MPS Seminar: Testing the cosmological model with dark satellites and bright galaxies (A.Helmi)

The concordance Lambda cold dark matter cosmological model is very successful in describing the Universe on large scales. However, on the scale of galaxies and below it faces some of its biggest challenges. In particular, it predicts that myriads of dark satellites are orbiting in the halos of galaxies like the Milky Way. In this talk I will review the consequences of this fundamental prediction and highlight possible ways of detecting such dark systems through their impact on dwarf galaxies and on stellar streams.
