LMC Calls, Milky Way Halo Answers: Disentangling the Effects of the MW--LMC Interaction on Stellar Stream Populations

Understand

The infall of the LMC into the Milky Way (MW) has dynamical implications throughout the MW's dark matter halo.

• We study the impact of this merger on the statistical properties of populations of simulated stellar streams.
• Specifically, we investigate the radial and on-sky angular dependence of stream perturbations caused by the direct effect of stream--LMC interactions and/or the response of the MW dark matter halo.
• We use a time-evolving MW--LMC simulation described by basis function expansions to simulate streams.
