How can the orbits of satellite galaxies be used to pin down the mass of the Milky Way?
Stellar streams are an excellent tool for probing the nature of Dark Matter. Today’s paper tests whether Fuzzy Dark Matter is a viable theory by evaluating the thinness of streams in the Milky Way.
Many satellite galaxies in the local universe are orbiting their parent galaxies in highly coherent planes—yet such structures are vanishingly rare in simulations. What gives?
Can dark matter annihilation explain multi-wavelength observations of Andromeda’s galactic center?
… and therefore more powerful. Describing dark matter as a fluid allows us to model dark matter candidates with great accuracy.
What will new data from Gaia reveal about the formation and evolution of stellar streams in the Milky Way?
