The gravitational interactions between the LMC and Milky Way can give rise to dynamical perturbations in MW halo, leading a biased distribution of stellar density other kinematic signals. These disequilibrium phenomena exhibit variations under different parameter combinations MW-LMC model. In this work, we run 50 high-resolution N-body simulations spanning masses halo shapes investigate how LMC-induced evolve with these model parameters. We measure magnitude from mean velocities simulated...
Abstract The gravitational interactions between the LMC and Milky Way cause dynamical perturbations in MW halo, leading to biased distributions of stellar density kinematics. We run 50 high-resolution N-body simulations exploring varying masses halo shapes study evolution LMC-induced perturbations. By measuring mean velocities simulated stars, we identify a discontinuity first-infall second-passage scenarios LMC’s orbital history. In first-infall, Galactocentric latitudinal velocity hovers...
