Spiral Structure Properties, Dynamics, and Evolution in MW-mass Galaxy Simulations
J. R. Quinn, S. R. Loebman, K. J. Daniel +8
The structure of spiral galaxies is essential to understanding the dynamics and evolution of disk galaxies; however, the precise nature of spiral arms remains uncertain. Two challe…
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…
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…
Response of the LMC's Bar to a Recent SMC Collision and Implications for the SMC's Dark Matter Profile
Himansh Rathore, Gurtina Besla, Kathryne J. Daniel +1
The LMC's stellar bar is offset from the outer disk center, tilted from the disk plane, and does not drive gas inflows. These properties are atypical of bars in gas-rich galaxies,…
