Today’s guest post looks at the surviving galactic subhalos in simulations.
A satellite of Andromeda is missing an important ingredient — so where did it go?
The Fault in our Star (Populations): Solving the Multiple Stellar Populations Problem with Dark Matter
Globular clusters have puzzled astronomers with the presence of different distinct populations of stars; is dark matter a possible solution to this problem?
In the latest of our #UndergradResearch series, discover how Emily Silich used observations from the HaloSat cubesat to search for X-ray signatures of dark matter.
How can the first stars tell us about the nature of dark matter?
Today we interview Dr. Scott Tremaine, who is giving the career-capping Henry Norris Russell lecture, which will feature insights into cosmic dynamics on scales ranging from comets to galaxy clusters.
