GA: The dynamics of the Milky Way and the Large Magellanic Cloud – Garavito Camargo
April 22, 2022 @ 10:15 am - 10:30 am
The ongoing interaction with the Large Magellanic Cloud (LMC) is revolutionizing our view of the dynamical state of the Milky Way. The perturbations caused by the LMC open new avenues to test the nature of dark matter. Using results from high-resolution N-body simulations, I will describe the two main perturbations caused by the LMC: the DM wake and the reflex motion. The recent discovery of the stellar wake counterpart of the DM wake opens the opportunity to test the different DM models. I will also discuss how some current challenges to cold dark matter theory, such as the plane of satellites of the MW, are likely natural consequences of the out of equilibrium state due to the MW-LMC interaction.
