Description

The Milky Way’s (MW) most massive satellite, the Large Magellanic Cloud (LMC) has just passed its first pericenter approach. The presence of the LMC has a considerable impact on the position and velocity distributions of DM particles in the MW. This directly affects the expected DM annihilation rate, especially in the case of velocity-dependent annihilation models since the LMC may boost the relative DM velocity distributions. I will discuss the impact of the LMC using MW-LMC analogues in the Auriga magneto-hydrodynamical simulations.
