Phase spirals across galactic disks I: Exploring dynamical influences on winding

Kiyan Tavangar, Kathryn V. Johnston, Jason A. S. Hunt +4

The vertical phase-space spirals in the Milky Way are clear evidence of disequilibrium. However, they are challenging to study because phase mixing signals evolve under the influen…

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…

The dark matter wake of a galactic bar revealed by multichannel Singular Spectral Analysis

Jason A. S. Hunt, Michael S. Petersen, Martin D. Weinberg +7

The Milky Way is known to contain a stellar bar, as are a significant fraction of disc galaxies across the universe. Our understanding of bar evolution, both theoretically and thro…

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…

Counterculture Stars: Slow and Retrograde Stars with Low-Alpha Disk Abundances

Carrie Filion, Michael S. Petersen, Danny Horta +3

The Milky Way is home to a thin disk that can be defined via kinematics and/or elemental abundances. The elemental abundance-defined thin disk, also called the low-alpha disk, is g…

Dark matter spiral arms in Milky Way-like halos

Marcel Bernet, Pau Ramos, Teresa Antoja +9

The coupling between the dark matter (DM) halo and the stellar disc is a key factor in galactic evolution. While the interaction between structures like the Galactic bar and DM hal…

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…

Action and energy clustering of stellar streams in deforming Milky Way dark matter haloes

Richard A. N. Brooks, Jason L. Sanders, Sophia Lilleengen +2

We investigate the non-adiabatic effect of time-dependent deformations in the Milky Way (MW) halo potential on stellar streams. Specifically, we consider the MW's response to the i…
