Discovering the building blocks of nuclear star clusters
Today’s paper combines new observational data from Gaia with 20 years of multi-wavelength data of the compact dwarf galaxy NGC 5253, reveal a triplet system of star clusters in the centre.
Shaken, Not Stirred: Subgrid Metal Diffusion in Galaxy Simulations
A lot of physics happens below the resolution limit of galaxy simulations that must be represented with “subgrid” models. Today’s paper shows the importance of including a subgrid model for the mixing of metals in galaxy simulations.
