讲座内容：

Thestandard cosmological model, the ‘Λ cold dark matter’ model (ΛCDM) is verysuccessful in describing the formation and evolution of large-scale structurein the Universe. However, the standard model is being challenged byobservations on small scales, such as those of our Local Group, where thenature and properties of dark matter are most clearly manifest. The Local Groupis an association of galaxies that consists of our own Milky Way (MW), theneighbouring Andromeda, as well as hundreds of smaller dwarf galaxies. Itsproximity and abundance of observational data offer an unmatched window intothe physics of the Universe, such as understanding galaxy formation andevolution at the faint end and of one of the most compelling problems inphysics, the nature of dark matter. In the next decade, we will witness an explosionin the number of dedicated surveys such as GAIA, WEAVE, 4MOST and LSST, whichwill allow us to probe galaxy formation and the underlying dark matterdistribution to an even greater detail. In this talk, I will present my latestwork based on the state-of-the-art numerical simulations. In particular, I willdiscuss what the orbits of the Milky Way (MW) satellites can tell us about theshape and orientation of the MW dark matter halo.
