Paper day! Izzy Gray proposes a new model for NSC formation in very low mass dwarfs. Model prediction: NSCs should have CMDs with >2, distinct, main sequence turnoffs. Some nearby CGs like OCen and M54 show exactly this behaviour, suggesting they could be accreted NSCs! 🔭

EDGE: A new model for Nuclear Star Cluster formation in dwarf galaxies
Nuclear Star Clusters (NSCs) are amongst the densest stellar systems in the Universe and are found at the centres of many bright spiral and elliptical galaxies, and up to ${\sim}$40% of dwarf...
