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…
EXP: a Python/C++ package for basis function expansion methods in galactic dynamics
Michael S. Petersen, Martin D. Weinberg
We present the public release of EXP, a basis function expansion C++ library and Python package for running N-body galactic simulations and dynamical discovery. EXP grew out of the…
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…
The Impact of Feedback-driven Outflows on Bar Formation
Martin D. Weinberg
We investigate the coupling between the temporal variation from galaxy-formation feedback and the bar instability. We show that fluctuations from mass outflow on star-formation tim…
The Effect of the Galactic Spheroid on Globular Cluster Evolution
C. Murali, M. D. Weinberg
We study the combined effects of relaxation, tidal heating and binary heating on globular cluster evolution, exploring the physical consequences of external effects and examining e…
Globular Cluster Evolution in M87 and Fundamental Plane Ellipticals
C. Murali, M. D. Weinberg
The globular cluster population in M87 has decreased measurably through dynamical evolution caused by relaxation, binary heating and time-dependent tidal perturbation. For fundamen…
