Today’s paper uses simulations to understand how the Milky Way’s stellar halo formed, and also asks: what determines the evolutionary pathway taken by a galaxy over cosmic time?
Why are so many modern galaxies not actively forming stars? Today’s guest post by Katherine Lee explores one mechanism that may quench star formation in Milky Way-like galaxies.
Put three supermassive black holes in one simulation and let them fight over the center stage. Will there be a survivor?
When galaxies fall into galaxy clusters, the consequences can be quite epic. But are they more epic with Self-Interacting Dark Matter? Today’s paper suggests the answer is yes. Bite also available in Dutch / Deze Bite is ook beschikbaar in het Nederlands!
Today’s paper looks at two types of lenticular galaxies — seemingly alike, they took very different evolutionary paths.
Today’s guest post takes a look at a technique that cleverly tweaks simulated galaxy halos very early on in their lives in order to direct their growth in a specific way
