The Milky Way - Large Magellanic Cloud Interaction with Simulation Based Inference
Richard A. N. Brooks, Jason L. Sanders, Vedant Chandra +4
The infall of the Large Magellanic Cloud (LMC) into the Milky Way (MW) has displaced the MW's centre of mass, manifesting as an observed reflex motion in the velocities of outer ha…
Quantifying the Milky Way, LMC and their interaction using all-sky kinematics of outer halo stars
Richard A. N. Brooks, Jason L. Sanders, Adam M. Dillamore +4
The recent pericentric passage of the Large Magellanic Cloud (LMC) has dislodged the Milky Way's (MW) centre of mass, inducing dynamical disequilibrium, the reflex motion, in the k…
Mapping the Distorted Dark Matter Distribution of the LMC-SMC System Prior to Milky Way Infall with Basis Function Expansions
Hayden R. Foote, Himansh Rathore, Gurtina Besla +6
The SMC orbits within the LMC's dark matter (DM) halo in a 1:10 mass-ratio encounter. The LMC:Milky Way (MW) interaction is also 1:10, and is expected to perturb the MW…
A Simulation Based Inference Approach to the Dynamics of the MW-LMC System -- Validation
Richard A. N. Brooks, Jason L. Sanders, Adam M. Dillamore +2
The infall of the LMC into the Milky Way (MW) has generated dynamical disequilibrium throughout the MW. The interaction has displaced the MW's centre of mass, manifesting as an app…
Stellar Birth Radii in the LMC: Insights into Chemodynamics, Radial Migration, and Star Formation Across the Disk
Yuxi Lu, Bethany Garver, David L. Nidever +4
The LMC and SMC are interacting dwarf galaxies that offer a valuable testbed for studying the effects of galactic mergers. We investigate the chemodynamic history of the LMC in the…
Shaping the Milky Way. II. The dark matter halo's response to the LMC's passage in a cosmological context
Elise Darragh-Ford, Nicolas Garavito-Camargo, Arpit Arora +15
The distribution of dark matter in the Milky Way (MW) is expected to exhibit a large-scale dynamical response to the recent infall of the LMC. This event produces a dynamical frict…
