The Role of Dark Matter in Driving Disk Perturbations: Application to LMC-SMC Like Galaxy Interactions
Himansh Rathore, Hayden R. Foote, Gurtina Besla +6
Dark-matter (DM) models predict that satellite galaxies distort their host's DM halo. As such, both the satellite and the distorted halo can perturb the host's stellar disk. The LM…
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…

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…

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…
The M31-M33 Interaction: Impact on M31's Center of Mass Motion and Satellite Orbits
Ekta Patel, Nicolas Garavito-Camargo, Ivanna Escala
Inspired by recent studies of the Milky Way--LMC interaction and its implications for the Milky Way's global dynamical history, we investigate how the massive satellite galaxy M33…
Shaping the Milky Way: The interplay of mergers and cosmic filaments
Arpit Arora, Nicolás Garavito-Camargo, Robyn E. Sanderson +12
The large-scale morphology of Milky Way (MW)-mass dark matter (DM) halos is shaped by two key processes: filamentary accretion from the cosmic web and interactions with massive sat…
Hypervelocity Stars Trace a Supermassive Black Hole in the Large Magellanic Cloud
Jiwon Jesse Han, Kareem El-Badry, Scott Lucchini +5
Hypervelocity stars (HVSs) are produced by the Hills mechanism when a stellar binary is disrupted by a supermassive black hole (SMBH). The HVS Survey detected 21 unbound B-type mai…
Where do High-Velocity Dark Matter Particles come from in the Milky Way?
Aidan DeBrae, Peter Behroozi, Nicolas Garavito-Camargo
High-velocity particles ( ) in the Milky Way are rare but nonetheless important to characterize due to their impact on dark matter (DM) direct detection experimen…
