehensive understanding of the connection between ISM
structure, clustered star formation, massive black hole growth and the
launching mechanisms of galactic outflows.
