Dancing Streams In Merging Halos: Stellar Streams in a MW--LMC-like merger

Sachi Weerasooriya, Tjitske Starkenburg, Emily C. Cunningham +1

Stellar streams -- formed from tidally stripped globular clusters or dwarf galaxies -- are sensitive tracers of a galaxy's accretion history and gravitational potential. While nume…

Kinematic Signatures in the Stellar Halo from Cosmological Encounters between the Milky Way and its Clouds

Mia Mansfield, Robyn Sanderson, Daniel Hey +4

Recent theoretical and observational analysis of the interaction between the Milky Way (MW) and LMC suggest that it has a significant dynamical impact on the MW's stellar halo. We…

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…

All-Sky Kinematics of the Distant Halo: The Reflex Response to the LMC

Vedant Chandra, Rohan P. Naidu, Charlie Conroy +11

The infall of the Large Magellanic Cloud (LMC) is predicted to displace the inner Milky Way (MW), imprinting an apparent 'reflex motion' on the observed velocities of distant halo…

Efficient and accurate force replay in cosmological-baryonic simulations

Arpit Arora, Robyn Sanderson, Christopher Regan +8

We construct time-evolving gravitational potential models for a Milky Way-mass galaxy from the FIRE-2 suite of cosmological-baryonic simulations using basis function expansions. Th…

Bar formation and destruction in the FIRE-2 simulations

Sioree Ansar, Sarah Pearson, Robyn E. Sanderson +5

The physical mechanisms responsible for bar formation and destruction in galaxies remain a subject of debate. While we have gained valuable insight into how bars form and evolve fr…
