Cluster and Galaxies
- Romeel Dave (University of Edinburgh)
Metals are produced in galaxies as a result of processes associated with the stellar life cycle and will accumulate as galaxies assemble their stellar mass. The metal content of galaxies therefore provides a fossil record of the history of star formation, but also feedback and galaxy-scale gas flows. Measuring chemical abundances in galaxies are thus a powerful tracer of the assembly of...
We introduce a new chemical enrichment and stellar feedback model into GIZMO, using the SIMBA sub-grid models as a base. Based on the state-of-the-art chemical evolution model of Kobayashi et al., SIMBA-C tracks 34 elements from H→Ge and removes SIMBA’s instantaneous recycling approximation. Furthermore, we make some minor improvements to SIMBA’s base feedback models. SIMBA-C provides...
Globular clusters (GC) constitute a rather unique probe of galactic and stellar evolution theory, but their formation and peculiar chemical patterns are still not completely understood.
The most striking feature is the presence of multiple stellar populations, showing strong star-to-star variations in light element abundances. The distribution of heavier elements is instead constant across...
